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.

// Context

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.

// Challenge

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.

What we did

Six steps from methodology
to a working product.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.
