Kleiner PerkinsCheck size: No personal check range or signing authority is published. Lucas participates across early and growth investments; disclosed company financings should not be treated as his personal range.
Lucas invests in enterprise software and cybersecurity across early and growth stages. His portfolio connects foundation models, data and enterprise AI, open-source software security, managed security, offensive-security automation, operational resilience, physical safety, autonomy, defense, and space. His software private-equity background adds a durable-business lens to technically ambitious companies.
Security products that produce measurable protection or recovery, enterprise systems with mission-critical adoption, technically differentiated teams, durable software economics, and frontier infrastructure that has crossed from concept to commercial reality without compromising safety or reliability.
The disclosed portfolio implies weak fit for security theater, prevention-only products that ignore recovery, AI claims without safety or enterprise trust, infrastructure with no repeatable commercial deployment, and growth that cannot withstand durable-software diligence on retention, margins, or competitive position.
For security, define the threat model, protected asset, control point, measurable reduction in risk, false-positive burden, recovery path, and proof from production. For enterprise software, bring retention, workflow depth, trust, and unit economics. For autonomy or defense, include safety evidence, mission reliability, procurement, hardware/software integration, and commercial scale.
Assume some attacks and infrastructure failures are inevitable; evaluate both prevention controls and the continuously tested ability to contain, recover, and prove continuity.
Trace the threat model to telemetry, detection or control, operator action, outcome, and independently measurable reduction in exposure; avoid claims that stop at alerts.
A frontier system becomes infrastructure when commercial usage is repeatable, reliability and safety improve at scale, integration is standardized, and customers behave as though it is indispensable.
Autonomy becomes infrastructure when a system moves beyond proof of concept to repeatable commercial scale while maintaining a statistically stronger safety record and public trust.

“The most important technology shifts become infrastructure.”
