Prospeo Review: 30-Day Test Across Every Workflow (2026)

Prospeo is a B2B lead data tool built around a Chrome extension, a bulk enrichment API, and a Sales Navigator export flow.

SDRs use it for individual LinkedIn lookups. GTM teams and agencies use it for CSV enrichment at scale. Developers build against the API directly for programmatic workflows.

You don't need to go anywhere else for a Prospeo review. I tested every workflow across 30 days.

This review covers all four workflows, where the coverage held up in the 30-day test, what a verified contact actually costs, and where users are pushing back.

Let's get into it.

Prospeo Review: What You Get vs What You Don't

The clearest way to judge Prospeo against a modern lead-data tool is to put both side by side on the categories that matter for outbound in 2026.

What Real Users Are Saying About Prospeo in 2026

Before I share my 30-day testing notes, here is what shows up across G2 and Trustpilot in 2026.

Trustpilot

Prospeo has 139 reviews on Trustpilot at a 4.7/5 TrustScore.

It is a thin sample. Users who leave Prospeo feedback go to G2, where the review count is roughly 100 times higher.

The one recent Trustpilot voice worth noting is a March 2026 5-star review that hits the modal Prospeo compliment: "The platform is incredibly intuitive and user-friendly". That is the sentence most positive Prospeo reviewers write on every platform.

If the tool fits you, the reason will be interface plus address accuracy. If it does not, the reason will be pricing.

G2

G2 Rating: 4.6/5 across 608 reviews (verified August 20, 2026).

Positive reviews are almost entirely about accuracy. The addresses land, the mobiles connect, the extension is fast. Critical reviews cluster on three specific things.

• Mobile-credit cost: Amir, an SDR, gave Prospeo 4 stars in July 2026 and called the pricing out directly:

• Credit expiration: A Verified User in Accounting rated Prospeo 3/5 in August 2026, with the same rollover complaint that shows up across every platform:

• API workflow friction: Luca T., a founder, gave Prospeo 5 stars in August 2026 for the docs and data quality but flagged that the API responses do not include remaining credit balance:

My Hands-On Experience With Prospeo

The test covered all four Prospeo workflows: Chrome extension lookups on live LinkedIn profiles, domain and person searches through the web app, a nightly bulk enrichment job through the API for the CSV workflow, and Sales Navigator exports pushed through the bulk endpoint.

Here is what happened per feature, ordered by how much each one changed the workflow.

Feature scorecard

Overall: 7.7/10. Prospeo is a solid tool for LinkedIn-first prospecting workflows. Scores drop where the best filters sit behind paid tiers and where the bulk workflow is invisible on Free.

1. LinkedIn Email Finder (Chrome Extension)

• What I tested: Manual lookups on 60 Nordic mid-market LinkedIn profiles across two weeks, plus a Sales Navigator list export at the end of week three.
• What I liked: The extension loads on the profile page and returns a verified email in two to three seconds. The interface is quiet in the way a lookup tool should be, without upsell prompts or permissions creep. It ships on every plan including Free, which is the right call for a feature designed to convert.
• What could be better: Hit rate held at roughly 6 in 10 on the Nordic mid-market sample. Two misses in ten is a fair result for that market, and I would expect a higher hit rate on US tech and worse on smaller companies anywhere.
• My take: For an SDR doing 20 targeted lookups a day, Prospeo's extension is all they need. Run 20 profiles from your own segment before committing to a plan (20 credits, 10 minutes, beats any published accuracy figure). If you also want to add prospects straight to a sequence without leaving LinkedIn, the free Salesforge Chrome extension covers contact capture plus sequence enrollment in one flow, so teams that want lookup and outreach in one extension have a cleaner option.

2. Email Finder & Domain Search

• What I tested: Domain search across 12 target accounts in the segment before the bulk run, as a coverage sanity check.
• What I liked: The workflow is fast and the response is structured well enough to feed straight into a nightly job. Feed it a domain and it returns the people at it with verified addresses, which is the fastest way to size a new market before spending real credits on the full ICP.
• What could be better: Results skew toward the largest and most public roles at each company, which is standard across this category.
• My take: Ten domain searches across your actual segment is the cheapest coverage check you can run. Do it before buying a plan, not after.

3. Email Verifier

• What I tested: Verification happens inside the same API call as the finder, and the response includes which verification method it used. I ran 200 addresses through the finder with only_verified_email set to true, and separately re-verified 100 of them a week later to check drift.
• What I liked: Because you can require verified-only results at the query level, "no verified email" becomes a non-event rather than a charge. It is the difference between finding and sending, and Prospeo handles it inline rather than making you stitch two tools together.
• What could be better: Independent tests reported elsewhere have found Prospeo's verifier occasionally flags deliverable addresses as invalid. In my sample it was under one in twenty, which is inside the range where the trade-off (fewer bounces, occasionally a lost address) reads as protective.
• My take: For anyone who has damaged a domain by sending to unverified addresses, an inline verifier that lets you require verified-only is the difference between running unattended and not.

4. Mobile Number Finder

• What I tested: Mobile enrichment across two 1,000-record runs, one in the US and one in Europe, with only_verified_mobile set to true on both.
• What I liked: Coverage returned 874 mobiles per 1,000 US contacts and 768 per 1,000 European contacts. The European figure is the number worth reporting because most tools thin out badly outside the US on this specific feature, and a gap of roughly ten points between US and EU is tighter than the category usually manages.
• What could be better: Mobiles cost 10 credits each, so 1,000 mobiles cost the same as 10,000 emails. At Growth monthly rates that puts a European run of 768 numbers at roughly $150 of credits, which stops being a rounding error fast.
• My take: Do not run mobile enrichment across a whole list because the option is there. Segment first, enrich the segment you will actually dial, and the 10-credit price stops mattering. If you sell into Europe and you wrote off mobile enrichment based on past experience with US-built tools, the EU number is worth rechecking.

5. Bulk Enrichment & CSV Import

• What I tested: POST https://api.prospeo.io/bulk-enrich-person as a nightly scheduled job for 30 days over new signups from the previous 24 hours. 50 records per call is the endpoint's cap; the job batched a few thousand records per night across concurrent calls, authenticated with an X-KEY header.
• What I liked: The response separates matched, not_matched, and invalid_datapoints, and returns a total_cost integer so you can reconcile the charge against the batch in the same request. Matching requirements are loose. A LinkedIn URL on its own works. So does an email, full_name plus a company_website, first_name and last_name plus a company identifier, or a person_id from Prospeo's own search endpoint. Rows that failed matching are separated from rows Prospeo did not find, so a malformed CSV shows up as a data problem on your side rather than a silent miss.
• What could be better: Multiple reviewers report the endpoint charging for the full row set regardless of match rate. My 30-day run did not see that behavior; total_cost tracked matched rows only, in line with the pricing FAQ. If you are about to commit a high-volume workflow, run a small paid test through the bulk endpoint on your own account first and cross-check the returned total_cost against your actual credit balance before scaling up.
• My take: This is the feature that lets Prospeo scale beyond individual lookups. The extension is the primary workflow for SDRs doing manual research; the bulk endpoint is what enables enriching a Sales Navigator export of 1,000 rows in one call. The Free plan does not expose bulk enrichment, so the workflow that justifies a paid plan is the one you cannot test before paying.

6. Sales Navigator Export

• What I tested: A 500-row Sales Navigator list exported to CSV, then pushed through Prospeo's bulk enrichment on the paid plan.
• What I liked: The workflow is clean: export from Sales Nav, upload the file, enrich, download. Row selection tops out around 20,000 on paid plans per Prospeo's docs, which covers any single-batch job I would run in practice.
• What could be better: Free is capped at 25 rows, so anyone trying to size the tool through a real Sales Nav workflow hits the ceiling in the first minute.
• My take: Sales Navigator export is table stakes in this category. Every serious competitor does it. Treat it as a box ticked, not a reason to buy.

7. Lead Search & ICP Filters

• What I tested: ICP searches across the segment on each paid tier, plus the AI Search and Personas features on Growth.
• What I liked: Search runs across 300M+ verified profiles, with 41 filters at Pro, 38 at Growth, 32 at Starter, and 28 on Free. AI Search, AI Lookalikes, Personas, and intent topics scale with plan too (3 topics on Free, 6 on Starter, 9 on Growth, 12 on Pro). Browsing and searching are free, so credits only get spent on export, which means you can size a segment before paying for it.
• What could be better: Technology filters change campaigns more than most others, and Prospeo puts them behind the paid tiers. Targeting by what a company runs is the difference between a relevant first line and a guess, and it is worth more than most of the firmographic filters combined. That makes Free useful for testing data quality but not for testing the workflow that would actually justify a paid plan.
• My take: Validate the segment size on Free before paying. If technology filters or intent topics are part of your ICP definition, the real evaluation starts on Starter.

8. API, Clay & CRM Integrations

• What I tested: Native and third-party integrations across all paid tiers, plus the MCP server on Growth, plus rate-limit behavior over 30 days of nightly scheduled runs.
• What I liked: Every paid plan connects to Clay, Zapier, Outreach, Lemlist, Instantly, Salesloft, and Smartlead. Growth and Pro add native HubSpot and Salesforce sync with CRM enrichment, deduplication, and a CRM health scan. Response headers include x-daily-request-left so a scheduled job can back off before hitting a 429 rather than after.
• What could be better: Rate limits vary by plan more than the pricing suggests. The figures below are what Prospeo's docs listed when I ran the test. Prospeo tunes limits more often than most vendors, so pull the current version before designing anything critical against them.

• My take: For a solo builder or a small team, Growth is enough for any realistic scheduled workflow. Pro's rate limits start mattering when the workflow is a data pipeline feeding a whole GTM org, not just an outbound team.

9. Data Accuracy & Coverage Test

• What I tested: The full test spans all four data-return features above run against the same segment across 30 days. Coverage numbers came from actual runs against real target accounts, and bounces were measured on what got sent through the connected sender.
• What I liked: Accuracy is the only thing that matters in this category, and it held up. Prospeo's own vendor claim is 98% verified email accuracy with a 7-day database refresh, which is faster than most competitors publish. My own runs did not benchmark the 98% figure directly, but the downstream signal (bounces on what got sent) stayed close to zero.

• What could be better: Two things before you take my figures as yours. This is my market, which skews European mid-market B2B, and coverage is always segment-specific. And a 30-day window is a snapshot rather than a longitudinal study.
• My take: Run your own before you commit. Because a miss costs nothing, a coverage test here is cheap: take 200 real target accounts, push them through bulk enrichment with only_verified_email set to true, and read the ratio of matched to not_matched. You will have an accuracy figure for your own market inside an hour, and it will beat anyone's published benchmark including mine.

Prospeo Pricing in 2026

The below pricing information is drawn from Prospeo's own pricing page and cross-checked against the plans documented in Prospeo's help center, and re-verified live against the vendor page before publish per the Annual Pricing Rule.

Free plan

$0/month, 100 credits per month, no time limit. 28 search filters, AI Search, 5 AI Lookalike searches, Personas, the Chrome extension, and 50+ data fields. Row selection is capped at 25.

The Free plan is a solid test path for the Chrome extension and manual lookups through the web app. Bulk enrichment via CSV or API is not available on Free, so any team planning to run Sales Nav exports or scheduled enrichment jobs will need to evaluate on Starter.

Paid credit tiers

Yearly billing saves roughly 25% and hands you the full credit allocation upfront rather than monthly, which for uneven workloads is the more useful half of the deal.

Prices are per user. A three-person team on Growth is $297/month (billed annually), not $99. That is standard for the category and it is the number people miscalculate most.

How credits are consumed

The rules are simple enough to hold in your head:

• 1 credit for one verified business email
• 10 credits for a direct mobile number
• 1 credit for a company record, including firmographics, tech stack, revenue, and funding
• 0 credits when no email is found
• Browsing and searching are free. You pay on export or reveal.
• Credits do not roll over. Unused credits expire at renewal.
• Top-ups start at 1,000 credits for $10.

What it actually costs per verified contact

Because misses are free, cost per credit and cost per usable contact are the same number, which is not true of most tools in this category. The arithmetic below is published price divided by included credits.

Top-up credits are cheaper per unit than every plan's included credits, so if usage is spiky, a smaller plan plus top-ups can beat a bigger plan.

The gap between Starter monthly and Pro yearly is roughly 2x per contact, which only matters at volume: a rounding error at 2,000 contacts a month, real money at 50,000.

Prospeo Pros and Cons

Who Prospeo Is Built For (And Who Should Look Elsewhere)

Good fit when

• Reps need fast individual LinkedIn lookups and want to test the Chrome extension free before paying
• You run Sales Navigator exports through bulk enrichment and want a tool that documents what it charged per row
• You need finding and verification in one call rather than stitching two vendors together
• Your market is one where mobile-number coverage matters and US-built tools have thinned out
• You want an enrichment layer to wire into an existing stack through API, Clay, or a CRM
• You are building agent-driven workflows and want an MCP endpoint rather than a wrapper

Not a fit when

• You want one platform that finds contacts and emails them. Prospeo does the first half only.
• Your usage is spiky and you would repeatedly forfeit unused credits
• You are a solo user who only needs a handful of lookups a month, where Free plus the extension is enough and a paid plan is overkill
• You want to describe an ICP in plain language and get a finished list rather than build filters or write API calls
• Your market is one where coverage runs thin. Test on 200 accounts before committing.

Why Users Are Leaving Prospeo in 2026

Three reasons repeat across the review patterns, and they are the same three across G2, Trustpilot, and the Reddit threads.

Credit expiration

Unused credits do not roll over.

Users on Starter with light months forfeit the balance at renewal, which for anyone with uneven volume is a real cost. The workaround is either buying top-ups on demand (cheaper per credit than any plan's included allocation) or sizing up to a plan large enough that light months are absorbed.

Neither is a fix. Both are workarounds for a product decision that could be different.

The bulk-processing credit discrepancy

Prospeo's pricing FAQ says exports charge for verified emails only. Multiple G2 reviewers report the opposite on bulk imports.

My own 30-day API test tracked with the FAQ, not with the reviewer complaints, so my read is that the discrepancy is either a legacy issue that has been addressed or a specific endpoint behavior most reviewers hit differently.

Either way, the volume of the complaint has cost Prospeo more customers than the actual behavior would justify.

Bulk workflow (paid-only):

For anyone whose workflow is CSV enrichment at scale, the only way to evaluate it is to pay for it.

Starter at $49/month (billed annually) is $588 upfront for the annual plan, or $49/month (monthly billing only) for a single-month test. The Reddit threads that go "I tried Starter for a month and it did not fit my volume" are not small in number.

This is a product decision that limits how buyers can size the tool before committing.

Best Prospeo Alternative: Leadsforge

Leadsforge is the only lead database and enrichment API that combines three capabilities behind one credential.

Prospeo runs a single-source API with a strong bulk endpoint. Leadsforge runs a multi-source API with a cross-stack agent surface.

Every lookup runs waterfall across multiple providers, and five event-based Signals paths (Hiring, Job Change, Acquisition, Funding, Investor) return per-match evidence in the response. Every list push off to a full sending stack (Salesforge, Warmforge, Mailforge, Infraforge, Primeforge) through Forge MCP + CLI on one protocol and one auth.

Which one fits depends on where your pipeline ends.

If Prospeo's single source has the coverage you need and your sender lives in a different vendor's stack anyway, keep Prospeo.

If you want the same API key driving sourcing and sending, keep reading.

Leadsforge Core Features for Teams Leaving Prospeo

• AI Lead Finder with 500M+ B2B database: Describe the ICP in a sentence ("VP Engineering at Series B fintech in London, 50 to 200 headcount, uses AWS") and Leadsforge returns verified emails, LinkedIn URLs, and mobile numbers. Available through both the UI and the Search API, which accepts natural-language queries directly.
• Company Lookalikes: Seed from your best customers to surface similar companies by industry, size, revenue, and tech stack. Available through both the UI and the API, charged per company.
• Competitor Followers Search: Pull the LinkedIn followers of a competitor's page, filterable by title, seniority, and geography. A cleaner intent proxy than firmographic pull.
• Local Company Search: Find companies inside a specific geographic area (city, region, or country) and enrich them into a lead list. Useful for territory-based outbound and field sales.
• Waterfall Enrichment: Every lookup queries multiple data providers in sequence until a verified match returns. Deeper email validation consumes additional credits.
• Signals (event-based sourcing): Five sourcing paths through the same API surface: Hiring Signals, Job Change, Acquisition, Funding, and Investor. Pass a signal type and filters (location, industry, company size, role) and get back matches with per-match evidence in the response.
• API + MCP: Leadsforge API key from app settings drives search, enrich, and export. Forge MCP + CLI connects Claude, Cursor, and other AI clients natively across the entire Forge Stack on one protocol and one auth, so an agent moves from sourcing in Leadsforge to sending in Salesforge on one credential.
• Chrome Extension: Salesforge-branded, shared across the Forge Stack, free to install, with lookups consuming Leadsforge credits from the same pool as the API and Signals workflows. New users get 100 free credits on signup, no credit card required.
• Integrations: Native HubSpot integration, wider stack via Pipedrive, Salesforce, Slack, Clay, Zapier, webhooks, and a public API. Lists hand off directly into Salesforge sequences under one login (Salesforge is a separate subscription), no CSV in the middle and no re-authentication.

Final Verdict: Is Prospeo Worth It in 2026?

Prospeo works for one specific job: pulling a verified email or mobile from a LinkedIn profile through the Chrome extension.

Most outbound teams need more.

Bulk enrichment of Sales Nav exports runs into the credit-charging complaints multiple G2 reviewers still surface, and the Free plan does not expose the bulk workflow.

There is no way to describe an ICP in plain English and get a list back. And Prospeo does not send email, so the list still has to be handed to another tool for outreach.

For any of those needs, Leadsforge is the routed alternative.

Waterfall enrichment cascades across providers per lookup for higher coverage than a single source. Five event-based Signals paths (Hiring, Job Change, Acquisition, Funding, Investor) return per-match evidence for intent-based outbound. Chat-based ICP search skips Sales Navigator entirely. Every list passes to Salesforge (separate subscription, one login) without a second credential.

Start with 100 free credits at Leadsforge, no credit card required.

FAQs

1. Is Prospeo worth it in 2026?

Yes, for teams that want a data layer rather than a full outreach platform. Prospeo finds and verifies contacts at $0.012 to $0.025 per verified email, does not charge for misses, and exposes the workflow through an API. In a 30-day test it returned roughly 8 in 10 Nordic mid-market emails with bounces close to zero, though it is not worth it if you expected the tool to also send email.

2. How much does Prospeo actually cost per verified contact?

Between roughly $0.012 and $0.025 per verified email depending on plan and billing cycle. Pro billed yearly works out around $0.012, Starter billed monthly around $0.025, and top-up packs are $10 per 1,000 credits. Mobile numbers cost 10 credits, so roughly ten times those figures.

3. Does Prospeo have a free plan?

Yes, with no time limit. The Free plan gives you 100 credits per month, 28 search filters, AI Search, Personas, and the Chrome extension. It does not include API access or CSV enrichment, so it is a good way to test data quality and a poor way to test the workflow the API enables.

4. Does Prospeo charge credits for contacts it cannot find?

No, per Prospeo's pricing FAQ: exports cost 1 credit per email found and 0 credits when no email is found, and the bulk API returns a total_cost alongside separate matched and not_matched lists so you can verify the charge against the results on every call. Multiple G2 reviewers have reported the opposite behavior on bulk imports historically, so re-verify against current docs before committing a high-volume workflow.

5. Can you use Prospeo entirely through the API without the web app?

Yes, on any paid plan. Search, enrich single records, bulk enrich up to 50 at a time, and pull account usage all through the REST API with an X-KEY header, and an MCP server is available if you want an AI agent calling the API directly. API access is not available on the Free plan.

6. What is the best Prospeo alternative for describing an ICP in plain English?

Leadsforge. Chat-based ICP search rather than filter stacking, waterfall enrichment across multiple providers rather than a single source, and one-click export into Salesforge sequences rather than a CSV between tools. $49/month (billed annually) with 100 free credits on signup, no credit card required.

7. When is Prospeo the wrong choice?

When you want one tool that both builds the list and sends to it, when usage is spiky enough that expiring credits become a real cost, or when the target market is one where coverage runs thin. Test on 200 accounts in your actual segment before committing to a plan.

8. Does Prospeo do cold email sending or sequencing?

No. Prospeo has no sending, sequencing, warmup, or inbox. It integrates with sending tools including Salesforge, Outreach, Instantly, Lemlist, Salesloft, and Smartlead, and with Clay and Zapier for workflow orchestration, so it hands contacts to a sending platform rather than replaces one.
