Partnering with early-stage entrepreneurs since 1965. 100+ IPOs. 250+ acquisitions.
We’re constantly asked what great founders do differently when hiring their founding team. Most early-stage founders are recruiting from the same talent pool: Top companies. Top universities. Top technical credentials. The challenge is that everyone else wants those people too. And when you’re building an early-stage startup, you’re often competing without the brand, scale, or resources of much larger companies. In this episode of In Practice, Abby Hart from Greylock’s Core Talent team shares what she has seen the strongest early-stage founders do differently, including: • How to spot high-potential candidates beyond the obvious signals • Where founders can afford to take hiring risks • Why earning a candidate’s belief matters so much at the earliest stages Watch the first episode of In Practice, our series on actionable advice for building an early-stage company.

Huge THANK YOU to everyone who joined us for Greylock Techfair 2026 at Oracle Park last week! The energy all night was infectious. Bringing together 600+ students and 35 startups sparked countless new connections and meaningful conversations among an incredibly talent-dense community of builders and founders. Thank you to the teams from @OpenAI, @tryramp, @baseten, @AppliedInt, @nuro, @cognition, @harvey, @glean,@instawork, @Modular, @cresta, @SnorkelAI, @llama_index, @opal_sec, @Onehousehq @BedrockDataAI, @axiamatic, @CylakeAI, @PayWithLocus, Forge, @cogent_security, @lightfld, Mandolin, @Netic_AI, @ListenLabs, @altaratech, @FableSecurity, @PoeticHQ, @SuperMeAI, Ahum AI, and others (still in stealth) for taking the time to meet with students and offer them a closer look at what you're building. Already counting down to next year.
“The biggest mistake you can make in AI is underestimating the size of the wave or treating it as a binary outcome.” @saammotamedi on @tbpn
Today we're introducing Oak, the AI-native Identity Operating System. Every enterprise now runs on identities its security tools were never built to see: machines, service accounts, and a fast-growing population of AI agents. Legacy identity governance was built for a static world of human users, and it can't keep pace. Oak builds a live identity graph across every application and identity type, then governs the full lifecycle by comparing the access each identity holds against what it actually uses, with real-time risk decisions and root-cause remediation. The founders know this problem well. Shai Morag has built and sold three security companies. Tal Marom led product teams at Tenable and Salesforce. Together they've assembled a team of identity and AI veterans from across the industry. Greylock is co-leading Oak's $60M seed round, alongside @Accel and @CRV. We're partnering with Shai, Tal, and the team as they build the control plane for every identity, human and non-human alike. Read our investment blog 👇
Today, we are officially announcing Greylock 18, our new $1.5 billion early-stage fund. @chandna and @saammotamedi sat down with Natasha Mascarenhas(@nmasc_) from @business to share our take on this moment in AI, our concentrated approach to backing founders, and why we believe the biggest companies of this wave are still ahead.

We are thrilled to share that @glennkelman has joined Greylock as an Executive in Residence. Glenn co-founded Plumtree Software, which went public in 2002, and spent nearly two decades as CEO of @Redfin, building it into the leading technology-powered real estate brokerage. At Greylock, he'll work directly with founders on leadership, company building, and the hard parts of scaling that don't fit neatly into a board deck. We know from working alongside entrepreneurs that building a great product is only part of the journey. The personal growth required to lead a company through every stage of scaling matters just as much. Early in his time at Redfin, Glenn was under enormous pressure and trying to do it all alone. A Greylock partner played a formative role in helping him find a different way to lead. In his own words: "A Greylock partner named James Slavet took me on a walk along a strip of airport hotels by the Bay. He made me feel that I was supported, but also that I could change. After that walk, I told our board what was really wrong with our business, so we could work together on how to fix it. I began trying to become a better colleague to all the beautiful Redfin people who made me successful. If I could go on a walk like that with any of you, my work here would be done." Welcome, Glenn!

"The attacker, the target, and the buyer have all changed. Security thinking has not caught up." Earlier this week, Greylock and @mantisVC brought together CISOs and security founders for a conversation moderated by @AlextPallNY (The Chainsmokers & Mantis VC founder). On the
1) The attacker: AI has lowered the skill floor for attackers. What looks like a nation-state threat may be a script with a prompt behind it. The techniques that once required deep expertise are now packaged, accessible, and increasingly automated.
@mantisVC 2) The target: Attackers are not just coming for your systems anymore. The new play is to impersonate a vendor you trust, then use that foothold to reach your customers. Your customer relationships are part of your threat surface now.
@mantisVC 3) The buyer: The most sophisticated buyers have stopped touching UI. With MCP crossing 97 million monthly SDK downloads and over 10,000 production servers, API-first infrastructure is no longer an edge case.
@mantisVC One common theme: AI agents went from nice-to-have to must-have. The buyers who were figuring it out are now actively buying. The security companies that get this are building headless, API-first. That is a different product instinct entirely, and most incumbents do not have it
