Frequently Asked Questions

How much did US startups raise in 2025 month by month?

US startup funding in 2025 showed a strong recovery trajectory after the 2022-2023 correction. AI dominated deal flow throughout the year, with Q1 2025 seeing approximately $45B in venture investment, Q2 accelerating to $58B, and H2 continuing the upward trend as interest rate cuts improved LP sentiment. Monthly highlights included OpenAI’s $40B raise in March 2025, which was the largest single venture round in history, alongside strong biotech, defence tech, and climate tech deal flow.

Which sectors led US startup funding in 2025?

AI and machine learning dominated US startup funding in 2025, accounting for over 40% of total venture dollars. Biotech and life sciences maintained their traditional strength, particularly companies applying AI to drug discovery. Defence technology saw a record year driven by increased government procurement and geopolitical tensions. Climate tech and clean energy benefited from ongoing IRA incentives, while fintech saw a selective recovery in payments and embedded finance.

What is β€˜Space Cloud’ and how does it fit into the US startup ecosystem?

Space Cloud refers to the emerging category of companies building cloud computing infrastructure and services that operate in orbit β€” satellites providing computing, storage, and AI processing capability in space rather than earth-based data centres. US startups in this category include companies like Axiom Space, Vast, and several stealth ventures targeting applications including remote sensing processing, space-based AI training, and low-latency satellite edge computing for areas underserved by terrestrial connectivity.

How did US startup valuations change in 2025 compared to 2021-2022?

US startup valuations in 2025 remained well below the peak multiples of 2021 in most sectors, with the exception of frontier AI companies that commanded premium valuations reflecting intense investor competition for access. Median Series A, B, and C valuations were 30-40% below 2021 peaks, with investors requiring more revenue traction and clearer paths to profitability than during the zero-interest-rate era. The valuation compression created better entry points for investors while tightening the funding environment for all but the strongest companies.

Which US cities outside San Francisco saw the most startup activity in 2025?

New York City continued to challenge San Francisco as the #2 US startup hub, with particularly strong deal flow in AI, fintech, media tech, and health tech. Austin and Miami maintained their post-pandemic momentum as founder-friendly alternatives to coastal hubs. Boston remained dominant in biotech and life sciences. Los Angeles showed strength in consumer tech, creator economy, and climate tech. Emerging regional hubs including Atlanta, Chicago, and Denver also saw increased deal activity.

What were the biggest US startup exits in 2025?

Major US startup exits in 2025 included a wave of AI company secondaries and late-stage raises at valuations that functioned as de facto exits for early investors. On the IPO front, the market remained selective but more active than 2023-2024, with several high-profile listings in defence tech, biotech, and enterprise software. M&A activity by large tech companies β€” particularly AI acqui-hires and strategic technology acquisitions β€” provided significant returns to early investors across the ecosystem.
