Frequently Asked Questions

How much should I raise in a Seed round for a Life Sciences startup?

Life Sciences startups at the Seed stage typically raise $500K-$3M. 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 Seed round?

In the Seed stage, investors typically target 15-25% ownership. The exact dilution depends on your valuation, which in Life Sciences 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 Seed dilution compounds with future rounds.

What are the most important metrics for raising a Seed round in Life Sciences?

Life Sciences investors at the Seed stage focus heavily on the leading indicators that predict long-term success. The metrics section above outlines the most critical ones. At the Seed 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.

Based on typical market cycles, Seed fundraising processes for Life Sciences companies take 2–4 months to close from process start.
