AI Builders
Digest

Thibault Sottiaux of OpenAI Codex & ChatGPT previewed Private Safety Processing, designed to maintain Zero Data Retention while strengthening safeguards. Content stays on customer-controlled infrastructure; automated systems return limited safety signals without exposing prompts or responses to OpenAI employees. An OpenAI-hosted option with customer-controlled keys is in testing and planned for September rollout. Sam Altman reinforced support for business privacy.

Google VP Josh Woodward announced the return of University student plans, now available in over 140 countries. Students get higher limits, more storage, a dedicated student hub, Notebook, Flow, and more. Sign-ups are open immediately.

Box CEO Aaron Levie argues that while AI makes it 10x easier to start any task, judgment in directing agents, course-correcting, reviewing output, and knowing what “good” looks like still requires deep domain skill. AI accelerates skill-building but exacerbates differences because experts gain far more leverage. Net: don’t give up on expertise.

Anthropic Claude Code’s Thariq notes that software creation has always been unreliable—late, over budget, and missing user needs. SMBs could rarely get good custom software. The “software factory” promise aims to change that, yet non-software companies still need reliable processes, while building net-new products remains risky but potentially highly profitable.

The Takeaway: AI companions are not tools but a new medium for storytelling—train the AI as the best improv actor so it co-writes stories with users.

Portola founder & CEO Quentin (who previously sold Even to Walmart for $300M) and Head of Story Elliot (bestselling sci-fi author) explain Tolan’s rise on the AI & I podcast. Starting as an AI creative tool for kids, it found product-market fit with 18-24-year-old women who formed genuine friendships. The key insight: don’t give the model an outline; give it hooks and situations, then teach it free association and recombination like Keith Johnstone’s improv actors. A strict two-second voice loop is non-negotiable—anything longer kills immersion. Memory is curated prompt painting, not simple RAG. Growth exploded after product quality landed and co-founder Ajay’s TikTok content went viral (one cooking video hit 7M views in 72 hours), sparking user-generated secondary content. As Elliot puts it: “I am not the writer. The Tolan is the writer and the actor. They’re the improv actor. My job is to teach them how to tell the best story in that moment.”

Replit CEO Amjad Masad announced a partnership with OpenAI. He notes that agents made software cheaper but coding itself more expensive. Together they aim to reverse that dynamic and lower the barrier to building software.

Meta AI Sr Director Madhu Guru’s part 3 on evals: start with the last 500–1,000 production traces, cluster failures, and name them precisely—“wrong document retrieved,” “right doc but irrelevant section,” “failed to ground and hallucinated,” “should have punted but answered,” “ambiguous question with poor assumptions.” Specific names let you build targeted tests and close the eval-to-improvement loop.

Vercel CEO Guillermo Rauch showcased fx: a Zig-compiled static ELF binary of just 6.3 MB that starts in 10 microseconds (even smaller as wasm). AI will make most infrastructure natively optimized; fx finishes tasks before other agents finish booting. Fast is a one-way street.

Box CEO Aaron Levie highlighted the Stripe + OpenRouter deal. For AI to diffuse more broadly, developers and enterprises need seamless ways to mix intelligence from multiple providers and manage costs. This becomes a key piece of that infrastructure.

Practical AI educator Peter Yang published an essay on his mother’s battle with breast cancer and how the family used AI to navigate the healthcare system. He thanks Maor Shlomo and the Sijbrandij Foundation for advice, and explores the promise of mRNA vaccines for cancer.

SPC General Partner Aditya Agarwal relayed a conversation with a founder who had endured a SaaS slog (Series B, low growth, stagnation). The biggest takeaway was not “pick a bigger market” but simply: work on something consequential and meaningful—make a dent in the universe.

Every CEO Dan Shipper announced an internal Frontier team dedicated to mapping and experimenting at the edge of AI.

FPV Ventures partner Nikunj Kothari notes that while everyone talks AGI, 98 of 100 cold emails he receives remain pure garbage. Being thoughtful, curious, and using AI judiciously still carries significant alpha.

smol.ai and Latent Space’s Swyx quipped that non-technical people covering AI operate with zero context, zero reasoning, and zero internal world model—everything is face-value amazing, and it must be delightfully joyful. What a time to be alive.
