OpenFunnel
Headless API primitives that let your coding agents find, research, and sync GTM leads into Salesforce or HubSpot.
OpenFunnel is the rare lead-gen tool that assumes you write code. If your GTM motion already runs through Claude Code, Codex, or Cursor, the 50,000 free credits make testing nearly free, and the TAM builder plus Salesforce/HubSpot sync with deduplication remove a lot of manual data entry. The July 2026 OpenBenchmarks launch signals the company is betting on agents as the buyer, which is coherent with the API-only design. It is not a Clay or Apollo replacement for non-coders — there is no point-and-click interface on the free tier, and enrichment is a paid add-on. Buy it for programmable workflows, not for a UI.

Skip OpenFunnel if you need a clickable outbound tool your SDRs can run without code — the free tier is APIs only, and the full UI sits on the Enterprise/Custom plan alongside a Forward Deployed Engineer.
Work-email and phone-number enrichment sit outside the free tier as separately paid add-ons, so per-credit cost climbs once you need contact data.
OpenFunnel's DIY tier is free with 50,000 credits and no credit card, which undercuts Clay and Apollo for teams happy to work through APIs. That makes it a natural fit for seed-to-Series-B GTM engineers who already pay for a coding assistant. Once you need the full UI, a dedicated Forward Deployed Engineer, on-prem deployment, or verified enrichment, pricing moves to a custom enterprise plan — the same budget bracket as enterprise Clay or Apollo seats, but spent on primitives rather than seats.
In short
OpenFunnel — Headless API primitives that let your coding agents find, research, and sync GTM leads into Salesforce or HubSpot. Best for GTM engineers building custom AI agents for lead generation, RevOps teams automating TAM expansion and account research, Startups using Claude Code, Codex, or Cursor to generate leads at scale. Free to use.

About OpenFunnel
OpenFunnel is a headless, API-first platform that gives engineering and RevOps teams the primitives to build custom go-to-market agents rather than clicking through a sales tool. You call its endpoints to run lookalike search against closed-won, closed-lost, and seed accounts, describe an ICP to build a full TAM in one call, search companies by the tools and vendors they run (with an optional buying-intent filter), and deep-research a single account against a custom qualification question. Its hiring primitives find companies hiring for a specific role, for a named internal initiative, mentioning a pain point in job posts, or making that hire for the first time; separate hiring-trend primitives catch companies scaling or accelerating an initiative across multiple posts. Social signals cover companies and people posting about your space on LinkedIn and X, and LinkedIn engagement primitives surface ICPs already warmed up by competitor reps. CRM hygiene is first-class: account and contact sync into Salesforce and HubSpot with deduplication plus a job-status polling endpoint. Because everything is consumed through APIs, OpenFunnel suits teams that build with Claude Code, Codex, or Cursor. It is backed by Y Combinator, and in July 2026 it launched OpenBenchmarks, an API discovery tool that helps agents find and select the right SaaS APIs for GTM automation. Start on the free DIY tier with 50,000 credits and no credit card, or move to a custom plan for dedicated support and on-prem deployment.
Behind the Verdict
OpenFunnel's pitch is unusually specific: it is not a sales tool with an AI feature bolted on, it is a set of GTM primitives that only make sense because your agent is the one calling them. The primitive list is genuinely broad for an early-stage product — lookalike search, company-description search, a TAM builder, tech-stack search with a buying-intent filter, deep account research, five hiring-initiative primitives, four hiring-trend primitives, four people-hired-and-moved primitives, social signals on LinkedIn and X, LinkedIn engagement for competitor-warmed ICPs, and account plus contact sync into Salesforce and HubSpot with deduplication and job-status polling. That is a lot of surface area for a tool you can try with 50,000 free credits and no credit card. The honest trade-offs: the free DIY tier ships standard rate limits, work-email and phone-number enrichment are add-ons paid separately, and there is no point-and-click GUI on DIY — the full OpenFunnel UI only appears on the Enterprise/Custom plan, which pairs it with a Forward Deployed Engineer, managed or hosted workflows, and custom-instance or on-prem deployment. So the realistic split is: developers and GTM engineers who live in coding assistants get a cheap, composable data layer; non-technical SDR teams get nothing they can click. Against Clay or Apollo, OpenFunnel is the more programmable and lower-cost option for the data-and-sync slice, but it deliberately does not try to be a full sales engagement platform. The July 2026 OpenBenchmarks launch is the most interesting signal about direction — an API discovery tool for agents suggests OpenFunnel expects the buying agent, not the human, to be picking vendors. If that framing matches how your team builds, this is worth prototyping; if you need a UI-first workflow or conversational features, look elsewhere.

Real-world workflow fit
Concrete scenarios for the personas OpenFunnel actually fits — and what changes day-one when you adopt it.
They define their ICP in a prompt inside Claude Code, call the TAM builder to generate the full addressable market, then run lookalike search against their closed-won list to rank the highest-resemblance accounts.
Outcome: A ranked account list in code within the free 50,000-credit tier, with no manual spreadsheet research.
They schedule the CRM account sync and CRM contact sync primitives so matched domains and contacts flow into Salesforce with deduplication, polling the sync job status endpoint to confirm completion.
Outcome: Salesforce stays current without reps pasting records in, and duplicate accounts stop accumulating.
They run the hiring-initiative primitives on job posts to find companies hiring for a named initiative, then layer social signals on LinkedIn and X plus LinkedIn engagement for ICPs warmed by competitor reps.
Outcome: A shortlist of accounts showing active intent signals, ready for outreach while the hiring post is still fresh.
Use Cases
- Build your full TAM from an ICP definition with a single API call
- Find companies hiring for a specific role to target active buyers
- Detect companies scaling hiring for a concept across multiple job posts
- Deep-research one account against custom qualification questions
- Sync matched accounts and contacts into Salesforce or HubSpot with deduplication
- Monitor LinkedIn and X for companies and people posting about your space
- Source ICPs already engaged by competitor reps on LinkedIn
- Find people recently hired to lead an initiative or who changed jobs
Models Under the Hood

Limitations
- OpenFunnel is API-first and built for coding agents, so the free DIY tier gives you primitives rather than a point-and-click interface — non-technical users will need real coding skills or a Forward Deployed Engineer.
- Work-email and phone-number enrichment are treated as add-ons rather than included features, so per-credit costs can rise.
- The DIY plan runs on standard rate limits, which can throttle heavy usage.
- The full OpenFunnel UI and managed integrations (Salesforce, HubSpot, Slack, Clay, and others) only come with the Enterprise/Custom plan.

DIY
$0/mo
Ideal for
Developers and GTM engineers using Claude Code, Codex, or Cursor who want to prototype agent-driven lead gen without a sales call.
What this tier adds
Free entry point: 50,000 credits, all agent-ready primitives, deploy-your-own signal agents, and standard rate limits — no credit card.
Enterprise / Custom
Custom
Ideal for
Teams running GTM at scale that need the graphical UI, managed workflows, verified enrichment, or on-prem deployment.
What this tier adds
Adds custom credit pools, a Forward Deployed Engineer, managed/hosted workflows, custom-instance or on-prem deployment, the full OpenFunnel UI, verified enrichment, and managed integrations.
Where the pricing makes sense
The company stage and team size where OpenFunnel's pricing actually pencils out — and where peers do it cheaper.
OpenFunnel's DIY tier is free with 50,000 credits and no credit card, which undercuts Clay and Apollo for teams happy to work through APIs. That makes it a natural fit for seed-to-Series-B GTM engineers who already pay for a coding assistant. Once you need the full UI, a dedicated Forward Deployed Engineer, on-prem deployment, or verified enrichment, pricing moves to a custom enterprise plan — the same budget bracket as enterprise Clay or Apollo seats, but spent on primitives rather than seats.
Setup time & first value
How long it actually takes to get something useful out of OpenFunnel — broken out by persona, not the marketing-page minute.
For a developer already working in Claude Code, Codex, or Cursor: minutes to sign up for the free DIY tier (no credit card) and make the first TAM builder or lookalike call. Building a scheduled pipeline that syncs into Salesforce or HubSpot: a day or two to handle auth, deduplication behavior, and job-status polling. Non-technical teams should expect weeks unless they buy the Enterprise/Custom
Switching to or from OpenFunnel
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Clay: move the data-enrichment and account-research steps to OpenFunnel primitives and keep Clay for the manual table work it still does better.
- →From Apollo: replace contact search with lookalike and tech-stack search, then sync matched accounts to your CRM instead of exporting CSVs.
- →From manual sales research: encode your ICP as a TAM builder call and let hiring and social-signal primitives replace the weekly spreadsheet pass.
- →From Zapier-style CRM glue: swap the zaps for the native Salesforce and HubSpot sync primitives with deduplication and job-status polling.
- ↗To Clay: export matched accounts and rebuild enrichment as Clay tables if you need a visual workflow for non-coders.
- ↗To Apollo: move contact sourcing and sequencing into Apollo if you want an all-in-one outbound platform rather than primitives.
- ↗To in-house scraping plus your own enrichment vendor: keep the OpenFunnel signal logic but swap the data layer if per-credit add-on costs outgrow your budget.
