Startup Fundraising Brief
Investors decide in the first 90 seconds. Most founders bury their best story under feature lists and £40bn TAM slides. The Startup Fundraising Brief distils messy founder enthusiasm into a one-page narrative — the spine every deck, cold email, and verbal pitch builds on.
What this skill does
The first 90 seconds of any investor encounter are not about the product. They're about whether a stranger can repeat your story back to a partner who wasn't in the room. Most founders fail this test, not because their business is weak but because the narrative is buried — page seven of the deck, paragraph four of the email, minute six of the call. This skill writes the narrative spine and forces it to the front.
The brief is built in a specific order because that order is what hooks investors. Hook (one or two sentences that get the email opened), Problem (specific, quantified, visceral — not "businesses struggle"), Insight (what the team understands that others don't), Solution (what it does, not how it works), Traction (the proof, growth-rate-first because early-stage growth rate matters more than absolute numbers), Market (wedge first, then the staircase), Team (founder-market fit, not LinkedIn-summary), Ask (amount, what it buys, what milestones it unlocks). Same skeleton every time; the emphasis shifts with stage.
It picks one of six narrative frames based on the situation. Timing — something changed, this window. Insight — counterintuitive truth others missed. Momentum — recent launch, impressive numbers, just the beginning. Inevitability — the trend is happening, the question is who captures the value. Pain — specific persona, quantified suffering. Data — for pre-revenue, engagement metrics as proxy for demand. The frame isn't decoration; it's what makes the same set of facts feel investable rather than informational.
Two things the skill refuses to do. It won't inflate numbers — asked to misrepresent revenue, growth, or traction, it declines and explains that investors verify claims during due diligence and one inflated figure ends rounds. And it won't lead with TAM. £40bn market sizing is the most over-used and least convincing first move in early-stage fundraising. Specific traction trumps impressive TAM, every time. "We grew from £2K to £18K MRR in four months" lands harder than "we're disrupting a £50B market."
The output is a one-page narrative spine — the body of a cold email, slides 1-8 of a deck, the script of a 60-second elevator pitch. Numbers come from what the founder provides; the skill doesn't fabricate. Verify every figure before sending. Honesty about gaps beats hidden ones — pre-revenue founders should lead with engagement and insight, not pretend to numbers they don't have. Investors respect honesty and detect spin instantly.
When this triggers
- ·You're starting a raise and need the narrative before you build the deck
- ·Your current deck reads as a product tour, not an investable story
- ·You're writing cold investor emails and the body keeps coming out as 200-word feature lists
- ·You have real traction but can't articulate why this round, this size, right now
- ·You want a one-pager you can send before a meeting that gets the meeting
Example
Trigger
User: 'B2B SaaS, payroll tooling for £1-10M ARR companies. £12K MRR, growing 14%/mo for 5 months. Raising £750K seed. Two founders, both ex-Xero. Help.'
Output
THE HOOK We're growing £12K MRR by 14% month-over-month with zero paid acquisition, selling payroll tooling to companies between £1-10M ARR — the segment Xero outgrew and ADP doesn't notice. THE PROBLEM The £1-10M ARR band has 40-200 employees, complex enough that spreadsheet payroll breaks every quarter, but too small for the £80K/yr enterprise tools. Today they cobble together Xero plus three Zapier hacks plus a part-time bookkeeper and lose a full finance-team day every payroll cycle. THE INSIGHT Everyone assumes this segment graduates upward to enterprise payroll. They don't — they churn back to spreadsheets because enterprise tools are built for HR-led companies, not finance-led ones. We're built finance-first. THE SOLUTION A payroll platform that runs from the same chart of accounts finance teams already use. Closes a payroll run in 40 minutes instead of 6 hours. No HR module — that's a feature, not a gap. THE TRACTION · £12K MRR, 14%/mo for 5 consecutive months · 28 paying customers, zero churn to date · Customer expansion: 6 customers upgraded plans in 90 days · 100% inbound — zero paid acquisition spend THE MARKET UK 1-10M ARR companies with employees: ~12,000. Target 2% in 36 months at £400 ARPU = £1.1M ARR. Expansion: same wedge in IE, NL, DE — finance-led culture rather than HR-led. THE TEAM Both founders led product at Xero on the SME payroll team. Spent 4 years watching this segment churn back to spreadsheets and couldn't change Xero's roadmap to fix it. Now they're fixing it. THE ASK Raising £750K to extend runway to 18 months. Money buys: two engineers, a customer success lead, and HMRC accreditation for direct RTI submission. Milestones: £40K MRR, 100 customers, HMRC live by Q4. WHAT INVESTORS WILL ASK 1. Burn and runway at current spend 2. CAC at zero paid — what happens when you turn it on? 3. Why can't Xero just build this themselves? 4. What's the wedge into adjacent markets? This brief uses the numbers you provided. Verify every figure before sending — investors verify in diligence and a single inflated number ends the round.
