Greylock Partners

About

Greylock Partners is one of the oldest venture capital firms in the United States, founded in 1965 in Cambridge, Massachusetts by William Elfers, Daniel S. Gregory, and Charles Waite ¹². The firm’s name comes from Greylock Road in Wellesley, Massachusetts, where Elfers lived ². Elfers and Waite had both previously worked at American Research and Development Corporation, one of the first modern venture capital firms ².

The firm initially raised $10 million from six East Coast families and focused on Route 128 technology companies, including minicomputers and hardware ². Greylock opened its first West Coast office in Menlo Park in 1999 and relocated its headquarters there from Waltham, Massachusetts in 2009 ². In 2015, the firm separated its Israeli operations into the independent firm 83North ².

Greylock has raised 17 funds over its 60-year history. The 12th fund closed at $500 million in 2005. The 13th fund initially closed at $575 million in 2009 before being upsized to $1 billion in 2011. Subsequent funds have maintained the $1 billion scale: Fund XIV at $1.1 billion in 2013, Fund XV at $1 billion in 2016, Fund XVI at $1 billion in 2020, and Fund XVII at $1 billion in 2023 ²³. In 2021, the firm raised an additional $500 million dedicated exclusively to seed-stage investments, which it described as “the industry’s largest pool of venture capital dedicated to backing founders at day one” ⁴.

As of late 2025, Greylock has over $3.5 billion in committed capital across its funds and has invested in approximately 478 companies ²⁵. The portfolio includes 19 unicorns, 24 IPOs, and 224 acquisitions ⁵. Notable exits include Facebook/Meta (Series B, 2006 — Greylock’s $12.5 million investment was worth $1.5 billion at IPO), LinkedIn (acquired by Microsoft for $26.2 billion), Workday (IPO), and Figma (IPO July 2025 at $13.5 billion market cap) ²⁵⁶.

The current investment team includes 12 partners, 6 venture partners, and a team of specialists in talent, customer development, and marketing ⁷. Asheem Chandna (partner since 2003) focuses on cybersecurity and enterprise software. David Sze (partner since 2000, now Advisory Partner) led investments in Facebook, LinkedIn, and Pandora. Reid Hoffman, co-founder of LinkedIn, joined as partner in 2009 and has since scaled back his active role ²⁷.

Stated Thesis

Greylock publicly describes itself as “Your first partner,” emphasizing that over 80% of its investments are the first institutional check at the pre-seed, seed, or Series A stage ⁸⁹. The firm states its “sole focus is on hearing from entrepreneurs who seek not only funding, but also an engaged partner” ¹⁰.

The firm’s homepage states: “A Partnership. From Day One,” emphasizing collaborative engagement starting from initial conversations, making “no assumptions and fully expect[ing] that key questions remain unanswered” ¹⁰. Greylock positions itself between seed incubators and large multi-stage firms, focusing on founders who arrive with “a deep insight, a kernel of technology vision, and a hunger to solve difficult problems” but without employees, revenue, or existing code ¹⁰.

On check sizes, the firm has stated that typical seed investments range from $2 million to $20 million, described as “large seed checks at lean-in valuations” ⁴. The firm takes a “highly selective, concentrated approach” rather than making “hundreds of loss-leader” bets ⁴.

The firm’s current sector focus, as described on its website, spans AI, Cybersecurity, Infrastructure, SaaS, Consumer, Marketplaces & Commerce, and Fintech & Crypto ⁸. Saam Motamedi has stated the firm’s thesis centers on AI-first companies: “If you’re still thinking about things primarily through a seat-based lens, you’re toast” ¹¹. He envisions “hundreds of tuned co-pilots that make us 10 times more effective and 10 times more efficient at everything that we do” ¹¹.

Asheem Chandna has stated: “We’re fundamentally investing in founders… Sometimes there’s no slides” ¹². He evaluates founders partly on the pace of learning: “If we have three meetings over a period of two weeks, I should see that you’re getting better. It’s about the pace of learning” ¹².

The firm also operates Greylock Edge, a “bespoke 3-month company-building program” for pre-idea, pre-seed, and seed founders, offering “fully flexible financing” including priced seed rounds, uncapped SAFE notes, or no required capital ¹³. The program includes $500K+ in cloud credits from AWS, Google, and Microsoft ¹³.

Inferred Thesis

The following analysis is based on 130 portfolio companies identified on Greylock’s website portfolio page ⁸, supplemented by data from Tracxn ⁵ and Crunchbase ¹⁴. With approximately 478 total investments per Tracxn, this represents about 27% of the full portfolio — the publicly highlighted portion, which likely skews toward the firm’s most notable investments.

Sector Allocation (computed from 130 verified portfolio entries on greylock.com)

Based on the sector tags displayed on Greylock’s portfolio page ⁸, companies are tagged across the following categories (companies may appear in multiple categories):

• AI: 40 companies (31%) — Abnormal AI, Adept, AI Fund, Anthropic, Atomic AI, Aurora, Axiamatic, Baseten, Braintrust, Bretton AI, Chronosphere, Coda, Coffee, Cogent Security, Cresta, Fable Security, Fermat, Gretel, Inflection, Instabase, and others
• Cybersecurity: 22 companies (17%) — 7AI, Abnormal AI, Apiiro, Awake Security, Blockaid, Cato, Censys, Cogent Security, Cribl, Cylake, Dazz, Demisto, Fable Security, Kodem, Palo Alto Networks, and others
• SaaS / Enterprise Software: 20 companies (15%) — Blend, Builder.io, Clockwise, Coda, Common Room, Crew, Cresta, Dropbox, Figma, Gem, Gladly, Hoist, and others
• Consumer: 17 companies (13%) — Airbnb, Boost, Caavo, Coinbase, Discord, Facebook, Handshake, Houseparty, Instagram, Inflection, and others
• Infrastructure: 16 companies (12%) — AppDynamics, Arista Networks, AVI Networks, Baseten, Builder.io, Cato, Chronosphere, Cloudera, Delphix, Docker, Domo, Gretel, Innovium, and others
• Fintech & Crypto: 14 companies (11%) — 0x Labs, Aspora, Atomic, Ava, Blend, Blockaid, Bretton AI, Boost, Chia, Coinbase, Espresso, Frec, and others
• Marketplace & Commerce: 12 companies (9%) — Airbnb, AirOps, Amplify MD, Builder.io, Cleo, Discord, Fermat, GoFundMe, Highstock, Instawork, Inventa, and others

Note: Many companies are tagged with multiple sectors (e.g., Abnormal AI is both “AI” and “Cybersecurity”), so percentages total more than 100%. The primary signal is that AI dominates the current portfolio positioning, followed by cybersecurity and enterprise SaaS.

Stage Distribution

According to Tracxn data ⁵: Greylock has made 159 Series A investments (33% of total), 150 seed investments (31%), and 86 Series B investments (18%), with the remainder at later stages. The firm states that over 80% of investments are first checks ⁹, though the Tracxn data shows a meaningful Series B allocation as well. F4.fund reports check sizes of $300K-$800K at pre-seed, $1M-$3M at seed, and $3M-$10M at Series A ⁹.

Geographic Concentration

Greylock is headquartered in Menlo Park, California and primarily invests in US-based companies ⁹. The portfolio includes some international companies, notably in Israel (Cato Networks, Apiiro, Kodem — reflecting partner Mor Chen’s focus on Israeli founders in cybersecurity and enterprise AI) ²⁷.

Check Size

• Pre-seed: $300K-$800K ⁹
• Seed: $1M-$3M, though the firm has described seed checks ranging up to $20M for the dedicated seed fund ⁴⁹
• Series A: $3M-$10M ⁹
• Growth/Later stage: Up to $200M in select cases ⁹

Investment Volume

Greylock made 23 investments in 2025 and 4 investments in the first two months of 2026 ⁵. This pace of approximately 25-30 investments per year is far lower than spray-and-pray firms like SV Angel (100+/year), reflecting Greylock’s concentrated, high-conviction approach.

Co-Investor Patterns

Based on the five profiled startups where Greylock appears as a co-investor in the Seedlist database (Okta, Airbnb, Facebook, Coinbase, Figma), frequent co-investors include Andreessen Horowitz, Sequoia Capital, and Kleiner Perkins. The firm frequently co-invests with top-tier Silicon Valley firms and takes board seats in portfolio companies ⁹.

Notable Gaps Between Stated and Actual Thesis

• AI concentration is newer than it appears: While the current portfolio page highlights AI heavily (31% of listed companies), many of these are recent investments (2022-2026). Greylock’s historical portfolio was more evenly split between consumer internet, enterprise SaaS, and infrastructure. The AI-first positioning represents a strategic pivot under Fund XVII.
• Cybersecurity is a quiet strength: Cybersecurity represents 17% of the highlighted portfolio and has been a consistent focus through Asheem Chandna since 2003. His track record includes Palo Alto Networks ($250K seed to $50B+ market cap), Wiz (valued at $12 billion), and Abnormal AI (valued at $5.1 billion) ¹²¹⁵. This concentration is not always front-and-center in the firm’s marketing.
• Consumer has diminished: Despite iconic consumer investments (Facebook, LinkedIn, Instagram, Discord, Airbnb), the firm’s current portfolio skews heavily toward enterprise and AI. Only 13% of currently highlighted portfolio companies are tagged “Consumer.”
• Check sizes are larger than typical seed funds: The firm’s $2M-$20M seed check range and willingness to invest up to $200M positions it differently from most seed-stage investors. Greylock competes for deals at Series A valuations while calling them “seed” investments.
• Board seats differentiate from SV Angel model: Unlike SV Angel’s non-lead, no-board-seat approach, Greylock leads rounds and takes board seats, providing governance-level engagement ¹⁰⁹.

In Their Own Words

Asheem Chandna on founder evaluation:

“If you email me and you’re a founder who wants a meeting, the first thing I’m going to ask you for are documents. I don’t always get it, but I probably get it 75% of the time. Then, if the document isn’t highly precise, it’s highly unlikely you’re somebody we want to fund.” (Source: Fortune, February 2025) ¹²

Asheem Chandna on learning pace:

“If we have three meetings over a period of two weeks, I should see that you’re getting better. It’s about the pace of learning. If after three meetings, there’s really no advancement, how can I know you’re a learner?” (Source: Fortune, February 2025) ¹²

Saam Motamedi on controversial bets:

David Sze on the Facebook IPO:

“It was very electric. It was a real sense of achievement.” (Source: Boston Globe, May 2012) ⁶

David Sze on winner-take-all dynamics:

“Does this show the potential to be a winner takes most or winner takes all kind of business, if that’s the case, and you think you have the right team in place as well, which is the other critical aspect of that.” (Source: The Twenty Minute VC) ²¹

Greylock on the seed fund philosophy (2021):
