I'm Vishesh Duggar — 5x founder, 15+ years as a CTO. I take AI systems from impressive demo to running in production. I build my own (Neo), and I work with a small number of clients each quarter.
working EU/UK hours
building for global markets
For funded teams and established businesses whose AI needs to actually ship.
We find the single highest-leverage bottleneck across product, AI, and engineering — and build the action plan to clear it. You leave with a decision, not a deck.
The fee is credited against a build engagement if we continue.
Weekly working sessions, async architecture and code reviews, roadmap ownership. I sit with your team where the decisions actually get made.
As long as it's useful. No lock-in.
I work with a handful of clients per quarter. Reach out early.

“I had the privilege of being hired and working closely with Vishesh during our time at Vamstar. As the CTO, Vishesh consistently demonstrated exceptional leadership, technical expertise, and strategic vision — but also understood where expertise was needed and allowed them to be voiced. His experience in scaling web, mobile, and tech products was a driving force in Vamstar.”
“He is a true powerhouse of ideas and always encourages his team to explore new approaches to a problem. He values the input of every team member and is super involved with every team, creating a truly collaborative atmosphere. One of the hardest working people I have worked with — never afraid to roll up his sleeves and dive into the intricacies of a problem.”
“He is incredibly helpful with every aspect of a product's roadmap, and with his extensive experience in entrepreneurship, Vishesh provides a similar expertise with every aspect of the startup's journey.”
“Vishesh is an excellent strategic thinker and very easy and fun to work with — he cuts into the essence of any problem and is able to suggest clear, detailed, and practical solutions. He was very helpful in informing my app development strategy, suggesting efficient ways to get the app built while balancing a thoughtful, customer-centric experience.”
“Invaluable tips on product/market fit, ideal customer profile, building scalable processes. In one hour I learned things that would have taken me 5 years to learn the hard way.”
“I met Vishesh at a conference, and in one quick chat I learned a lot about ideation and how to think about really good products.”
“He shared strategic, cost-effective marketing strategies that were very helpful. Smart, practical advice.”
“One of the most well accomplished and humble entrepreneurs I know. His advice and recommendations are priceless.”
Neo is a voice-controlled interface for the Mac: Rust, on-device GGUF inference, sub-100ms latency, nothing leaving the machine. Built by me, in production, on the same constraints I'd hold your team to.
65+ episodes, 40K+ monthly views. Long conversations with operators about what actually broke, and what they did about it.
A paragraph is enough: what you're building, where it's stalling, and what shipping would mean. I read and answer these myself.
