Designed & Engineered in SF & Prague

Built by the people
who ran the teams.

A multiple-time CTO who built the Seznam.cz browser, and the director of engineering behind Kiwi.com’s platform. Both kept rebuilding this in spreadsheets until they built it properly.

Jirka Bachel

Co-Founder & CTO of Onetone.ai · Built the Seznam.cz browser, 1.5M monthly users

18+ years of technical leadership across Silicon Valley and Prague. Multiple-time CTO, most recently co-founder and CTO of Onetone.ai, where AI read every customer support interaction. Before that he built the Seznam.cz browser, used by 1.5M people a month. He managed engineering orgs for years and answered “are we on track?” with gut feeling and quarterly retros.

I managed teams for 18 years on gut feeling. There is a better way to manage AI-native teams.

Peter Malina

Director of Engineering at Kiwi.com · ran the platform behind it

15+ years leading engineering teams. Most recently, Director of Engineering at Kiwi.com, where he ran the Platform group. A decade scaling teams and infrastructure for consumer products with millions of users, and a decade explaining that work to people who never opened a pull request.

The hardest part was never the technology. It was showing the business what engineering had actually done.
