What Discovery Loop, Grok Bot and Lindy Got Right

Three AI startups building autonomous work tools, Discovery Loop, Grok Bot, and Lindy Teammate all launched within days of each other this week. Each one made the same promise: how to get real work done from AI without supervision.

But none of them did it the same way.

Here's how each was different, what they got right, and what founders can implement before planning their next launch.

Discovery Loop builds AI systems that run the scientific method itself: proposing an experiment, running it, evaluating the result, and iterating, but thousands of times in parallel instead of one team working through it in sequence.

The tweet doesn’t mention all that. It does say who's behind it, though: Jeff Dean, Sanjay Ghemawat, Oriol Vinyals, and Quoc Le. They have worked together for 14 to 30 years and are founding a public benefit corporation to automate machine learning, science, and engineering.

Dean left Google after 27 years to do this. Ghemawat went with him. So did Vinyals, a technical lead on Gemini, and Le, a Google Brain co-founder. The tweet's photo became the pitch: four of Google's most influential AI researchers standing together, looking like a team that has already convinced itself of the future. Google is now the new company's founding investor and its cloud provider.

The day the news broke, Alphabet's stock dropped about 5%. It was also the day Demis Hassabis stepped back from running DeepMind day-to-day to become chair.

6.4M views from people trying to figure out what four of Google's most influential AI researchers were about to build together. Intriguing, isn’t it?

The launch video opens on an office scrambling to onboard a new hire, cycling through names on a screen before it stops on one: Meet Grok Bot.

And just when you think you’ll see Grok Bot doing endless jobs efficiently, you are pulled back. The bot isn’t doing anything dramatic. Instead, you see the office getting awed by it. It watches someone work, the way a new hire would, then turns what it saw into a workflow it can run on its own. And when an employee in the video says he's always had AI as a thinking partner, just never a doing partner, it ties it all together.

Grok Bot signs in to your tools, uses them as you would, and comes back with the work done. That simplicity earned 27.1M views on a video where the most notable thing is watching people experience the magic.

Interestingly, xAI is now SpaceXAI. It just moved to acquire Cursor for $60B, and Grok Bot is being distributed jointly through it.

Where Discovery Loop said nothing about the product and Grok Bot underplayed the drama, Lindy Teammate opened with a declaration: "Today, we kill the AI agent and introduce the AI employee."

Founder Flo Crivello has been building towards this for four years.  Lindy Teammate starts in Slack, where it can absorb millions of messages in minutes, but its memory extends across meetings, inboxes, and the rest of a company's software stack. And be in multiple meetings simultaneously. That's the part of the pitch no human teammate could ever match.

The irony is that, during the same week, Crivello argued on a podcast that Chinese frontier models should be banned in the U.S. while also revealing that Lindy runs on DeepSeek by default. That contradiction never made it into the launch thread.

Lindy Teammate’s launch generated 7.6M views.
