Fifty Years is a San Francisco-based venture capital firm specializing in pre-seed and seed investments in deep tech startups addressing humanity's biggest challenges, such as climate crisis, disease, connectivity, and malnutrition.[3][2] Its mission centers on backing scientist-founders and engineers to build massive businesses using technology for good, while also actively helping start companies through initiatives like cohorts for deep tech startups.[3] The investment philosophy emphasizes "founders all the way down"—founded by successful entrepreneurs, backed by 46 founders of $1B+ companies, and supporting PhD-heavy teams with over 4,104 papers and 355,320 citations among its founders.[3] Key sectors include technology, life sciences, healthcare, climate, energy, cyber, and related deep tech areas, with a strong impact on the startup ecosystem by providing a "cheat code" for scientists becoming entrepreneurs and fostering world-class networks.[2][3]
Fifty Years was founded by partners including Seth Bannon and Ela Madej as founding partners, alongside Dr. Alex Teng and D. Scott Phoenix, evolving from a focus on pre-seed/seed tech and life sciences to actively incubating deep tech companies.[2][3] The firm emerged to bridge the gap for world-class scientists and engineers—many with PhD backgrounds—lacking entrepreneurial resources, backed by giants like founders of unicorn companies to leverage their experience.[3] Early traction includes closing four funds by 2023, backing 72 PhD founders and 33 PhD CEOs, and launching initiatives like the 5050 program and upcoming cohorts (next in March 2026), positioning it as a founder-centric force in deep tech.[2][3]
(Note: Fifty Investments Limited, a separate UK entity incorporated in 2016 focused on management consultancy, does not align with "Fifty - Fifty" in the VC context.[1])
Fifty Years rides the deep tech wave, capitalizing on AI, biotech, climate tech, and energy transitions where scientific breakthroughs demand specialized early-stage funding.[3][2] Timing is ideal amid surging demand for PhD-led innovation to tackle global crises—climate, disease, malnutrition—fueled by market forces like government incentives, corporate R&D shifts, and VC appetite for high-impact, scalable tech.[3] It influences the ecosystem by democratizing entrepreneurship for non-traditional founders (scientists, hackers), amplifying "capitalism as a force for good" through backed unicorns' shoulders and incubation, thus accelerating solutions in underserved sectors like cyber and connectivity.[3][2]
Fifty Years is poised to scale its incubation model, with the March 2026 cohort signaling aggressive expansion into more deep tech unicorns amid rising AI-biotech convergence and climate urgency.[3] Trends like sovereign AI funds, synthetic biology, and net-zero mandates will propel its portfolio, potentially evolving its influence from niche pre-seed player to deep tech ecosystem architect. As founder-backed networks compound, expect Fifty Years to redefine how science fuels trillion-dollar markets—turning "fifty years" of progress into decades.
