Espresso AI | Staff ML & Staff Infra Engineers | Brooklyn or San Francisco | Full time

We're using LLMs to build neural optimizers, neural scheduling systems, and neural workload tuners. (If you're ex-Google, you can think of it like Borg powered by LLMs.)

Today we use ML to make data warehouses and spark jobs more efficient. We're hiring staff ML engineers to train models that can understand how much compute a job needs, how it scales to larger machines, whether a machine can run more jobs, and so on; and staff infra engineers to take those models and deploy them on real-world production systems.

If this sounds cool, please email me: ben [at] espresso [dot] ai

Show HN: Free Snowflake Observability

karamazov — Thu, 26 Feb 2026 19:19:46 +0000

My startup helps companies save money on Snowflake, and over the past two years we've built out a lot of observability features based on customer requests.

We're launching these features for free for everyone. You can read more here: https://espresso.ai/post/observability

Using ML to make SQL queries more efficient.

This is what my company does (https://espresso.ai/), I'm taking advantage of the end of year quiet time to hack on some more R&D-style projects we have.

Show HN: Optimize Databricks SQL

karamazov — Wed, 29 Oct 2025 15:02:39 +0000

I launched my startup's Snowflake optimization product here about two years ago, and we've just released our second product: a Databricks SQL optimizer.

The optimizations are basically kubernetes for data warehousing: we take over autoscaling and cluster selection to increase utilization without impacting latency. The scheduler is backed by ML models that predict runtime and capacity, which means we can run machines hotter than the providers can and thereby cut costs.

New comment by karamazov in "Launch HN: Baselit (YC W23) – Automatically Reduce Snowflake Costs"

karamazov — Wed, 08 May 2024 22:43:15 +0000

Chiming in, I'm one of the founders of Espresso AI - we do both query optimization and warehouse optimization, both of which are hands-off. In particular we're beta-testing a fully-automated solution for query optimization (it's taken a lot of engineering!).

Based on the responses here I think we're a superset of where baselit is today, but I could be wrong.

We have better tech. For our customers, this translates directly into more savings.

We also have less setup and overhead than most of the other companies in the space. many of them come in with recommendations for system changes that you need to implement, and which they then charge you for; we take about ten minutes to set up and then generate savings automatically.

The immediate next thing is expanding to Databricks, followed by BigQuery and other data warehouses.

In the long run we plan to optimize source code (e.g. C++).

there's not a lot to demo - you just turn it on and your bill goes down. I'll try to think of something we can put up though, thanks for the note.

For now I'm hoping 15 minutes is a reasonable investment to save $10k or $100k.

karamazov — Wed, 17 Apr 2024 04:27:16 +0000

Yes, for right now. We have waiting lists for Databricks, BigQuery, and Redshift; we're hoping to get there later this year.

Shoot me an email if you're interested in one of those: ben@espresso.ai.

Show HN: Save 50% on Snowflake in 15 minutes

karamazov — Tue, 16 Apr 2024 17:58:31 +0000

I'm a former YC founder, and I've been working with some friends from Google to build Espresso AI, an ML-powered Snowflake optimizer. We use LLMs to analyze and predict your SQL workload and run your warehouses more efficiently. Our first few customers are seeing Snowflake savings from 30% to 70%. We're launching out of beta, and if your team uses Snowflake we'd like to help you cut down your bill.

You can set up Espresso in under 15 minutes with the instructions here: https://espresso.ai/onboarding

Before turning anything on we'll send you a savings estimate based on your historical data. You can also get an estimate without setting up an account by following the instructions here: https://espresso.ai/savings-estimate-instructions

You can reach me at ben@espresso.ai if you have questions (or just leave a comment, I'm around).
