This information reflects the track record of Anna Brady-Estevez across prior institutions, including the National Science Foundation. The $10B+ in follow-on financing represents capital invested by subsequent investors into companies from her early-stage portfolio. Companies initially supported at the early stage with approximately $250M in funding have gone on to achieve more than $21B+ in total company valuation.

Prior early-stage portfolio funding amounts refer to awards and grants and are publicly available through the NSF Award Search under “Anna Brady,” reflecting activity during her tenure as Program Director (2017–2024). Company valuation data is derived from public records and Pitchbook for private companies that received grants, as of April 23 2026. No representation is made that these figures will be updated beyond that date.

For the NSF portfolio, illustrative equity cash-on-cash returns may be modeled by using company valuations at the time grants were awarded (or reasonable market assumptions where data is unavailable) and applying dilution assumptions consistent with subsequent funding rounds. Past performance is not indicative of future results. There can be no assurance that future performance will exhibit similar characteristics or returns. Gross TVPI estimates are modeled for the years 2017–2021 and do not account for management fees, performance-based fees, or other expenses that may materially reduce returns. Companies from later years (2022–2025) are earlier in their development cycle, though similar modeling methodologies may be applied.

The total valuation of $21B+ reflects the aggregate market capitalization of companies within Anna Brady-Estevez’ deep technology portfolio, including Fluence, which originated from her corporate work at AES. All other referenced figures relate to the NSF portfolio, where investments were structured as grants.

Building the Frontier of Abundance Together

American innovators and scientists have historically defined the possible, delivering solutions that generate global abundance. Yet, for too long, the “physical” sciences and deep technology have faced a critical capital gap—slowing the progress the world urgently requires. At American DeepTech, we are investing in the future and closing that gap.

We believe the next era of value creation lies at the intersection of AI Genesis—the application of artificial intelligence to R&D, fundamental science, and physical infrastructure. From autonomous space exploration and oncology breakthroughs to energy resilience and quantum overmatch, we invest in the technologies that secure our future.

Team Prior Leadership and Scale

We are more than investors; we are inventors and builders who have built companies from the earliest stages to unicorn levels and operated at the highest levels of global infrastructure and national security.

Founder Track Record

Unicorns: Funding and investing from the early stages into numerous unicorns.

$20B+ in Value: Early funding and investment to companies achieving ~$20B+ in total company valuation.

$T+ Scale: transformation work leading to trillion-dollar+ IPO.

The Operational Edge

$150B Asset for R&D: Leadership at the International Space Station (ISS), focus on commercial R&D.

$35B+ Industrial Base: work to build the US Space Force and Air Force industrial base

National Leadership: Former leaders within the NSF, NASA, Co-chair alongside White House OSTP in US Digital Assets R&D agenda; worked to establish the National AI Research Institutes.

Ongoing Partnerships and Collaboration: NASA, ISS, and work with US Congress

Join us at American DeepTech as we build the future today!
