About Ivan Burazin
Ivan Burazin is co-founder and CEO of Daytona, which Slush describes as agent cloud infrastructure for enterprises and AI labs. His own bio says Daytona is an open-source platform for secure runtime environments for AI coding agents. He co-founded it in 2023. Crunchbase lists him in New York.
Before Daytona he co-founded Codeanywhere, an early cloud IDE. Company and speaker bios date its start to 2009, while Crunchbase lists him as founder and CEO from 2013 to 2021. He also founded Shift, a developer conference in Southeast Europe. Infobip acquired Shift in 2021.
After the acquisition he served on Infobip's executive board and as Chief Developer Experience Officer until 2023, when he left to start Daytona. Tracxn lists Daytona's co-founders as Burazin, Vedran Jukic and Goran Draganic, and reports $79.3M raised across four rounds.
Burazin is listed in an angel directory for developer tools started by swyx. Its entry gives his focus as the AI Enablement Stack. Crunchbase shows one personal investment, in Lightsage.
On X he has described writing a small angel check into a seed round. He said the company later raised again and passed a $100M run rate. He did not name the company in the post. No public fund or syndicate is attached to his angel activity.
Lounge's deals desk lists two AI rounds. The first is Lightsage's $4M seed round in September 2026. Press coverage says Nexus Venture Partners led it. Lightsage builds tools to help software products reach and be used by AI agents. The company named Burazin among its operator investors.
The second is Strix's $6.7M seed round in June 2026. Strix is an open-source AI security platform that uses autonomous agents to pentest applications, APIs and codebases. Crunchbase lists Heavybit as lead investor. I found no public source describing Burazin's check in Strix.
His directory entry says he backs startups in the AI Enablement Stack, from devtools to middleware to agents themselves. The same entry gives his check size as $1 to $10k. That is the only check size figure I found, and it comes from his own listing. His known deals are seed rounds. I found no stated geographic focus.
- Lightsage: tools for agent-led software adoption; seed round of $4M announced September 2026, led by Nexus Venture Partners.
- Strix: open-source AI security platform that pentests with autonomous agents; $6.7M seed round, June 2026.
