One Team, One Unified View

Most startups patch together a bookkeeper, a tax firm, a fractional CFO, and an HR consultant who each see their slice and never talk to each other. airCFO replaces all of it with one integrated team.


So when your headcount plan affects your burn, your burn affects your fundraise, and your entity structure affects your tax exposure, someone is always connecting the dots and using that full picture to keep you ahead of what's coming.

The Flightplan Framework

A back office built for your growth, at every stage.

Most finance teams are built reactively, hired when things break, patched when audits loom. airCFO's Flightplan framework is a proactive, stage-matched system that evolves as you raise. Click your stage to explore what's waiting for you.

“Without airCFO, we would have had a lot of difficulties in scaling up as our business became more complex. airCFO was able to grow alongside us and deliver on its value proposition consistently.”
John Kobs
CEO and Co-Founder, Apartment List
Read the Success Story
“At the beginning of a startup and for a very long time, if there's a lot of work but not enough to hire a full-time finance person, it usually falls on the CEO to do that work. By using a fractional finance service, specifically airCFO, I was able to free a lot of mental space to go focus on growing the team and product.”
