I have a habit of forgetting things. Especially big things. The kind of things that you’d think should be hard to forget. Like nine-figure funding rounds. But that, kids, is why I write things down. So when Panthalassa raised $140 million today, it got me thinking — how does that actually stack up against the largest rounds I’ve covered on Silicon Florist over the years…?
Time for a stroll down memory lane. (For my benefit as much as yours, frankly. Because I could definitely use a refresher.) Here are the biggest Oregon rounds I’ve covered, ranked by amount:
- Vacasa $319M (Oct 2019)
- Agility Robotics $150M Series B (Apr 2022)
- Panthalassa $140M Series B (May 2026)
- Vacasa $103.5M Series B (Oct 2017)
- Hydrolix $80M (Apr 2025)
- SheerID $64M (Nov 2019)
- Eclypsium $45M Series C (Jan 2025)
- Act-On $42M (Apr 2014)
- Puppet Labs $40M (Jun 2014)
- Boulder Care $36M Series B (Jun 2022)
