When to start Series A conversations?

6-12 months before you need the capital. Build relationships with 15-25 target Series A funds during seed traction phase. First formal meetings once metrics are 60-80% of the bar.

Which funds lead Series As now?

Sequoia, Founders Fund, a16z, Accel, Benchmark, Lightspeed, Kleiner, Redpoint, GV, IVP, Bessemer, Insight, Menlo Ventures, plus verticalized funds.

What if we can't raise Series A?

Options: extend runway via bridge round, focus on getting to cash-flow neutral, consider acquisition. Don't force a Series A at bad terms — the follow-on math destroys the company.

Series A: The Metrics Bar, Investor Set, and Process (2026)

Series A is where hobby companies die and real companies begin. Here's what investors require and how the process runs today.

Series A Fundraising for Startups

Series A is a different animal from seed. The bar is quantitative — repeatable metrics, not vision. The investor set is smaller, more institutional, and more analytical. The process is 3-6 months, not 6 weeks.

The modern Series A bar

B2B SaaS: $1-3M ARR, growing 3x+ YoY, 100%+ NRR, clear ICP. Consumer: 100K+ engaged users, strong retention curves, initial revenue signal. Deep tech: technical validation + first commercial pilot. In every case: a repeatable acquisition channel and clear use of proceeds.

Size and structure

$8-15M typical. $40-80M post-money valuation. Priced round (SAFEs get cleaned up). Lead investor takes 15-25% ownership, plus board seat. Existing seed investors often pro-rata. Typical process: 3 months of meetings, 4-6 weeks to term sheet, 6-10 weeks to close.

What investors evaluate

Sales efficiency (magic number, burn multiple, CAC payback). Cohort retention. Pipeline conversion rates by segment. Founder-led selling → sales rep transition data. Product-market fit signal (referral rate, organic growth, sales cycle compression). Path to $10M ARR.

Common reasons Series A doesn't close

Growth rate below 2x YoY (hard threshold now). NRR under 100% (signals product doesn't compound). Founder-led sales masking a broken motion. Concentration in a single customer segment or channel. Cap table complexity from too many seed investors.
