Heard from the operators.

"

"Cohort intake used to take two operations people for three weeks. With AccelOS we ran our last cohort with one person in four days — same number of applications, better shortlist."

Erik Hagen
Program Director, Investinor Accelerator
"

"The AI scoring isn’t a magic answer — it’s a second reader. It flags things our partners would catch on their best day, on every application. We spend our review time on the top 10% instead of all 800."
