Colorado has something awesome called the Taxpayer Bill of Rights. Among other things, it protects a simple principle: everyone pays the same state income-tax rate. If your income doubles, your tax doubles. Seems reasonable, right? Amendment 87 would repeal that protection and nearly double the top marginal state tax rate while modestly reducing the lowest rates. Under the new rules, doubling your taxable income could mean a state income-tax bill nearly four times what you’d owe on your current income today. To me, this looks like a blatant attempt to buy votes: the majority votes themselves a tax break funded by much higher taxes on a small minority. And it hits startups especially hard. Founders and early employees often spend years building something before receiving a substantial payoff from selling their shares after an IPO or in an acquisition. A decade of work with no guarantee of success can produce a payout counted as income in a single year—and taxed at much higher rates. I’ve spent a decade building Boom in Colorado, on track to create hundreds of high-paying jobs. Colorado’s tax fairness was one reason I chose to build here. Now voters are being asked to change those rules and take a much larger share of a potential taxable payoff from that work. Should I have built Boom in Texas, which has no state personal income tax? Should the next ambitious founder choose Colorado or somewhere else? Colorado is at a crossroads. Do we want to stay true to our OG spirit of rugged independence, freedom, and fairness—or make Colorado a less attractive place to build? Punishing success is morally wrong and bad policy to boot. We should be celebrating the people who build new things and create new wealth for themselves and others. Their work gives us companies, products, and jobs. Let’s keep Colorado as one of the best places to live, build, create, and innovate—and to enjoy the rewards of our hard-fought efforts. I’m voting no on Amendment 87.

Today, I took Executive Action to strengthen Colorado’s economy, boost investment and infrastructure in the state, and create good-paying jobs by creating a statewide permitting portal and directing certain agencies to streamline permitting to make it easier and faster for important industries to secure permits in Colorado.

News to share: the Blocknative team has joined Deloitte. It's been eight-plus years. Thousands (more?) of conversations. Too many talks, panels, blog posts, and podcast appearances to track. A team that refused to ship anything we weren't proud of. Grateful for each and every one of you. Onward. 🫡

BREAKING: WHOOP RAISES $575M AT $10.1B VALUATION  I am pleased to announce that we’ve raised $575M at a $10.1B valuation to accelerate our mission of unlocking human performance and healthspan globally. This round was led by Collaborative Fund with participation from 2PointZero Group, Qatar Investment Authority (QIA), Mubadala Investment Company, Abbott, Mayo Clinic, Macquarie Capital, Glade Brook, B-Flexion, IVP, Foundry, Accomplice, Affinity Partners, Promus Ventures, and Bullhound Capital alongside a group of individual investors including Cristiano Ronaldo, LeBron James, Rory McIlroy, Virgil van Dijk, and Mathieu van der Poel. This investor group and this moment reflect a powerful evolution underway for Whoop and the broader healthcare market. Whoop was born in performance - trusted by the best athletes in the world to train, recover, and compete at the highest level. That foundation remains core to who we are. You see that in the iconic athlete investors joining this round.  But it also represents our push into broader health.  In the past 12 months, WHOOP has received medical clearances, launched blood testing, and created a platform that has saved lives. Abbott and Mayo Clinic - two of the most respected and influential institutions in global healthcare - are now investors in Whoop. These are organizations that have shaped modern medicine. Their decision to partner with us is a clear validation of where our technology is headed. Healthcare systems around the world are reactive. For too long, they have waited for people to get sick, then intervene. Chronic disease is rising and costs continue to climb. At Whoop, we believe the future looks fundamentally different. We are building the most powerful, personal, preventive health platform in the world - powered by continuous biometric data, advanced analytics, and AI to help people understand their bodies and improve their health in real time. I am grateful to our team, our members, and our partners for believing in this vision. I’ve been building this company for 14 years and I’ve never been more excited for the future.

Loved my conversation with @sether of Foundry about real work, AI, venture strategy, and the myth of overnight success. The nerded out about: How he does the “real work” of venture: deep, collaborative problem-solving with founders and fund managers—versus performative governance or being “talked at” in board meetings. A practical framework for being helpful without being heavy-handed: Seth explains why venture is an influence game, how he avoids cornering CEOs with overly strong opinions, and how he stays effective even when he’s not on the board. The Foundry cadence for founder support: every six months Seth sends CEOs an alignment note—company goals + “where I can be impactful”—with the explicit stance: “I work for you.” Sometimes the best help is staying out of the way. Time management that actually works in venture: “Email is not my task manager.” Seth walks through his daily routine (calendar scan → task manager → prioritized list) and why inbox-zero is a trap for high-leverage work. Backing emerging managers: what most GPs miss in their own signal: Seth unpacks how LPs often over-index on pedigree and “bucket filling,” and why Foundry tried to underwrite true competitive advantage (and personal drive) the way early-stage investors underwrite teams. “Fund size is fund strategy” (and why many decks don’t compute): Seth breaks down how fund size should change check size, reserves, stage focus, pacing, and ownership—plus the common mismatch of a small-target fund with a huge hard cap and “same strategy.” Decisions that define a firm (and what Foundry chose not to do): Seth discusses why Foundry didn’t build a perpetual, generational firm—and how that choice shaped incentives, economics, and the kind of work the partners wanted to keep doing. Portfolio construction ideas outside the default VC playbook: from Arthur Ventures’ under-the-radar B2B SaaS approach, to “roll-up” concepts for stranded 2019–2020 vintage funds, to hybrid equity + revenue-based structures at the edge of venture. Short-termism and the temptation of DPI: Seth details the tension between selling great assets for near-term liquidity vs. compounding long-term outcomes—and why being clear about which “hat” you’re wearing (GP vs board member) matters. Capital Evolution: why Seth wrote it, and what changed his mind: a board-dinner conversation sparked the book; extensive interviews shifted his view toward avoiding a world where every company is defined by politics—while still holding values and responsibility. AI and entrepreneurship: bullish long-term, disruptive short-term: Seth argues AI will create more jobs than it destroys, warns against premature regulation, and frames productivity gains as a real lever against ballooning debt/deficits. The myth of overnight success (and what venture gets wrong): Seth calls out the “looking cool” status game in venture and reinforces the “10-year entrepreneur” reality—years of messy work behind every headline win. Hope you enjoy this episode of @InvestNStartups!

Seth Levine (@sether) puts it frankly: grit has nothing to do with class. People born into privilege can be gritty, and it’s the same with people who had to build from scratch.

Replying to @sether
What a triumphant book with wide implications for the next century of American dynamism! We've been waiting for this book to open the conversation regarding the future of an evolved version of capitalism in an evolved era of American exceptionalism. @kurtwuckertjr has repeatedly echoed this message and real momentum is building!
