- Devin Oncall launch post, quoted verbatim: "TierZero joined Cognition with the vision of a single platform autonomously handling your full SDLC. Today, we are taking one step closer towards that vision by launching Devin Oncall, your always-on AI software engineer." The launch shows the TierZero production-agent work shipped inside Devin about three months after the deal.Oct 15, 2026TierZero joined Cognition with the vision of a single platform autonomously handling your full SDLC.

- Joined Cognition as Member of Technical Staff in June 2026, when Cognition acquired TierZero, the company he co-founded with Anhang Zhu in June 2024.Jun 2026
- On X he wrote: "Excited to launch Devin Oncall today! Over the past few months, we brought all of our learnings over the past 2 years developing AI agents for production into Devin".Oct 15, 2026Excited to launch Devin Oncall today! Over the past few months, we brought all of our learnings over the past 2 years developing AI agents for production into Devin and we’re excited to make it available to all Devin customers!
- Three-month reflection on Cognition, quoted verbatim: "It's been 3 months since I joined Cognition and it's been such an amazing time working with a super talented "Avengers" team in one of the most excited spaces right now!" He listed the $48B raise led by a16z and Accel, SWE-2, Fusion in Devin CLI and Devin Voice, and ended with a recruiting call.Sep 15, 2026It's been 3 months since I joined Cognition and it's been such an amazing time working with a super talented "Avengers" team in one of the most excited spaces right now! Just last week, we announced - New fundraise round at $48B, led by a16z and Accel - SWE-2, frontier model capabilities at fraction of the cost - Fusion in Devin CLI, giving you the ability to control different models for different parts of your coding agent harness - Devin Voice, native experience to talk to Devin for your projects There's a lot of more exciting news to come and things to build, so if you're interested in trying out Devin or working at Cognition, please reach out!
- Announced the Cognition acquisition on LinkedIn, quoted verbatim: "We're super excited to announce TierZero is joining Cognition! The past two years has been an incredible journey with our team, investors, and customers and it's hard to put into words how grateful I am with all of the trust they all have given us." This dates the TierZero exit to July 2026, about two years after founding.Jul 20, 2026We’re super excited to announce TierZero is joining Cognition!

Cognition builds Devin. Devin plans, writes, tests, and ships production code on its own, working inside your codebase and the tools your team already uses. Devin is deployed at some of the largest and most complex institutions in the world.
Acquired by Cognition. TierZero is an AI platform that helps engineering teams run production systems reliably at scale. Our agents automate incident response, surface reliability risks, and give engineers instant answers to production questions.
Databricks is the leading Lakehouse Platform. It unifies your data, analytics and AI and enables you to use it to power agents, apps and natural language insights.

Not to mention all the internal work we're doing on the quality of our agents (agent evals, proxy MCP arch for context management, and adversarial agent teams). Excited to continue innovating and shipping for our customers!
Developing software has changed completely over the past 6 months. Come join us to redefine how you run your code in production here at TierZero!
LangSmith has given the visibility into our AI agents that have enabled us to deliver and improve TierZero at lightning speed. Not only that, we've integrated TierZero itself to LangSmith as a data source to auto-improve our agents real-time! Excited to continue to partner with
One thing our engineering team keeps running into is that when we use coding assistants like Claude Code and Cursor, which we rely on heavily, we often hit a wall when we need real production context. These assistants are great at reasoning over code, but they’re mostly blind to
