Using Claude Code to build apps is fun until real people start using them, making feature requests, and reporting bugs.
Suddenly, you and Claude aren’t enough to keep up.
From Mars to Brazil, @inazarova.bsky.social took over the Tropical on Rails stage for 5 minutes to address this. 🧵
No one could actually explain what PMF is or how to find it... until @inazarova.bsky.social conducted thesis-grade research on 35+ successful devtool companies.
She built a PMF compass that tells you exactly what to do next based on where you are.
We work with ~40 early-stage startups a year. Most founders confuse product-market fit with signups, but these are a vanity metric.
We recently studied 25+ successful devtool businesses and found exactly what they're missing to get PMF.
We're ready to share findings with you. March 23rd. 👀
Just updated the final speaker lineup on our site. This conference is taking off!
@inazarova.bsky.social and I had a chat about the @sfruby.com! We go deep into venues, marketing, and so many more conference details. Check it out!

Hey there, the next #SFRuby meetup is *today*, hosted by Persona 💙
Here’s the plan:
5:00 pm doors open, refreshments, and the latest ~rumors~ news.
The second batch of talks from the 2025 SF Ruby Conference is now live on YouTube.
This features demos and presentations from the Black Box Theatre stage, with @indirect.io, @inazarova.bsky.social & Albert Pai, @bensheldon.bsky.social, and more.
Watch them in order: www.youtube.com/playlist?lis...
2. new open source in Ruby/Rails ecosystem (including your wild experiments and new ideas in established open source projects)
3. real stories from Ruby/Rails apps and teams, solving complex, tricky, or fun problems
And it needs to be about Ruby, and in-person in SF!
Friends, we're meeting on January 22 for the next #SFRuby meetup at Persona HQ! I hope to see you there! We're looking for talk proposals! We are doing 10/20/30 minute presentations. Our preference:
1. demos of new and ambitious Ruby startups (just tell us what you're building with Ruby!)
My favorite talk!! @jpcamara.com used Yjs and @anycable.io to build a collaborative text editor in a Rails app, and it was super fun trying it out live with other folks during his talk.
To celebrate the 30th anniversary of Ruby and the release of Ruby 4.0, the first 32 talks from the SF Ruby Conference main stage are now live on YouTube!
This includes keynotes from @marcoroth.dev, @palkan.bsky.social, and @paolino.me. We’re working on uploading the rest next week.
@sfruby.com (#sfruby) was a huge success 🔥
Huge thanks to @inazarova.bsky.social for bringing the community together and to @evilmartians.com for supporting this initiative from day one.
Grateful to every coordinator and to the volunteers who supported this event from behind the curtains.
Friends, the recording of the #SFRuby meetup in October at AngelList is live! Inside are talks on Zaxcel (Ruby DSL for Excel files), writing Rust extensions for Ruby, secret management with dotenvx, LiveComponent, and AI-backed domain logic in Foobara.
The next SF Ruby is this Thursday, hosted by our friends from Intercom, and we'll talk about Ruby 4.0 (of course!), one yummy JS runtime i(n a gem), and the ideas on building AI libraries for Rails. Join in! luma.com/sfruby
“The promise of Rails is being fulfilled. People just haven’t caught up with this reality yet,” says @inazarova.bsky.social.
We wrote about SF Ruby and reveal the real reason we decided to host the conference.

We see a surge of leads looking for "vibe code cleanup". So, at this point, we're out to make vibe coding more efficient!
@inazarova.bsky.social experimented with vibe coding while building a feature for @sfruby.com’s website, but it wasn't perfect.
@sfruby.com Day 3 was the perfect community break!
Started with a Lucasfilm museum walk (thank you, @inazarova.bsky.social), then joined the Golden Gate Bridge bike tour with @kanejamison.com, @jpcamara.com, @jeremysmith.co, @adarsh.ruby.social.ap.brid.gy and so many amazing Rubyists.
thank you! this is very kind. I'm really hoping we can do this again!
Such a great post about @sfruby.com from the brilliant @chael.codes !!! Got to admit, my mind was all over the place as we ran the conference for the first time ever-I was worried if everyone felt good. I'm so happy to read all the feedback and posts!
Back home from a fantastic @sfruby.com conference and 10 days in San Francisco. A packed schedule of talks, hack day at #angellist and many great conversations. The #ruby community really still is something special. Thanks @inazarova.bsky.social and team who put in so much in to make this happen.
And thanks @paul_ionut_bob and @paolino for a cool day.
Thank you, Ruby ✌️
SF was a blast. 🌁
Vladimir on stage next to the opening slide which says "Rails" and then has a big X railroad crossing.
Brittany Martin, Amanda Kinney, Gary Tou, and Irina Nazarova standing behind a half-eaten cake that's half-vanilla and half-chocolate.
A cake with railroad tracks and a fondant train on it in the entrance.
There was a fun surprise after the closing keynote, a Rails X cake!!
