Happy Wednesday! If you’re new here, welcome to Necessary Nuggets, your one-stop pre-seed shop. We deliver updates from Necessary Ventures and helpful tidbits on our little corner of the world. Every edition is also on our blog.
What's happening at Necessary Ventures:
Arc raised $50 million in a Series C round from Eclipse, a16z, Menlo Ventures, Lowercarbon Capital, Offline Ventures, and your very own Necessary Ventures. With this funding, Arc is expanding into defense tech, planning to sell electric propulsion systems to defense contractors. More from Bloomberg.

Data migration
The AI talent pool is graduating straight from universities to corporate labs. An interesting new paper published by the National Bureau of Economic Research documents how AI research has dramatically shifted from academia to industry over the past two decades. Using a dataset linking publication records to U.S. Census employment data, the authors track 42,000 AI researchers and show that top industry salaries have quintupled since 2001. The shift inevitably drives early-career talent toward compute-rich incumbents like Google, Meta, and Microsoft. Meanwhile, university salaries stagnated or declined. As researchers move into industry, their output shifts sharply: academic publishing dropped by roughly 63% while patents increased sixfold, signaling a move from open science toward proprietary, commercially focused innovation. Additionally, female representation has grown more in academia than in industry, and pay gaps remain substantial. The study paints a picture of a frontier innovation ecosystem increasingly shaped by corporate resources and commercial incentives. Classrooms are out; the cloud is in.

Check, please
It's SPAC to the future for startups. SPACs are making a strong comeback, now targeting deep-tech companies with a focus on quantum computing. After their rise and collapse in 2021, SPACs are returning as a faster, more capital-certain path to public markets, allowing startups like IQM, Pasqal, Infleqtion, and Xanadu to raise hundreds of millions of dollars quickly without traditional IPO requirements. The surge in SPAC activity is fueled by high public-market appetite, partly driven by AI-related compute bottlenecks and recent advances moving quantum machines from the lab toward practical applications. Venture capital funding for quantum has more than tripled recently, but private money alone isn’t sufficient to commercialize the hardware. SPACs are also drawing attention in other deep-tech areas, like nuclear fusion and space ventures. Startups are jumping into public markets faster than you can say “double-slit dilemma.”

Hot stuff
Here’s your cue to stay in touch with current events. A new wave of fusion startups is racing to develop commercially viable reactors, with a collective $10 billion raised. Most people couldn’t tell you what fusion actually is. At its core, fusion generates electricity by fusing atoms, and startups are experimenting with two main approaches: magnetic confinement and inertial confinement. Magnetic confinement uses powerful superconducting magnets to contain superheated plasma in tokamaks or stellarators, and inertial confinement compresses fuel pellets using lasers, pistons, or electromagnetic pulses. Notable players include Commonwealth Fusion Systems, Tokamak Energy, and several European stellarator-focused startups. Laser-driven inertial confinement has already reached scientific breakeven in lab settings. With demonstration devices like CFS’s Sparc expected to turn on in 2026 and commercial-scale plants planned soon after, the industry is moving rapidly. There’s no doubt fusion startups are headed for a bright future.

Here's what the week looked like in pre-seed:

Data aggregated from proprietary research and Crunchbase; valuation estimate based on 10-20% ownership stake.

SEED IT TO BELIEVE IT
Founding team ownership is split: early-stage founders are facing an equity squeeze while late-stage founders see gains compared to 2018. Seed and Series A ownership hit a low in 2024, down as much as 3.5%. Last year, Series D ownership increased to 2.3% compared to 2018, perhaps pointing to a survivor's premium.
