Four ventures · Three founders · Zero VC

SLEET LABS

A cybersecurity studio of three founders.
Four narrow ventures. Agents run the work; we supervise.
Zero venture capital.

Scroll  ·  the studio below

Three lines, written down.

Narrow products. Agents do the work. No venture capital. The three rules below don't bend when the market changes.

01 — Surface

Narrow products. No platforms.

Every venture is one workflow, done end-to-end. A questionnaire engine. An outbound-email engine for one segment. A founder-grade SOC. A funding-signal feed. We don't widen the brief. The market already has too many platforms.

02 — Operation

Agents operate. Operators supervise.

Day-to-day work is run by language-model agents. The remaining slice is three founders with 20 years combined across cybersecurity and product security. We review the work; we don't direct it.

03 — Capital

Zero venture capital.

No round, no pitch deck, no board. The studio sells software, not optionality. Profitability before scale. No round means we can wait for the right customer.

Four fronts.

Each portfolio company is a narrow product for a painful, well-understood B2B workflow. Two live, two in build. None of them platforms.

The balance sheet.

No venture capital. No employees by design. The savings buy patience.
