Stoked to get to finally announce Wave Function Ventures $15M Fund 1! Wave Function was created to partner with deep tech founders building hardware solutions to the world’s most important problems. I'm 9 investments in, with 15-20 left to go.

We have shipped our 20kW satellite - Gravitas - to the launch site. Given the supply chain to operate at this power regime doesn’t exist, we had to build 85% of the satellite in-house. This includes building our own large solar arrays, high power propulsion system, large batteries, large reaction wheels and much more. This launch will represent the first time all of these systems are test on orbit together. Internally at @K2SpaceCo, we’ve thought about a few levels of success for this mission - we expect mission success to fall somewhere along this spectrum: - Tier 1 (Baseline mission success): Deploy solar arrays, establish comms, operate the satellite —> we’ve now got an operational 20kW satellite on orbit - Tier 2: Power on the payloads, activate the 20kW propulsion system —> we’re completing payload missions and have fired the highest power hall thruster ever flown on orbit - Tier 3: Orbit raise the satellite, test performance in high radiation environments (like 2,000km) —> we’ve collected massive amounts of data on the performance of the platform in very very difficult environments More than anything, Gravitas represents the start of an iterative journey, where we will take the data we receive from this first satellite and incorporate it into the next wave of satellites launching next year. We’re excited to start this journey, we’ll report back as we get more data. Thanks to Tim for covering our story on TechCrunch techcrunch.com/2026/03/19/k2-…

Private invitation release in three weeks, Tuesday 4/7.

Thank you Robert Goddard for enduring the naysayers and bringing us this wonderful technology that I have made a career out of. The Space age couldn't have happened without you.

@noah_schochet It’s embarrassing

Claiming the name “Stargate” for a data center is so lame. Nothing to do with stars or gates. That name should be reserved for a massive orbital space station. I think badass names for things should be protected. You gotta have a legitimate use for a cool name and use it or lose it.

@phil_hellmuth Great hanging out man. Sorry about your chips! But the future is looking good!

Solid-state batteries are changing naval warfare. And the threats they enable are far harder to detect. A post recently went viral claiming Iran's "Azhdar" UUV patrols at 18–25 knots with 4-day endurance and 600+ km range. This appears to be false, but the post went viral because the narrative is true. UUVs are a growing threat and maritime, as demonstrated by this crisis, is more important than ever. And the stakes are high. Iran has long held the Strait of Hormuz as a pressure point; roughly 20% of global oil supply flows through a 21-mile-wide chokepoint. UUVs capable of covertly laying mines in those waters would further threaten naval assets and escalate the conflict. UUVs are already being deployed by multiple nations. Today's lithium-powered vehicles cover hundreds of kilometers and patrol for days. Solid-state batteries at 400 Wh/kg, and climbing, mean that gets dramatically better, cheaper, and more scalable this decade. Sensing underwater is categorically harder than any other domain. cUAS has radars, cameras, RF, microwave. The electromagnetic spectrum works for you in air. Water kills RF. Acoustics are the primary detection modality, and littoral environments add clutter and complexity that open-ocean legacy systems were never built for. Those legacy systems were designed to find large submarines in deep water. Not swarms of small autonomous vehicles near ports, chokepoints, and critical infrastructure. As UUVs get cheaper, faster, and more autonomous - sensing is the defining gap. cUUV is going to be a massive market. Interdiction starts with detection. And detection underwater is still largely unsolved.

@AdamDraper Thread!

I'm turning 40 on Thursday. So naturally I'm celebrating all month. Something I realized is that 40 gives you the opportunity to reflect, while also giving you a reason to celebrate.

@jimbelosic Seriously @jimbelosic this is the best post I’ve seen on X in months.

Previous experience of my newest 12 manufacturing hires: - donut shop worker - accounting assistant - elderly caregiver - janitor - bartender - AI data analyst - call center rep - nurse at the VA - associate at Dollar Tree - hospitality associate (?) - school custodian - graphic designer I'm asked all the time about "how will manufacturers find skilled labor as we scale and reshore" and the answer is we have to create it ourselves. Relying on someone else (a school, the government) to create skilled labor for you means you're gonna be waiting a while. Just do it yourself. On-the-job training is the only way I've ever known how to hire. I think I was really lucky to come from a small town where OJT was common, and often the only way to learn how to do something. We have a 19 year old running a $1M Matsuura MAM, and a 70 year old running another machine next to him. Both produce great parts. The labor supply is endless if you are willing to put in the effort.

@jimbelosic Someone please scale @jimbelosic

Most anything past a basic spreadsheet for what you are referencing is productivity porn, not real work. Legibility and tweak ability will remain key benefits of spreadsheets and for anything more serious either AI or hardcoded code will be used. But def not the end of spreadsheets

prediction re the end of spreadsheets AI code gen means that anything that is currently modeled as a spreadsheet is better modeled in code. You get all the advantages of software - libraries, open source, AI, all the complexity and expressiveness. think about what spreadsheets actually are: they're business logic that's trapped in a grid. Pricing models, financial forecasts, inventory trackers, marketing attribution - these are all fundamentally *programs* that we've been writing in the worst possible IDE. No version control, no testing, no modularity. Just a fragile web of cell references that breaks when someone inserts a row. The only reason spreadsheets won is that the barrier to writing real software was too high. A finance analyst could learn =VLOOKUP in an afternoon but couldn't learn Python in a month. AI code gen flips that equation completely. Now the same analyst describes what they want in plain English, and gets a real application - with a database, a UI, error handling, the works. The marginal effort to go from "spreadsheet" to "software" just collapsed to near zero. this is a massive unlock. There are ~1 billion spreadsheet users worldwide. Most of them are building janky software without realizing it. When even 10% of those use cases migrate to actual code, you get an explosion of new micro-applications that look nothing like traditional software. Internal tools that used to live in a shared Google Sheet now become real products. The "shadow IT" spreadsheet that runs half the company's operations finally gets proper infrastructure. The interesting second-order effect: the spreadsheet was the great equalizer that let non-technical people build things. AI code gen is the *next* great equalizer, but the ceiling is 100x higher. We're about to see what happens when a billion knowledge workers can build real software.

@caitlinbolnick1 Accept the insight

Something has happened with my X algorithm and I only get sad stories or funny tweets about feral toddlers. It's like a mirror i don't want to look into 😂

@MattGialich 😂

Heading to Austin, the best city in the worst state in the Union.

My brother (literal brother) @daviddgull just dropped a dope first album. Worth a listen and follow! open.spotify.com/album/4ixA7DNI…

@Melt_Dem If it’s a process may just want to keep it as a trade secret. Info doesn’t get out there and it’s very hard to identify if someone is copying a process and then defend it.

request from portco making manufactured product with a ton of process IP: "got anyone who can help me file patents? two things needed - 1. figuring out what of what we’ve made can be patented 2. writing and filing the patent" i said use AI 😅 but better suggestions welcome

@rcanedesignwrks New diligence test. Suggest a caviar bump. If they don’t look confused, pass.

I would literally rather perform bowel surgery on myself with a rusty spoon. If I were a VC I'd be paying attention to who attends such things but probably not for the reasons you'd expect.

@MichelleVolz @ngmxyz Woot!

Excited to officially announce the launch of Pax Fund I, a $50M early stage vehicle dedicated to founders transforming the foundational categories of society. 🇺🇸🚀 Wrote a bit about my journey and the thinking behind Pax below:

@RRR0BYN 😂😢

Netanyahu is the worst president the United States has ever had.

@caitlinbolnick1 If the problems outweighed the benefits significantly the pop would dwindle and CA wouldn’t be #1 in…nearly every stat that matters.

Sure California has lots of problems, but this was one of those weekends that made me so damn grateful to live here. ☀️

@risknc Twinkies := our nuclear stockpile

Twinkies despite popular belief only are good for about a month and a half.
