Perplexity employee who worked on Comet launches an AI browser aimed at knowledge work

Polar raised a $5.7 million seed round led by Madrona to build an AI-first browser for workplace automation.

Founded by a former Perplexity Comet employee, the startup is targeting knowledge-work tasks rather than mass-market browsing.

The move highlights a shift in AI browsers from chat and search toward agentic tools that can handle real work inside the browser.

Investors see browser agents as a likely next battleground for productivity software and browser adoption.
