About

Meet Devashish Jaiswal.

The technical partner founders and business owners trust to tell them the truth, make the right calls, and build what actually matters.

Devashish Jaiswal, Fractional CTO & AI Architect

“Most people will tell you what you want to hear. I’ll tell you what’s worth building, and then I build it.”

I’m Devashish Jaiswal. I’ve architected real-time voice AI, turned running businesses into live AI dashboards, led a twelve-person team as CTO, and taken a startup all the way to a clean acquisition. I’ve lived the full arc of building technology, from the first line of code to the signed deal.

But here’s the thing: most of the people I help aren’t technical. They’re founders and business owners who need a trustworthy expert to tell them what to build, whether it’s worth it, if their team is on the right track, and where AI genuinely fits, in plain language, with no hype.

I don’t just advise from the sidelines. I roll up my sleeves: shaping the architecture, setting the roadmap, mentoring the team, and making the hard calls. Think of me as the technical co-founder you can plug in exactly when you need one.
