Why ChatGPT Doesn't Know Your Startup

A developer tested 48 AI-native startups to measure how language models recognize brands by name versus by category. A model without web access correctly described only 4 of 48 startups by name, while a search-grounded model surfaced 28 of them when asked for the best tools in their category. The post identifies three main causes for name invisibility—training cutoff, generic names, and sites that render only in browser JavaScript—and recommends Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO): serve a plain category statement in the page HTML, add third-party mentions, and fix crawler readability. The author also describes Tabkeel, a checker that runs an AI mirror to test how a site is read and whether it surfaces in category queries.

Flue 2 Adds React-style Agent Hooks

Fred Schott, creator of the Astro web framework, has released Flue 2 — the first stable release of his agent framework — built around React-style "Agent Hooks" authored in TypeScript. Flue 2 provides 16 built-in hooks (including useSkill, useTool, useSubagent), a harness-based architecture for hosted agents, and is built on top of the open-source Pi harness. Schott positions Flue as an open-source, host-portable framework (while noting competitive overlap with Vercel’s eve), and says Flue leverages Cloudflare tooling after Astro’s acquisition by Cloudflare earlier in 2026.

Decagon Hits $100M ARR, Rejects Forward-Deployed Engineers

Decagon, an AI customer service startup led by CEO Jesse Zhang, told the reporter it has crossed $100 million in annualized revenue. The three-year-old company differentiates itself by avoiding reliance on forward deployed engineers (FDEs), arguing that a product that’s quick to customize and requires minimal services wins enterprise customers. The article positions Decagon against larger competitors — named Sierra (with CEO Bret Taylor) and Salesforce — noting Sierra has surpassed $200M ARR and Salesforce’s Agentforce exceeded $1B ARR and that Salesforce agreed to buy Fin (formerly Intercom) for $3.6B. Decagon’s investors include Bain Capital Ventures, Accel, and a16z.
