We deploy both hardware and software products to support people on the front lines that span collection, planning / assessments, and effects.

We've grown from $3M in run-rate revenue in 2021 to $80M in run-rate revenue today. We've been profitable since 2022 and have raised $91M in venture capital funding through Series B. We're valued at $1.5B as of 2025.
