Mamoon Hamid

Background

Mamoon Hamid is a Partner at Kleiner Perkins, where he joined in August 2017 as Managing Member and General Partner to lead the firm’s next generation ¹. He was born in Pakistan and spent most of his early life in Frankfurt, Germany, before moving to the United States ².

Hamid earned a B.S. in Electrical and Computer Engineering from Purdue University ², an M.S. from Stanford University, and an MBA from Harvard Business School ¹.

He began his career as an engineer at Xilinx, a Kleiner Perkins-backed company, in 1997, spending six years there in engineering, product, and marketing roles ^{1 2}. He entered venture capital in 2005 at US Venture Partners (USVP), where he became a Partner ¹. In 2011, he co-founded Social Capital, where he led investments in Slack, Intercom, Greenhouse, Netskope, and Front ². He was the first outside investor in Slack ², which was later acquired by Salesforce for $27.7 billion.

At Kleiner Perkins, Hamid has been credited with the firm’s turnaround after a period of underperformance ³. He led Kleiner’s $25 million investment in Rippling’s Series A in 2019 — the largest early-stage investment Kleiner had made at that time ⁴. He also led the Series B investment in Figma ³.

Hamid was named a Kauffman Fellow ⁵ and has been recognized by Gold House ⁶.

Stated Thesis

Hamid describes his role as helping founders see blind spots: “My role is to be the blind-spot monitor — someone who helps founders see things they don’t know they need to encounter” ¹.

On his approach to investing, Hamid has expressed a long-standing preference for workplace productivity tools: over a 15-year period, he has led investments in “Box, Yammer, Intercom, Slack, Figma, Glean, and Coda” — companies that provide tools people use at work ².

Regarding Kleiner Perkins’ investment thesis, Hamid and partner Ilya Fushman have noted that “more than 80% of pitches now involve AI” ⁷, signaling the firm’s heavy exposure to AI-driven companies.

On Figma, Hamid called it “one of those once-in-a-decade kind of companies” and “the venture capitalist’s dream” ³.

On Rippling, Hamid has said: “We had a fundamental belief in Parker as a founder, operator, and visionary” ⁴.

Inferred Thesis

Based on 41 verified active investments and 16 alumni companies from Kleiner Perkins’ website ¹. This represents Hamid’s portfolio since joining Kleiner in 2017, plus key investments from his Social Capital and USVP periods.

Sector distribution (57 verified investments across active and alumni): - Enterprise SaaS / productivity: 16 of 57 (28%) — Slack, Figma, Rippling, Glean, Intercom, Front, Box, Yammer, Coda, Greenhouse, Nooks, Superblocks, Netlify, Mist Systems, OneLogin, Moveworks - AI / machine learning: 14 of 57 (25%) — Anthropic, Glean, Harvey, Hippocratic AI, Ambience, WisdomAI, Chainguard, fal, Keplar, Mirage, Multiply, Traversal, OpenEvidence, Windsurf (acquired by Google) - Healthcare / biotech: 5 of 57 (9%) — Modern Health, Transcarent, Viz.ai, Hippocratic AI, Lotus Health AI - Semiconductor / hardware: 4 of 57 (7%) — Akeana, Alif Semiconductor, Rain, Roadrunner - Consumer / social: 4 of 57 (7%) — Handshake, Kindred, Future, Thrive - Fintech: 3 of 57 (5%) — Imprint, Din Global, Wave Apps - Autonomous / robotics: 2 of 57 (4%) — Waymo, Applied Intuition - Other (infrastructure, security, etc.): 9 of 57 (16%) — Chainguard, Netskope, Reevo, Retym, Parallel, Q, Tajir, Arcade, Castlight Health

Note: Some companies (e.g., Glean) span multiple categories and are counted in their primary category.

Stage distribution: Hamid invests from seed through growth, but his highest-profile investments (Slack, Figma, Rippling, Glean) have been at Series A-B. His signal NFX profile indicates focus on Seed and Series A stages ⁸.

IPO/exit track record: Figma IPO (2025), Slack (acquired by Salesforce, $27.7B), Box (IPO), Castlight Health (IPO), Yammer (acquired by Microsoft), Loom (acquired by Atlassian), Moveworks (acquired by ServiceNow), Mist Systems (acquired by Juniper Networks), Coda (acquired by Grammarly), Windsurf (acquired by Google), Supplyframe (acquired), InstaEDU (acquired) ¹.

Geographic concentration: Heavily concentrated in San Francisco and the Bay Area.

Temporal patterns: Since joining Kleiner in 2017, Hamid’s investments have shifted toward AI. Of 41 active portfolio companies on Kleiner’s website attributed to him, at least 14 are AI-focused, reflecting the broader market shift.

Notable pattern — workplace tools thesis: Hamid’s most successful investments share a common thread: tools that fundamentally change how people work. Slack (messaging), Figma (design), Rippling (HR/IT), Glean (enterprise search), Box (file storage), and Intercom (customer messaging) all fit this pattern. This is arguably the most consistent thematic thread across his 20-year career.

Co-investor patterns: At Kleiner, Hamid frequently co-invests with partner Ilya Fushman. Notable co-investors from portfolio companies include Initialized Capital and Y Combinator (Rippling Series A) ⁴.

What Founders Say

Parker Conrad, co-founder and CEO of Rippling, stated: “I’ve known Mamoon since 2013, and have wanted to work with him for years. I’m excited to have him join Rippling’s board of directors.” He added: “Mamoon and Ilya have played a critical role in building some of the Valley’s iconic SaaS businesses” ⁴. Conrad also characterized Kleiner Perkins under Hamid’s leadership as having “this combination of having this great brand, but having a lot of the energy and the hunger of being a startup firm — nothing was taken for granted” ³.

Dylan Field, co-founder and CEO of Figma, has said of Hamid: “He understood our product immediately when others didn’t. Mamoon treated it like it was the most obvious thing” ³.
