Lessons from Aileen Lee

Aileen Lee coined the term "unicorn" in 2013 to describe rare startup valuations. She later founded Cowboy Ventures and co-founded All Raise, where her investing centers on capital efficiency and structural diversity. This collection outlines her advice on early-stage venture capital, evaluating markets, and the actual mechanics of building a billion-dollar company.

Part 1: The "Unicorn" Phenomenon

  1. On Originating the Term: "Yes we know the term 'unicorn' is not perfect. Unicorns apparently don't exist, and these companies do. But we like the term because to us, it means something extremely rare, and magical." — Source: [TechCrunch]
  2. On Misplaced Priorities: "Some people took unicorn status as the goal, rather than as a milestone." — Source: [Inc.]
  3. On Rejected Alternatives: "I tried 'home run,' 'megahit,' 'Godzilla.' Then I tried 'unicorn,' which didn't sound so business-school douchey." — Source: [Inc.]
  4. On Evolving Realities: The number of U.S. unicorns expanded from 39 in 2013 to 532 by early 2024, shifting the landscape from a mythical rarity to a crowded herd. — Source: [Forbes]
  5. On "Zombiecorns": Many companies from the zero-interest-rate era have become "zombiecorns," meaning startups with billion-dollar valuations that are stagnant and unable to raise new capital. — Source: [Forbes]
  6. On "Unicorpses": Former high-flyers that fail completely serve as a warning that valuation does not equal permanent viability. — Source: [Forbes]
  7. On Artificial Milestones: "Papercorns" are companies that optimize solely for valuation metrics over underlying, sustainable business fundamentals. — Source: [This Week in Startups]
  8. On Inflated Valuations: When funds have an incentive to write bigger checks at higher valuations, it creates a dynamic that holds everything up and ultimately decreases returns for the industry. — Source: [Forbes]
  9. On Early Valuations: Reaching a billion-dollar valuation prematurely can act as a curse if the startup lacks the operational strength to support it during a market downturn. — Source: [Cowboy Ventures]
  10. On Market Discipline: Operating in a disciplined fundraising environment requires founders to prioritize capital efficiency over the growth-at-all-costs mindset. — Source: [Bloomberg Technology]

Part 2: The Data Behind the Magic

  1. On the "Dropout" Myth: The average age of founders who built the original billion-dollar companies was 34, proving that industry experience often outperforms youthful energy. — Source: [TechCrunch]
  2. On Solo Founders: The vast majority of successful billion-dollar companies are started by co-founding teams who have a prior working relationship, rather than solo operators. — Source: [Cowboy Ventures]
  3. On B2B Efficiency: Enterprise-oriented startups are historically 2.4 times more capital efficient than their consumer-focused counterparts. — Source: [TechCrunch]
  4. On "Mundane" Tech: The most enduring value often lies in applying technology to unsexy industries like healthcare, accounting, and legacy professional services. — Source: [StrictlyVC]
  5. On Systematic Analysis: Venture capital must evolve past gut instinct and pattern matching toward a rigorous, data-driven understanding of what actually builds enterprise value. — Source: [Stanford ETL]
  6. On AI Services: AI-powered professional services represent a multi-trillion-dollar opportunity if founders focus on practical, workflow-integrated solutions. — Source: [StrictlyVC]
  7. On Vendor Consolidation: Enterprise customers currently want best-of-suite software rather than best-of-breed tools to reduce the complexity of their technology stacks. — Source: [StrictlyVC]
  8. On Early Warning Signs: Tracking Experimental Revenue Run Rate is crucial during AI integration, as the core challenge is converting initial pilot experiments into recurring revenue. — Source: [StrictlyVC]
  9. On Raising Too Early: Modern unicorns often raise too much capital too early, sacrificing the lean efficiency that characterized the most successful companies of the early 2010s. — Source: [Startup Grind]
  10. On Historical Benchmarks: Only 39 companies fit the original criteria in 2013, establishing a baseline for what true outlier capital efficiency looked like before the zero-interest-rate era. — Source: [TechCrunch]

  2. On Incremental Progress: While female-founded unicorns increased to 14% by 2024, the venture ecosystem remains far from achieving genuine parity. — Source: [Forbes]
  3. On the Meritocracy Myth: "Generally, the tech industry had posed as a meritocracy, but women, minorities, and people from nontraditional backgrounds haven't had a fair shake." — Source: [MIT News]
  4. On Sparking a Movement: A single email sent to a group of female VC partners in 2017 to brainstorm structural improvements eventually led to the founding of All Raise. — Source: [Medium]
  5. On the Mission: "Our mission is simple. To accelerate the success of female funders and founders." — Source: [All Raise]
  6. On Motivating Change: "We try and motivate by greed, not by fear. Making people feel bad for mistakes that we've made in the past is not going to get people to dig harder and faster." — Source: [Forbes]
  7. On the "Pipeline" Excuse: Noting that women receive over half the engineering degrees at top schools, she remarked, "Stick that in your 'pipeline problem' and smoke it." — Source: [All Raise]

  1. On Prioritization: At the seed stage, the specific market and the people involved are infinitely more critical than the initial product, which will inevitably pivot. — Source: [Startup Grind]
  2. On Recruiting Focus: Early-stage founders must dedicate at least 50% of their time to recruiting, as the first ten hires will define the company's culture and trajectory. — Source: [Cowboy Ventures]
  3. On the Core Insight: Success requires a deep personal connection to a problem and a "mousetrap" that is significantly better, not just marginally better, than existing alternatives. — Source: [Business Insider]

  3. On Resilience: "Getting your ass kicked is a precursor to kicking ass." — Source: [This Week in Startups]

  7. On Blindly Following: Both investors and founders must actively look for new trails rather than merely chasing the latest hype cycle or consensus opinion. — Source: [Cowboy Ventures]
  8. On Starting Up: "Being a founder" should never be the objective. Building a company only makes sense when compelled by an undeniable problem. — Source: [Business Insider]

  7. On Modern Teamwork: A core focus is "Modern Teamwork Software," building elegant solutions for historically underserved and unsexy categories like HR and internal operations. — Source: [Medium]
  8. On The First Call: A seed investor's true mandate is to become the "first call" partner a founder trusts enough to rely on when things go catastrophically wrong. — Source: [Cowboy Ventures]
  9. On Founder Secrets: The best founders possess a fundamental secret about how consumer or enterprise behavior is shifting, paired with the operational grit to act on it. — Source: [Cowboy Ventures]

Part 7: On Diversity, Inclusion, and All Raise

Part 8: The Journey from Gap to Kleiner to Cowboy

  1. On Leaving Prestige: "It was scary. It was like leaving the Harvard of venture capital. I was wondering after leaving, 'Would anyone still talk to me?'" — Source: [Business Insider]
