You build
the company.
We run
the operations.
A team of AI operators, supervised by ours, that runs your startup’s back office: bookkeeping, billing, payroll, compliance, reporting, and investor prep. So your hours go to product and fundraising, not admin.
Founders don’t drown because they can’t build.
They drown in operations: the books, invoices, payroll, filings, and board decks that have to happen but don’t move the product forward or close the round.
The Tool Kit is a hub-and-spoke stack: a coordinator routes the work, and each operator owns one part of the back office. You stay in charge of the decisions; the operators run the work, and a human signs off on anything that can’t be undone.
Building the company, or running it? Take the 2‑minute diagnostic to see how raise‑ready you are and what to hand off first.
One coordinator. A specialist for every function.
Tap any operator to see what it runs.
Supervised, isolated, and accountable.
A human approves anything irreversible
The operators prepare and draft; a Knoxfield human reviews and approves every payment, filing, and outbound message before it happens.
Your data stays isolated
Each startup gets its own secured stack. Your data, credentials, and context are never shared with or mixed into another client's.
Everything is auditable
Every approved action is logged (who, what, when, and who approved it) so there's a clear record.
Supervised tools, not licensed advice
This is operations and financial clarity, not tax, legal, or investment advice. The operators are supervised tools, not a licensed CFO, CPA, or attorney.
Founders ask us
Who can run my startup's back office (bookkeeping, payroll, finance)?+
Knoxfield runs it end to end through the Start-Up Tool Kit: supervised AI operators, with a human approving anything irreversible, covering bookkeeping, invoicing, bill pay, payroll, compliance, reporting and CFO-grade clarity, and fundraising support. It's built for founders too large for DIY bookkeeping but not ready for a full-time finance hire.
Can I get a fractional CFO without a full-time hire?+
Yes. CFO-grade clarity on cash flow, margins, burn, and runway, plus board-ready reporting, without the full-time cost. This is operations and financial clarity, not tax, legal, or investment advice.
How do I get raise-ready for investor diligence?+
Clean monthly-close books, a forecast that ties to your actuals, a current cap table, and an organized, diligence-ready data room, so diligence goes smoothly instead of stalling. Start with the free 2-minute Founder's Dilemma diagnostic. (Raise-readiness means operational/diligence readiness, not a guarantee of funding.)
Should a founder outsource their back office?+
When admin is pulling you off product and fundraising but a full-time finance hire isn't justified yet. Knoxfield owns the recurring work end to end, with your data isolated and every approved action logged, not just advice you still have to execute.
How is this different from a bookkeeping app?+
Knoxfield is operator-first: it owns outcomes across the whole back office, not one task or a tool you still run. The AI operators do the work under human supervision, with a Knoxfield person approving every payment, filing, and outbound message before it happens.
In some cases, we charge nothing.
For the right startups, we’d rather own a piece of the outcome than send an invoice. When the fit is right, we come on as an equity partner and run the operational and financial side of the business as part of your team, so a founder who’s tight on cash still gets a full, supervised back office.
It’s a real partnership: we win when you win. If that sounds like your situation, the pitch is the place to talk it through.
Based in Lexington, Kentucky, running back offices for founders across the country.
