Life expectancy surged by more than 30 years across the 20th century — driven by antibiotics, vaccines, insulin, statins, and more recently GLP-1 receptor agonists now demonstrating reductions in all-cause mortality. These advances converted once-fatal conditions into manageable ones. Yet the gain in lifespan has not been matched by a commensurate gain in healthspan. Worldwide, the gap between how long we live and how well we live has widened over the past two decades.

Of adult life now lived with morbidity
Neurological and neurodegenerative disorders affect 55 million people globally (projected to 139 million by 2050); cardiovascular disease claims ~19 million lives annually; metabolic conditions affect over 500 million. Current medical interventions are optimized for extending lifespan and treating individual diseases, not for targeting the biology of aging itself. The evidence suggests this is modifiable: geroscience interventions have the potential to reduce the healthspan-lifespan gap by 40–50%, and delaying aging onset by just 2–3 years is estimated to generate tens of trillions of dollars in global economic value over the next half-century.
What the Field Still Lacks
Interventions that target the underlying biology of aging rather than its downstream manifestations
Validated therapeutic avenues capable of compressing morbidity into the final months of life
Robust translational pathways from geroscience discovery to clinical application
Entrepreneurial scientists equipped to bridge the academia-industry divide in healthspan research
The Translation Imperative
An Evolving Scientific Landscape
The postdoctoral training system has historically focused on preparing scientists for academic research careers. However, an important opportunity remains underexplored for many young and brilliant minds in academic science: cultivating an entrepreneurial mindset and a translational focus that enables their efforts to reach their full impact for the betterment of human life. This vision requires rewarding entrepreneurial thinking that enables exceptional researchers to see the broader impact of their efforts, beyond the laboratory bench. For example, a postdoctoral fellow who understands the broad frameworks of intellectual property strategy, sources of capital, and how to assess a given druggable target, can make fundamentally different research decisions by asking not only "Is this scientifically interesting?" but also "Could this solve a real problem, and how would we get it there?"
Empowering Postdoctoral Fellows
Some institutions are beginning to address this gap through programs that incorporate entrepreneurship training, translational medicine exposure, and exposure to commercialization strategies into traditional postdoctoral experiences. These initiatives recognize that the founder mindset — the ability to identify unmet needs, assess feasibility, build teams, and navigate the complex journey from discovery to application — is not antithetical to rigorous academic science but rather a natural extension of it.
The challenge facing the global research community is to systematically equip our most talented postdoctoral researchers with the translational literacy and entrepreneurial confidence to transform their academic insights into rigorous solutions that reach the people who need them most. The goal of this Request for Applications from Critical Mass Ventures is to meet this important need by providing the first-in-kind bridging support for the most innovative scientific solutions from visionary postdoctoral fellows.
The Healthspan Imperative fellowship supports the postdoctoral scientists who are best positioned to change this. We fund researchers who have already made significant contributions and are seeking structured support to translate their findings into real-world applications. This is not a career pivot away from science — it is an expansion of it.

The complete Request for Applications document includes all program details, eligibility requirements, application guidelines, and review criteria in a single PDF suitable for sharing with colleagues and mentors.
Yes — we strongly encourage entrepreneurial applicants. Your career development plan should outline your company formation thinking, including the problem you're solving, your current stage, and concrete next steps.
What if I haven't identified a specific industry position yet?
That's expected. Focus on career direction, the therapeutic area you're most interested in, and concrete steps you plan to take to explore opportunities. Clarity of intent matters more than a locked-in plan.
I'm in my 6th year of postdoc. Am I eligible?
Possibly. Contact us before applying to discuss your situation. Extensions to the postdoctoral period for parental leave, medical leave, or visa delays are considered on a case-by-case basis.
Can international postdocs apply?
Yes. There is no citizenship or nationality requirement. You must be employed by an eligible institution in California and hold appropriate work authorization for the duration of the fellowship. Visa delays that extended your postdoctoral period may be considered for eligibility extensions.
Do I need to transition to a position in California or the United States?
No. You may transition to industry or entrepreneurship anywhere in the world. Your application should articulate how your target region's ecosystem supports your translational goals.
Will my application be disadvantaged if English is not my first language?
No. Applications must be submitted in English, and we welcome applicants from all linguistic and cultural backgrounds. Clear communication of your science and vision is what matters.
My research is early stage but has strong translational potential. Should I apply?
Preliminary data is essential to a competitive application. If you are still generating foundational proof-of-concept results, we encourage you to apply in a future cycle once you have data that supports the translational pathway you envision.
Do I need an industry mentor to apply?
An industry mentor is not required at the time of application. However, we encourage you to describe any steps you plan to take to develop relationships with appropriate industry mentors during the fellowship period.
Can I hold this fellowship alongside an NIH F32, EMBO, HFSP, or similar award?
No. Concurrent salary support from multiple individual postdoctoral fellowships is not permitted. If you hold a non-salary award (e.g., a travel grant or training grant), that is generally permissible. Contact us to discuss your specific situation before applying.
What if my career transition takes longer than the fellowship period?
We understand that transitions take time. The fellowship is designed to catalyze and accelerate your path, not to complete it. Should you remain in an academic position following the fellowship, we expect you to have made documented progress — and ideally to articulate how your academic role can accommodate entrepreneurial activity (consulting, start-up involvement, etc.).
