I've never been more proud to receive an award - because it's for lobbyists by lobbyists - for my work on behalf of @mob_advocacy & our clients. It was worth the wait for my 2020 Top Lobbyist challenge coin. Thanks @LobbyInstitute @MillerWenhold @LeadershipCnnct @StateandFederal

Happy #OpeningDay Eve. Much like parents who chose to ruin Christmas, evidently we get to open a crappy present tonight (sorry @Yankees fans) before we get to see the @Mets tomorrow. #LFGM

Happy St. Patrick's Day to those that celebrate ... For those not in the know ... Síol is Irish for seed and I chose the name to keep early-stage startups as our North Star.

They call it the 'Luck of the Irish.' We call it grit. ☘️ Building a startup isn't about finding a pot of gold; it’s about manufactured resilience. At @SiolVC, we know the best luck is built, not found. Happy St. Patrick's Day to the global Irish founder network! 🇮🇪

We’re seeing more family offices ask this exact question: if venture is now a core allocation, where does the next wave of alpha come from?

Over the past decade, venture capital has evolved from a niche allocation to a core strategy for family offices and high-net-worth investors. According to recent data, venture allocations have grown from 17% of portfolios in 2015 to roughly 31% today. https://t.co/6jDufCJjmX

At Síol, we start at the beginning - a true pre-seed fund and firm. We’re here to plant ideas and help founders grow them into something massive. Excited to share our new look that captures that journey from sprout to scale. 🌱🚀 #VentureCapital #Startups #Growth

If you distill @Siol_VenCap's thesis down to three words the would be REGULATION AS ALPHA I think I can thank a 3 hour WhatsApp text conversation with @boardyai to come up with that.

1/6 “Move fast and break things” worked for photo apps. But if you’re decarbonizing the grid or revolutionizing healthcare, breaking things gets a cease-and-desist, not a billion users. In 2026, the real upside is in the toughest markets.

After a bit of a snafu, the firm is back on @X. And now that we are close to closing Fund I, I feel better about sharing what we are building at @Siol_VenCap. Follow Síol to follow along.

People ask why we named the firm ‘Síol.’ (Spoiler: It’s not just for the aesthetic). It’s Old Irish for ‘seed.’ 🌍🌱 Because we don't just write checks: we help daring founders plant the seeds for a world-changing future. The 'Why' behind it all. 1/6 🧵

Your government just announced another billion-dollar startup initiative. Spoiler: It will fail spectacularly. Over-regulated. Over-funded. Over-influenced. The holy trinity of ecosystem destruction. Estonia gives local VCs money and walks away. Singapore backs regional

Haven't we been celebrating Armistice Day on 11/11 for many years? We call it VETERAN'S DAY since an act of Congress in 1954. Also, wasn't the Federal government usually closed on Veteran's Day? So, are we actually loosing a Federal Holiday?

Look, I probably like Brett Baty more than most @Mets fans. I think he has a future. But if I were forced to pick Soto or Baty ... no brainer.

Per Source: Mets negotiations with Juan Soto have hit a snag, because Brett Baty is unwilling to give up uniform number 22 for the slugger.
