Here we go! very excited to work with all of the great people at Databricks and make the best agents for data work in the industry

I’ve been extremely impressed with everyone we’ve met, and there’s been amazing work shipped just in the last week (KARL, OfficeQA Pro, Genie Code…).

Quotient is joining @databricks!

@freddiev4 and myself started @QuotientAI in 2023 with a dream and a hunch that the next era of AI will be unlocked by systems that can measure, evaluate, and improve AI in the real world.

Over the past couple of years, we partnered with companies ranging from AI-first startups to Fortune 500 enterprises. They used Quotient to monitor AI systems in production, ensure their agents met strict enterprise policies, and reinforcement fine-tune agents to consistently achieve double-digit performance gains.

We built it all at the bleeding edge, with a small team that started in Boston, Massachusetts.

Joining Databricks gives us the scale and resources to take this much, much further.

Very grateful to our team, investors, customers, and everyone who supported us along the way.

We couldn’t be more excited for what’s next.

Onwards!

@Hunter_Weiss sounds like you had a pretty good recovery tho. dealing with the same thing — tore my labrum back in november but only found out after a few months of pain + PT (then MRI). worth it to get the surgery then? how bad was the pain before ?

@ryxcommar @DeepDishEnjoyer they were really good. rip clover

[Yuchen Jin @Yuchenj_UW]

Can’t believe I coded by hand for 15 years.

15 years of memorizing syntax, Vim, Stack Overflow, broken builds, cursed dependencies, merge conflicts, and “one last bug before sleep.”

All of that just to end up typing “fix this” into a chat box and watching an agent do crimes.

@pnwprincess23 oh rip did not hear about cathari but the collab with Lisa was a good call

[Freddie Vargus @freddiev4]

@pnwprincess23 yeah they’ve been poppin off with the womenswear. could be the new creative director they hired

i skipped buying anything the previous two men’s seasonal releases because i just felt underwhelmed

Logged on RuneScape for the first time in a while. Map looks a little different.

@pnwprincess23 i see mystery dungeon, I like

@weareangelcity @jefrankle can we get Databricks tamagotchis

[Freddie Vargus @freddiev4]

@weareangelcity now this is what I call merch

[Ashutosh Baheti @abaheti95]

In 1945, Vannevar Bush imagined a machine to extend a scientist's memory. He called it the MemEx.

80 years later, we built one for LLM agents.

Tool outputs become Python objects; only print statements reach the model's context.

[Freddie Vargus @freddiev4]

infinite token budget if you join our team at Databricks

[Julia Neagu @julianeagu]

@freddiev4 I’m not making any promises but we can backstop the corporate card with @freddiev4’s personal one

[Jane Zhang @jjanezhang]

Julia is working on fascinating agent eval challenges and I’m excited to see how the team improves the pace at which we hill climb on all the knowledge work tasks executed by Databricks customers!

Reach out if you are researcher/eng and want to live in evals!

[Shubham Toshniwal @ShubhamToshniw6]

Can't emphasize enough the importance of continuously evolving evals. @julianeagu gets this as good as anyone. Fantastic opportunity to join our fast moving team!

[Freddie Vargus @freddiev4]

infinite tokens btw. come join our team!

[Julia Neagu @julianeagu]

I'm building a new team at @databricks AI Research and we're hiring.

We're focused on one of the hardest open problems in AI right now: how do you measure and continuously improve agents that operate on enterprise data at scale. We're looking for founding engineers to build the flywheel that turns evaluation results directly into better agents — from development and training all the way to production.

If you want to work on problems that actually matter at the frontier of AI research, I'd love to talk.

This is a fantastic team. Check it out if you want to help build agents and models that reliably answer the most challenging analytical questions in biotech, finance, etc for our customers.

[Hanlin Tang @hanlintang]

@julianeagu is incubating a new team, join her!

[Andrew Drozdov @mrdrozdov]

An incredibly exciting opportunity. Come work with us! Lots of fun and impactful problems to work on.
