Case study
Keep Financial closes an oversubscribed seed round led by a16z
Keep Financial went from a thesis to a fully defensible capital plan. Tim built a single financial model rigorous enough to support both an equity raise and a debt facility conversation — simultaneously, with sophisticated investors on each side stress-testing the numbers.

Monthly vs. quarterly CFO engagement — which is right for my payments company?
Monthly engagement is right for payments and fintech companies actively deploying capital – growing their team, expanding services, and managing burn. Our CFOs are in the room with your team and have the full context. Precise cadence of the engagement is determined at the initial scoping call.
Quarterly engagement fits payments companies earlier in their journey when their needs are moderately complex, or when they run stable operations that need strategic oversight, board support, and financial review without the ongoing cadence.
The deciding factors are velocity of decisions and complexity of your payment flows. If your GPV, take rate, or burn is moving month to month, monthly coverage pays for itself.
How does Bridges support a financial audit for payments and fintech companies?
The Bridges accounting team gets your books audit-ready before the auditor arrives. For payments and fintech companies, that means clean revenue recognition — platform fees, interchange, and passthrough costs properly separated; clearing accounts reconciled, AR and liabilities current; and all financial processes documented, with sound financial controls established.
We coordinate directly with your external auditor, provide the supporting schedules they need, and resolve any open items.
How does Bridges help payments and fintech companies raise capital?
We ensure your financials are accurate and current, build a detailed model with defensible assumptions and scenarios, craft the narrative, prepare and manage the data room.
Having sat in the investor seat, we know how to translate your payment economics into language venture and private equity investors understand, and make sure your financials can withstand diligence.
We've supported raises from seed through Series B and know what sophisticated investors stress-test at each stage.
How does Bridges help payments companies structure and close a debt facility?
We build the model lenders actually underwrite against. For payments and fintech companies, that means advance rates tied to GPV, repayment coverage under stress scenarios, and clear separation of gross and net revenue so there's no ambiguity in the facility terms. We prepare the financial package, coordinate the diligence process, and stay involved through negotiation.
Equity investors and credit investors ask different questions — we make sure the same model answers both without contradiction.
What happens when we outgrow the engagement — or need to scale back?
Payments and fintech companies scaling fast can increase coverage — more FP&A work, more CFO time, full diligence support — without renegotiating from scratch.
Companies that close a round and want to bring finance in-house get a structured handoff: we help you hire, document the model and processes, and stay available in an advisory capacity during the transition.
Every engagement adjusts with 30 days' notice, in either direction. No long-term contracts, no penalties.
