What check size do series b cybersecurity VCs write?

Among 18 series b cybersecurity funds on DryPowder, check sizes run from $500K–$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 b cybersecurity VC?

A warm intro is still the fastest path. Most series b 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 B process take, and how is it different from Series A?

Series B processes typically run 3-6 months and are significantly more diligence-intensive than Series A. Investors will conduct deep cohort analysis, churn reviews, and GTM efficiency audits. Most Series B investors want to lead or co-lead, so you are running a smaller, more targeted process than at earlier stages. Financial modeling and competitive positioning matter as much as the founding narrative at this point.

How many series b 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 15 series b 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 18 series b 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.
