AiSDR vs Amplemarket: Which AI SDR Is Better?

If you're weighing AiSDR vs Amplemarket, you're choosing between an AI that works alone and an AI that helps your reps work faster. I priced one job on all three tools: reaching about 2,000 new prospects a month by email and LinkedIn. Every price here comes from each vendor's live pricing page on October 7, 2026.

AiSDR is an AI SDR agent that researches leads and contacts them by email, LinkedIn, and phone steps. Amplemarket is an all-in-one sales platform with a B2B database, a dialer, and an AI copilot called Duo. Agent Frank is the autonomous AI SDR that runs on Salesforge's Forge Stack.

On that job, AiSDR's Scale plan costs $2,500/mo on a quarterly contract. Agent Frank plus 20 Megaforge mailboxes costs about $668/mo billed quarterly, or $568/mo billed annually.

AI SDR Comparison at a Glance: AiSDR vs Amplemarket

AiSDR Overview: Ami, Plans, and Limits

AiSDR is an AI SDR agent that finds prospects across the web, researches them, and contacts them by email, LinkedIn, and phone. Its homepage says it puts lead quality over volume, and its pricing page says 250+ companies use it.

When I checked on October 7, 2026, its live stats panel showed 1,019 meetings booked and $127.2M in influenced pipeline over the past 30 days.

Core features

• Ami AI: a go-to-market (GTM) strategist agent that suggests campaign ideas, reviews results, and builds campaigns in one click.
• AI research: emails and LinkedIn actions are researched and sent on autopilot, with unlimited AI personas.
• LinkedIn: connection requests, direct messages, and InMail on every plan.
• Calls: AI call steps through an Aircall dialer, with call scripts and follow-ups.
• Replies: the AI answers in 5-10 minutes, or runs in co-pilot mode.
• Email setup: domains, mailboxes, and warm-up are set up for you.
• Signals: LinkedIn engagement and profile visits from Explore up, plus website visitor tracking on Scale.
• CRM: native two-way HubSpot sync on every plan, and Salesforce sync only on Scale.

Pricing

AiSDR lists three public plans, and annual billing saves 20%. Explore and Scale need a quarterly contract paid in advance.

• Solo: $250/mo month-to-month, or $2,400/yr ($200/mo). 200 AI-researched contacts a month, 1 user, 1 domain, 3 mailboxes, and 1 LinkedIn account.
• Explore: $900/mo, or $8,640/yr ($720/mo). 800 contacts a month, unlimited users, 2 domains, 6 mailboxes, and 5 LinkedIn accounts.
• Scale: $2,500/mo, or $24,000/yr ($2,000/mo). 2,500 contacts a month, 6 domains, 18 mailboxes, and 20 LinkedIn accounts.

A managed service costs extra: $149 per campaign on Explore, or $2,500/mo on Scale. CostBench's August 25, 2026 snapshot and Hackceleration's pricing check list the same three prices.

Who AiSDR is best for

AiSDR fits founders and small HubSpot teams that want to test AI outbound month to month. Solo is the only plan you can start without a sales call.

Limitations and what reviewers say

• Volume gets pricey. Solo works out to $1.25 per researched contact and Scale to $1.00.
• Sender caps are tight. Solo includes 3 mailboxes and 1 LinkedIn account, and Scale stops at 18 and 20.
• Integrations are limited. G2's summary of 89 reviews praises AiSDR's support, but notes some users want more integration options.
• Value is its weak spot in testing. Hackceleration's 2026 review scores AiSDR 3.7/5 overall and 2.5/5 on value for money, where it says AiSDR loses the most ground.

AiSDR has no Trustpilot reviews yet, so these points come from G2 and Hackceleration. This AiSDR reviews breakdown and the Agent Frank vs AiSDR page go deeper.

Amplemarket Overview: Duo Copilot, Plans, and Limits

Amplemarket is an all-in-one sales platform that pairs a B2B contact database with sequences, a dialer, and deliverability tools. Its AI layer, Duo, spots buying signals and drafts outreach, and a rep approves it before it sends.

Its homepage pitches "Human + AI" and calls Duo an AI sales copilot. So it makes reps faster rather than working as an SDR on its own.

Core features

• Duo Copilot: daily signals, account research, and drafted sequences. Amplemarket says it saves reps 10+ hours a week.
• Duo Signals: buying intent such as website visits, job changes, and competitor activity.
• Contact and company search: a B2B database with email and phone credits, including 200M verified mobile numbers.
• Sequences and dialer: email, calls, and social steps such as connection requests, with an outbound dialer on every plan.
• Duo Voice and Duo Inbox: AI voice messages from Amplemarket Growth up, and auto-drafted replies on Elite.
• Deliverability: Deliverability Booster warm-up and a Domain Health Center on every plan.
• MCP and AI Agents: prospect and research from Claude or ChatGPT, plus agents that find buyers and personalize outreach.

Pricing

Amplemarket shows one public price, for Startup on an annual term. It says all plans include a free trial.

• Startup: $600/mo on an annual term ($7,200/yr). 2 users, 27,000 contacts, 13,500 email and 600 phone credits per user a year, and 2 mailboxes per user.
• Amplemarket Growth: custom quote. 4 users, 140,000 contacts, a dedicated customer success manager (CSM), and Duo Voice.
• Elite: custom quote. 10 users, 400,000 contacts, Duo Inbox, and SSO.

Each plan lets you buy more users on top. Pricing breakdowns from Hackceleration and MarketBetter confirm the $600 Startup price and say every plan is annual-only.

Who Amplemarket is best for

Amplemarket fits sales teams with several reps who want data, a dialer, and an AI copilot in one annual contract. It suits call-heavy teams, since the dialer comes on every plan.

Limitations and what reviewers say

• A person still approves. Duo drafts the outreach for a rep to review, so rep time stays part of the cost.
• Annual term only. The $7,200 first year is the floor, and larger plans need a sales call.
• No automatic reply drafts on Startup. Duo Inbox is included on Elite and sold as an add-on on Amplemarket Growth.
• Data quality draws complaints. One Software Advice reviewer wrote "Bad data quality, cannot rely on the database," and SaaSworthy's review summary lists occasional data inaccuracies.

Amplemarket has no Trustpilot reviews either, and G2 still rates it 4.6/5, per Prospeo's 2026 breakdown. This Amplemarket review sums up 100+ user reviews, and Salesforge vs Amplemarket compares the two platforms.

Agent Frank Overview: The Autonomous AI SDR on the Forge Stack

Agent Frank is Salesforge's autonomous AI SDR. He finds prospects, checks their data, writes personalized emails and LinkedIn messages, follows up, handles replies, and books meetings, 24/7.

He runs inside a free Salesforge workspace and uses the whole Forge Stack. Salesforge also says he works next to your sales team, not instead of it. This AI SDR vs SDR guide compares the two roles.

Core features

• Prospecting from Leadsforge: he searches 500M+ B2B contacts in Leadsforge, around the clock.
• Enrichment first: contact and company data are enriched and verified before any message goes out.
• Auto-Pilot or Co-Pilot: let him run on his own, or have him draft every message for your approval.
• Multichannel sequences: email and LinkedIn touches share one sequence, and follow-ups branch on what each prospect does.
• AI personalization across 21+ languages: he pulls from each prospect's website, blog posts, and LinkedIn posts, in 9 tones.
• Knowledge Base: upload brochures, docs, and your website, and he treats them as his source of truth.
• Meeting booking: he books meetings on your calendar. You choose his goal: send your meeting link, ask for the prospect's, or drive a click.
• Unlimited senders: no cap on mailboxes or LinkedIn senders.
• Replies in Primebox™: every email and LinkedIn reply lands in one inbox, tagged by sentiment.
• Deliverability: Warmforge warms every mailbox for free, and Megaforge spreads sending across Gmail, Outlook, Mailforge, and Infraforge mailboxes.
• A human in the loop: every customer gets a dedicated Account Manager and a shared Slack channel.

This Salesforge tutorial walks through Frank's setup and a live campaign.

The Forge Stack behind him

Agent Frank is the top layer of the Forge Stack. Under one roof sit infrastructure (Mailforge, Infraforge, Primeforge), deliverability (Warmforge), a lead finder (Leadsforge), multichannel outreach (Salesforge), and Frank himself. Leadsforge lists flow straight into his sequences, with no CSV export.

All three infrastructure options run under one login, so you can switch as volume grows without migrating. Every Forge product is MCP-native, so Claude, Cursor, or your own agents can run it too.

The same stack runs three ways: your own team, Agent Frank, or a vetted Forge Expert agency.

Pricing

Agent Frank costs $599/mo billed quarterly, or $499/mo billed annually with 2 months free. That covers 1,000 Active Contacts, which Salesforge says reaches 2,000+ new contacts a month, or $0.25 per contact on annual billing.

More volume moves you up a tier: 2,000 Active Contacts cost $1,138/mo billed quarterly ($948/mo annually). Mailboxes are extra: bring your own, use Infraforge, or add Megaforge from $69/mo for 20 mailboxes.

Frank is a separate subscription from Salesforge's own plans. If your team also runs outreach by hand, Salesforge Pro is $48/mo monthly ($40/mo annual) and Salesforge Growth is $96/mo monthly ($80/mo annual), with a 14-day free trial (verify the live price).

Who Agent Frank is best for

Salesforge says its stack fits B2B companies with $5K-$100K ACVs that sell to startups, SMBs, or mid-market buyers and target 3,000+ businesses.

It also says who it doesn't fit: teams that mainly target Fortune 500 companies, run long RFP cycles, or close six- and seven-figure deals.

Proof and honest limits

In the VAI Consulting case study, Agent Frank booked 3 calls within the first week after a pivot to a tighter ideal customer profile (ICP). Positive reply rates also jumped.

• No free trial. You book a demo first, and a dedicated Account Manager helps with each setup step.
• A 2-week warm-up comes before his first send, handled free by Warmforge.
• Mailboxes cost extra, from $69/mo for 20 on Megaforge.

Head-to-Head Feature Comparison: AiSDR vs Amplemarket

Here's how all three handle the eight jobs an AI SDR has to do.

Multichannel outreach: email, LinkedIn, and phone

AiSDR: runs email, LinkedIn connection requests, DMs, and InMail, plus AI call steps through Aircall. LinkedIn accounts are capped at 1 on Solo, 5 on Explore, and 20 on Scale.

Amplemarket: mixes email, dialer calls, and social steps such as connection requests in one sequence. AI voice messages need Amplemarket Growth or Elite.

Agent Frank: runs email and LinkedIn in one sequence, and follow-ups branch on whether a prospect accepts, replies, or goes quiet. Senders are unlimited, so a tenth LinkedIn profile costs nothing extra.

For call-heavy outbound, Amplemarket has the edge. Its dialer and mobile credits come on every plan, while Agent Frank works only by email and LinkedIn.

Email deliverability and warm-up

AiSDR: sets up domains, mailboxes, and warm-up for you. Its pricing page says several inboxes need 30+ days to get ready, one reason Explore and Scale use quarterly contracts.

Amplemarket: includes Deliverability Booster warm-up and a Domain Health Center on every plan. Its spam checker and mailbox recommendations start on Amplemarket Growth.

Agent Frank: every mailbox warms in Warmforge's premium pool of aged IMAP/SMTP, Google Workspace, and Microsoft 365 mailboxes, with a Heat Score™ for each. Megaforge splits 20 mailboxes across four providers, so if one provider blocks sending, the rest keep going.

AI personalization and autonomy

AiSDR: finds leads in real time across the web, researches each one, and writes with unlimited AI personas. Ami suggests campaigns and builds them in one click, and Scale adds AI videos and LinkedIn voice notes.

Amplemarket: Duo learns your company from your website and CRM, drafts each sequence, and improves from your feedback. A rep approves before anything sends.

Agent Frank: personalizes from each prospect's website, blog, and LinkedIn posts in 21+ languages and 9 tones. On Auto-Pilot he sends and replies alone; on Co-Pilot he waits for your OK.

On rich media alone, AiSDR Scale goes further, with AI video and voice notes built in.

Lead data and buying signals

AiSDR: finds people in real time across the web and works with your own lists from Explore up. It tracks LinkedIn engagement on Explore and website visitors on Scale.

Amplemarket: Duo Signals watch website visits, job changes, and competitor activity, and the database includes 200M verified mobile numbers. A Software Advice reviewer still questioned its data quality.

Agent Frank: prospects from 500M+ Leadsforge contacts with waterfall enrichment. Leadsforge can also build lists from intent signals such as funding rounds, job changes, and tech stack shifts.

This guide to B2B buying signals explains what they are and how outbound teams use them.

Reply handling and inbox

AiSDR: answers replies within 5-10 minutes on its own, or runs in co-pilot mode.

Amplemarket: Duo Inbox auto-drafts replies to prospect emails, but only on Elite, or as an add-on on Amplemarket Growth. Startup doesn't include it.

Agent Frank: every email and LinkedIn reply lands in Primebox™ with a positive, neutral, or negative tag. He answers on Auto-Pilot, drafts on Co-Pilot, or leaves the thread for a human. Primebox™ also catches replies sent from a different address than the one Frank emailed, and it runs on mobile.

Pricing and scalability

AiSDR: charges per researched contact, about $1.25 each on Solo and $1.00 on Scale. More volume means a bigger plan and a quarterly contract.

Amplemarket: charges for seats and data credits on annual terms. Startup includes 2 users and 600 phone credits per user a year, so more reps or more calling mean more seats or a custom plan.

Agent Frank: charges per Active Contact, and 1,000 of them reach 2,000+ new contacts a month for $599/mo billed quarterly ($499 annually). Senders stay unlimited, so adding LinkedIn profiles or mailboxes doesn't raise his price.

Integrations, API, and MCP

AiSDR: native two-way HubSpot sync on every plan, Salesforce sync only on Scale, and Aircall for calls.

Amplemarket: integrations and an MCP server for Claude or ChatGPT on every plan. CRM base filters start on Amplemarket Growth, and SSO is Elite-only.

Agent Frank: works inside Salesforge, which connects natively to HubSpot, Salesforce, Pipedrive, Attio, GoHighLevel, folk, Breakcold, and Clay, plus Zapier, Make, and webhooks. The full integrations library and the API need Salesforge Growth, while the MCP server and Forge CLI let AI agents run the whole stack.

Onboarding, support, and security

AiSDR: Solo is self-serve with email and chat support. Explore and Scale add a GTM engineer for onboarding and 24/7 Slack support, and Explore includes a monthly check-in and webinar.

Amplemarket: Startup gets community onboarding and a scaled CSM team, and a dedicated CSM starts on Amplemarket Growth. Email support and a help center come on every plan.

Agent Frank: every customer gets a dedicated Account Manager and a shared Slack channel. The Account Manager helps build his Knowledge Base, set up mailboxes, and launch after the 2-week warm-up. Salesforge is SOC2 compliant.

AI SDR Pricing Comparison: What 2,000 New Leads a Month Costs

Every price below comes from each vendor's live pricing page on October 7, 2026.

AiSDR's bill grows with researched contacts, and both plans above Solo need a quarterly contract. Amplemarket's bill grows with seats and data credits on an annual term. Agent Frank's bill grows with Active Contacts while senders stay unlimited.

Annual billing helps each tool differently. AiSDR takes 20% off, Agent Frank gives 2 months free, and Amplemarket has no monthly option to save against.

Scenario: about 2,000 new prospects a month

• Agent Frank: $599/mo billed quarterly plus $69/mo for 20 Megaforge mailboxes, about $668/mo. Billed annually, Frank drops to $499/mo, so the pair runs about $568/mo.
• AiSDR: Explore's 800 contacts won't cover it, so you need Scale at $2,500/mo, or $2,000/mo billed annually. That's $24,000-$30,000 a year.
• Amplemarket: Startup's 2 users get 27,000 email credits a year, about 2,250 a month, for $600/mo. But Duo drafts, your two reps approve, and automatic reply drafts aren't included.

On this job, AiSDR Scale costs about 3.5 to 3.7 times what Agent Frank and Megaforge cost on the same billing terms. Amplemarket is close on software price, but it buys a copilot for two reps, not an SDR that works alone.

Agent Frank vs AiSDR vs Amplemarket: Which AI SDR Should You Choose?

The real question is who does the work: an AI on its own, or your reps with AI help. Salesforge also keeps more AI SDR comparisons if you're weighing other tools.

You might consider AiSDR if:

• You're a founder or solo seller who wants to test AI outbound for $250/mo with no contract.
• You run HubSpot and want AI video and voice notes in outreach, which come on Scale.
• You'd like AiSDR's team to run campaigns for you, from $149 per campaign.

You might consider Amplemarket if:

• You have several reps and want a database, a dialer, and an AI copilot in one annual contract.
• Calls drive your pipeline. For call-heavy teams it's the better fit, since the dialer and mobile credits come on every plan.
• You want a rep to approve every message before it goes out.

Choose Agent Frank if:

• You sell B2B at $5K-$100K ACVs to startups, SMBs, or mid-market companies and target 3,000+ accounts.
• You want email and LinkedIn run for you on Auto-Pilot or Co-Pilot, with no limit on senders.
• You need 2,000+ new contacts a month for $599/mo billed quarterly ($499 annually), not $2,500 on AiSDR Scale.
• You want deliverability handled: free Warmforge warm-up, Heat Score™ tracking, and multi-ESP Megaforge mailboxes.
• You want options: your team, Agent Frank, or a Forge Expert agency can run the same stack.

Final Verdict: The Best AI SDR for SMB and Mid-Market Outbound

AiSDR and Amplemarket solve different problems. AiSDR does the SDR work itself, but it charges about $1 per researched contact and caps senders on every plan. Amplemarket gives reps data, a dialer, and an AI copilot, but a rep still approves the drafts on an annual contract.

For SMB and mid-market teams that want email and LinkedIn outbound run for them, Agent Frank is the stronger choice. He reaches 2,000+ new contacts a month from $499/mo billed annually ($599/mo quarterly), with unlimited senders, free Warmforge warm-up, and Primebox™ for every reply.

Here's what Salesforge can be held to. The same 2,000-contact month costs about $668 with Agent Frank and Megaforge billed quarterly, against $2,500 on AiSDR Scale. And in the public VAI Consulting case study, Frank booked 3 calls in the first week after an ICP pivot.

If you sell mostly to Fortune 500 accounts through long RFP cycles, Salesforge itself says it isn't the right fit. For everyone else selling B2B at $5K-$100K ACVs, Agent Frank is my pick.
