Building production-grade agents shouldn't be difficult or tedious. In fact, over the last few months, several customers have begun sharing major agent improvements, built E2E without deployed support. The big unlock has been Duet, Decagon's AI agent for building AI agents!

[Decagon @DecagonAI]

Introducing Duet Autopilot, the first verified self-improving AI agent for CX.

It automates agent improvement by turning conversation signals into validated improvements ready for human review, helping agents get better with every conversation. 🧵

Decagon is opening an office in Toronto. 🇨🇦

Toronto has become one of the best places in the world to build AI, with an exceptional concentration of engineering talent.

We’re actively hiring across product, engineering, and GTM. ↓

We’re hosting a poker tournament with 24 top players from @cognition, @cursor_ai, @perplexity_ai, @anthropicAI, @thinkymachines, @midjourney, @tryramp, @xAI, @evidenceopen and more.

No buy-in. Big prizes. Live sushi chef, open bar, in a secret SF venue that’s never been open to the public.

Each company is sending 1 to 2 players to the table to see who can win it all.

We’ve reserved a small number of spectator spots. Register below for a chance to attend or tag someone who should be in the room.

4/ With these learnings (and more) we were able to blow the incumbent legacy IVR's 12% booking rate out of the water with a 67% booking rate, right in the middle of the most critical week for the business. To learn more DM me or check out https://t.co/95SeJp9H8l!

I spent the last few weeks at @DecagonAI building and deploying a voice agent for one of the largest tax prep companies in the world.

Here's what I learned 🧵

[Hanjune Lee @hanlee4g]

3/ Proving an agent's intelligence in the first message matters. When most customers sense a non-human voice, they assume it's a legacy IVR and communicate accordingly. For example, proactively mentioning a customer's upcoming appointment can reframe the entire convo.

We're opening an office in Sydney. 🇦🇺

We've been seeing strong pull from teams in the APAC region, especially from companies operating across large geographies, extended hours, and global customer bases.

And, we're building our team on the ground. Check the thread to join our founding team in Australia.

Excited to share Kiki, an open source chrome extension that lets you control your browser with your voice and via chat!

There is a ton of exciting work in the headless browser automation space and in new ai-native browsers. @junepyosuh and I wanted to try a different angle to bring browser automation directly into the browser you already use.

We think that there are a ton of cool use cases, and we would love to hear your thoughts and to collaborate directly on the project here: https://t.co/zd0vVLowLl. Really looking forward to seeing how we can evolve Kiki together!

@hanlee4g and I worked on Kiki, an open-source Chrome extension that lets you control your browser with voice and text.

It’s a lightweight assistant that makes the web AI-guided. You can use it to pull a specific detail from a page you've never seen before, or hand off a boring multi-step task like filling out a form, searching Amazon, adding items to cart, and placing an order.

With a lot of progress happening through browser agents and layers built for agentic workflows, we wanted to try a simpler angle. This is for people who just want to keep the browser they already have, install one extension, and talk to it.

It’s an early attempt, but we think this direction could evolve into meaningful use cases together. Welcome any thoughts/comments! https://t.co/iYyaMRaIpP
