Sam Altman, OpenAI CEO

Sam announced an updated OpenAI-Microsoft agreement: Microsoft remains the preferred cloud partner, but OpenAI can now deploy products and services on any cloud rather than being exclusively tied to it. He promised continuing updates on the terms. The post received 13,164 likes, making it one of the day’s most widely circulated AI stories. He also expressed joy over GPT-5.5’s release, saying builders finding tools useful is what gives him the greatest satisfaction. He specifically called Codex included in the $20 plan “an incredibly good deal”; its entry into the mass market at this price is worth watching.

Aaron Levie, Box CEO

Aaron identified a cognitive bias: an “AI version of Gell-Man amnesia” is spreading. When using AI for their own work, people clearly see last-mile problems requiring human intervention, yet assume AI can fully replace others’ work. This asymmetry systematically underestimates indispensable human contributions and deserves attention from anyone planning AI products.

Amjad Masad, Replit CEO

Amjad announced Replit’s official entry into Canada. He also emphasized that Replit solved the full agent production-isolation problem more than a year ago and is currently the only platform with this capability, predicting growing advantages for vertically integrated platforms. He previewed a new project: 20 builders, 8 weeks, with the goal of earning their first revenue.

Peter Steinberger, OpenClaw Founder

Peter released three tool updates at once: (1) `birdclaw`, a local tweet archive that imports Twitter archives, backs up automatically to GitHub, and periodically syncs X bookmarks; (2) faster testing by moving OpenClaw’s local tests to Blacksmith, using instances up to 32vCPU to reduce CI time substantially; (3) `wacrawl 0.2.0`, supporting encrypted Git backup and restoration of WhatsApp desktop archives, storing age-encrypted shards in GitHub with one-click pull, decryption, and restoration.

Garry Tan, Y Combinator CEO

Garry reflected on “talking to books,” describing the surreal experience of AI letting a book know you and converse like a friend. He also shared a personal agent configuration: OpenClaw knows his full schedule and health goals and refuses requests after 12:30 a.m. to enforce sleep. Most notably, he shared a three-file framework: `SOUL.md` defines identity, voice, values, and principles; `CONTEXT.md` holds live knowledge, current goals, priorities, and ongoing projects; `TOOLS.md` lists capabilities and access methods. Their responsibilities are clearly separated.

Nikunj Kothari, FPV Ventures Partner

Nikunj launched “Dawn” with Thariq of Anthropic and Varadh, a community for former founders after exiting entrepreneurship. Every startup stage has communities, he argued, but life afterward lacks a dedicated sense of belonging and place to connect. Dawn aims to fill that gap. He also said solving genuinely difficult problems will remain messy and uncertain even near AGI.

Dan Shipper, Every CEO

Dan shared the judgment that “as the cost of producing code approaches zero, software becomes the new media,” previewing a Betaworks talk on the theme. He also shared his reading list for the year, showing broad interests.

Peter Yang, Roblox Product Manager

Peter summarized 5 lessons from independent AI founder Tibo, who earns over a million dollars monthly: (1) charge from day one rather than be free to look successful; (2) start small instead of trying to do everything; (3) prioritize retention over growth; (4) distribution matters more than product; (5) use AI for automation, not features. He also built an MCP server for his fitness app, letting Claude and Codex query current workout data and update training plans in real time.

Aditya Agarwal, South Park Commons Partner

Aditya announced that Snowflake CEO Sridhar Ramaswamy will visit South Park Commons next week; he previously grew Google’s advertising business from $1.5 billion to $100 billion. Aditya also shared Bevel 3.0 updates, stressing that its long-term goal was never to be a tracking and analytics company, but “the smartest health and biology companion that truly understands users.”
