ClosWitWe Exist To Be The Technical Co-Founder Every Founder Deserves
ClosWit was built on a simple belief — a great idea shouldn't fail just because its founder isn't technical.
ClosWit is a team of engineers, designers, and product strategists who partner with founders to turn ideas into real, working startups. We're not a typical agency — we act as your technical co-founder, invested in the outcome, not just the invoice.
From validation to MVP to scaling, every engagement follows the same principle — transparent pricing, weekly communication, and decisions made with your long-term success in mind.
Julian Roth
Founder & CEO, ClosWit
“I started ClosWit because I watched too many great founders get taken advantage of by agencies that treated their startup like just another invoice.”
Before ClosWit, I spent years building products for other people's startups — and saw the same pattern over and over. Founders with brilliant ideas, stuck choosing between developers who didn't understand their business and agencies more interested in billable hours than outcomes.
ClosWit exists to be the technical co-founder I wish every one of those founders had. That means transparent pricing, honest timelines, and a team that treats your roadmap like our own equity depends on it — because we genuinely believe it should.
If you're a founder with an idea, I'd love to hear what you're building. That first conversation costs nothing, and it might be the one that gets your startup off the ground.
