The outsourced finance and accounting team your investors expect, without the full-time headcount.

CONTROLLERSHIP IN THE AGE OF AI

AI can post a transaction. It can’t protect your business.

Automation has made bookkeeping faster and cheaper than ever. But speed without oversight just means mistakes compound quicker. The real risk for a growing company isn’t data entry, it’s the judgment layer above it: controls, accuracy, and someone accountable for what the numbers actually mean.

That’s controllership, and it’s where we lead. We pair modern accounting tech with experienced controllers who own the close, catch what the software misses, and make sure your reporting is something you and your board can trust.

01

Owned Monthly Close

A controller accountable for accuracy, not just an automated feed.

02

Real Internal Controls

Approval flows and spend controls that scale as headcount grows.

03

Tech, Vetted by Humans

We select, test, and integrate the right tools, then watch them.

04

Numbers You Can Defend

Reporting that holds up in a board meeting or a diligence room.

WHO WE SERVE

Built for the companies under the most financial pressure to get it right.

We focus where stakes and scrutiny are highest, then bring the structure, reporting, and leadership to match.

Venture-Backed Startups

You’ve raised, the board expects more, and basic bookkeeping no longer cuts it. We bring the structure, forecasting, and investor-ready reporting that fast growth and outside capital demand, so you can fundraise and scale with confidence.

EOS®

Finance that runs on Traction

Aligned to the tools your leadership team already uses.

EOS®-ALIGNED FRACTIONAL SUPPORT

Your numbers should drive the same disciplined rhythm as the rest of your business.

Companies running on the Entrepreneurial Operating System® already have a cadence: a Scorecard, quarterly Rocks, and weekly Level 10 meetings. Too often the finance function sits outside that rhythm. We bring it inside, so financial data shows up where your leadership team is already making decisions.

  • Scorecard-ready metrics

  • Numbers ready for L10s

  • Financial Rocks support

  • Visionary & Integrator alignment
