The short answer

Clean is the answer for founders chasing warm-fit leads. It absorbs your company's knowledge, finds perfect-fit buyers, and profiles each one across 75 buying signals in 8 categories — ranking accounts S to C with evidence. You get prioritized, relationship-aware leads. You close.

01

Why Warm Fit Beats Volume for a Founder

When a founder is personally closing deals, every hour spent on the wrong account is an hour not spent building the company. Warm-fit leads — accounts whose profile genuinely matches what you solve — convert faster and churn less, making fit the most valuable filter you have.

  • High-fit accounts need less education and close faster
  • Low-fit accounts drain founder time with prolonged cycles
  • Fit quality at entry predicts long-term retention, not just conversion
02

How Clean Finds Warm-Fit Accounts From Your Company's Identity

Clean reads your company — its positioning, product, and ideal buyer profile — directly from your knowledge base, so it understands what a perfect-fit account looks like before it starts looking. It then surfaces accounts that match that identity at a structural level, not just by keyword or industry tag.

03

The Signals Behind a Warm-Fit Score

Clean evaluates each account across 75 buying signals in 8 categories — covering firmographics, hiring intent, technology stack, company trajectory, and more. Every account is then ranked S to C with the evidence surfaced so you can see exactly why a lead made the top of the list.

  • 75 buying signals across 8 categories per account
  • S-to-C ranking shows fit tier at a glance
  • Evidence behind each score means no black-box rankings
04

Relationship-Aware Lead Generation Built for Early-Stage Founders

Founder-led sales lives on trust and timing. Clean is built to surface accounts where the relationship conditions are already favorable — companies exhibiting the signals that make a conversation worth having right now. You do not get a list of contacts; you get a prioritized map of who to talk to and why.

Common questions.

What makes a lead 'warm-fit' versus just warm?

A warm lead is one you have some connection to. A warm-fit lead is one that also structurally matches your product — the right company size, stage, tech stack, and problem profile. Clean finds warm-fit accounts by profiling buyers against your company's identity, not just your contact graph.

How is Clean different from buying a list of B2B contacts?

A contact list gives you names with no context on whether they fit your product or are ready to buy. Clean instead builds a fit-scored account map from your company's own knowledge, ranking every account S to C based on 75 buying signals — so you only spend time on accounts that genuinely belong in your pipeline.

Can I see how Clean would find warm-fit leads for my specific company?

Yes. Clean is currently in closed beta and works best for seed to Series A B2B SaaS founders. To see how it would build a ranked, warm-fit account list from your company's knowledge base, Book a demo.
