“I'm building this because I miss it in the market myself.”
Hi — I'm Richard Bajnath, founder of Kozynofferte. I've watched window installers spend evenings hand-crafting Excel quotes with prices that don't add up and proposals lost in email threads. Kozynofferte is my answer: one workflow, EU-VAT-correct, e-signature and online payments — built with window installers, not for them.
We're in pre-launch with room for ten founding customers. You get 50% off Professional for the first six months, a direct line to me personally, and roadmap influence.
