Action1

Cloud-native patch management that remediates endpoints without a VPN or on-prem console.

Proof of life. H1 2026 ARR from six-figure deals grew 275% year over year

Action1 is founder-led patch and vulnerability remediation for mixed Windows, Mac, and Linux fleets. Agents check in over the internet, so remote laptops get the same Tuesday patch as the office. No venture round on the cap table, which is rare in this category, and 2026 growth is coming from six-figure enterprise deals rather than a new fundraise.
