We're honored to be selected for the Black Flag 100.2 list for 2026.

Thanks to the @BlackFlagVC crew for the nod, and to @MillenAnand and the rest of @teamairbase for the work behind it.

Building the future of RF spectrum is a team sport. More to come.

[Black Flag @BlackFlagVC]

500+ founders. 1,500+ nominations. 100 companies.

The Black Flag 100 is back 🏴‍☠️

No VC votes. No fund picks. Just pirates chasing storms over certainty.

The 2026 list 🧵🏴‍☠️

@FCC votes today to replace the 1990s EPFD framework for GSO/NGSO satellite spectrum sharing. $2B in projected economic value, sevenfold capacity gain. Big day today 🚀

[Ari Rosner @rosner_ari]

A small thing happened this past week that will have a big impact. OMB's new rule: for any contract over $10M, agencies have to defend in writing why they didn't buy commercial. Two-thirds of FY24 federal contract spend was non-commercial. This will be interesting to track. https://t.co/qN0ezFSXXk

@FCC @Starlink It'll be interesting to watch the reactions to the upcoming vote, there's a lot of people with strong opinions on both sides of the issue

[Ari Rosner @rosner_ari]

The @FCC is reviewing decades-old rules to improve spectrum sharing between LEO satellites (like @Starlink) and traditional GSO (geostationary) ones. The big focus? EPFD limits. What are they, where did they come from, and what happens if we update them? A quick 🧵

[Brendan Carr @BrendanCarrFCC]

The FCC will vote this month to supercharge your Internet.

Lifting outdated power limits on satellite Internet means faster speeds and more capacity.

🚀 🛰️ 🛜

[Ari Rosner @rosner_ari]

The FCC’s NPRM looks to modernize this. Updating EPFD limits could replace rigid power caps with smarter, performance-based rules (like degraded throughput metrics already used elsewhere).

The result? More efficient LEO + GSO sharing = higher speeds, more capacity, and better broadband for consumers, all while still protecting existing GSO networks.

@OmarJPimentel @mpatrickwalton Sounds like someone needs a TurboTax for Spectrum

Really appreciate the coverage from @AlleyWatch, this is definitely my favorite quote I've given this week

Big win for New York’s startup ecosystem

Preserving QSBS isn’t just a tax win, it’s a signal that New York still understands how startup success actually works. The real economic engine for the state isn’t just the exit itself; it’s the years of all-in risk that early employees and founders bet on. Taxing that upside retroactively would punish exactly the people who create the jobs and innovation the state wants.

Ecosystems thrive on aligned incentives, not short-term revenue grabs. This keeps NY competitive instead of handing the next unicorn to another state.

[Tech:NYC @TechNYC]

Big news for NY startups! QSBS is here to stay.

From @politico: the idea now “seems to be moot” following strong, coordinated engagement from across the tech community—including a @TechNYC letter with 1,600+ founders, early employees, and investors.

This is a clear example of what’s possible when the ecosystem shows up together. We’re grateful to everyone who spoke out and helped ensure policymakers understood what was at stake.

New York remains the best place to build. 🗽

[Ari Rosner @rosner_ari]

It has been a huge week for @teamairbase.

The broad support from both familiar and new faces is invigorating. Our mission remains focused on ensuring government, military, and commercial innovators maintain American leadership through rapid and resilient spectrum access.

As we continue to tell the story of America’s invisible national security crisis, we also want to tell the stories of the team behind Airbase. Learn more about our team at https://t.co/2RmiMQtRWf

We’re hiring across engineering, business development, and more to join our mission. If you’re a natural fixer, check out https://t.co/si55IT1uzj

[Ari Rosner @rosner_ari]

The @FCC is leading the way in modernizing space spectrum policy. This is how America stays ahead in the new space race.

@BrendanCarrFCC nailed it: “The American companies, even the weird ones and cool ones, need plentiful access to spectrum…With today's action, we continue our spectrum abundance agenda to support our builders in space."

And yeah, the @FCC is one of the coolest agencies in Washington by just calling it what it is. It’s “weird space stuff”. 🛰️

FCC March 2026 Open Commission Meeting https://t.co/dj5GJmjscA

[Ari Rosner @rosner_ari]

When @MillenAnand and I first started sketching out what would go on to become @teamairbase, I never dared to dream that the firm which literally wrote the book on how software eats the world would be in our corner as we strive to bring the world closer together. Spectrum is the very medium that makes global interconnection possible.

It’s a powerful reminder that the arc of innovation bends toward those who see something broken and act on it with rigor and audacity.

(And that Gov contract? That’s only the beginning)

[a16z @a16z]

We’re very excited to back Airbase.

@teamairbase is building the software platform for radio frequency spectrum — the unseen highway that carries the data on which our economy and national security depend.

The number of devices and systems that rely on spectrum is exploding. Airbase is bringing modern software to how airwaves are licensed, coordinated, and understood.

"We are at an inflection point. The commercial space economy is taking off. The nature of warfare is shifting to the RF domain. The devices in our pockets are becoming hungrier for data."

"The invisible infrastructure of our world is in crisis. And we exist to fix it.

Welcome to Airbase."
