Fractional CFO for Series A & B Startups
Strategic finance leadership, without the $400K hire.
Most Series A startups don't need a full-time CFO yet — but they do need someone who can build a board deck, defend a forecast to investors, and tell the founder when the burn math doesn't work. That's what we do.
What we do
What a Pegacorn fractional CFO actually does
- Board and investor reporting
- Monthly and quarterly reporting packages that match what institutional investors expect to see. Variance analysis, KPI dashboards, cash runway.
- Fundraise preparation
- Financial models built for diligence. Data rooms organized. Cap table reconciled. We've helped clients close Series B rounds.
- Forecasting and scenario planning
- Bottoms-up models that founders can actually defend. Hiring plans tied to revenue assumptions. Runway scenarios at multiple burn rates.
- Strategic decisions
- Pricing, unit economics, build-vs-buy, headcount timing, geographic expansion. We sit in on the calls where these decisions get made.
When founders hire us
Signals it's time
- You've closed a Series A and your investors want quarterly reporting you can't yet produce
- You're 6–9 months from raising again and need a model that will survive diligence
- Your in-house bookkeeper is great at AP/AR but can't help with strategy
- You're hiring a controller, then a VP Finance, then a CFO — and you need someone now to bridge that
Pricing
Fractional CFO retainers start at $5,000/month for a defined monthly scope. Most Series A and B clients engage in the $5K–$10K range depending on board cadence, fundraise activity, and reporting complexity. No setup fees. No long-term contracts. Month-to-month.
