Fellow SignalPoint of View →

Fellow Signal is an intelligence layer on Activate's fellowship, 224 hard-tech ventures and 292 scientist-fellows (2015–2025), built entirely from public data. Four things the data says:

01

The picks win, independently. $227.2M in federal non-dilutive funding across 46% of ventures, DOE-led, before any equity round.

02

The frontier is moving. the 2025 cohort pivoted into Climate (2%32% of the cohort), discovery should track the acceleration.

03

Discovery isn't selection. a founder's research footprint finds scientists years early, but doesn't predict outcomes, use it to find, not to rank.

04

The whitespace is visible. emerging science with fresh federal money and no Activate fellow yet (Concrete and Cement Materials), the earliest sourcing leads.

Whitespace (bottom-right) = fields whose research is accelerating but where Activate has few ventures yet, an opportunity gap worth investigating.
Real data: research momentum from OpenAlex (an open index of ~250M scholarly works), as each field's growing share of publications; bubble size is federal funding momentum from USAspending.gov; presence is Activate's portfolio. Fields are keyword-defined and point-in-time, so trust the ranking over exact magnitudes.

Insightswhat the data says, and the so-what
Frontier shift
The 2025 cohort pivoted hard
Climate 2%32% of the cohortElectronics & Connectivity 8%24% of the cohortcohorts of 50 and 38, so directional
So what: Where Activate sources is moving year to year, discovery should track these accelerations, not last cohort's mix.
Whitespace
Hot science, hot money, Activate light
Transportation & Mobility: research ×5.2, federal $ ×99+, presence 7%Energy Storage & Batteries: research ×4.5, federal $ ×15, presence 11%
So what: The clearest sourcing-opportunity gaps: fields the science and the funders are racing into, where Activate is under-represented.
Hub thesis
New York is a climate & carbon cluster
Carbon Management +33pp vs the portfolioClimate +24pp vs the portfolio
So what: Hubs aren't interchangeable, each is a distinct bet, so sourcing and partner cultivation should be hub-specific.
Outcomes
The selections win money on their own
$227.2M in federal non-dilutive funding across 46% of ventures
So what: An independent, public validation that pick-quality converts to real traction, before any equity round.
Model
An equity-free model that 7.2×'d its budget
Revenue $3.7M$26.7M (20192023), funded by philanthropy + government, not VC
So what: A scalable, founder-first alternative to the accelerator model, and the growth shows it's resonating with funders.
Discovery signal
The science predicts the venture, years early
Founders' pre-founding publications map onto their companies, e.g. Ryan DuChanois's membrane / ion-separation research → Solidec's electrochemical reactors.
So what: Research footprints are a leading indicator for founder discovery, surfacing scientists before they've incorporated.

Training88% of fellows hold a PhD, a baseline, not a gate

A starting screen, not a scorecard to optimize: it points sourcing at the right space and the scientist profile that has worked there.

Does the signal track outcomes? (honest answer: not yet)
Closing the loop: 89 companies with a founder research profile, split at the median citation count, on the rate of winning federal non-dilutive funding.
38%
won federal funding
Above-median research depth
36%

Below-median

At this sample, founder research depth does not predict federal funding, the funded rates are within a couple of points. The average dollars differ ($300K vs $220K), but that gap is driven by a few outsized DOE awards, not a broad effect. The honest read: the loop is the right instrument, the predictive signal isn't there yet at this N, and that is worth knowing rather than dressing up.

Candidate surface for curation, not a ranking to act on blindly. Research is share-normalized (growth above ~8× filtered as a coverage artifact); federal momentum uses curated keywords against USAspending and only counts when current funding is material (≥$20M), so tiny-base ratios can't dominate. 18 of 28 topics are open.

Where The Engine (MIT's deep-tech VC) concentrates vs Activate · click a space to filter
Activate (224 ventures)The Engine (57 companies)share of each portfolio by space
The Engineis MIT's "Tough Tech" venture firm (founded 2016) and invests for equity; Activate is an equity-free nonprofit fellowship. So this compares where two different models concentrate, not their stage or structure. 57 portfolio companies from their public listing.

The Engine's taxonomy is coarser than Activate's (its catch-all "advanced engineering" tag inflates Manufacturing & Robotics), so read this as directional positioning, not a precise overlap. Source: The Engine's public portfolio page, mapped onto Activate's 16 verticals.

A different model: an equity-free nonprofit, scaled by philanthropy and government rather than venture capital. That $26.7M of annual money-in backs the fellows whose ventures have, in turn, pulled in $227.2M+ of federal non-dilutive funding, before private capital.
