Fractional controller for early-stage tech
I’m Josh Baker. I own the close, reporting, cash forecast, and finance systems for pre-seed through Series B teams.
Nearly a decade inside Shipt and Flatfile.

Built from experience
At Flatfile, I brought accounting in-house and supported a $50 million Series B. At Shipt, I helped scale the accounting function through the Target acquisition.

How it works
From the first call to the monthly close.
01
Intro call
A free, 30-minute conversation about your company, what’s getting in the way, and whether I can help. No prep required.
02
Your first month
I review the books, systems, and reporting, agree on priorities with you, and establish the close plan and responsibilities.
03
Monthly close and reporting
I run the close, deliver reporting, and review it with you on an agreed schedule. I stay available for questions between meetings.
Who I work with
A good fit
- Pre-seed through Series B technology companies
- Founder-led teams without a full-time controller
- Books, reporting, or systems that need a clear owner
- Teams willing to improve the finance stack
Better served elsewhere
- Daily on-site accounting
- Standalone transaction entry
- Inventory-heavy or highly specialized accounting
- Audit or attest work
Let’s talk about what you need.
Thirty minutes, no prep, and no deck required.
