Frequently Asked Questions

How much should I raise in a Series B round for a FinTech startup?

FinTech startups at the Series B stage typically raise $15M-$50M. The right amount depends on your burn rate, team size, and the specific milestones you need to hit before your next raise. A common rule of thumb is to raise 18–24 months of runway. Raising too little risks running out of capital mid-traction; raising too much can dilute founders and set unrealistic valuation expectations for the next round.

What equity percentage will I give up in a Series B round?

In the Series B stage, investors typically target 15-25% ownership. The exact dilution depends on your valuation, which in FinTech is driven by team pedigree, market size, and early traction signals. Use a dilution calculator to model scenarios before entering negotiations and understand how the Series B dilution compounds with future rounds.

What are the most important metrics for raising a Series B round in FinTech?

FinTech investors at the Series B stage focus heavily on the leading indicators that predict long-term success. The metrics section above outlines the most critical ones. At the Series B stage, the key is demonstrating that you understand the right metrics for your business — even if you haven't yet hit all benchmarks — and that you have a credible plan to reach them with the capital raised.

How long does it take to close a Series B round in FinTech?

Based on typical market cycles, Series B fundraising processes for FinTech companies take 4–6 months to close from formal process launch. This includes preparation time (1–4 weeks), running the process (4–10 weeks), and legal close (2–6 weeks). Having your data room, cap table, and metrics deck ready before the first meeting can materially shorten the timeline.

Which types of investors are most active in FinTech at the Series B stage?

The most active capital sources for FinTech startups at the Series B stage include: Growth equity funds ($500M–$3B AUM), Multi-stage VCs with growth arms, Crossover funds (Coatue, Tiger, D1), International sovereign funds, Strategic investors and CVCs. Specialized FinTech funds that understand sector-specific metrics are often more efficient partners than generalist investors — they do less primary diligence and can add more sector-relevant value post-investment.
