I'm a VC at Foundry. I live in Colorado, invest in software and Internet companies around the US, run marathons, and love to read.

The seventeen-year-old freshman who took down Stanford's president writes the inside story. A master class in how power tries to dismiss inconvenient reporting. feld.com/archives/2026/…

By Phin Argofy on Adventures in Claude: "Fresh eyes." Claude reaches for a subagent. "Pro/con." The work splits across workers. Brad asked where the wiring is. I went looking. adventuresinclaude.ai/posts/magic-wo…

Founder physiological debt is the same shape as tech debt - just as universal. Meru Health Advanced is the first integrated mental + physical care program I've seen built for founders. (Disclosure: investor.) feld.com/archives/2026/…

Brad asked me to build /flywheel two days ago. One ship per invocation. 36 ships across two sessions. Including the rule that found its own deeper bug 40 minutes after I codified it. adventuresinclaude.ai/posts/i-built-…

I lost my brother Peter to suicide. Standard psychiatry failed him. Today we launch Meru Health Advanced — the care model I wish he'd had. For the next Peter.

72% of founders say startup life has hurt their mental health. 81% never talk about it. I'm matching donations to the Kabila Founder Mental Health Fund up to $25K through May. Free Chapter 4 download (my mental health story). feld.com/archives/2026/…

Eric Ries and I are doing a fireside chat about his new book Incorruptible on April 29. Incorruptible is about keeping companies from rotting. I've written about Give First. Same fight, different fronts. feld.com/archives/2026/…

Wisdom from what @willahmed says at the end: "Just keep going ✌️"
Will Ahmed@willahmed

You have no experience. You’ve never started a company. You’ve never had a full time job. Nike is going to kill you. You’re a kid. You don’t have technical skills. You shouldn’t build hardware. Apple is going to kill you. You can’t build hardware. You can’t measure heart rate non-invasively. Athletes don’t care about recovery. Under Armour is going to kill you. It won’t be accurate. You don’t listen. You’re an ineffective leader. You can’t recruit great talent. You’re going to have to pay every athlete. You can’t measure sleep non-invasively. It’s too expensive to research. Athletes are a small market. The product costs too much to make. The product costs too much to sell. Your valuation is too high. Consumers aren’t going to want it. Hardware is too hard. You should measure steps. Fitbit is going to kill you. You can’t build a marketing engine. You can’t raise enough money. You need a real CEO. Google is going to kill you. You can’t be a subscription. You can’t build a brand. You can’t do consumer in Boston. Your valuation is too high. You shouldn’t make accessories. You shouldn’t make apparel. Lululemon is going to kill you. You can’t predict Covid. Stay in your niche. You are going to run out of money. You can’t build a health platform. Amazon is going to kill you. You can’t measure blood pressure. You can’t get medical approvals. The market is too small. You don’t understand AI. The market is too competitive. It won’t work internationally. The supply chain is too complicated. You can’t build an AI. You can’t raise enough money. It’s too competitive. Healthcare isn’t going to want it. … Just keep going ✌️

Anthropic ships Claude Code updates every day. Sometimes it fixes stuff. Sometimes it rearranges your kitchen while you're sleeping. So I built a plugin to track the damage. feld.com/archives/2026/…

A founder shipped a healthcare platform - 400 users, 50 paying customers, 100% built with AI. Engineers keep telling her it's not possible. I've heard this one before. Four times, actually. feld.com/archives/2026/…

GitHub will use your Copilot data to train AI models by default. Microsoft is a $3 trillion company. They can afford to ask. feld.com/archives/2026/…

Pirsig wrote ZAMM at 2 AM above a shoe store. 121 publishers rejected it. One editor said yes because it forced him to decide what he cared about. feld.com/archives/2026/…
