Sort of telling with buyback authorizations re: how companies think of their future. In a world where every pure SaaS company is at an all time high disruption risk, you’d think that money might be better spent on creating AI native experiences #AtomsNotBits

Most data teams are still building dashboards nobody looks at. We killed 1,400 of ours. Replaced them with a semantic layer you can talk to. Built custom AI tooling that replaced SaaS we were paying six figures a year for. Every person on this @Opendoor data team has unlimited

We just went live in production on a new feature. It was a busy day but nothing feels as good as shipping products.

One of the most underrated things about AI driven automation. Mistakes are easy to fix. We had a bug in our assessment process yesterday. 3 months ago, that would’ve meant 2am pages, lot of overtime and delayed offers. Today we basically just hit ‘retry’ after a fix.

For anyone in a software engineering leadership/management position, this is the time to see if you can figure out how to shelve that responsibility for a while and return to being a full time IC. Software engineering has changed more in the last few months than it has in the

We’re doing a fun thing @Opendoor a lot more recently. Instead of beleaguering folks - esp founders - with typical tech interview loops, we’re just building in person together. 2 weeks of side by side crafting, focusing on delivering customer value.

Related - we shipped a pretty meaningful change to how we work over the last few weeks. Many internal productivity asks around access, enablement etc all get served by agents with policy docs instead of people - enabling us to stay laser focused on enabling product velocity.

One of the most important decisions we continue to make day in and day out at @Opendoor is to bet on the partners that we think deserve to win in the ai-native landscape of tomorrow. Apps that enable agents > apps that are perfect for the needs of today

Or @Opendoor. Use all the tokens you could possibly want.

At YC, we let our engineers let it rip. There is no limit to the number of tokens you get. If you're at a place that is stingy with tokens, and you have that need for a speed, come to YC and let it rip. https://t.co/oYI6ze7Pz7

For the first time in many, many years, Opendoor’s core workhorse is on a modern version of Rails. Monoliths and monorepos are the most AI-friendly way to move #faster

I sent this to all of our engineers on my third day at @Opendoor. It genuinely may be my single most important contribution to our long term success thus far.

One of my favorite things about working with our team at @Opendoor is how deep in the craft we are from top down- no task is ‘beneath’ anyone or ‘not their job’. @yang_guo values homes. @morganb is spinning up new campaigns. The engineering leaders do on-call(and still build)etc

Hire out of pain. Don't hire because you think you'll need someone soon or maybe sometime later. Wait until you or your team are actually hurting: working weekends, missing family dinners, dropping balls. That pain is the signal that the role is real. I learned this the hard way

I saw a guy coding today. No Okara. No Cursor. No OpenCode. No Claude Code. He just sat there, typing code manually. Like a psychopath.
