We cloned 10 years of sales, inventory, and supplier data from a retail chain into a business simulation. Then, we put frontier AI models in charge for 120 days. Most made less money than a simple greedy algorithm Introducing ShelfLife E-Sim:

Today, we're introducing idler – a frontier data research lab. We've raised a $9M seed round, led by @0xalpo and @FrankieIsLost from @paradigm, with participation from @ycombinator, @LongJourneyVC, and angels including @marrc, @catheryn_li, @dcposch, @JanineLeger, @LynettCapital, @feross, and @nur_daulet_. This funding helps us build the evals, benchmarks, and reinforcement learning environments that the world's leading frontier labs use to train and measure their models.

What is ShelfLife E-Sim (measured 2026-08-26):?

ShelfLife E-Sim measures how well AI agents run a simulated retail business day by day over a long horizon, managing inventory, purchase orders and economic outcomes.

Enterprise work mostly
“E-Sim is a long-horizon resource management benchmark built on a stateful simulator of retail operations.”

Tier C · a leaderboard, listed apart

Niche: a handful of models scored, or built by an RL vendor.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

How we got to tier C

Adoption: built by Idler. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
Confirmed: a line from its own site or paper places it.
Judged a leaderboard, arena or index rather than one benchmark (or not a benchmark at all): listed apart.

A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
