.@DoxxnetHQ founder Barrett Lyon on data center myths versus reality: jobs, talent, and faster internet.
"That's the other thing that's driving me crazy, is people don't understand data centers at all... Data centers have been around for a very, very long time."
"People are being manipulated with this data center thing... It's very interesting to be in the know and then watch this and go, oh my goodness, these people are missing the mark."
"The big data center park in Virginia, you just see bunny rabbits in the field. There's nothing. It's just a big building and a bunch of parking lot and then nothing."
"It brings jobs. The people that work in them aren't getting paid pennies. And it also brings high tech talent. And then also infrastructure, and infrastructure powers everything you do. So if you have a data center nearby, your internet's faster. Things like that work better."
@BarrettLyon @YODELAGARZA
.@BarrettLyon built the first cloud DDoS-protection service, mapped the entire internet (now on display in New York's Museum of Modern Art), and got chased out of Moscow hunting Russian extortionists.
His new company is doxx.net, a parallel internet designed to keep advertisers, trackers, and creepy VPNs out of your life.
Barrett joins a16z's Joel de la Garza to explain what it is and how it works: a private network where messages, calls, and files travel directly between people instead of through someone else's server, and where nobody needs your name, number, or email to reach you.
They also get into why most VPNs are "just entry and exit points," why you can't set policy on equipment you don't own, the day Barrett's plane lost power over Oakland on the way home from a16z, and the data center myths that drive him crazy.

Replying to @BarrettLyon @a16z
Excited for the rest of the world to get to use @DoxxnetHQ too @BarrettLyon
I'm pretty sure it's been on 24/7 since I first started using it and I (+ my agents) won't use the internet without it on anymore!

This is a global overlay network that runs its own internal BGP, and DNS. Supports ipv6. Is distributed with no centralized log retention. Fully U.S based. And has great method for connecting agents without pair the device bullshit. Private and secure, from the đ, Barrett.
Today weâre launching doxx.net, enabling Agentic Defined Networking for everyone. We raised $38M from @a16z, @AnimoVentures and Focal.vc.
Create private networks for you and your AI agents, without a server in the middle. 38M+ threats blocked since December.
Our first private-network call was a freedom call. Now itâs your turn.

Still buzzing from yesterdayâs Miami Founder Summit đ„đ„đ„
Huge thanks to @ClementDelangue, @nejatian & @BarrettLyon for amazing sessions , @focal_vc for our incredible partnership and Miamiâs best founders for showing up, sharing, and building together.
We are so back đ
Big launch from Coworker: OM2, 9x cheaper enterprise AI. Congrats Alex and team!
Congrats to @coworkerapp and team on OM2, proof that memory beats bigger models.

Token costs are exploding
Companies have to choose: cut AI spend or cut people?
Coworker is the 3rd option
> Same frontier AI
> Chat, Cowork, Code
> 5X more tokens per dollar

Fifi is one of the most impressive founders we're fortunate to have backed - even though she's barely 18!
She's now hiring a founding engineer for Maxed. The most important thing when joining a company as a founding engineer is the founder.
Fifi's track record speaks for herself: Self-taught coder since 7, three companies before 18, speaks five languages, played competitive chess, and SO MUCH more.
Now, at 18, she's rebuilding accounting from the ground up as an AI-native operating system at Maxed, with backing from angels including the founders of Notion, DigitalOcean, and SecurityScorecard.
If you want to build with a founder who'll definitely raise your bar and intensity, take a look: maxed.life/hiring
I'm hiring our first, full-time founding engineer at Maxed đ
Accounting is one of the largest professional services markets on Earth and it's about to be rebuilt from the ground up.
Maxed is an open-source, AI-native operating system for CPA firms.
Design partners are live. The architecture underneath has never been built before and as a result, most of what we're doing has no playbook - you have to be the kind of person who finds that energising.
I'm technical, obsessed and this is my whole life. I need someone wired the same way.
Help rebuild a trillion-dollar industry from the inside out - apply here: maxed.life/hiring
Big news today. @coworkerapp just dropped Opus-quality enterprise AI for one-fifth the price. Same frontier models, 82% less cost.
Privileged to be joining Woods Hole Oceanographic Institution as a Corporate Board Member.
I feel most at home in the water. From marine research diving in Africa to ocean swims along the Australian coastline, the ocean has shaped some of the most meaningful parts of my life. Joining WHOI feels like an opportunity to channel that lifelong connection into something with real purpose.
I see us entering a remarkable era for ocean science. Despite covering most of our planet and being integral to life, the ocean remains one of the least understood frontiers on Earth. Over the next decade, breakthroughs beneath the surface could reshape how we think about medicine, food systems, climate, materials, energy, and biodiversity itself.
We have so much to learn, I can't wait.
A few things that make WHOI such an extraordinary institution:
- The worldâs largest non-profit dedicated to ocean research and engineering
- $500M endowment supporting long-term scientific discovery
- 1,000 employees, including ~500 scientists and engineers
- Joint program with Massachusetts Institute of Technology training the next generation of ocean scientists
- A fleet of world-class research vessels and deep-sea submersibles
- Nearly a century of advancing humanityâs understanding of the ocean
For 90 years, WHOI has been behind some of the most important discoveries in ocean science. Itâs a privilege to now contribute, in some small way, to what comes next.
Special thanks to David Scully and Paul Salem for the introduction, encouragement, and leadership.
If you care deeply about the future of our oceans Iâd love to connect.
Letâs get to work.
Congratulations to Nima Aghaeepour & Joe Phongpreecha for bringing Takeoff41, Inc. out of stealth today.
A Stanford-incubated startup modernizing care for pre-term babies in the NICU. Science published in Nature, first hospital live, grant funding secured and a big year ahead.
Iâve written recently about two ideas:
(1) category-defining missions, and
(2) AI as the wedge for offline monetization.
Takeoff embodies both.
Their AI software guides nutritional recommendations for TPN drip bags, often a premature babyâs only source of intake. Yet what I admire most is their ambition from day one to build a full-stack neonatal care platform focused on outcomes, not just tools.
Manufacturing and delivering next-generation TPN bags guided by their AI software â greater value to the customer, and greater value capture for Takeoff.
Deliver the outcome, not the software.
Proud for focal to lead their pre-seed alongside our friends at @BasisSet
Thesis-driven founders are winning.
Theyâre trading at a premium, attracting more VC capital far earlier. These are the Seed rounds making headlines.
Thesis-driven founders arenât selling products. Theyâre not leading with metrics. Theyâre articulating a point of view about how a market will develop, and inviting investors to underwrite that future.
And when the future is this in flux, that clarity feels like the calm in the eye of the storm. Everyone else is circling the outside, starting to look like versions of the same startup, competing and blurring into one mass.
You can usually tell which side youâre on from the diligence questions youâre fielding: what about X competitor, how do margins scale, whereâs the defensibility?
When a company is truly thesis-driven, the conversation shifts. It compresses down to something much simpler:
Do you believe?
Because if the thesis is right, multi-stage funds believe they can mobilize the capital and ecosystem around it to make it real. After all, VCs are in the belief business.
What really works for thesis-driven founders, especially those whose thesis comes from lived experience or deep technical insight, is that they create narrative momentum.
In a world changing this quickly, narrative momentum becomes a magnet. It pulls in capital before itâs obvious, attracts talent who want to be part of something meaningful, and signals to customers that this company might define the space rather than follow it. Over time, that belief compounds.
Iterative product building, on its own, can trap you in the present.
This isnât fake it till you make it. Itâs hard. Itâs building real conviction to call the future early, and then building toward it before the rest of the market catches up.
At Focal, these are the founders weâre drawn to.
Dream far out. Dream deeply. Create your narrative momentum.
Better AI products are not winning by default right now.
Iâm seeing weaker solutions raise at 5â10x the valuation of stronger ones at the same stage â $6M seed vs $50M for companies that shouldnât be in the same conversation. Customers arenât seeing the value yet, revenue isnât there, and the tech is often underbaked. Founders feel it when those funding headlines hit.
At the core, this is a market rewarding sizzle over steak.
During seismic platform shifts, multi-stage funds become power-law maximalists. Theyâre not trying to be right often â theyâre trying to be massively right once, and put as much capital behind that outcome as possible. So they back what could dominate â the big story, the founders who can sell the winner early â not the product thatâs already better.
And once that capital lands, it compounds. Customers behave the same way. They want to buy the winner â the product with momentum, that feels inevitable, that will still be around in 5 years. Startup IBM.
So capital becomes momentum. Momentum becomes belief. Belief becomes reality.
The uncomfortable implication is that having the better product isnât always enough. You have to win on multiple fronts: persona, narrative, speed, distribution, hiring, capital.
The best founders donât just build. They outmanoeuvre.
Counterintuitive feeling right now as a pre-seed investor: the fast, iterative startup is the riskier bet.
Shipping fast isnât optional, itâs expected. AI founders are told winning means launching on day one, hitting $5M in 12 months, and marking your arrival with an iconic round⊠then sprinting uphill again.
The problem is everyone is running that same race, and fast products donât stay differentiated for long â they get absorbed, copied, and iterated to the norm quickly.
The companies that matter most often take longer to emerge. They start from the end state, build what isnât yet visible, and are willing to look foolishly early.
Founders willing to boil the ocean have suddenly become the safer bet.
As five-year moonshots collapse into months, those are the companies we want to build our portfolio around. The patient capital that has since become scarce in today's market.
Itâs uncomfortable for founders and VCs. But thatâs kind of the point.
As Anthropic melts away entire categories, the bar for what makes an interesting pre-seed investment has shifted.
I increasingly find myself backing three types of companies:
1. Mission impossible
Technical or scientific founders going after problems long deemed out of reach â now within striking distance because of AI.
AI isnât the product, itâs the unlock.
2. Trojan horse
Agentic workflows used as a free or low-cost wedge â with real value accruing at the transaction or financial layer beneath.
3. Data treasure hunters
Businesses that unlock novel, hard-to-access data â then build the model and feedback loop around it.
Own the data, own the outcome.
Weâve invested across all three recently.
In fact, we hit a Focal record : deploying $10M over the last quarter.
2026 energy is on đ„
Fascinating to see AI business models morph. Seems the way AI is monetized may be more disruptive (and defensible) than the tech itself?
Most discussions are SaaS to usage or Per seat to outcome. I'm seeing more novel models that are 10-100X the value of a seat.
Startups where AI isnât the product being charged for, but rather a foothold into much larger pools of value.
A few recent examples:
1. AI monetized by physical goods
Biotech offering AI diagnostics at cost, then capturing value selling the drug compounds their models identify.
2. AI monetized offline
Free AI predictive maintenance on industrial equipment used as the wedge to sell long-term servicing agreements and maintenance contracts.
3. AI unlocking financial assets
Insurance workflows where AI structures claims for easy remediation, which then become securitized financial assets for trading and lending.
I love seeing this kind of thinking. If youâve seen other interesting models - or are building one - please let me know!
