Launch HN: Ardent (YC P26) – Postgres sandboxes in seconds with zero migration

YBacked by Y CombinatorUse coding agents on real data with no risk

Create copies of any Postgres database in under 6 seconds so coding agents can verify their code works in prod

Get startedBook a DemoStop breakages

Validate code before it reaches production

Let Coding agents test their database code on a 1:1 copy of your production postgres

Book a DemoZero blast radius

Test with zero risk to production

Each clone is isolated at both the compute and storage level. Clones never impact production. Ever

Book a DemoSpeed at scale

Cloning that never slows down even at terabyte scale

Clones load in 6s, scale to 0, autoscale compute and do not duplicate storage. Zero management needed

Let agents solve your toughest data problems without fear

Give every agent a copy of production to test everything.

Customer Impact

Built for teams moving fast with AI at production scale

“We spent hours trying to test AI database code through inaccurate seed files. Ardent lets us and our agents test in seconds with zero drift from production.”

Akshendra GargCTO Zennagents-0%Downtime+0%Release speed0 hoursSaved per releaseWhat the best say

Trusted by the best in Data

“I think AI will disrupt data engineering in a significant way. I'm investing in Ardent to accelerate that disruption!”

Zach WilsonFounder of Dataexpert.io

“Ardent is a fundamental complete shift in how agents and developers work with databases. It's as critical as git was for code”

Abhay SinghHead of Data at Chevron

“Ardent let us move as fast as agents write code. We no longer worry about our agents working on the database layer.”

Pryce YebesiCEO at Openledger

Ship fast and don't break things

Make sure coding agents never break your DB.
