Pre-Pitch Briefing

Adrian Radu

Partner at Khosla Ventures

Check size: No current personal check range is published. Khosla's Seed Fund backs experiments and its Main Fund covers early through later stages, including total financings above $10M; a 2020 interview described historical seed checks around $1M–$2M. These are firm-level guideposts, not Adrian's personal authority.

Their Thesis

Adrian is an early-stage generalist whose prior portfolio and advisory work span fintech, enterprise software, cybersecurity, defense, productivity, and frontier technologies. His biography emphasizes partnering before defining strategic moments rather than arriving only for transactions; the relevant lens is whether a bold founder has an unfair advantage, a billion-dollar market, and a disciplined plan to remove the most important technical and market risks.

How to Pitch Them

Lead with the non-obvious opportunity, why now, and the unfair advantage. Name the largest technical, market, and execution risks and the financing milestones that will retire them at the lowest cost. Show why the market can exceed $1B and how the initial wedge can become a category. Because Adrian has seen both early investing and strategic exits, be crisp about durable standalone value rather than pitching an acquisition story.

What Excites Them

Founders early in the journey, ambitious technology categories, differentiated approaches, and teams capable of navigating consequential strategic choices. His Lightspeed record—Flex, Moment, Payhawk, Stripe, Anduril, Wiz, ClickUp, and Lightyear—signals comfort across software, fintech, security, defense, and frontier systems.

What They Pass On

No personal pass list is public. Khosla's framework implies weak fit for small markets, copied products, founders seeking only capital, teams unable to name the key risks and missing pieces, and seed plans that spend broadly rather than eliminate the most consequential uncertainty cheaply.

Key Frameworks

Defining-moment map

Identify the strategic decisions most likely to determine company trajectory—market entry, financing, product expansion, geography, partnership, or M&A—and evaluate the options before urgency removes leverage.

Early-risk ladder

Rank technical, market, team, and distribution risks by existential impact, then fund the cheapest credible experiment that removes the top risk and creates the next financing option.

Standalone-value test

Even when strategic buyers may exist, underwrite the company around a durable independent category, defensible economics, and compounding customer value rather than an assumed acquisition exit.
