Soultab is built by a solo founder who got tired of watching SaaS teams spend money driving traffic to pages that strangers didn't understand.
The curse of knowledge is undefeated. Every founder ships a landing page that makes perfect sense to them — and everyone who could warn them already works at the same company. Soultab exists to be the outside view: five synthetic evaluators who approach your site the way real strangers do, file receipts on what didn't land, and hand you the evidence before you spend a dollar on ads.
The engine is real and running. Personas navigate live SaaS sites in real browsers. Every finding carries a chain of custody — the exact prompt version, model, and browser context that produced it. The eval infrastructure behind it (reference cohorts, test-retest gates, persona differentiation metrics) is the kind of rigor that would be unreasonable for a product this early — except we think a truth-telling instrument should hold itself to a higher standard than the sites it evaluates.
Soultab is in early access. The founder personally runs every scan and sends the report. No signup, no card, no bots crawling without permission. If that sounds like a lot of manual work — it is, and it's exactly how we want to calibrate the instrument.
