Y Combinator often backs startups that duplicate other YC companies, data shows
Y Combinator is being criticized for repeatedly funding startups that resemble or directly compete with previous YC-backed companies, raising questions about conflicts of interest and originality in its portfolio. Many argue this is a rational venture strategy—YC backs “founders, not ideas,” spreads risk across multiple bets in the same market, and expects teams to pivot—while others worry it encourages copycats, concentrates power, and produces little real-world value. The debate highlights broader concerns about modern VC behavior, market validation, and whether accelerator-scale investing still benefits founders and the wider economy.
YC’s Investment Strategy
- Many see YC’s behavior as rational VC portfolio construction: make many small, early bets, including multiple “horses in the same race,” to hedge idea, execution, timing, and luck risk.
- At the current scale (hundreds of companies per batch, ~5,000 overall), avoiding overlap is viewed as impractical.
- Some frame YC as “spray and pray” plus brand-signaling: they filter out obvious losers, then rely on batch support and YC’s halo to increase odds.
Duplicate Startups & Competition
- Commenters note long-standing examples (e.g., two file-sync companies, multiple compression or podcasting startups in adjacent batches).
- Overlap can be by product, geography, or niche (e.g., POS for bars vs coffee shops).
- Several argue that superficially identical products can still target different segments, routes to market, or problem scales, so “duplication” is oversimplified.
Ideas vs Execution vs Founders
- Strong consensus that ideas are cheap; execution, team quality, and persistence matter far more.
- YC is repeatedly described as “backing founders, not ideas,” even encouraging teams to form first and choose ideas later.
- Others push back, saying it’s not actually easy to pick “the right people,” and suspect selection biases toward elite schools and wealth.
Conflicts of Interest and Ethics
- Some see funding direct competitors as an “obvious conflict of interest” and potentially corrosive to trust.
- Others argue conflicts aren’t inherently bad; outcomes matter, and diversification is normal in investing.
- Comparison is drawn to firms that copy or undercut partners, with the distinction that YC doesn’t operate products itself.
Impact on Founders, Employees, Ecosystem
- From founders’ perspective, it can feel risky: fear of idea leakage and being undercut by a “YC twin” perceived as the favored child.
- Employees of “loser” startups may suffer when similar, better-backed peers win; emotional and career costs are highlighted.
- Some argue clustering can still benefit customers and workers: validates markets, creates talent mobility, and reduces perceived adoption risk.
Pivots, Market Validation, and Clustering
- YC’s tolerance for pivots is seen as a key reason overlap emerges mid-batch; teams pivot toward known, fundable problem spaces under time pressure.
- Multiple competitors are said to validate a market: often the main enemy is non-adoption (e.g., Excel), not the other startup.
- Several note that popular ideas and tech waves (blockchain → LLMs, AI tools, devtools) naturally create dense clusters, with or without YC.
Broader VC / Tech Context
- Some commenters view this as standard VC behavior, not news; others see it as emblematic of a “musical chairs” ecosystem with weak real-world value.
- There’s disagreement over how competent VCs are at picking winners versus functioning as quasi-index funds.
- A minority frames YC’s pattern as part of larger concerns about inequality, nepotism, and weakened social/ethical norms in tech and finance.
