great writeup by @pirroh
harness doesn't disappear as models get smarter - it shifts from deciding to offering
in deepagents you give each subagent its own model, tools, and permissions - the main loop picks which to spawn and when

I'm thrilled to announce that @Replit has acquired @attaapp, bringing our world-class AI analytics to everyone.
Two years ago, I cold emailed @amasad asking him to invest in Atta.
He and @pirroh saw an early demo of our charts and data apps on an infinite canvas and wrote a check the same day.
@aminert and I founded Atta to democratize business analysis.
We empowered the people closest to the business problems to understand their data, communicate their insights, and make better decisions.
No SQL. No cleaning up AI slop. No picking the right analytical method, the right visualization, or even which model to use at what effort.
You simply connected your data and we took it from there.
Earlier this year, two public companies ran their Q1 QBRs on Atta.
At one of them, the top 50 execs replaced their SaaS tools with decks and docs built in Atta, connected directly to their data warehouse.
We're excited to continue our mission at Replit, where it will reach business leaders everywhere.
Joining Replit means the world to me.
I grew up in a low-income, immigrant community outside Chicago where nobody knew anything about computers, so I taught myself.
I wrote my first line of code on Codecademy in 2012.
My mom still remembers me running over to show her a Python function that passed all its tests.
When Replit came out as a cloud-based terminal, it was the perfect place to practice coding challenges with my younger siblings, both software engineers now.
(I later realized Amjad also built Codecademy before founding Replit!)
Learning to code pulled my family out of generational poverty even though most people had already written us off.
Thank you to our families for patiently enduring the joys of startup life.
Thank you to our team and advisors who helped build Atta along the way.
Thank you to our customers who trusted Atta with their highest-stakes decisions.
Thank you to @MenloVentures (@mejoff, @shawnvc ), who supported us from inception to design partners to our first annual contracts.
And thank you to Amjad and Michele for the opportunity to continue pursuing our dreams.
After we pitched Atta, Amjad suggested we co-work from the Replit office.
We're here now, and we're loving it.

Some of the faces of Replit. Not just the team, but their families too.
Behind every late night and every launch there's a partner, a parent, a kid who made room for it. We’ve come a long way together, and today I want to thank you in public 🧡
A day at the roller coasters felt fitting. Two years ago this week we launched Agent 1. It has been a ride ever since🎢

We just shipped Replit to my home continent 🇪🇺
I’ll be in Europe in both October and November to talk about everything new we’ve built. See you there!
Replit is officially in London. 🇬🇧
As we open our first international office here today, we’re honored to mark this important milestone with @MayorofLondon, Sadiq Khan and his team, His Majesty’s Government, The Lord Mayor’s Appeal and London & Partners.
London will be the hub for our European operations as we expand our work with small businesses and enterprises, helping more people turn ideas into working products with AI. The city's deep talent, diverse skills base, universities and base for leading AI companies made it ideal for us.
We are also partnering with TLMA which supports young Londoners not in education, employment or training (NEET) on a pilot for upskilling.
This is just the beginning. We’re here to build in London and build with London!

Free Mode on Replit is way more than a business strategy.
It’s a career dream I’ve been chasing for years, finally realized.
Here’s how I got here:
The greatest inventions end up in the same place: in ordinary hands, doing extraordinary things.
For 20 years, President & Head of AI Michele Catasta chased this vision. Now, he's built it. This is the story behind Free Mode.

I still remember the day Michele (aka pirroh@) became a full time member of Replit instead of just an advisor. Or, in his words: "stopped just yapping and came to get things done".
Game changing since day 1. Awesome to watch you do your thing @pirroh.

Yesterday made it one year since I joined @Replit. I keep trying to summarize it and failing, because no single thread captures it.
I’m beyond grateful to be part of this incredible journey and couldn’t ask for a better team. @pirroh and @amasad are two of the best leaders in Silicon Valley, and getting to help them build toward 1 billion software developers is the privilege of my career.
Grazie @pirroh for believing in me and letting my creativity (insanity) flourish under your leadership.

What looks like an overnight success is usually years of conviction that nobody else could see yet.
@amasad and @HayaOdeh believed software creation could be radically more accessible long before the rest of the industry caught up, with @pirroh’s early vision for AI helping turn that belief into the @Replit we know today.
Now everyone is chasing the future they helped define. It’s a privilege to be part of the journey 🚀

Seriously impressed with the results using GPT-5.6 Luna max thinking with @Replit.
Built a custom design system and then published a personal Agent Knowledge Graph app for a couple of bucks absolutely no problem. Insane how much you can get done.
@pirroh was right - this is "intelligence too cheap to meter."
