Frequently Asked Questions
+−What is the difference between seed and Series A funding?
Seed funding (typically $25K-$2M) is the earliest stage capital used to validate ideas and build initial products. Series A funding ($2M-$15M+) comes after product-market fit is demonstrated and is used for scaling sales, team, and market expansion.
+−How long does the fundraising process take?
A typical seed round takes 3-6 months, while Series A rounds can take 6-9 months. This includes time for due diligence, negotiations, and legal closing. Warm introductions and being investor-ready can significantly accelerate the timeline.
+−What equity stake do founders typically give up in seed rounds?
Seed rounds typically involve 10-20% equity dilution per round. The exact amount depends on valuation, funding amount, and negotiation. Keep in mind that each subsequent round will also dilute equity, so plan for 30-50% total dilution by Series B.
+−What makes a startup attractive to investors?
Investors look for: (1) strong founding team with relevant expertise, (2) large addressable market ($1B+), (3) unique solution to real problem, (4) early traction/proof of concept, (5) clear path to profitability, (6) differentiated business model.
+−How much runway should a startup have?
Ideally 12-24 months. Seed-stage startups typically aim for 18 months of runway after raising, while growth-stage companies should have 24+ months. This gives time to hit milestones and prepare for the next funding round.
+−What's the average salary at a Series A startup?
Varies significantly by role, location, and company stage. Engineers typically earn $120K-$180K salary + 0.1-1% equity. Non-technical roles earn 20-30% less. Early-stage startups often pay below market rates, compensating with larger equity packages.
+−How do I evaluate a startup job offer?
Consider: (1) Base salary vs. market, (2) Equity percentage and vesting schedule, (3) Funding runway, (4) Team quality and experience, (5) Product-market fit stage, (6) Growth trajectory, (7) Company culture and values alignment.
