SellerOS, the same thing,
written in code.
Twenty-five years rebuilding operations by hand, at Lamoda, PEC, Brinex. SellerOS is the same methodology compiled into a Decision Engine: the algorithm optimizes for gross profit, not CTR. Take rate on gross profit, not GMV, if ads ate the margin, our cut is zero.

On marketplaces, sellers pay for turnover, not profit. Ads, commissions, returns, fines, every point of GMV eats into margin. Agencies and SaaS vendors take a cut of revenue, they win when you grow, even if you're losing money doing it.
In parallel, the seller faces hundreds of decisions a day: ad bid, the floor price for a promo, re-shelving an SKU, restocking a supplier. All of them taken by hand, on instinct, with a lag.
Write a system that takes decisions every 15 minutes, anchored on a single metric, maximum gross profit. Encode the same operator-grade approach we ran at Lamoda and PEC, with one twist: now it's an algorithm, not a person.

Six steps from methodology
to a working product.
-
01 / Discovery
Twenty-five years of operator decisions, distilled into an algorithm
Walked with marketplace founders through 40+ operating cases: which signals they weigh, how they price risk, what separates «cheap to hold the SKU» from «cheap to move it». Captured 146 rules and 18 ADRs, architectural decisions.
-
02 / Decision Engine
Target function, maximize gross_profit, not GMV
Unlike classic MMP tools, we don't optimize ROAS and we don't chase rank in search. The objective is gross profit on a trailing 30 days, adjusted for holding cost per SKU and return risk.
-
03 / Data layer
Four data contours, no black boxes
We pull three marketplace APIs + your ERP/1C. Clean, normalize, align by SKU and warehouse. Every number in the dashboard is clickable down to the source row.
-
04 / Profit-share economics
We earn only on your profit
Take rate is applied to positive gross_profit only. No profit for the period, commission = 0. Ads ate the margin, our invoice is empty. Sellers see, for the first time, a SaaS that loses money when they do.
-
05 / Closed beta
Five sellers, five categories, 90 days
5 different categories, fashion, household, beauty, sport, kids. Volume from 40M to 1.4B ₽/year. 90 days of live observation on real margin versus a control period.
-
06 / Pre-seed 2026
Now, pre-seed round and first paying customers
Opening access for sellers from 100M ₽ GMV/year. In parallel, a pre-seed round to scale the team and infrastructure for 200+ customers by end of 2026.
What the beta showed over 90 days.
We don't optimize CTR. We optimize the money that stays with the seller at the end of the month.Zafarkhon Alikhodjaev IDEAL Consult · author of «Tasty Stories»
