The intelligence layer

Not a lead list. A precision model.

We catalog 486 tools with 451 priced. We detect 130,000+ replacement opportunities — companies with identifiable tool overlap, known pricing, and a cheaper viable consolidation path. 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. SS OS trains on your wins — fit scores get sharper every time you close a deal.

How it works

Three steps. One compounding moat.

No migration. No rip-and-replace.

1. 1

   Enrich

   Connect any source — Apollo, Clay, your CRM, or the API. Every lead gets stack intel and a verified email added before it hits your pipeline.

2. 2

   Score

   Every lead gets a 0–100 fit score against your ICP — not a benchmark. Score includes the angle that opens the door.

3. 3

   Train

   Mark who converts. The model retrains on your outcomes monthly — and gets sharper for your specific buyers over time.

The team

Your AI agents run the motion. Included in every plan.

Included AI agents handle stack detection, ICP scoring, buyer-model training, and opener drafting automatically — no extra subscriptions. They share one brain: 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

  Every lead that flows through SS OS — from Apollo, your CRM, a CSV, or the open API — trains your buyer model on the full lead record: company size, industry, title, seniority, location, tech stack, funding stage, growth signals, and your conversion outcomes. Not just the intelligence we add. Everything. Month 6, your model knows exactly who converts for you, in your market, at your price point.

• 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.

Recommended integrations

The stack that wires StackSwap OS together.

StackSwap OS runs on your own API keys and connects to the tools you already own. The two highlighted below are our recommended partners — we use them ourselves and think they’re the best fit for most teams running this motion.

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" }

Wire it in

SS OS sits in the middle. Any lead gen in, enriched lead out.

It’s an enrichment and training layer — not a destination. Whatever feeds it, every lead that flows through gets the intelligence layer added and trains your buyer model before it hits your pipeline.

Plug SS OS into the tools your team already uses.

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?

  It reads a company's real stack, scores how well each lead fits your ICP, and trains a buyer-scoring model on your actual conversion outcomes — using the full lead record, not just the stack signals it adds. Month 1: standard fit scores. As your outcomes accumulate, the model retrains on your real conversions — not category averages — so fit scoring should keep getting more accurate for your specific ICP. Month 6: the model is bespoke to your conversion patterns.

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

  Both — the two routes. Sourcing: pick a signal (a tool, category, size, or spend tier) and it surfaces matching companies from 12M+ tracked, pulls the buying committee, and routes them into your CRM. Enrichment: bring a CRM segment or CSV and it adds the stack-intel layer, then writes it back or exports it. Pushes and pulls with HubSpot, Salesforce, Pipedrive, Attio, Close, and Zoho.

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

  Only on a validated match — a no-match is always free. "Validated" means the email is deliverable (NeverBounce single, MillionVerifier bulk) and the company is confirmed running the tool you set. You pay at the tier it validates into: top-tier stack intel is 3 credits, stack-aware is 2, a raw validated contact is 1, no-match is 0. You never pay for a bounce or a phantom contact.

• Do I need to be technical?

  No. Plug in your keys, pick your targets, and your AI agents do the work.

• Is my data private?

  Yes. It runs on your own AI keys — your leads, emails, and customer data stay on your side. Your leads and the model you train are yours: never sold, never handed to a sales team, never used to target your accounts. The only thing we keep is anonymized, aggregated patterns for reporting.

• 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 credits. Two plans — Starter $49 and Max $79 — both include the whole product; the plan sets your credit rate. A raw lead 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). No per-seat tax, no refunds, and credits never expire while subscribed.

• When can I get it?

  Closed sandbox beta starts July 1, 2026. Early access is via waitlist — beta users start training their buyer model before launch, so their model is months ahead of new customers when it goes live. Pricing will be announced at launch.
