Index Ventures Partner, Martin Mignot: Figma, Scale, Wiz: Inside Index’s Decacorn Factory

Gross margin is frequently a poor indicator of early-stage potential; Index has passed on deals due to low margins but now views this as a mistake, citing Revolut, Snowflake, Deliveroo, and LLM providers as examples where low early margins coexist with massive eventual value.
Price sensitivity in early-stage deals is dismissed as a "mental trap"; the firm never passes on or loses a deal solely due to price if the founder and traction are compelling.
The firm prioritizes "first principle thinking" in founders over industry experience or insider status, valuing the ability to reduce complex problems to simple, defendable insights.
Index operates with a "beginner's mindset" to avoid bias from past successes (e.g., Revolut causing blind spots for other fintechs) or failures (e.g., the music industry bias that led to missing Spotify).
The "Midas List" is viewed as accurate for identifying investors who succeeded 10 years ago but not necessarily current top performers; the firm emphasizes persistent returns through proven teams rather than historical fame alone.
Market timing is recognized as a critical variable, where technological shifts (e.g., smartphone penetration enabling Deliveroo or low token costs enabling AI) can render a concept viable years after it was first conceived.

Index has invested $11.5 billion over 30 years, returning nearly $30 billion while maintaining over $20 billion in current holdings, with returns concentrated in 8–9 companies out of ~400 investments.
The firm rejects the binary of "mega-funds" vs. "tiny boutiques," advocating for a "third way" requiring minimum scale (current funds: $300M Seed, $800M Venture, $1.5B Growth) to support founders across the entire lifecycle without becoming a fee-accumulating giant.
Decision-making uses a "qualified majority" voting system where deals pass if the average vote is above 6/10, requiring a clear consensus against "middle-of-the-road" (4–6) votes.
The firm maintains a global approach rather than a regional one, investing ~50% in Europe and 50% in the US to fight for the "global maximum" rather than local winners.
Ownership targets remain double-digit at exit; while 20% was a historical bar, the focus has shifted to securing meaningful ownership in category leaders early to maximize impact returns.
Liquidity is executed via systematic quarterly sales post-IPO over three years to avoid the pitfall of trying to time the market at the top, despite acknowledging the possibility of selling too early in specific cases like Robinhood.

Revolut: A controversial early investment due to negative gross margins and low US familiarity; the firm attributes success to the founder's first-principles approach (FX as a hook for a global money app) and the strategic advantage of EU passporting.
Figma: An example of high-conviction patience where the firm supported founder Dylan Field for years before product launch, demonstrating the value of "unparalleled conviction" despite a lack of initial traction.
AI/LLM Sector: The firm is invested in Cohere (seed) and Mistral; they anticipate lower pure multiples due to dilution but expect high absolute returns due to massive outcome scales and speed of growth.
European Sovereignty: Martin argues for a market case for European LLM providers driven by geopolitical sovereignty and the need for localized customization by government and quasi-government entities.
Talent War: Startups compete with tech giants via ESOPs and equity stories rather than cash compensation; the firm acknowledges the intensity of the current war for talent but views high-work intensity (7 days/week) as a necessary standard for hyper-growth.

The venture industry is institutionalizing with larger funds, but Index believes this does not necessitate a shift to "low margin" operations; they argue scale is needed to serve founders, but "giga-size" is not required for early-stage impact.
Revenue quality (stickiness, cohort analysis) is becoming more critical than top-line growth numbers, particularly in AI where "project-based" revenue may indicate weak product-market fit.
The concentration of value is not a new phenomenon; Index notes that historically, a small number of winners have generated the majority of returns, a trend expected to continue in AI.
Government intervention in AI is viewed as necessary for critical infrastructure, with a preference for governments acting as "customers" to support local providers rather than solely as investors.
The firm observes that "time to copy" for competitors is shrinking, increasing the premium on execution and defensibility beyond just the initial unique insight.

Martin rejects the notion of venture as a "career," defining it instead as a "calling" that requires a 10–15 year commitment focused on supporting founders rather than external rewards or status.
The "best founders" are those who leverage unique insights from experience or sheer intelligence to break down complex problems, rather than those with industry naivety or insider status.
High team turnover is acknowledged as an industry norm, but Index emphasizes the stability of its partner and strategist ranks (many with 10+ years tenure) as a key differentiator for trust and competency.
Martin's personal ambition is not to lead the firm (which operates as an equal partnership without a CEO), but to continue investing in exceptional founders as long as possible, driven by the "human adventure" of using technology to alleviate suffering.
Family life, particularly fatherhood, has made him more relativistic about work stress and less tolerant of wasted time, reinforcing the importance of long-term thinking and prioritization.
