Constantin Botnari - fractional CFO for UK SaaS founders.
CIMA-qualified fractional CFO working with UK SaaS, AI and tech founders running £500k-£15M revenue companies. I built the reporting platform you've just been clicking through - it's the same tool every client uses inside their engagement with me. Not a separate SaaS product. Not licensed to outsiders. Just the way I run finance for founders who don't have a CFO yet.
Why "ongoing support" instead of days-per-week? Startups don't operate in five neat days. They have an investor call on a Wednesday morning and a re-forecast deadline by Friday. Clients get direct calendar access for strategic calls, board-meeting prep, fundraising decisions, and the "quick question about month-end" that turns into 40 minutes. Engagements are month-to-month - no minimum contract. Several have now run 3+ years because the work keeps working, not because anyone is locked in.
What changes when a founder gets a CFO and a real reporting platform.
Three engagement patterns. Anonymised by request - happy to walk through real names on a call.
Outcomes shown are illustrative of comparable engagements. Specific results depend on company stage, data quality and execution.
Reporting tool, fractional CFO, or both?

What happens on the discovery call.
30 minutes. No pitch. You leave with a clearer view of your finance picture - whether or not we end up working together.
We look at your current numbers.
You share a P&L, a budget, or read-only Xero access. Constantin reads what's there and flags the obvious things - revenue recognition, margin shape, where cash is hiding.
What your board pack would look like.
Walkthrough of the platform with realistic placeholder figures for your stage. Dashboard, MRR schedule, scenarios, forecast. You see exactly what the board sees.
Honest answer - is it a fit?
If yes, what month 1 looks like, pricing, timeline. If no, who else to talk to. Either way you leave with two or three things to fix in your finance setup this week.
Pick a time. Cancel any time. UK-based, available across UK business hours.

A SaaS board pack is the monthly or quarterly report a company sends to its board of directors and investors. It typically includes: ARR and MRR with growth deltas; the MRR movement waterfall (new, expansion, contraction, churn); 3-way financials (P&L, balance sheet, cash flow); cash runway and burn; unit economics (NRR, GRR, CAC payback, LTV:CAC); pipeline and sales-target attainment; customer cohorts; a hiring plan; and the CEO's narrative covering wins, watch items, and asks of the board. A typical investor-ready board pack for a UK SaaS company is 15-25 pages.
UK fractional CFOs typically charge £3,000-£8,000 per month depending on company stage, engagement scope, and whether reporting tooling is included. ScaleWithCFO engagements start at £3,000/month and include the board pack platform, monthly close support, strategic calls, pre-board review, and ongoing CFO availability via direct calendar access. Month-to-month, no minimum contract. No day-rate counting - ongoing support, the way founders actually work.
A reporting tool alone (Causal, Cube, Abacum, Mosaic) gives you a model and dashboards but no human to interpret the numbers, build the investor narrative, or sit with you before the board meeting. A fractional CFO alone gives you the human, but often relies on spreadsheets that drift out of sync. ScaleWithCFO combines both: a 3-way reporting platform plus ongoing CFO support - pre-board review, investor narrative, fundraising prep, and strategic calls when you need them.
Constantin Botnari is a CIMA-qualified fractional CFO and the founder of ScaleWithCFO. He works with UK SaaS, AI and tech founders running companies with £500k-£15M revenue. He built ScaleWithCFO's 3-way reporting platform - the same tool every client uses inside their engagement. Several of his founder engagements have run 3+ years.
UK SaaS, AI and tech founders running companies with £500k-£15M annual revenue. Typical clients are post-revenue but pre-finance-hire - too big for an accountant alone, too small to justify a full-time CFO. Many are preparing for a Series A or B round, planning a strategic exit, or scaling past £1M ARR and needing investor-grade reporting.
First board pack typically takes 3-6 weeks from kickoff: week 1 is Xero connection, account mapping, and a clean-up pass on the chart of accounts; weeks 2-3 build the 3-way model and assumptions; week 4 is the first dry-run board pack with you; weeks 5-6 produce the first board-ready pack for distribution.
A 3-way financial model links the profit & loss, balance sheet, and cash flow into one model that always reconciles. Every assumption - sales targets, hiring, working capital, fundraising - flows through all three statements automatically. Cash is the balancing item on the balance sheet. The cash flow statement is derived from balance sheet movements, so by construction the model never 'breaks.' This is the standard format UK investors and lenders expect.
Yes. One-click Xero OAuth pulls in the trial balance, P&L and balance sheet by month. Account mappings are reviewed with you and locked, so monthly closes are repeatable. QuickBooks is supported. Stripe and HubSpot sync are available for revenue and pipeline data.
You can - most founders start there. The problem is version control, broken formula links, manual reconciliation between P&L and cash flow, and the 8+ hours of prep before each board meeting. ScaleWithCFO removes those tax steps: actuals stream in from Xero, the model recalculates on every assumption change, and the board pack regenerates as a versioned PDF in two clicks.
A fractional CFO is not a replacement for your accountant - it is a complement. Your accountant handles statutory accounts, VAT and Companies House. The CFO sits inside the business: monthly close, board pack, forecasting, fundraising support, scenario modelling, and the strategic finance conversations the board expects. ScaleWithCFO works alongside your existing accountant.
