First Builders backing First Builders. @TheCouncilCap Angels Winter 2026 cohort is now open. Applications close Friday, Nov 20. Our community has 200+ operators leading in their fields. Our members have been pivotal early hires at companies like Figma, Square, Slack, and Lyft, among many others. They’re in the right rooms, and they know a founder who truly understands the customer when they see one. Join us for vetted deal flow, co-investing alongside our fund led by @AmberIllig & @rachtsui , high-quality networking with fellow operators and founders IRL + online, and much more. This cohort is for you if you’re: → A seasoned operator eager to add value to cap tables → Ready to start angel investing or already writing checks, and want to invest with conviction alongside other operators → Passionate about community and supporting founders We keep each cohort intentionally intimate and highly curated, so seats are limited. 📅 Applications close Friday, Nov 20 🚀 Cohort kicks off Wednesday, Dec 9

POV: our investment in @noxmetals 🔥 @zanehengsperger was buying their first saw with an empty factory, trying to convince VCs that they could scale physical operations faster with proprietary software. Now they hit $25M in annualized revenue in ONE YEAR and are inspiring other companies to do the same. If you’re building tech-enabled infrastructure in a critical supply chain, I want to hear from you *early*

Product teams ship at AI speed, but compliance still moves at human speed. Preeti Krishnan (@pkrishnan03) saw that gap firsthand as former COO of DailyPay, helping it scale from $2m to $250m ARR. So she built @leelainc for the AI era. Our full conversation >> 00:45 From writing the rules to COO 03:18 Why compliance feels like a brake 06:27 The 4 jobs no tool fully does 09:59 AI mistakes, repeated 200x 12:53 What Synapse cost its bank 15:59 Leela works while you sleep 17:48 85% automated, humans decide 21:17 Why LLMs alone can't do this 24:35 Who's already using Leela 29:44 Her cofounder was a cold DM 33:20 $4.6M raised, oversubscribed

Proud to share that @TheCouncilCap was selected by 70+ of the leading LPs investing in emerging VC as one of the top firms they want to meet at RAISE Select. I'll be there on Oct 22 in the Presidio with 330+ family offices, fund of funds, institutional LPs, etc in attendance. Excited to join and share what's led to repeated successes in our portfolio and why we're so obsessed with First Builders 😎 It takes years to bake, and I appreciate now more than ever the LPs that believed in us from day one when we had no external validation. Think that's going to pay off 😉 If we haven't met yet and you'll be at @raiseconference, reach out!

Operator capital is becoming its own craft. Enrich is hosting Tech Angel & LP Investing 101 on August 6 in San Francisco, bringing technology leaders into an approval-based room with @AmberIllig and @rachtsui of @TheCouncilCap to explore angel investing, LP investing, risk, return, diligence, and long-term value creation. The next innovation cycle will not just be shaped by who builds great companies. It will be shaped by operators who learn to allocate capital with patience, discipline, and conviction before the market agrees. #sanfranciscotech #angelinvesting #lpinvesting #venturecapital #founders
