Built a tool to find buyers who ACTUALLY buy

When you sell to founders, the hard part isn't finding companies. There are millions of them. The hard part is telling which ones actually spend money on growth, and which are a weekend project with a landing page. So I started from a simple idea: if a company paid for a featured or sponsored spot on a launch directory, it has already shown it will pay a stranger on the internet for distribution. That doesn't mean it'll buy from you, but it's much better evidence than headcount or funding guesses. What I built: BuyerCue A pipeline crawls public SaaS directories and records every paid or featured placement, with the source link and the date it was seen. Each company's own site is enriched with what it does, who it sells to, pricing, the tech stack (including paid tools and ad pixels), and public business contact routes (role emails, contact pages, company socials). Each company gets a buying-signal band (high / moderate / unclear) that's recomputed from the stored evidence. It's a way to prioritize, not a purchase probability. Right now it has about 2,900 companies from six directories, and nearly all of them have direct evidence of paid placement. Things I learned building it Most data on a page doesn't belong to that company. Testimonial logos, demo placeholders, and "hosted by" lines in privacy policies all look like company data. Every field now needs a positive ownership check and a source URL before it gets stored. null beats a guess. An empty price field is fine. A made-up one quietly destroys trust in every other row. No named people. I deliberately skipped personal emails and LinkedIn scraping. The lead is the company plus a public business channel. That's more useful and less creepy. How it works Search and filter everything for free, no account needed. You see the product, audience, evidence summary, and signal band, but the company's identity is masked. When one looks like a fit, you unlock it (one token per company, and it's yours to keep) to see the name, contacts, and full evidence, then export to CSV. There's no subscription. Your first unlock is free when you sign up. Stack, for the curious: TypeScript end to end, Next.js 16, MongoDB, Zod as the single schema source, and standalone Node workers for crawling (never inside request handlers). I'd really like feedback on: Does "paid for a directory listing" make sense to you as a buying signal? What filter would you want first if you were prospecting with this? Link: buyercue.io
