Find the accounts running a stack you can beat. Pay only when the lead validates.

Two routes, one engine

Bring a signal, or bring your list.

Same intelligence engine, two ways to point it. Pick the one that matches the motion you’re running — and in both, you only pay for leads that validate.

Sourcing fills the top of the funnel; enrichment sharpens the pipeline you already have. One engine, billed only on validated matches.

The intelligence layer

Not a lead list. A precision model.

We catalog 486 tools with 451 priced. We detect 130,000+ companies actively overpaying — the exact displacement angles you can win on, with known spend bleeding. We map 370,000+ company tech stacks. We cover 12M+ companies total. The question is not how many leads but how many precision targets.

Two plays, near-zero dead leads

Every account is winnable — one of two ways.

The engine tags every company it reads. When it detects a tool you can beat, you get the kill shot. When it doesn’t, it falls back to a play that still earns a reply. Either way, the lead isn’t dead.

The ceiling play when there’s blood in the water. The floor play when there isn’t. Together: a queue with almost no dead leads in it.

The old way vs StackSwap OS

Generic lead scoring. Or a model built on your data.

Every enrichment vendor sells the same scores to every customer. StackSwap OS is different: it starts with the same raw intelligence, then trains a buyer model on your actual conversion outcomes — so the fit scores improve every time you close a deal.

How it works

Turnkey to start. Smarter every month.

No migration project, no rip-and-replace. Three steps to a buyer-scoring model that compounds on your own data.

1. 1

   Connect your data sources

   Wire in Clay, PDL, or your CRM — or push leads straight in through the open API. Wherever your lead data lives, your team of AI agents starts reading stacks and building your enriched ICP list.

2. 2

   Score your ICP

   Feed it companies — or let it find them — and the engine returns a ranked queue with a fit score (0–100) for each: how well they match your ICP, why, and what angle gives you the best shot.

3. 3

   Tag outcomes and train

   Mark who converted, who replied, who went dark. The model retrains on your outcome data each month — and becomes progressively more accurate for your specific ICP. Month 6 looks nothing like month 1.

The team

You’re the operator. This is your team of AI agents — included in every plan.

Four AI agents, included in every plan, each owning a slice of the motion. The sandbox beta runs the loop that makes the model yours — the GTM Stack Expert (reads stacks, scores your ICP) and the Buyer-Model Scientist (tags outcomes, retrains your model). The GTM Engineer wires it up; the Pipeline Strategist comes online across the cohorts.

They share one brain. The Stack Expert’s read feeds the fit-scoring model; the Buyer-Model Scientist’s training sharpens it; the Pipeline Strategist turns the scores into the next move. One database, one context — experts that hand work to each other, not four subscriptions pretending to be a team. And the buyer model they train is yours, not ours.

What’s inside

The beta starts with the scoring loop.

One hosted app that reads stacks, scores leads against your ICP, and trains a buyer model you keep — on your own AI keys. The sandbox beta ships the two surfaces marked Live; the wider cockpit rolls in across the cohorts.

• 01Live in beta

  Lead intelligence + fit scoring

  Reads a company's real stack from job posts and signal data, infers monthly spend, and scores how well they fit your specific ICP — not a generic benchmark. Each score includes the why: what makes this a now-buy, what angle to open with.

• 02Live in beta

  Your data, your model

  Runs on your own AI keys, so your scored leads, outcome data, and trained buyer model stay on your side — nothing routes through us. The model improves with every conversion you tag. One subscription, and you keep what it learns.

• 03Rolling in

  The revenue cockpit

  Trial → activated → paid, MRR, churn risk, and the next play to run, in one view. It syncs your CRM; it doesn't replace it.

• 04Rolling in

  Demand capture

  Scored buying-intent signals, plus the names of companies quietly checking out your site — so you can reach them first.

• 05Rolling in

  One pane for visibility

  SEO audits + Search Console, GA4 analytics, and ad spend — under the same roof, instead of a row of separate dashboards.

• 06Live in beta

  Buyer persona export

  Export your trained buyer model anytime — JSON persona you own outright. It travels with you. The model only keeps compounding while you're pulling leads through StackSwap OS, but the snapshot is always yours. No hostage data.

Why precision is the product

Every lead pulled makes the model sharper.

API + Headless

Hook it to your AI agent. Use it headless.

Every route in the SS OS dashboard is available via REST API. Your Claude project, your Codex pipeline, your custom enrichment workflow — pass a domain or company, get back the stack signal, fit score, and drafted opener. Credits pull from your account exactly as they do in the UI. Every API pull trains your buyer model too.

POST /api/enrich
Authorization: Bearer <your-api-key>

{ "domain": "northwind.io" }

Pricing

A flat base, plus credits for what you enrich.

Two plans — Starter $49/mo, Max $79/mo — both with the whole product. The plan just sets your credit rate. Then you top up credits as you enrich: 1 credit for a raw lead, 2 for full stack and spend intelligence. No per-seat tax, no refunds, and credits never expire while you’re subscribed.

Questions

The honest FAQ

• What does StackSwap OS actually do?

  StackSwap OS is a lead intelligence and proprietary buyer-model training system. It reads a company's real stack — primarily from job posts and signal data — scores how well each lead fits your specific ICP, and builds a buyer-scoring model trained on your actual conversion outcomes. Month 1: standard fit scores. Month 3: the model retrains on your data and becomes 15–25% more accurate. Month 6: your model is bespoke to your conversion patterns. Month 12: switching cost is nearly infinite, because you've built something no one else has.

• Can it source net-new leads, or only enrich my list?

  Both — they are the two routes. Intelligence sourcing: you pick a signal (a tool, a category, a company size, a spend tier) and StackSwap OS surfaces the matching companies from 12M+ tracked, pulls the seniority-filtered buying committee, and routes them into your CRM. List enrichment: you bring a CRM segment or a CSV and it adds the stack-intel layer — detected stack, recoverable spend, displacement angle, fit band — then writes it back or exports it. It pushes and pulls with HubSpot, Salesforce, Pipedrive, Attio, Close, and Zoho, or you export a CSV.

• When am I charged a credit, and what does "validated" mean?

  You are charged only on a validated match, and a no-match is always free. "Validated" means two things are true before a credit moves: the email is deliverable, and the company is confirmed running the tool you set. StackSwap OS verifies deliverability at pull time — NeverBounce for single leads, MillionVerifier for bulk — a layer that the underlying data sources do not provide. A lead is billed at the tier it actually validates into: top-tier stack intel (named displacement angle, buyer-model fit 75+, verified contact) is 3 credits, stack-aware is 2, a raw validated contact is 1, and a company we scan and return nothing on is 0. You never pay for a bounce or a phantom contact.

• Do I need to be technical?

  No. You connect your accounts and your team of AI agents runs it for you. Plug in your keys, pick your targets, and the agents do the work.

• Is my data private?

  Yes. It runs on your own AI keys, so your leads, emails, and customer data stay on your side — nothing is resold, and nothing routes through us.

• Will it replace my CRM?

  No. It syncs your CRM; it doesn't replace it. Keep the system of record you already trust.

• What if I want to switch a vendor later?

  Swap it in a click. Changing your enrichment, sending, or AI provider is a setting — not a rip-out project.

• How does pricing work?

  A flat monthly base plus prepaid enrichment credits. Two plans — Starter $49 and Max $79 — both include the whole product; the plan just sets your credit rate. A raw lead with a verified email is 1 credit; full stack-and-spend intelligence is 2. Credits start at $1 and ladder down in bulk (as low as $0.50 on Max). The buyer model you train on your outcomes is yours to keep. No per-seat tax, no refunds, and credits never expire while you are subscribed. Founders lock 25% off the base for life.

• When can I get it?

  Closed sandbox beta starts July 1, 2026. Beta users start training their buyer model on real ICP data before launch — so by the time the product goes live, their model is already 3 months ahead of new customers. Grab a Founders Club spot now ($99) to get in first.
