Kyle Lubieniecki is a product leader, designer, and builder.
I help early-stage teams find product-market fit, build better products, and put AI to work.
I’ve spent the past decade building and launching B2B products across fintech, edtech, and platforms. Now I run Fractions Studio and build my own projects.

Working together
Justin Shum

“What I appreciate most is how quickly and thoughtfully he translates new customer discovery into actionable product improvements.”

“He quickly delivered a working prototype that we're now using with real customers. He brought the perfect balance of strategic thinking and hands-on execution, exactly what early-stage startups need.”
On building with AI3 testimonials
Product Manager
“Kyle was so kind and had the patience to help me debug setup issues. He also explained concepts to me with clarity prior to diving into the actual mechanics of it.”
Senior Product Manager
Meta
“There's a lot of content out there about specific parts of vibe coding but nothing end-to-end. Kyle's able to tie it all together, which is immensely valuable and saves a lot of time vs. doing it yourself.”
Senior Product Manager
Yara International
“Kyle went beyond vibe coding into practical application. He helped me set up a proper dev environment and ship production-ready code using AI tools. As a PM with limited coding experience, his structured approach made complex concepts accessible and actionable.”
Advising & investing
I advise early-stage teams on product, growth, and applied AI — and I'm starting to back founders with early checks.
