Lacework raised $1.9B including at an $8.3B valuation — then cut 75% of its workforce in 2023 and sold to Fortinet for a fraction of what investors put in
Evaluating only Lacework’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Lacework built cloud security and anomaly detection technology using AI to identify unusual behavior across cloud infrastructure. The company raised $1.3B in November 2021 at an $8.3B valuation — one of the largest Series D rounds in cybersecurity history. But the cloud security market was simultaneously crowded (AWS, Microsoft, Wiz, Orca all competing) and the customer base that Lacework targeted (enterprise cloud teams) was tightening security budgets. After multiple rounds of layoffs — including cutting 75% of the 1,700-person team in a single round in 2023 — Lacework was acquired by Fortinet in 2024 for reportedly well below $200M, a 97%+ markdown from its peak.
Lesson
“Cybersecurity market valuations in 2021 were predicated on a TAM expansion narrative that assumed every enterprise would massively increase cloud security spending post-COVID. When CISOs began consolidating vendors in 2022-2023, the fragmented point-solution space that Lacework occupied contracted sharply.”
