ABOUT

Built on 100B+ S3 requests/month of real data

reCost started as a cost optimisation tool. Then we kept finding things that cost tools don't show you: broken pipelines, security gaps, and metadata bloat at a scale nobody had visualised before.

FOUNDER STORY

Built on real client data.

Founded by Ido Lazar · 2023

Founded by Ido Lazar after years of cloud data architecture work, reCost.io was built to solve a problem we kept seeing: teams were overpaying for S3 not because they didn't care, but because they couldn't see what was happening.

We started by analysing cost data , bucket totals, storage class distributions, request patterns. But as we connected more accounts and started reading S3 access logs at scale, we found things nobody else was seeing. Iceberg tables with 40,000 snapshots and no expiry policy ever configured. EOL Lambda runtimes making millions of requests per month to sensitive buckets. Go services with a 96% S3 error rate that had been running for months with no alert.

The cost problems were observability problems in disguise. We built reCost to fix both.

MISSION

Engineering teams deserve object-level visibility into their data layer

CloudWatch shows you bucket sizes. Query engines show you query results. Nobody shows you what's actually happening at the object level , which IAM roles are touching what, which tables have metadata accumulating unchecked, which pipelines went silent three weeks ago. That's what reCost is for.
