Lacework, which helps protect cloud environments from data breaches, raises $42M from Sutter Hill Ventures and Liberty Global Ventures

Context & Ripple Effects
This $42M round is the middle beat of a five-year Lacework funding arc that the coverage traces end to end: after its $24M Series B in August 2018, also led by Sutter Hill Ventures, this raise keeps Sutter Hill doubling down while Liberty Global Ventures comes in as a new backer.
What makes the round worth revisiting is where the arc lands — two more mega-rounds ($525M at a $1B+ valuation and $1.3B at an $8.3B post-money) in 2021, a 20% layoff of a 1,000-person workforce in May 2022, and finally Fortinet agreeing to buy the company in June 2024.
First-order effects
- Lacewalk's runway for automated container and workload security extends materially, with Sutter Hill now a three-time backer across the 2018 Series B and both 2019 tranches' lead investors.
- Liberty Global Ventures gains an early position in cloud-native security just before the category's 2021 funding peak, entering alongside an existing insider rather than competing for allocation.
Second-order effects
- The round helped set the template rivals chased: once Lacework reached unicorn territory via the $525M Series D, peer cloud-security startups faced pressure to raise at comparable scale to fund agent-based detection and compliance tooling.
- Sutter Hill's repeated participation signaled to late-stage funds like Tiger Global that the category was de-risked, paving the way for the $1.3B round at an $8.3B valuation eighteen months later.
Third-order effects
- The full arc — modest early rounds, hyper-inflated 2021 valuations, layoffs within six months of the peak round, and absorption by Fortinet — sketches how cloud-security startups became consolidation targets for platform incumbents once standalone growth stalled.
- If the pattern holds, early-stage specialist investors capture the durable returns while late-stage entrants at peak valuations absorb the downside, pushing venture risk-taking earlier in the cloud-security stack.
The trend: Cloud-native security startups rode a 2019-to-2021 venture supercycle from tens-of-millions rounds to multi-billion valuations, then consolidated into incumbent platforms when growth normalized.
