History

Founding and Early Years

Greylock Partners was founded in 1965 in , by William (Bill) Elfers and Daniel S. (Dan) Gregory, with Charlie Waite joining shortly thereafter as a third partner. Elfers, a veteran of American Research & Development Corporation (ARD), one of the earliest firms, sought to establish his own operation after leaving ARD, drawing on his experience in funding technology startups. The firm's name derives from Greylock Road, the street in , where Elfers resided at the time. The inaugural Greylock fund raised $10 million in commitments from a small group of six wealthy East Coast families, positioning it as one of the pioneering structures in during the emerging post-World War II investment landscape. This modest capital base reflected the firm's initial setup as a boutique partnership, emphasizing close-knit decision-making among its founders rather than a large institutional model. Operating from Boston-area offices, Greylock concentrated on the burgeoning East Coast technology ecosystem along Route 128, where proximity to universities and research institutions like MIT facilitated access to innovative talent and ideas. During its early years amid the minicomputer revolution of the late 1960s and , Greylock directed investments toward hardware and software ventures that capitalized on the shift from mainframes to more accessible systems. Notable examples include its funding of Data General Corporation, a key player in minicomputer design that went public in 1968, and , which achieved an IPO in 1974 and became a leader in multi-user systems. These investments underscored Greylock's role in nurturing the hardware innovations driving the era's expansion, while the firm maintained a lean structure with a handful of partners to foster hands-on involvement in portfolio companies.

Expansion to Silicon Valley

In the late , as the boom accelerated, Greylock Partners sought to expand its reach beyond its East Coast roots by establishing a presence in . In 1999, the firm opened its first West Coast office in , hiring from to lead it; Bhusri, in his inaugural venture investing role, focused on opportunities to capitalize on the burgeoning tech ecosystem. This move positioned Greylock to participate more actively in the dot-com era, though the subsequent bust in 2000 tested the firm's resilience. To recover from the market downturn, Greylock navigated the early 2000s by emphasizing stable investments through its new outpost, led by partners like Bhusri, while gradually broadening into internet sectors. In 2000, joined as a partner, bringing expertise from media and product development at companies like Excite@Home; his arrival marked a strategic pivot toward social platforms and network-driven businesses, influencing Greylock's growing emphasis on high-growth tech amid the post-bust recovery. This dual focus on enterprise stability and potential helped the firm rebuild momentum, with investments in areas like and software infrastructure sustaining operations through the decade. By the mid-2000s, Greylock's Silicon Valley operations had gained significant traction, prompting a full relocation of its headquarters from Waltham, Massachusetts, to Menlo Park in 2009 to align more closely with the epicenter of innovation and talent. This shift underscored the firm's commitment to West Coast opportunities in consumer internet and enterprise software, where it had cultivated key partnerships and deal flow. Concurrently, Greylock's international arm in Israel, established as Greylock IL, operated independently but remained affiliated until 2015, when it rebranded and separated as 83North, raising a $200 million fund to pursue European and Israeli tech ventures autonomously.

Evolution of Funds

Greylock Partners raised its second fund in 1973, marking an expansion beyond the initial $10 million committed by a group of six families in 1965.

In 2021, Greylock complemented its 16th fund with a dedicated $500 million extension to support pre-seed and seed-stage opportunities. By 2025, Greylock had amassed over $3.5 billion in total committed capital across its funds, continuing to emphasize early-stage venture investments despite the larger pool of resources.
