Venture Capital in Biotech: A Look at Recent Years

Biotech venture capital funding has seen dramatic shifts over the past few years, influenced by macroeconomic factors, regulatory changes, and scientific breakthroughs. The sector experienced record highs in investment during the pandemic, as investors poured capital into drug discovery, vaccine development, and emerging biotech innovations. However, funding has since cooled, reflecting broader economic uncertainties, rising interest rates, and shifting investor priorities.

In 2020 and 2021, biotech funding reached unprecedented levels. Investors were eager to back companies involved in pandemic-related therapeutics, diagnostics, and vaccine platforms. The boom extended beyond COVID-19 solutions, fueling investment in next-generation therapies such as gene editing, cell therapies, and AI-driven drug discovery. The IPO market was also thriving, with biotech companies raising billions through public offerings, often at high valuations.

By 2022 and 2023, the landscape changed significantly. Biotech funding rounds became more selective, with venture capitalists focusing on startups with de-risked assets and clear commercial pathways. Rising interest rates and concerns over biotech profitability led to fewer late-stage deals and a decline in biotech IPOs. Many companies that went public in the prior boom saw their valuations fall, prompting investors to rethink their approach to biotech exits.

Despite these challenges, biotech venture capital funding remains strong in specific areas. Oncology, gene therapy, rare diseases, and AI-driven drug development continue to attract investment. Additionally, big pharma partnerships are playing an increasing role in financing biotech startups, helping companies bridge funding gaps and advance promising therapies.

As the biotech sector moves forward, startups must adapt to investor expectations, demonstrating not only cutting-edge science but also clear commercialization strategies. With a more cautious investment environment, securing funding requires a combination of strong clinical data, well-defined milestones, and strategic partnerships.

Partnerships help startups reduce financial risk, accelerate development, and gain access to big pharma’s expertise, regulatory networks, and commercial infrastructure. These deals often include milestone-based funding, where startups receive capital as they hit clinical and regulatory benchmarks.

For biotech startups, aligning with investor priorities and demonstrating strong scientific validation, clear clinical pathways, and commercialization potential is critical for securing funding in today’s evolving landscape.

Early-Stage vs. Late-Stage Biotech Funding—What’s Changing?

The biotech funding landscape is shifting, with early-stage and late-stage startups facing different challenges and opportunities. While Series A funding remains active, late-stage funding rounds have become more selective, forcing startups to demonstrate stronger clinical and financial milestones. Investors are increasingly focused on risk mitigation, impacting how capital is allocated across different stages of biotech development.

Early-stage biotech: Selective but steady Series A funding

Despite economic uncertainty, early-stage biotech funding has remained relatively stable, particularly for companies working in high-growth therapeutic areas like oncology, rare diseases, and gene therapy. Investors recognize that groundbreaking science often starts at the preclinical stage, and they continue to fund promising startups that:

  • Have strong scientific validation: Early-stage VCs prioritize startups with well-supported preclinical data, clear differentiation from existing treatments, and robust intellectual property (IP) portfolios.
  • Focus on high-impact therapeutic areas: Startups working in high-priority areas like gene therapy, precision medicine, and AI-driven drug discovery are more likely to secure early-stage funding.
  • Leverage non-dilutive funding sources: Many early-stage biotech companies are supplementing venture capital with government grants, partnerships, and academic collaborations to extend their runway before raising larger rounds.

While Series A funding is still available, startups must be prepared for longer due diligence processes, more scrutiny over their clinical strategy, and increased pressure to show a viable path toward commercialization.

Late-stage biotech: Tighter funding rounds and higher expectations

Late-stage biotech startups—particularly those in Series B and beyond—face a more cautious funding environment. Many investors are pulling back from large-scale growth funding due to concerns about biotech valuations, profitability, and exit opportunities. This shift has led to:

  • Fewer late-stage funding rounds: Many biotech companies that raised large Series A rounds now struggle to secure follow-on funding without significant clinical progress.
  • Increased focus on clinical milestones: Investors expect startups to demonstrate clear clinical efficacy, strong regulatory progress, and a well-defined market strategy before committing capital.
  • More pressure on profitability and scalability: Unlike in previous years, late-stage investors are emphasizing commercial viability, not just scientific potential. Startups must show how they will scale production, gain market access, and achieve long-term financial sustainability.

With fewer biotech IPOs and a cooling public market, late-stage startups that might have gone public in a different funding environment are now looking for alternative strategies. Many are pursuing M&A deals, strategic partnerships, or structured financing options to stay afloat.

What this means for biotech startups

Biotech startups at all stages must adapt to this changing landscape by:

  • Aligning their fundraising strategy with investor expectations—early-stage startups need to show strong preclinical data, while late-stage companies must prove clinical and commercial viability.
  • Building strategic partnerships—collaborations with big pharma, academic institutions, and non-dilutive funding sources can extend cash runways and de-risk development.
  • Focusing on milestone-driven funding—whether raising a Series A or late-stage round, startups must present a clear roadmap with achievable clinical and regulatory milestones.

As the funding landscape evolves, biotech founders must approach fundraising with a long-term strategy, ensuring they have both the capital and partnerships needed to reach key development milestones.

The IPO Market & Exit Strategies—What’s Next?

For years, biotech startups viewed initial public offerings (IPOs) as the ultimate funding milestone, providing capital for late-stage clinical trials and commercialization. However, the biotech IPO market has cooled significantly since its peak in 2020-2021. Rising interest rates, investor caution, and underperforming public biotech stocks have made IPOs a less reliable exit strategy. As a result, many biotech startups are exploring alternative exit pathways, including mergers, acquisitions, and structured financing.

Biotech IPOs: A slower recovery in public offerings

The biotech sector saw record highs in IPOs during 2020 and 2021, fueled by pandemic-driven investor enthusiasm and a low-interest-rate environment. Many startups went public at high valuations, sometimes without late-stage clinical data. However, as market conditions tightened in 2022 and 2023, the IPO window narrowed dramatically, and many newly public biotech companies struggled to maintain their valuations.

Recent trends suggest that while the IPO market is not dead, it has become more selective. Investors are looking for biotech companies that:

  • Have late-stage clinical data—early-stage companies without Phase 2 or Phase 3 results face significant IPO challenges.
  • Demonstrate commercial viability—public market investors are wary of biotech startups with uncertain revenue potential and long development timelines.
  • Are targeting high-demand therapeutic areas—companies working in oncology, gene therapy, and cell therapies have a better chance of attracting IPO interest.

While some high-profile biotech IPOs have succeeded, the market is unlikely to return to its previous peak anytime soon. Instead, many biotech startups are delaying their IPOs or reconsidering whether going public is the best option.

Mergers, acquisitions, and alternative exit strategies

With IPOs less accessible, M&A activity is increasing, as big pharma seeks to acquire promising biotech startups. Large pharmaceutical companies are under pressure to replenish their drug pipelines, especially as patents expire on blockbuster drugs. This has created opportunities for biotech startups with high-value assets to secure strong exits through acquisitions.

Other alternative financing and exit strategies include:

  • Structured financing—some late-stage biotech companies are raising capital through venture debt, royalty financing, or milestone-based funding deals to delay IPOs until market conditions improve.
  • Strategic partnerships—instead of selling outright, biotech startups are licensing technologies or forming partnerships with big pharma, providing immediate capital while retaining long-term upside.
  • Reverse mergers and SPACs—while less common than during the 2021 boom, some biotechs are using reverse mergers or special purpose acquisition companies (SPACs) as alternative paths to public markets.

What this means for biotech startups

The shift away from easy IPOs means biotech founders need to plan their exit strategies early. Instead of relying solely on a public offering, startups should:

  • Position themselves for acquisition by big pharma—demonstrating strong clinical data, intellectual property value, and commercial potential can attract M&A interest.
  • Explore strategic partnerships—partnering with pharmaceutical companies can provide capital, resources, and market validation.
  • Be financially disciplined—startups must ensure they have enough funding to reach critical milestones, as investors and acquirers are prioritizing de-risked biotech companies.

While the IPO market remains challenging, biotech startups with breakthrough therapies, strong clinical data, and clear commercialization strategies still have multiple pathways to secure funding and long-term success.
