Not all VC sectors deliver equal returns. Here’s what the 2025 data shows about which categories actually generate the best ROI.

Headline 2025 sector data

• AI — 65.4% of U.S. VC deal value, 39.4% of deal count (Pitchbook-NVCA Q4 2025).
• IT + Healthcare + Industrials — 85% of invested capital in U.S. VC index (Cambridge Associates H1 2025).
• Life Sciences + Biotech — consistent secondary share, growing with AI drug discovery.
• Climate tech — 4-6% of U.S. VC, up from under 2% pre-2020.
• Fintech — softer post-2022, recovering in 2025 led by AI-native fintech.

Historical sector return observations

Enterprise software (B2B SaaS)

• Why it wins: High gross margins (75–90%), predictable retention, recurring revenue.
• IRR pattern: Top-quartile funds in enterprise SaaS generate 20–30% net IRR historically.
• Examples: MongoDB, Datadog, Snowflake — fund-returners that drove top decile outcomes.

Consumer internet / marketplaces

• Why variable: Winner-take-all dynamics — power-law outcomes.
• IRR pattern: A single winner (Facebook, Airbnb, Uber) returns an entire fund.
• Risk: Most consumer bets write to zero; sector-level medians are weaker than enterprise SaaS.

Biotech / life sciences

• Why volatile: Binary clinical outcomes drive large wins and losses.
• IRR pattern: High-variance but potential for top-decile outcomes (Moderna, Loxo Oncology).
• Cycle dependency: Public market receptivity drives exit timing.

Fintech

• Why solid: Recurring revenue, sticky customers, regulatory moats.
• IRR pattern: Top-quartile strong but narrower dispersion than consumer.
• 2025 catalyst: AI-native fintech infrastructure is growing fast (Ramp’s trajectory).

AI foundation models

• Why uncertain: Huge capital requirements, long time to revenue, regulatory risk.
• IRR pattern: Too early to fully measure; 2022+ vintage foundation model bets are tracking well on paper but DPI lags.

Key insight from Cambridge Associates H1 2025

• Smaller funds generally outperform larger funds: The top-decile $100–300M fund often beats the $1B+ fund in IRR, because concentration of winners in a smaller base amplifies returns.
• 2021 vintage funds struggling: Median TVPI barely above 1.0x; 75th percentile IRR 5.9%.
• 2022–2023 vintages performing better: Entry valuations post-correction are healthier.

What actually wins in VC returns

1. Stage discipline: A fund that stays in its stage through cycles beats a firm that drifts.
2. Reserve discipline: Disciplined follow-on capital in winners multiplies fund-level DPI.
3. Sector specialization: Specialized funds often beat generalists in applied categories (health, fintech, cyber).
4. Portfolio construction: Power-law math requires betting small on many, large on winners.

NYC-specific ROI implications

1. B2B SaaS and fintech remain the most consistent NYC winners.
2. Consumer and marketplaces can produce outsized wins but require Bay Area-scale network effects.
3. Applied AI in finance and health is NYC’s highest-conviction 2026 category.

Practical takeaway

• Founders: Sector-specialist investors often deliver better post-money support than generalists.
• Investors: Durable returns come from sector discipline + reserve discipline, not deal count.
• LPs: Diversify across sectors AND stages; single-theme concentration is a top risk.
