How many series a cybersecurity investors are actively deploying right now?

DryPowder tracks 31 series a cybersecurity funds. Of these, 26 are currently deploying capital based on recent fund closes, portfolio activity, and partner signals. Use DryPowder's fund matching to see which ones fit your specific startup.

What check size do series a cybersecurity VCs write?

Among 31 series a cybersecurity funds on DryPowder, check sizes run from $100K–$100M. Ranges vary by fund size, vintage, and whether the fund leads rounds. Each fund profile shows check size detail and lead preference.

How do I get a meeting with a series a cybersecurity VC?

A warm intro is still the fastest path. Most series a cybersecurity VCs on DryPowder do accept cold outreach or direct applications, but response rates vary widely by fund. Before reaching out, use DryPowder's AI matching to get a fit score and specific talking points. Founders who lead with thesis-aligned framing get significantly better response rates than those sending the same deck to every fund on a list.

How long does a Series A process typically take?

Series A processes average 4-6 months. Unlike seed, you will navigate formal partner meetings, IC presentations, data room reviews, and reference calls. First meeting to term sheet alone takes 6-10 weeks at most firms. Running a compressed, competitive process where you approach all target investors in the same short window tends to produce faster decisions and better terms than a sequential approach.

How many series a cybersecurity investors should I be talking to at once?

Most fundraisers recommend a parallel process: identify 20-40 target investors but approach your highest-fit funds first. Of the 26 series a cybersecurity funds currently deploying, not all will match your specific stage and sector. Use fund matching to find your top 10-15, approach those first, collect feedback, then go wider. Going to every fund simultaneously without qualifying first burns bridges and dilutes the urgency that helps close a round.

How is DryPowder different from building a VC list on LinkedIn or Crunchbase?

The fund list you build on LinkedIn or Crunchbase is roughly the same list every other founder is building. DryPowder adds three things a manual search cannot: deployment signals (which funds have recently closed new vehicles and are actively writing checks), AI thesis matching (which of the 31 series a cybersecurity funds actually fits your specific startup, ranked by fit), and verified partner contact details. The goal is 15 targeted, thesis-aligned pitches instead of 150 generic ones.
