Insights

Life sciences ecosystem analyst

Lilly expands its Gateway Labs footprint to Philadelphia, adding 44,000 sq ft of partnered lab capacity and ecosystem support on Nov. 19, 2025.

Eli Lilly will open a new Lilly Gateway Labs site occupying 44,000 square feet at 2300 Market in Center City, operated with Breakthrough Properties. The Gateway Labs model pairs dedicated wet lab infrastructure with strategic scientific engagement and is already present in Boston, South San Francisco, and San Diego; since the first site opened in 2019 resident companies have collectively raised $3 billion and advanced over 50 therapeutic programs.

The announcement describes a mechanism that supplies both physical capacity and hands-on scientific partnership to early-stage companies, which can accelerate translational work when combined with nearby academic medical centers. Dependencies and risks are explicit in the text: success depends on attracting a select cohort of resident biotechs and effective collaboration with local ecosystem partners; outcomes rest on the undisclosed quality of resident programs and future capital flows.

Concrete items to watch include occupancy and resident selection at the new Center City site, any disclosed metrics on program advancement from these residents, and follow-up milestones tied to Gateway Labs or Catalyze360 over the next 12–24 months. The partnership with Breakthrough Properties, the stated footprint, and the cited historical fundraising ($3 billion) provide measurable baseline facts against which future progress can be compared.

Gateway Labs model provides lab space and tailored scientific engagement to fuel next-generation medicines

New Center City site, in partnership with Breakthrough Properties, will host a select group of early-stage biotech companies

INDIANAPOLIS, Nov. 19, 2025 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced plans to open a new Lilly Gateway Labs (LGL) site in Philadelphia, bringing its distinctive model of scientific partnership to a city known for shaping the future of medicine.

The new Gateway Labs site will occupy 44,000 square feet of 2300 Market, a life sciences facility in Center City newly developed and operated by Breakthrough Properties. Biotechs based in the site will have access to dedicated, fully equipped wet lab facilities alongside the strategic scientific engagement that has been the hallmark of the Gateway Labs approach.  

"Philadelphia has long led biotech innovation, from early vaccine development to pioneering gene therapy and CAR-T treatments and discovering new approaches to Alzheimer's disease. Today's local biotech scene builds on that legacy with founders tackling medicine's toughest challenges," said Julie Gilmore, Ph.D., vice president, and global head of Lilly Gateway Labs and Catalyze360 Portfolio Management. "Access to top-notch lab infrastructure is essential, but success for early-stage companies also requires experienced thought partners who understand the science and can help navigate the challenging journey from discovery through early clinical development."

Lilly's expanded Philadelphia presence underscores its strategy of establishing Gateway Labs sites in communities where research excellence and entrepreneurial ambition converge. Anchored by leading academic medical centers and serving a diverse patient population, Philadelphia has evolved as an upper tier life sciences innovation hub where foundational research rapidly advances toward clinical application. With the addition of Philadelphia, Gateway's U.S. footprint now includes four geographic centers of innovation, including Boston, South San Francisco, and San Diego. In each locale, Lilly Gateway Labs serves as a catalyst for community-building across life science sectors, synergizing the efforts of biotechs, venture partners, and other ecosystem partners.

Lilly Gateway Labs is part of Lilly Catalyze360, alongside Lilly Ventures, Lilly ExploR&D, and Lilly TuneLab, which together support biotech innovation by providing access to strategic capital, lab space and technology, and research and development capabilities including advanced AI models. Since the first Gateway Labs site opened in 2019, resident companies have collectively raised more than $3 billion, fueling progress on over 50 therapeutic programs.
