I’ve used @DevinAI for 1.5 years and just discovered you can drag multiple sessions from the left nav and view them side by side?!

Loved this honest trip down founder memory lane with @JeffreyChernick We hit some of the hardest questions I faced over the years. When should you sell your company? How do you evaluate building or buying new products? Was I the right person to be running Splice 8 years in? I also shared some deep stories of losing my father while running Splice, leading during COVID, losing my home in the palisades fire while running SuppCo. Along with some experiences that have most impacted views on religion and life as a whole. Lot’s of emotions in this one and views on the impact of AI from over a year ago. Full podcast on youtube.

I've been using the website saved as a PWA to my home screen for months. Can't wait to see what this unlocks.

I’ve been a user and fan of Devin since March 2025. Incredible to watch the progress to date and you can feel the acceleration. Congrats on the milestone.
Cognition has crossed $1B in annualized revenue run rate. This milestone belongs to our customers. Here's how a few of them are building with Devin.

Time to 'think different', it's not just an iOS simulator in the cloud it's a full Mac with iOS, tvOS, CarPlay and a web browser you can drive. You can build and verify end to end, you can take over and control, and you can do it from anywhere.
Special delivery: Devin just got a Mac 🍎 Now Devin can: 1. Build & test apps on its own Mac VM with iOS simulator 2. Send a screen recording via Slack 3. Send a TestFlight link so you can start using it 📲

This is the way
I've become extremely cloud agent-pilled. I still haven’t setup my laptop for local development since joining Cognition and it’s still unclear to me when I will have to. Working with Devin in Slack (with coworkers) and the webapp with the latest crop of models is better in every possible way so far, even for frontend work

Tragic, @JoshuaBaer was a friend and mentor. He will be missed.

I’m in the top 200 @cognition / Devin users. At $400m+ ARR,the enterprise contracts must be large and concentrated. I’m a huge fan of the pace of innovation, the multi repo support, automations, Devin review, wiki tools, computer use and now it can run and test android apps. The pace we can move at with @joinsuppco is unmatched so far. Check it out.

One thing I love about using Devin is its ability to continue to work on the pull request it submits. I have multiple agent reviews and it can monitor them, resolve real issues and push back on things it knows were intentionally my spec.

Partners through it all #)
Steve @smart is a generational talent. He is the best consumer founder I have ever known. From @GroupMe to @splice to @flybladenow and now @joinsuppco, he builds category defining companies loved by tens of millions of people. The scale and breadth of his impact is truly profound and awe inspiring. He's also a standup human being, infectiously charismatic, and I am enormously lucky to be his Partner and watch him thrive throughout the years. A huge congratulations to the entire team at SuppCo on their acquisition by @function. This is the culmination of years of hard work. No doubt that together they will continue to transform the world of supplements and help people everywhere take charge of their own health outcomes.

Really excited to be an investor in @getcasa. This is a dream service I wish I had when I was a home owner. Also proud of @miz for his incredible career and taking the step into being a founder. He started at @GroupMe as an intern and was one of the most delightful teammates I've ever had.
After two years of building under wraps, today we're announcing Casa – your personal property manager. We've raised $27M to redefine the homeownership experience from the ground up. We believe your home is your most treasured asset, emotionally & financially. It shouldn't also be a second job. Most homeowners are on their own – expected to have the time, expertise, and relationships to keep things running. Finding a plumber you can trust. Remembering when the HVAC was last serviced. Knowing what's actually wrong before someone shows up to fix it. Casa gives every homeowner what used to be reserved for the few: a dedicated team that knows your home deeply, handles the work, and stays in your corner. We're enabling this by building a deep, technical understanding of every home we serve – something that's never existed before, across 100 million single-family homes in the country. For $199/mo, membership includes: - A complete inventory of your home, built using specialized hardware & software - 1.5 hours of handyman time every month (and it rolls over) - Unlimited Concierge requests to take on virtually any home project - Custom, proactive care plans built specifically for your home - Weekly package and donation pickups - Scheduling and payments for your regular vendors - Utility and property tax monitoring …and we’re just getting started, with more benefits on the way to make the experience of owning your home as magical as it always should have been. Available now in the SF Bay Area and Los Angeles. Reserve your spot everywhere else. → getcasa.com

V2 of @heyglif is powerful, intuitive and really fun to build with. Go be creative!

Create ads, marketing content, films, short form content, voiceovers, music, and more. All in one conversation. Easy to start, endlessly deep. We're also announcing our $17.5M seed led by @a16z and @usv. Creatives: You're not cooked. You're the chef now.

Glad to see @g_rant__ taking the product lead role at @krea_ai. He was an early thinking and builder in the creative AI space and will make a big impact with this team.
big news... @wand_app is being acquired by @krea_ai, and I've joined as Head of Product along with the Wand team. more than any other company in the space, Krea shares our mission to help serious artists & designers bring ambitious projects to life without compromising their vision. to do this, we need tasteful, controllable models working in tandem with interfaces that go beyond the prompt box and reward artistic skill + vision. extremely excited about what we'll ship over the next year :)

This was a huge hit at family Christmas, reminds me of the year we got a Wii. We started with Chop Chop and the family exclaiming “more tomatoes!”, “VIP order up!”, “Clean, Clean, Clean” has led to lots of laughs.

Great conversation with @JoeVennare on @fittinsider about building @joinsuppco and the challenges in the supplement industry. We discussed our 29-point TrustScore system, balancing science with personal experimentation, and why transparency matters when 74% of Americans take supplements. Thanks for having me on to share our mission of making sense of supplements. 📷 Listen to the full episode: insider.fitt.co/297-steve-ma…
