BULWARKSecurity Capital

For founders

Built for the people building the defense.

If you are building in security, we are the fund that understands your buyer, your hiring problem, and your technology before you finish explaining them.

What we offer beyond capital

100%

Partners from security

A partner who speaks security

You will not spend the first meeting explaining what a CISO is or why detection is hard. Every partner has built or defended in security.

In-house

Talent function

The hardest hires, sourced

Our talent function recruits the founding engineers, detection leads, and enterprise sellers that decide a security company's trajectory.

Warm

Intros to buyers

Warm doors to real buyers

Design partners and first customers from a standing network of security leaders who take our calls.

Reserves

For the next round

Capital that compounds

We reserve heavily for follow-on and lead the rounds that matter.

How it actually starts

No form funnel. A short, specific note — the problem, the wedge, and why you — sent directly to a partner who already knows your space. The founders who get the fastest yes are the ones who skip the pitch-deck throat-clearing and open with the insight.

"We're the only team that's shipped detection for non-human identity at Fortune 500 scale. Attackers already know this gap exists. We think you'd want to see why."

The kind of opening line a partner replies to personally

How we work

We keep a low profile. On purpose.

The people we invest in defend systems adversaries are actively trying to break — so the people investing in them shouldn't become a second attack surface. We'd rather be known by the companies we invest in than by the noise we make about ourselves.

The next line of defense

If you're building it, we want the first call.

We lead early, hold conviction, and stay through the rounds that matter.
