The best way to predict the future of global banking is to build it. I’m thrilled to share that I’m joining @KASTxyz as General Manager, US.

Excited to connect at @thestablecon back home in DC with the @KASTxyz team. Some thoughts -- 1/ More providers launching niche angles for net new use cases 2/OCC charters are the new badge of honor 3/Coverage + consumer experience still matter more than rail commoditization 4/Seeing even more folks from my web2 days means the lines between the two are more blurred than ever 5/Everyone asking what @stripe and @Stablecoin are up to.. nice try. Good to be home.

flew on the inaugural @united A321XLR flight this morning. people flew in from around the country to be on it. someone offered me $2,000 for my seat. incredible plane. incredible experience. only question: who decided the first flight should be on 9/11 🫪

Anyone in DC for @thestablecon this week? Let’s jam about how cool this industry is now. Come say hi. @KASTxyz @raagulanpathy @KamalBeiruti

the amount of times @HelloFresh has sent direct mail larping as a financial summons or debt collector needs to be studied. five plus years running the same campaign, ten years since I ordered..

Kast for Business open for biz 🙏 Couldn't be more excited for this launch

A bit on what we’ve been cooking up @KASTxyz Much much more to come. Learn more below

stablecoin supply went from $3B to over $300B in under a decade. adjusted volume hit $10.8T last year. february was the month onchain settlement passed ACH, $7.2T against $6.8T. real payments are still a sliver of the total. roughly $390B in 2025, thirty times the level two years earlier. the curve is the point. the TAM is everyone with a phone -- the freelancer in manila with no path to a US bank account. the SMB in nigeria settling a supplier invoice in seconds. the consumer in argentina holding dollars without a dollar account. banking is regional because rails are regional. stablecoins reach all three on day one. artemis published the thesis today on @KASTxyz . We're only scratching the surface for consumers and businesses..

Why did we build “Reserve”… plus, how do we fund it, and what comes next? Let me lay it out…. 1/ The 6-9-12% for standard-premium-private is introductory, and will drop to 4-6-8% in 2027 (or maybe I’m nice and I extend it!) 2/ We only hold funds in treasury backed stablecoins or similar. No vaults or funky rates. The gap between those 3.5-4% rates and what the user gets is for three reasons… a) It’s a membership benefit. They pay a subscription, and we offset the cost partially via the subscription. b) We use it for Customer Acquisition, it literally sits on our P&L on this line c) It’s a the setup for Credit… let me explain more. 3/ The next step for Reserve, is our Charge Card style product… then credit. a) You will get a monthly balance, which you can spend from Reserve and keep earning rewards still. At the end of the month you get a statement, and 10 days to pay. Pay it via an external top up, and your spend of the previous month was a 0% loan and you keep all the interest on Reserve. Don’t pay it, and you just lose the Reserve interest on what you spent. We also will shortly add Tokenized stocks and Crypto, and borrow against that. b) Every month you pay and top up, you get get a bigger charge card balance. Be good, get more rewards. c) Eventually, working with a partner who does external on-chain finance, we will offer unsecured credit to certain people, working within what we can/can’t do. 4/ But that’s the end game… Today >>> show we are serious about cash rewards for the membership tiers. Tomorrow >> > Charge card + Reserve cash rewards > Borrow against Tokenized everything (crypto, stocks etc) Within six months >> Full blown on-chain unsecured credit Thanks for playing… you better know we’re playing to win.

You don’t need to risk it all to get ahead. Deposit dollars. Earn 6-12%. Spend anytime. Open your Reserve account to get started.

worked with enough builders to know the real edge is knowing what failed, why, and when the same move is worth trying again. we built around one bank partner instead of stacking two. six months later they pulled back their risk appetite and we scrambled. earning the privilege to share our war stories, what worked, what failed, and what we’d do differently, so others can build better has been one of the most rewarding parts of my career.

your bank savings account is paying you ~5% right now. KAST Reserve pays up to 12% on a spending account you can use anywhere in the world. earn on your balance and spend it the same day on a card. this is what borderless banking actually looks like 🙂 Full release here: businesswire.com/news/home/2… Download and try it out here: app.kast.xyz/referral/MHTKWA…

two weeks in at @KASTxyz and the gap between what people think we are and what we're actually building is wider than I expected.. paymentscan data impressed me. then I found out it's understating the reality by a significant margin. already going deep in the trenches with people from Circle, Coinbase, Revolut, Airwallex - working on problems across dimensions nobody has touched yet. excited to share more soon.
