Don't Lose Your Series A in Due Diligence | Series A CFO UK
Cost of waiting • Series A miss

The cost of not hiring a CFO.
And what it’s quietly costing you right now.

Most SaaS founders raising Series A in the next 3–9 months discover the price of a missing CFO at the worst possible moment — mid-raise, mid-board-meeting, or mid-runway. Here’s the real cost, and the answer that takes two weeks to put in place.

Hidden costs

Four expensive blind spots SaaS founders raising Series A in the next 3–9 monthsface every month.

Each of these costs more than a year of fractional CFO fees. Most founders don’t see them until it’s too late.

Round priced low — 20–40% discount

Without a CFO triangulating valuation, you accept the first term sheet — usually below market.

Diligence death spiral — 8 weeks added

Financial Q&A management eats founder time, slows the round, gives investors leverage.

Bad term-sheet traps — 20% extra dilution

Liquidation preferences, ratchets and option-pool top-ups the lawyers don’t catch on commercial terms.

Round pulled — 9-month delay

Three IC rejections from spreadsheet-grade modelling = quietly killed round, 9 months to retry.

FAQ

Questions founders ask.

When should I engage a Series A CFO?

3–6 months pre-raise ideally. Pre-raise readiness work — model, data room, KPI baseline, narrative — compounds.

Do you negotiate the term sheet directly?

We review and brief. Your lawyer drafts and negotiates. We focus on commercial economics (pref, pool, ratchets); you and your lawyer drive.

What’s the typical fee for a Series A engagement?

£7.5k–£8k/mo, typically 12–18 weeks. Or fixed-fee £65k–£120k for the whole engagement.

Will you be on every investor call?

Every financial call. Yes.

Can you handle US-based investors?

Yes — ~40% of rounds we’ve supported have US-led terms. Fluent in US comparables, ARR multiples, SAFE mechanics.
