Kakiyo vs Agent Frank: Which Cold Outreach Tool Is Superior?

A founder with a four-person sales team asked me this exact question last month. His LinkedIn motion worked. His email motion kept landing in spam.

He wanted one AI SDR to own both channels instead of two tools that never talk to each other.

That is the real decision here, and these two products answer it differently. Kakiyo is a LinkedIn-native AI SDR that holds the whole conversation inside the DM thread and books meetings off it. Agent Frank is Salesforge's AI SDR who runs email and LinkedIn from one workspace and routes every reply into Primebox™.

I pulled both live pricing pages on 11 August 2026 before writing this. Kakiyo's had changed enough that every third-party source I could find was out of date.

AI SDR Comparison at a Glance: Kakiyo vs Agent Frank

Kakiyo Overview: Features, Pricing, and Limitations

Kakiyo is an AI SDR built for one channel. It connects to a LinkedIn account, sends connection requests, opens the conversation, answers replies, qualifies the prospect, and books the meeting.

Every message is generated from the prospect's profile rather than pulled from a template. Kakiyo benchmarks itself against sequence tools and manual prospecting, not other AI SDRs. A longer Kakiyo review covers the walkthrough.

Core Kakiyo features

• End-to-end LinkedIn conversations - replies, objections, and pricing questions handled in-thread
• In-thread qualification - asks your questions on budget, timeline, and decision process
• Autonomous meeting booking - qualified prospects get times on your calendar
• Three control modes - autopilot, copilot, and manual
• Sandbox testing - challenge the agent with objections before going live
• Account protection by design - local-IP cloud sessions, 2 to 15 minute reply delays, automatic limit management
• Agency white-label - branded dashboard, custom domain, client isolation, no extra cost
• Integrations - CRM, API, and MCP access on every plan

Kakiyo pricing

Kakiyo prices in euros and bills per connected LinkedIn account. Every plan includes every feature, so tiers differ only by account count and seats.

• Kakiyo Pioneer - €125/mo monthly, €113/mo quarterly, €100/mo yearly. One LinkedIn account, one team member, 14 days free
• Kakiyo Hunter - €315/mo monthly, €284/mo quarterly, €252/mo yearly. Up to three LinkedIn accounts, unlimited team members
• Kakiyo Conqueror - €495/mo monthly, €446/mo quarterly, €396/mo yearly. Up to five LinkedIn accounts, unlimited team members
• Agency - 10 or more LinkedIn accounts, white-label dashboard, custom pricing through sales

Who Kakiyo is best for

Kakiyo fits founders and small teams whose pipeline lives on LinkedIn. One to five people sending DMs, with no email motion worth saving, is the shape it targets.

What reviewers say

Kakiyo shows 4.4 out of 5 on Trustpilot from roughly 36 reviews. Most are strong, and the critical ones are specific enough to read before you commit.

Honest Kakiyo limitations

• One channel. There is no email product, so no sequences, no warm-up, no inbox placement tooling, and no infrastructure layer
• Seats gate the price. Kakiyo Pioneer covers one LinkedIn account and one team member, so a second seat means Kakiyo Hunter at €315/mo monthly
• Currency exposure. Pricing is in euros. Dollar-budget teams carry the exchange rate, which sat near 1.155 on 11 August 2026
• Thin public record. 36 Trustpilot reviews is a small sample, and the site advertises a 14-day trial in most places against a 30-day trial on one button

Agent Frank Overview: The AI SDR Inside the Forge Stack

Agent Frank is Salesforge's autonomous AI SDR. He finds prospects, verifies the data, writes the outreach, follows up, handles replies, and books meetings across email and LinkedIn.

Frank also runs inside the Forge Stack. The mailboxes, the warm-up, the lead database, and the inbox are all products Salesforge builds, so you are not bolting separate tools together.

What Agent Frank does

• Multi-channel sequences - email and LinkedIn touchpoints in one workflow, branching on prospect behavior
• Auto-Pilot and Co-Pilot - fully autonomous, or he drafts and a human approves before anything sends
• Continuous prospecting - 24/7 sourcing from the 500M+ contact database behind AI lead search
• Three configurable goals - drive click-outs, send a meeting link, or receive one
• Knowledge Base grounding - upload brochures, docs, and your site so he sells from your source of truth
• Nine tonalities and 21+ languages - from Formal to Playful, matched per campaign
• Personalization sources - the prospect's website, their blog posts, and their LinkedIn activity
• Availability windows - operating hours, days, and time zones you set
• Primebox™ reply handling - email and LinkedIn replies in one inbox with automatic sentiment tagging
• Free unlimited warm-up - premium pool warm-up with a Heat Score™ per mailbox
• Megaforge infrastructure - 20 mailboxes split across Gmail, Outlook, Mailforge, and Infraforge, from $69/mo
• Human support - a dedicated Account Manager and a shared Slack channel

The Forge Stack context

Salesforge sells the layers around Frank as separate products under one login: Mailforge and private email infrastructure for sending, Warmforge for deliverability, Leadsforge for leads, and Salesforge for execution. Each is its own subscription, which is a real cost consideration rather than a hidden one.

Frank is managed from a complimentary Salesforge workspace, so you get the outreach dashboard without paying for a second seat-based tool. The full Forge Stack is documented publicly if you want to price a build.

Agent Frank pricing

Agent Frank is a separate subscription from Salesforge's Pro and Growth plans. He is not bundled into either.

• Agent Frank - $499/mo billed quarterly, or $416/mo billed annually, covering up to 1,000 active contacts
• At 2,000+ contacts a month the rate drops to roughly $0.25 per contact
• Optional email infrastructure add-on through Infraforge or Megaforge, from $69/mo
• For reference, Salesforge's own plans are separate: Pro at $48/mo monthly or $40/mo annual, Growth at $96/mo monthly or $80/mo annual

Who Agent Frank is best for

Salesforge publishes a tight ICP: B2B sellers with ACVs between $5K and $100K, decision-makers at startups through mid-market, and a target list of 3,000 accounts or more.

The published outcomes cover that range. AKOOL reached over 214,000 prospects at a positive reply rate above 16%.

Honest Agent Frank limitations

• Slow to start. There is no free trial, a demo is mandatory before you can buy, and mailboxes then warm for two weeks before Frank sends his first email
• Infrastructure is extra. The $499/mo price does not include mailboxes, and Salesforge says outright that Frank works alongside human reps rather than replacing them
• A published anti-ICP. Salesforge states it is a poor fit for Fortune 500 targets, long RFP cycles, and six- or seven-figure deal sizes

Head-to-Head Feature Comparison: Kakiyo vs Agent Frank

Channel coverage

Kakiyo is LinkedIn only. Agent Frank runs email and LinkedIn inside one conditional sequence, so a prospect who ignores a DM can pick up the email thread instead.

This is the whole comparison for most buyers. If your ICP does not answer LinkedIn DMs, Kakiyo has no second route to them. Salesforge also has phone outreach on its public roadmap.

For how operators pair the two channels, the LinkedIn social selling breakdown is worth reading.

Email deliverability and warm-up

Kakiyo has nothing here, and that is not a criticism of the product. It sells a LinkedIn agent, so deliverability is out of scope by design.

Agent Frank inherits Warmforge free and unlimited with every Salesforge subscription. Warm-up runs in a premium-by-default pool of aged IMAP, Google Workspace, and Microsoft 365 mailboxes, with a Heat Score™ per mailbox where 97 or above counts as healthy.

Salesforge publishes its own thresholds too: keep bounces under 1%, and pause immediately above 5%. If you are auditing an existing setup, the common cold email mistakes list covers the usual causes.

Sender and seat scaling

Kakiyo's tiers are account counts: one LinkedIn account on Pioneer, three on Hunter, five on Conqueror, and a sales conversation above ten. Team seats follow the same ladder, with one member on Pioneer.

Frank works out of a Salesforge workspace where mailboxes are unlimited on every plan, and LinkedIn senders are unlimited on the Growth plan. You add sending capacity without changing what the agent costs, because Frank bills on active contacts instead of seats.

Salesforge publishes the volume maths behind that. Each inbox should send 30 to 50 cold emails a day across 2 to 5 mailboxes per domain, so 1,000 emails a day needs roughly 20 to 30 mailboxes across 5 to 10 domains.

AI writing and personalization

Both generate every message rather than filling a template. Kakiyo writes from the prospect's profile and adapts to what they say back, which reads well in the reviews I checked.

Frank pulls from three sources at once: the prospect's website, their blog posts, and their LinkedIn activity. He is grounded in a Knowledge Base you upload, picks from nine tonalities, and works across 21+ languages. Salesforge also sells Overdrive Mode inside the platform for all-source personalization previews.

Reply handling and inbox

Kakiyo handles replies where they happen, in the LinkedIn thread, with objection handling and qualification built in. For a single channel that is a clean model.

Frank routes everything into Primebox™, which merges email and LinkedIn replies in one inbox, tags each thread positive, neutral, or negative, and catches replies that arrive from a different address than the one you contacted. Primebox is included free with every subscription, and the unified inbox ships on mobile too.

Lead sourcing

Kakiyo finds leads in-app and takes CSV imports, and its plans advertise unlimited real-time lead discovery.

Frank prospects continuously from Leadsforge, which searches 500M+ B2B contacts with waterfall enrichment across 10+ data providers, real-time email validation, and competitor-follower extraction. For manual list building, the LinkedIn prospecting guide walks through the same workflow by hand.

The list quality shows up in results. ChannelCrawler ran Salesforge with Infraforge and Warmforge to an 85.71% positive reply rate.

Account safety and compliance

Kakiyo publishes a detailed LinkedIn safety model: cloud sessions with no browser extension, keyboard and mouse simulation instead of API injection, a local IP from your city, 2 to 15 minute reply delays, and automatic daily limit management. It is the most thorough public write-up of the two on LinkedIn risk specifically, and if LinkedIn account safety is your single biggest worry, that transparency is a fair reason to shortlist it.

Salesforge is SOC 2 compliant, which is the document enterprise procurement asks for. Kakiyo publishes no SOC 2 report that I could find.

Integrations and developer surface

Both offer CRM, API, and MCP access. Kakiyo includes all three on every plan, which is genuinely simpler than gating them.

Salesforge integrates natively with HubSpot, Salesforce, Pipedrive, Attio, and Clay, plus Zapier and webhooks. It also ships an MCP server and a CLI that drives the whole stack from a terminal. API access and the full integrations library sit on the Growth plan.

The sales tools directory lists Frank's features in a shorter format, and Salesforge vs Apollo covers the same ground against an all-in-one platform.

Onboarding and time to first send

Kakiyo is much faster to start. You register, connect LinkedIn, and run, with 14 days free to test it first.

Frank takes longer on purpose. A demo is mandatory, then an Account Manager builds your Knowledge Base and infrastructure, then mailboxes warm for two weeks.

If you need to send this week, that is a real cost. The team wrote up what 20 AI SDR demos looked like in their AI SDR demo roundup.

AI SDR Pricing Comparison: What Each One Actually Costs

These two price on different units, so headline numbers mislead. Kakiyo charges per connected LinkedIn account. Agent Frank charges per active contact.

Kakiyo's euro pricing needs converting before you can compare the two. At the 11 August 2026 rate of about 1.155, Kakiyo Conqueror at €495/mo works out near $572/mo.

A concrete scenario

Say you are three people reaching 2,000 new contacts a month and you want both channels covered.

On Kakiyo you need three LinkedIn accounts, so Kakiyo Hunter at €315/mo monthly, roughly $364. Email is not an option at any price, so you would buy a separate sending platform, mailboxes, and a warm-up tool on top.

On Agent Frank, 2,000 contacts lands near $0.25 per contact, so roughly $500/mo, plus Megaforge from $69/mo for 20 mailboxes. That is about $569/mo with both channels, the infrastructure, and the warm-up already inside the number.

They also scale in opposite directions. Frank gets cheaper per contact as volume rises. Kakiyo gets more expensive per step, because every seat past five moves you into a sales conversation.

Who Should Use Which AI SDR

You might consider Kakiyo if:

• Your pipeline is LinkedIn-only, you have no email motion to save, and LinkedIn account safety is your main worry
• You want to test an AI SDR this week without a sales call, since the 14-day Kakiyo Pioneer trial has no demo gate and Agent Frank has no trial at all
• You run an agency that wants a white-label LinkedIn dashboard included rather than quoted

Choose Agent Frank if:

• You sell B2B with ACVs between $5K and $100K into a list of 3,000+ target accounts, which is the ICP Salesforge publishes
• You need email and LinkedIn in one sequence, with replies landing in one inbox instead of two
• Deliverability is the thing that keeps breaking, and you want warm-up, Heat Score™ monitoring, and mailboxes from the same vendor
• You are scaling past five senders and refuse to pay per seat to do it
• You want a named human on the account, since a dedicated Account Manager and shared Slack channel come with the subscription

One honest exclusion: if you sell to Fortune 500 procurement on long RFP cycles with six-figure deal sizes, Salesforge says on its own site that it is the wrong tool. Neither product on this page fits that motion. If neither shape matches yours, the full comparison library covers the rest of the category.

Final Verdict: Which AI SDR to Choose in 2026

Kakiyo is a well-built agent for one channel. It writes real conversations, handles objections in the thread, and documents its LinkedIn safety model more openly than most.

For B2B teams running real outbound, Agent Frank is the stronger choice, because outbound that depends on a single channel breaks when that channel goes quiet. Frank covers email and LinkedIn, prospects from 500M+ contacts, handles replies in Primebox™, and warms mailboxes free through Warmforge. Kakiyo sells none of that, and at €495/mo its top tier already costs more than Frank's $499 base.

One falsifiable benchmark you can check yourself: VAI Consulting booked three calls in a single week with Agent Frank running the outreach. UniteSync hit an 85.26% positive reply rate at a $2.86 CAC. Both case studies are published with names attached.

If you need to send something tomorrow with no sales call, start on Kakiyo's trial. If you want outbound still running in a year, the demo and two-week warm-up are the cheaper decision.

Frequently Asked Questions About Kakiyo and Agent Frank

Is Agent Frank better than Kakiyo?

For multi-channel B2B outbound, yes. Agent Frank runs email and LinkedIn in one sequence, while Kakiyo works on LinkedIn only. Frank also brings free unlimited Warmforge warm-up, Primebox™ for replies, and four infrastructure options. Kakiyo is the better pick in one narrow case: you want to start today without a sales call, because its Pioneer plan has a 14-day free trial and Agent Frank requires a demo.

What's the main difference between Agent Frank and Kakiyo?

Channel coverage and what sits underneath it. Kakiyo is a LinkedIn-only AI SDR priced per connected LinkedIn account, from €125/mo. Agent Frank works across email and LinkedIn, priced per active contact from $499/mo billed quarterly, with 1,000 active contacts in the base. Kakiyo sells no email product, so there is no warm-up, no inbox placement tooling, and no mailbox infrastructure.

Which is cheaper, Agent Frank or Kakiyo?

Kakiyo is cheaper to start at €125/mo for one LinkedIn account. It stops being cheaper at scale. Kakiyo Conqueror runs €495/mo monthly for five LinkedIn accounts, which is about $572 at the 11 August 2026 rate, more than Agent Frank's $499/mo base. Frank drops to roughly $0.25 per contact above 2,000 contacts a month.

Does Kakiyo support email outreach?

No. Kakiyo is built for LinkedIn conversations only, from connection request through to booked meeting. There is no email sequencing, warm-up, or deliverability tooling in the product. If you want both channels from one agent, Agent Frank handles email and LinkedIn in a single conditional sequence and routes every reply into Primebox™.

Can I switch from Kakiyo to Agent Frank easily?

Yes, though it is a setup rather than a migration. Agent Frank starts with a mandatory demo, then a dedicated Account Manager helps build your Knowledge Base and infrastructure inside a complimentary Salesforge workspace. Budget two weeks for mailbox warm-up before the first email sends. Your LinkedIn motion can keep running while email warms in the background.

Which AI SDR has better email deliverability?

Agent Frank, because Kakiyo has no email product to compare. Frank includes Warmforge free and unlimited, warming in a premium-by-default pool of aged IMAP, Google Workspace, and Microsoft 365 mailboxes, with a Heat Score™ per mailbox where 97 or above is healthy. Megaforge spreads sending across Gmail, Outlook, Mailforge, and Infraforge so one burnt ESP does not stop a campaign.

Does Agent Frank offer a free trial?

No. Agent Frank is only available after a demo with the Salesforge team, and mailboxes then warm for two weeks before he sends. Salesforge itself does offer a 14-day free trial on its Pro and Growth plans, but that covers the platform rather than the AI SDR. Kakiyo, by contrast, offers 14 days free on its Pioneer plan with no demo required.

Who is Kakiyo best for?

Founders, recruiters, and small sales teams whose pipeline genuinely lives on LinkedIn, running one to five seats. Its LinkedIn safety model is unusually well documented: cloud sessions with no Chrome extension, keyboard and mouse simulation, a local IP, and 2 to 15 minute reply delays. Agencies get a white-label dashboard included at no extra cost, with volume pricing above ten accounts.
