Guru Chahal

Guru Chahal is a senior Partner at Lightspeed Venture Partners, where he invests in enterprise AI, cybersecurity, cloud infrastructure and developer tooling. A co-founder of Avi Networks (acquired by VMware) and earlier of Nuova Systems (acquired by Cisco), his Lightspeed investments include Anthropic, Chainguard and Cyera.

Guru walked through his investment framework across the AI stack, tailored to a UK government audience and spanning infrastructure, security, healthcare and defence.​

He described investing across three layers: systems and hardware, including more efficient chips, data centre networking and tooling that compresses chip design; foundation models, where Lightspeed was an early Anthropic investor and sees near-insatiable demand for frontier intelligence; and an enablement layer of cybersecurity, observability and developer tooling. The UK's £1.1B hardware programme, he noted, aligns with the view that nations serious about the AI economy must own their infrastructure substrate.​

On security, he flagged how the time from a known exploit to active attack has collapsed from months to hours, recommending two LSVP portfolio baselines for government: A Security, to surface your own vulnerabilities first, and Chainguard, as a secure clearinghouse for open-source. ​

In healthcare IT, he cited the automation opportunity in documents and language, pointing to Abridge's ambient scribe and a certified AI doctor in Utah able and legally authorised to order prescription refills autonomously. On defence, he observed that AI is increasingly seen as necessary given adversaries operating by different rules, reflecting changed geopolitics and the rise of defence-tech companies like Anduril and Helsing. He also noted that shifting public perception of AI in policing remains largely a matter of public education.
