Marc Andreessen
Co-founder, Andreessen Horowitz (a16z)
WHO THEY ARE — Co-creator of Mosaic and Netscape, the early web browsers that helped popularize the internet. Co-founded Andreessen Horowitz in 2009 with Ben Horowitz.
KEY IDEA — Best known publicly for his 2011 Wall Street Journal essay "Why Software Is Eating the World," arguing software would transform industries well beyond traditional tech (see Investor Library entry above).
FOUNDER LESSON — Look for industries not yet "eaten" by software as a lens for identifying "why now" — the thesis rewards founders who can identify which traditional sectors are only just becoming ready for software-driven change.

Paul Graham
Co-founder, Y Combinator
WHO THEY ARE — Programmer, essayist, and co-founder of Y Combinator, the startup accelerator that popularized the batch-based accelerator model and helped launch companies including Airbnb, Stripe, and Dropbox as portfolio companies.
KEY IDEA — Widely known for a large body of public essays on startups, most notably "How to Get Startup Ideas" — the idea that great startup ideas are noticed by people close to a real problem, not invented through abstract brainstorming.
CAREER LESSON — Graham's essays are frequently cited in VC interviews and case discussions — reading his public essay archive is one of the most accessible ways to absorb foundational startup-evaluation thinking before ever working at a fund.

Fred Wilson
Co-founder, Union Square Ventures
WHO THEY ARE — Venture capitalist since 1987, previously co-founded Flatiron Partners (1996) before co-founding Union Square Ventures (USV) in 2003 with Brad Burnham. USV's publicly known investments have included Twitter, Etsy, Tumblr, Kickstarter, and Coinbase.
KEY IDEA — USV's publicly stated investment thesis centers on backing large networks of engaged users — businesses that create new behaviors or broaden access to information, capital, or wellbeing. Wilson has written daily on his blog, AVC, since USV's founding in 2003, making his investment thinking unusually public for the industry.
INVESTOR LESSON — Wilson's long-running public writing is itself a case study in how transparency can function as a deal-sourcing strategy — founders who've followed his thinking for years often reach out to him directly, a very different dynamic from cold, one-off pitches.

Bill Gurley
Former General Partner, Benchmark
WHO THEY ARE — Joined Benchmark Capital in 1999 after previously working at Hummer Winblad Venture Partners, where he was known for early marketplace investing (including eBay). At Benchmark, his publicly known investments included Uber, Zillow, OpenTable, and GrubHub.
KEY IDEA — Widely known for detailed public writing on marketplace business models through his blog, "Above the Crowd," analyzing factors like buyer/seller fragmentation, whether a marketplace sits in the actual payment flow, and rake (take-rate) sustainability. Also publicly known for a 2015 critique of high startup burn rates and "growth at all costs" thinking.
FOUNDER LESSON — Gurley's marketplace framework is a genuinely practical checklist for any founder building a two-sided platform — his emphasis on sustainable unit economics over pure growth is a recurring, publicly documented theme across his writing.

Naval Ravikant
Co-founder, AngelList
WHO THEY ARE — Co-founder and former CEO of AngelList, a platform connecting startups with angel investors, and an active angel investor himself in companies including Twitter and Uber.
KEY IDEA — Widely known for his 2019 Twitter thread "How to Get Rich (Without Getting Lucky)," distinguishing wealth (assets that earn independent of your time) from money and status, and arguing wealth is built through equity ownership, specific hard-to-train knowledge, and leverage.
CAREER LESSON — His framing of equity versus salary is a useful lens for evaluating any startup or VC career opportunity — how much of the upside is ownership versus fixed pay.

Ben Horowitz
Co-founder, Andreessen Horowitz (a16z)
WHO THEY ARE — Co-founder and general partner of a16z alongside Marc Andreessen. Previously co-founded and served as CEO of Loudcloud/Opsware, an enterprise software company acquired by Hewlett-Packard in 2007 for $1.6 billion.
KEY IDEA — Author of "The Hard Thing About Hard Things" (2014), a candid account of the operational and psychological difficulty of running a company, drawing directly on his own experience navigating near-failure at Loudcloud/Opsware.
FOUNDER LESSON — His writing is notable for rejecting easy formulas — emphasizing that hard decisions (layoffs, demoting a friend, managing your own psychology under pressure) rarely have a clean playbook.

John Doerr
Chairman, Kleiner Perkins
WHO THEY ARE — Joined Kleiner Perkins in 1980; an original investor and board member at both Google and Amazon during their early stages.
KEY IDEA — Introduced OKRs (Objectives and Key Results) — a goal-setting framework he learned from Andy Grove at Intel — to Google in 1999, and later popularized the system broadly through his 2018 book "Measure What Matters."
FOUNDER LESSON — OKRs are now used well beyond VC-backed startups — understanding the framework (objectives = what, key results = how measured) is practically useful for any team trying to set and track priorities transparently.

Peter Thiel
Co-founder, Founders Fund
WHO THEY ARE — Co-founder and former CEO of PayPal (acquired by eBay in 2002 for $1.5B); made the first outside investment in Facebook in 2004 (~10% for $500,000); co-founded Palantir Technologies; co-founded venture firm Founders Fund in 2005.
KEY IDEA — Author of "Zero to One" (2014, with Blake Masters), arguing the most valuable companies create genuinely new things rather than incrementally competing in existing markets, and that real competition is often a sign a company won't capture enough value from a good idea.
FOUNDER LESSON — Be ready to articulate genuine differentiation, not just relative advantage over competitors — this framework specifically probes whether an idea can become a durable, defensible business.

Aileen Lee
Founder & Managing Partner, Cowboy Ventures
WHO THEY ARE — Spent over a decade at Kleiner Perkins before founding Cowboy Ventures in 2012, a seed-stage firm. Co-founder of All Raise, a nonprofit supporting women in the venture-backed tech ecosystem.
KEY IDEA — Coined the term "unicorn" in a November 2013 TechCrunch article analyzing US venture-backed companies that reached $1B+ valuations — at the time finding only 39 such companies. Her 2024 ten-year follow-up found the count had grown past 1,200, with many becoming "zombiecorns" unable to raise or exit at their peak valuation.
INVESTOR LESSON — Her follow-up research is a useful, honest reminder that a headline valuation is not the same as a durable, fundable, or exitable business.

Brad Feld
Co-founder, Foundry Group & Techstars
WHO THEY ARE — Co-founded Foundry Group in 2007 (a deliberately flat, four-equal-partner firm) and co-founded Techstars, one of the best-known global startup accelerators. Early investor in Zynga, Fitbit, and MakerBot.
KEY IDEA — Co-author (with Jason Mendelson) of "Venture Deals" (2011), a detailed, practitioner-written guide to venture term sheets aimed explicitly at helping founders negotiate confidently. Also a long-running blogger at Feld Thoughts since 2004.
FOUNDER LESSON — "Venture Deals" remains one of the most commonly recommended resources for first-time founders trying to understand deal mechanics before their first term sheet negotiation.

Mary Meeker
Co-founder, BOND (formerly Kleiner Perkins)
WHO THEY ARE — A former Morgan Stanley analyst who joined Kleiner Perkins, leading its growth practice from roughly 2010-2019 and backing companies including Facebook, Spotify, and Ring. Left in 2018-2019 to found BOND Capital, raising a large debut growth fund; her Canva investment (2019) became one of her most notable bets.
KEY IDEA — Creator of the annual "Internet Trends" report, first produced in 1995, which became one of the most widely watched technology presentations for over two decades — distilling data on internet adoption, mobile growth, and platform shifts.
CAREER LESSON — Her rigorous, data-first approach to market analysis is a useful model for anyone practicing the kind of market sizing and trend synthesis expected in a strong investment memo.

Reid Hoffman
Partner, Greylock Partners
WHO THEY ARE — Co-founded LinkedIn in 2003 and led it through its first years as CEO; previously executive vice president and a founding board member at PayPal. Joined Greylock Partners in 2009 as a partner focused on early-stage consumer technology investing.
KEY IDEA — Popularized "blitzscaling" — prioritizing speed over efficiency to establish network effects before competitors can — co-authoring the book "Blitzscaling" with Chris Yeh. Also co-authored "The Start-up of You" and "The Alliance," and hosts the "Masters of Scale" podcast.
FOUNDER LESSON — His own clarification is important context: blitzscaling is a deliberate, temporary trade-off of efficiency for speed under specific competitive conditions — not a universal growth strategy every startup should default to.

Chris Dixon
General Partner, Andreessen Horowitz; Founder, a16z crypto
WHO THEY ARE — Joined Andreessen Horowitz as a general partner in 2012-2013, after previously co-founding and leading two startups — SiteAdvisor (acquired by McAfee, 2006) and Hunch (acquired by eBay, 2011). Founded and leads a16z's dedicated crypto investing practice, launched in 2018.
KEY IDEA — Author of "Read Write Own: Building the Next Era of the Internet" (2024), arguing blockchain-based ownership represents a genuine structural shift in how the internet is built and owned, distinct from prior web eras. Also known for an influential personal blog (cdixon.org) throughout the 2010s on startup strategy and technology trends, independent of the crypto-specific work.
INVESTOR LESSON — His operating background (two real startups, one acquisition each) is a reminder that some of the most influential investor writing comes from people who built and sold companies themselves before investing full-time.
