Stealth AI Startup

Founding Full Stack Developer

Stealth AI Startup
Lithuania · Full-time · Mid-Senior

We’re building the next foundational AI B2B company for the supply chain, distribution, and operations space.


If you’ve ever said:

“I could’ve built that – I just needed the right team.”

This is that moment. Let’s talk.


The founding team so far:


  • CTO – built and scaled one of the fastest-growing tech startups in Europe. Successful exit.


  • CEO – operator who's been there and done that. Founded and led a company to €15M+ in revenue on international scale.


  • COO – Builder, scaling revenue and infrastructure in data and ops-heavy environments. Founded and lead a successful deep-data company.


We’ve done it before. And now we’re doing it again – faster, smarter, and in a $100B+ space.


What we're building:


We’re building AI-native infrastructure for distributors and manufacturers. Our goal is to create a modern AI-powered layer for B2B workflows - automating quoting, ordering, sales and decision support across the stack.


Think AI tooling, not just features – built for depth, scale, and real operational impact.

The space is huge. The incumbents are slow. And the opportunity is wide open.
