Seed Funding
The first significant round of external capital a startup raises, typically used to validate the product, build the initial team, and find product-market fit.
What is Seed Funding?
Seed funding is usually the first institutional or angel investment a startup receives. Typical seed rounds range from $500K to $5M, though the range varies widely by market and geography.
Seed capital is used to go from idea to early traction: building the product, hiring the founding team, acquiring first customers, and validating that there's a real market for what you're building.
Seed rounds are often structured as SAFEs (Simple Agreement for Future Equity) or convertible notes, which defer the valuation discussion to the next priced round. Some seed rounds are priced (with a set valuation and equity percentage).
Why it matters
Seed funding sets your initial runway clock. A $2M seed round with a $100K/month burn rate gives you 20 months to prove your thesis. How you deploy that capital determines whether you reach the milestones needed for the next round.
The amount you raise and the valuation you accept at seed stage have long-term implications for dilution and future fundraising. Raising too little means running out of runway before proving anything. Raising too much at a high valuation creates pressure to grow into that valuation.
Example
A startup raises a $1.5M seed round. Planned team of 5 people costs $60,000/month. Tools and infrastructure cost $5,000/month. Total burn = $65,000/month. Runway = $1,500,000 / $65,000 = 23 months. That gives roughly 18 months of execution plus 5 months buffer for fundraising.
How RunwayCal helps
RunwayCal helps seed-stage founders model how their seed capital translates to runway. Define your team, tools, and expected revenue, and see exactly how many months your seed round buys you — and what milestones you can hit in that window.
Common mistakes
- 1Raising a seed round without a clear plan for how the capital will be deployed
- 2Underestimating how quickly burn rate grows as you hire (each person adds $8K-$20K+/month)
- 3Spending the first 6 months of seed capital on product without validating customer demand
