Introducing Ground, the Money Infrastructure Company, supercharging banking and finance.

We have been quiet, building with design partners. Today, we launched out of stealth, alongside a $3.6 million pre-seed funding round, to embed onchain finance everywhere, starting with yield.

Ground turns any stablecoin or cash balance into a yield-bearing balance through one API. One integration provisions wallets, deploys into configurable on-chain yield sources, and emits ledger-ready accounting your end-user UI and internal systems can use on day one.

The bar is fintech UX, not blockchain UX. Yield should feel like a native balance feature, not a gas-and-retries engineering project. You pick allocations, set policies, and stay in control of funds. Ground hides blockchains and complex onchain mechanics.

Built for any financial platform or asset manager like neobanks, fintechs, corporate treasuries, and wealth managers. Founded by fintech and digital asset veterans from @stripe, @SuperstateInc, @hifibridge, and @compoundfinance. Backed by @BainCapCrypto, @paraficapital, @nascent , @robotventures, @chapterone, and Consonant Ventures.

- @rmcuming, CEO and @realsamyoon, CTO

🚨WE NEED TO HIRE MORE BANKERS!!! 🚨 @tryoffdeal is scaling fast and we need more firepower to keep up with the demand. We want to hear from you if you:

- Have 5-8 years of deal experience
- Love dealmaking - both execution and origination
- Want to own your own P&L
- Ready to build out sector coverage
- View AI as a force multiplier, not a threat
- Want to be in NYC in person

2025 was our first year and we're off to an incredible start, and this year is looking even crazier. AI capabilities are going vertical, buyer demand for lower middle market deals is at an all-time high, and 2026 is shaping out to be a record year for M&A.

If you're interested in learning more, we'd love to hear from you. And if you know someone that might be a good fit, give us a tip and we'll pay a $25K cash referral bonus if they get hired!

BACK-TO-BACK!

[ben guo 🏇 @0thernet]

today we're announcing @zocomputer.

when we came up with the idea – giving everyone a personal server, powered by AI – it sounded crazy.
but now, even my mom has a server of her own.

and it's making her life better.

she thinks of Zo as her personal assistant. she texts it to manage her busy schedule, using all the context from her notes and files. she no longer needs me for tech support.

she also uses Zo as her intelligent workspace – she asks it to organize her files, edit documents, and do deep research.

with Zo's help, she can run code from her graduate students and explore the data herself. (my mom's a biologist and runs a research lab. hi mom)

Zo has given my mom a real feeling of agency – she can do so much more with her computer.

we want everyone to have that same feeling. we want people to fall in love with making stuff for themselves.

in the future we're building, we'll own our data, craft our own tools, and create personal APIs. owning an intelligent cloud computer will be just like owning a smartphone. and the internet will feel much more alive.

THIS ONE'S FOR YOU MOM ❤️

special thank you to @modal, @pydantic AI, and @steeldotdev for being great partners leading up to this launch. and thank you @cursor_ai for being my sword 🗡️

@jaredhecht great read

@SubstrateLabs is the first API of its kind, optimized for running multi-step AI workloads fast.

I was lucky to meet @vprtwn @perceptnet within my first couple of weeks in VC (ty @jasonkimvc !), and was super impressed with their vision, speed of execution, and most importantly, with them as people.

They are bringing a much needed product to the AI ecosystem, and I can't wait for AI builders to get their hands on it.

[ben guo 🏇 @0thernet]

Last September, I left @stripe after 8+ years to build something new with my friend Rob Cheung.

Today, we're launching @SubstrateLabs , the first inference API optimized for multi-step AI workloads.
