Your job as a startup founder is to find ways to innovate on distribution strategy as much as you innovate on product strategy.

The best NYC mayor endorses Cuomo and I couldn’t agree more
Four months ago I endorsed @AndrewCuomo because I thought his management experience and government know-how made him the best choice for New Yorkers. I still do. And today, with early voting underway, I wanted to reiterate my support for Andrew Cuomo. Being Mayor of New York City is the second toughest job in America, and the next mayor will face immense challenges. Andrew Cuomo has the experience and toughness to stand up for New Yorkers and get things done. I hope you will join me in supporting him.

Highly thought provoking article by @AmyDMarcus as she wore a suit created by @MIT_AgeLab to simulate being 80 years old. Great insights on longevity and having empathy for the elderly. Lots of opportunities for builders in this space. wsj.com/health/wellness/mit-…

This is a massive for @Stacks👇 "sBTC and STX will be deployed on Solana and Sui using NTT’s burn-and-mint mode, creating a unified supply that is managed and maintained across all supported chains with no wrapped tokens. This eliminates liquidity fragmentation, allowing for users to participate in Bitcoin-native DeFi on multiple chains while maintaining the security and decentralization advantages unique to the Stacks L2."
Stacks 🤝 Wormhole $sBTC and $STX are going natively multichain with Wormhole NTT. Wormhole will integrate @Stacks to take $1.5 billion in sBTC and STX multichain, starting with @solana and @SuiNetwork.

SIP-31 gives @Stacks the one thing it’s always lacked: a real budget to match its ambition. @jsadlowe, CEO of @signal21btc, shares why he’s voting yes, and why SIP-31 is a long-overdue catalyst to solidify Stacks as Bitcoin’s leading L2. 👇

I care deeply about Bitcoin innovation. Amid all the noise, @Stacks and @Muneeb have consistently proven themselves as top Bitcoin innovators. Stacks’ new SIP-031 treasury management framework sets Stacks up for growth. Over half a billion dollars in Bitcoin is already deposited into Stacks. That's real capital flowing to where infrastructure actually works. Stacks L2 provides fast transaction speed, and manages to maintain 100% Bitcoin hashpower security. Layer 2 technology combined with a new treasury will allow stacks to compete with the largest chains. At @drapervc we are looking forward for the positive impact this will bring to Bitcoin DeFi - with @ZestProtocol leading the charge. I’ve said it before and I’ll say it again… the gravitational pull toward Bitcoin is real. The Stacks community is voting mid-June. Early support looks strong and I will be voting Yes.

Here’s to everyone trying something new 🫡
Frank Slootman: “There’s lots of people in this world who are not really in the arena” Frank comments on why he opens his book with Theodore Roosevelt’s famous “The Man in the Arena” quote: “There’s lots of people in this world who are not really in the arena. They are either observers, consultants, agents, or VCs that provide capital. But there are some people who are in the arena, and they are very very special people.” Frank is frequently asked to speak at elite business schools, and when they invariably ask for his advice, he responds: “You all have elite educations… you’ll have many job offers paying you big bucks. Your parents and your siblings will be incredibly proud of you. But they’re all consulting jobs for Bain, McKinsey, and companies like that… You’re going to have an easy path to pretty quick earnings, but you’ll never know whether you have what it takes [to build something new].” In Roosevelt’s words, you’ll be “those cold and timid souls who neither know victory nor defeat.” Full quote from Roosevelt’s speech: “It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.” Video source: @FoundationCap (2024)

Tough day. As an investor in @ALEXLabBTC and an affected user, I’m disappointed—but not disillusioned. Security is still the hardest problem in crypto (especially when you have meaningful TVL). Innovating on Bitcoin is even harder. I know the ALEX team. They’re owning the issue, moving fast, and making users whole. I’m still bullish on Stacks, sBTC, and the future of Bitcoin DeFi. It’s a long road—but it’s the right one.
