Investment Strategy
Each Greylock partner makes one to two new investments per year, a concentration model that distinguishes the firm from multi-stage platforms that spread attention across dozens of companies.
Post-investment, Greylock's in-house talent, recruiting, customer development, and marketing teams work actively alongside portfolio companies: sourcing more than half of early engineering, design, and product hires, helping land the majority of initial enterprise customers, and supporting messaging, positioning, and company launches.
The firm partners with founders from the earliest stages and maintains relationships through IPO and beyond.
