Congrats on finally earning that YC shirt, took a dozen years and just enough humblebrags to make every founder feel simultaneously inspired and mildly guilty.

Co-founding and scaling Instacart into a major consumer platform and demonstrating meaningful AI integrations (e.g., shopping agents) that translate experimental tech into real product value.

Build and scale consumer products that simplify everyday life, then use the lessons and capital from that journey to help the next generation of founders win.

Believes in shipping quickly, chasing product-market fit, the multiplier power of strong founder networks, pragmatic optimism, and that applied AI should make real user tasks (like grocery shopping) noticeably easier.

Sharp product intuition, credibility from building a unicorn, wide founder/investor network, clear concise storytelling, and an early eye for AI that sticks to real user value.

Sometimes skews insider (founder-only vibes) or leans into humblebrag territory, which can limit appeal to broader audiences; juggling founder + investor roles can scatter focus.

To grow on X: 1) Post short founder lessons and repeatable playbooks in tweet threads (real actionable value = shareable). 2) Show behind-the-scenes investor updates and founder Q&As, people love process, not just wins. 3) Use short video or demo clips of AI integrations to drive attention and retweets. 4) Host periodic AMAs or X Spaces with founders you back to leverage network effects. 5) Pin a digestible 'about + how I can help founders' tweet, and reply more to founders’ tweets to amplify community signal.

Fun fact: It took 12 years to earn that @ycombinator shirt, and he shared the victory. Co-founder @Instacart, investor, ~40k followers, ~2.8k tweets, and an early promoter of consumer AI integrations.

Super excited to work with @OpenAI on today's Operator launch — it's the first consumer AI agent I've seen that's *actually* useful...for example, it can shop on @Instacart for you youtube.com/watch?v=CSE77w

Spent the past 2 hours @HF0Residency talking to founders about the latest in AI, then a driverless @Cruise drove me home for free. It’s easy to be optimistic about SF’s future.

Using Palabra.ai is like having your own UN interpreter. It’s a mind blowing experience to have a realtime two way conversation with someone in another language.
