Why Now Is a Good Time to Pitch These Funds

Market timing context for Series B investors

Fresh Dry Powder

Funds that have filed with the SEC in the last 12 months are still in active deployment mode. The earlier in a fund's cycle you pitch, the more receptive GPs tend to be — they have capital to put to work and portfolio construction is not yet locked in.

Verified Activity Signals

Every fund listed here has a recent SEC Form D filing, confirming they have raised capital and are authorized to invest. This eliminates zombie funds that are listed on directories but are no longer writing checks.

Deployment Urgency

Most VC funds have a 3–5 year deployment window. Funds with recent filings face internal pressure to invest their committed capital within that window, making them more likely to move quickly when they find a strong fit.

Frequently Asked Questions

What is a Series B investment and how large are the checks?

A Series B investment is a growth round for companies that have achieved product-market fit at scale and are ready to expand into new markets, geographies, or verticals.. Check sizes at this stage typically range from $15M – $50M. The exact amount depends on valuation, how competitive the deal is, and whether co-investors are participating in the round.

How many Series B investors are actively writing checks in 2026?

Our database shows 100 Series B investors with SEC Form D filings from the last 12 months, indicating active capital deployment. This number fluctuates as new funds close and established funds fully deploy their capital.

What metrics do Series B investors expect to see?

Series B investors look for $5M–$15M+ ARR, consistent 60–100% YoY growth, strong net revenue retention (>110%), and a clear competitive moat. Investors at this stage also weigh team composition heavily — relevant domain expertise and a track record of execution matter as much as the numbers.

How do I find the right Series B investor for my startup?

Filter by industry above to see Series B investors in your specific sector. Then review each fund's portfolio on their website to confirm they invest in similar companies. Prioritize funds where you can get a warm introduction through shared investors, advisors, or portfolio founders.

How long does a Series B fundraise typically take?

Most founders spend 2–4 months on a Series B round, from first outreach to signed term sheet. Allow another 4–8 weeks for legal documentation and closing. Starting the process 3–6 months before you run out of runway is strongly recommended to avoid negotiating from a position of weakness.
