Excited to announce the Cosign Awards: celebrating exceptional people, companies, and products that had a massive impact in 2026.

cosign.co/awards

Anyone can nominate and vote. Award winners will be chosen by the public in conjunction with a panel of judges, including industry leaders like @lennysan, @packyM, @amasad, and many more. We’ll host an event in December honoring the winners (10 per category).

For people categories, we’re mostly focused on everyone except the CEO–everyone else building the company behind the scenes.

Companies with the most amount of people nominations will be listed on our “Top Companies to Work For” page.

True to form, at Product Hunt I helped launch the Golden Kitty awards a decade ago to recognize great products. Soon after I launched the Rise Awards, honoring executives and ICs building companies that make them. The Cosign Awards is the next iteration.

People categories:
- Future Founders

Breaking: Meta Chief Strategy Officer Dave Wehner to join Fireworks as CFO.

I announced earlier this week that I am leaving Meta. I am deeply grateful to Mark Zuckerberg for showing what a truly founder-led company can achieve. I am incredibly optimistic for Meta’s future.

At Meta, I was able to witness the most exciting opportunities in enterprise AI. That’s why today, I’m announcing that I will be joining Fireworks as CFO. I am thrilled to be joining a founder-led growth company where I can roll up my sleeves and put my experience to work.

Fireworks has the right mission for the moment. Companies will use AI to build on what makes them distinctive: their data and expertise. Specialized intelligence gives them a way to capture those advantages and own their “alpha.” Open models offer price points that allow the technology to have the greatest impact. Fireworks is building the platform to make all of this possible.

I’ve known and respected Lin @lqiao for a long time. As I’ve spent more time with her and the people at Fireworks, I’ve become increasingly bullish on what they are building. There’s a remarkable depth of technical talent here, coupled with a very practical focus on what customers need.

I see AI as the most consequential technology shift of my lifetime. I’m excited to get to work and help build a business at the center of it.

My dear friends, I’ve got 3 pieces of news

First off, I’ve retired from @midjourney after 3.5 years. It’s been an honor; we've pulled off great projects, and a few open-sourced pieces like Pretext & Handwired have been well-received. I’d do it again with the team, but they’re in a great stable place now and I planned to take >6 months off

Second, unfortunately the words spread. Life comes at you fast and (this is a crazy story best told in private) I was taken hostage by the good folks at @coreauto. I started last week. Retirement will have to wait for another few years

Third, I’ve figured out a few pieces of technology I wanted to exist for a while now. Some more like Pretext, some more like Handwired, and a mysterious new thing (pic attached. First one to guess right gets a repost). Stay tuned as we start training these at Core Auto.

We’ll show the world what AI can truly achieve in the hands of kind, capable & grounded folks who choose to look up.

P.S. we’re hiring one (1) backend engineer. Only requirement is showing us your previous project’s dependencies list

Been a really fun few months at thinky, the focus on fundamentals and scalability sets us up well for the future.
Particularly enjoyed all the work that went into the long horizon capabilities and in bootstrapping many of them from ~0 pass rates!
