We back legends in the making

We have two exciting announcements today as Cantos turns 10… First, we closed our new fund earlier this year. Canto IV is a $70M fund purpose-built to lead pre-seed and seed rounds. We oversubscribed, wanting to keep it right-sized for being a founder's most aligned first partner. Second, we launched our new look with help from our friends at @asimov_co! Cantos is so-named as an ode to epic poems, where grand stories are written in "cantos" rather than chapters. We view founders as the protagonists of today's epics and seek to back those whose deeds become the stuff of legend. Our new website is a testament to the scale of their ambitions, with visions from a future they will have shaped. Resonat in Æternum 🖋️

Replying to @IanRountree
@IanRountree is a truly generational investor and a close friend. Couldn’t be happier to have him joining our board
There's a subset of the @cantos portfolio we call "inconvenient truths". Rather than turn a blind eye we look to partner with founders running toward these problems. One of the most alarming is how unprepared we are for biothreats, evolved or engineered. Jake has shown incredible agency and a tireless urgency on this front. We led @pilgrimlabs' pre-seed and more than doubled down in this round alongside @joshbuckley and some superstar angel investors to help meet this critical need. I'm proud to be joining Jake's BoD as well.

You should absolutely press “stop pandemic”.
whatever you do, don’t press “stop pandemic” at the bottom of pilgrimlabs.com

Building a bio-shield for humanity by ~2030 is one of the great quests (to use @_sholtodouglas' term) of our time. It's one of the biggest, most exciting technological challenges ever This is why I'm excited about @pilgrimlabs
1/ Biological threats can bring a country to a halt without a single shot being fired. Yet much of our biodefense infrastructure has barely changed in decades, even as America’s institutions produce extraordinary scientific breakthroughs.

A country should control its own pipes. Astranis enables this.
How much control does a nation actually have over its network? Every nation relies on connectivity. But who truly controls it? A nation's hospitals, ports, government, and armed forces all depend on secure, reliable connectivity. Sovereignty can mean different things across the satellite industry. The difference comes down to how much control a nation actually has. With Astranis, nations control their networks through 5 dimensions: routing, priorities, coverage allocation, ground infrastructure, and encryption keys. To learn more, read our full white paper, The New Rules of Sovereign Connectivity.

Cantos founder and managing partner @IanRountree shares a major lesson from pre-seed investing. “I made a judgment: ‘I don’t think this technology is going to work, I don’t like this market, or this business model doesn’t make sense to me.’ I was pretending that I was underwriting a business that didn’t exist yet.”

The ADCU is a lot more than just defense, and the @Nominal_io team did a great job illustrating some of the ways @ShinkeiSystems touches so many different parts of our food chain Our best companies have endless stories about all the ways they work with their customers, suppliers, communities, and more This captures that magical feeling when you bring new technology to an industry that desperately wants it
Beautiful, precise engineering.

Apex is The Spacecraft Platform Company. For most of space history, progress was measured in firsts. First satellite. First human in space. First Moon landing. The next era will be measured in rate: how fast you can deploy, replenish, and refresh the infrastructure everything else depends on. That’s the New Space Race. Winning it takes constellations: many satellites working together as systems. And constellations require two industrial capabilities: launch and spacecraft platforms. Launch is ready enough. Platforms are not. Apex exists to remove that bottleneck.

Archer AI introduces useful autonomy to warfighters through features like Terminal Guidance and GPS-Denied Position Hold, both capabilities designed to improve mission success by reducing operator cognitive load and improving their strike accuracy. Like all Neros platforms, Archer AI is designed to extend warfighter lethality, and be mass-manufactured right here in America.

Radiant dares disturb the universe.
The @USArmy has awarded Radiant $750 million to deliver 15 Kaleidos microreactors through the Janus program, one of the largest contracts @DIU_x has issued to date. The Army launched the Janus Program to strengthen the energy resilience of military installations and mission-critical infrastructure. Radiant was chosen after extensive evaluation of reactor design, technical maturity, manufacturing readiness, deployment strategy, and commercial viability. Radiant’s 15 microreactors will enable the Army to deploy nuclear power across multiple locations. In tandem, the operational data acquired through the Program will accelerate commercial deployments across a global footprint of commercial customers. Learn more: radiantnuclear.com/

Earlier this year we became one of Asymm's first two investors with our friends at Interlagos. We swell with pride to support their mission and eagerly await a time when we can share more. Light of angels protect us.

There is no easy way to build what matters. Blackbeard is worth the work.
