Christian Vismara - Fractional CTO & AI Builder

I build AI products and lead engineering teams for startups that can't afford to get the tech wrong.

I was the first engineer at Chatterbox, where I built the entire platform from zero, led the technology through a £1.5M seed round, and stayed through a B2C-to-B2B pivot that landed BNP Paribas, Microsoft, and McKinsey as clients.

Now I run Digital Kitchen, an AI product studio. We've shipped 10+ products in the last year: WhatsApp bots for coaches, AI website analysis tools, agentic marketing systems, personalized song generators. Real products, real users, real revenue.

I also take on fractional CTO work. Rebuilt an outsourced SaaS platform from the ground up for a German design agency. Shipped a mobile app at NTT DATA that took the App Store rating from 3.0 to 4.5. Led the full technical build of an AI-powered health app (iOS + Android) as fractional CTO.

Based in NYC. MSc in Computer Science from Politecnico di Milano. 11+ years in the industry.

What I do: AI product development, technical leadership for early-stage startups, architecture reviews, MVP builds, and helping non-technical founders figure out what to build and how to build it.
