Parrots are clearly intelligent enough to understand video UIs They also apparently prefer watching videos of other parrots 🤔 This implies an opportunity for a "parrot streaming" platform. Looking for a team who is as excited about this opportunity as Iam

Multi-agent flows in Linear are so powerful. You can take on 5-10x more ambitious tasks. I just had it build out our marketing site in 20 minutes. I will likely make minor tweaks in Cursor and ship. This was unfathomable a year ago

🔊 Excited to announce: Codegen is now GA!! 🎉 2 years ago, we set out to build an agentic developer. With Claude 3.7, it's now possible like never before - and it's absolutely killer. Build with Codegen across Slack, Github and Linear. It's transformed how we work. 👇

A 10x workflow for technical PMs & EMs: Linear inbox 🤝 code agents (Codegen ) The "inbox" is a natural queueing interface for reviewing agent outputs. Here's how to use the inbox to multi-task and effectively manage teams of agents 👇

What happens when you give a frontier agent access to a full company's history of docs, messages, tasks and more? As I'm onboarding to ClickUp, this feels like an absolute cheat code. "Cursor for your entire job." Full history of the company's thinking, decision making and operations are natively accessible w/ first-party tools and data access. No exaggeration this has reduced the amount of overhead to get ramped up (# of messages sent) by >60%. At Codegen we built an agent that straddles multiple applications - Slack, Linear, Notion, etc. - with many obvious limitations. Agents cannot search Slack historical conversations, for example, nor can you index Slack data. Any question concerning a historical decision is just out of reach. There are clear constraints of fragmentation preventing otherwise extremely capable models from performing productive tasks. Seems the biggest bottleneck to agent productivity in early 2026 is not capabilities or knowledge, it's the politics and incentives around SAAS fragmentation. Very bullish for all-in-one horizontal SAAS and what that unlocks

One of the top use cases for autonomous code agents that has been "solved" by the latest wave of capabilities (Claude 3.7): Comment Codegen on any PR with a modification request ✅ In ~1 year will feel crazy that we never had this before. Similar to better autocomplete.
