The systems
We don't sell services.We install systems.
A service is effort you rent monthly. A system is infrastructure that stays installed — documented, automated, and measured. East Star builds 4, on one shared intelligence layer.
The architecture
4 systems. 1 layer. 0 silos.
Each system can run alone. None of them is designed to. Every signal — velocity, spend, conversion, margin — routes through one intelligence layer, so a stock position can pause a campaign and a margin change can reprice a SKU without a meeting in between.
That routing is the product. The systems below are the 4 places it becomes a decision.

The 4 systems
4 places a signal becomes a decision.
Demand & Inventory OS
96.1%Days-of-cover accuracy — trailing 90dDecides reorder points, PO timing, and stock allocation before the stockout, not after it.

−1.2 ptsTACOS vs target — trailing 90dDecides bids and budgets against contribution margin, with stock position as a hard gate.

+18%CVR delta — median test winner, 2025Decides what to test, in what order, from ranked hypotheses — never redesign-by-opinion.

Connected is a claim. Here are the signals.
6 of the 23 signals the layer routes daily. Each one replaces a meeting.
| From | Signal | To | Decision it gates |
|---|---|---|---|
| 01 Demand | Days of cover ≤ 28 | 02 Advertising | Campaign budgets throttle before a stockout burns rank. |
| 02 Advertising | Ad-attributed velocity | 01 Demand | Forecast separates paid demand from organic before reordering. |
| 04 Profit | Margin per SKU | 02 Advertising | Bid ceilings are set by contribution, not ACOS. |
| 03 Listing | CVR by placement | 02 Advertising | Traffic is only bought for pages proven to convert it. |
| 04 Profit | Aging inventory cost | 01 Demand | Markdown logic triggers before storage fees exceed margin. |
| 01 Demand | Restock ETA | 03 Listing | Test queue pauses on SKUs about to go dark. |

Automation with judgment
The machine executes. Humans decide.
- Data ingestion 14.2K RECORDS/DAY
- Forecast refresh DAILY, PER SKU
- Bid changes within approved rules 12 RULES LIVE
- Reorder-point math 96 SKUS
- Anomaly alerts ≤15 MIN LATENCY
Every pipeline has a named human owner and an override path.
Overrides logged · coverage reported like a KPI- Rule and threshold changes
- Pricing strategy and repositioning
- New-product forecasts — no history, no autopilot
- Supplier and cash trade-offs
- Every override, and what it taught the system
Automation coverage across 2025 engagements: 71%, trailing 90 days. The remaining 29% is judgment — by design.
Installation
Installed in phases. Measured at every gate.
Systems install through the 4-phase engagement model — audit, design, build, operate. Metrics are agreed before price. The audit report is yours to keep either way.
See the engagement model- Audit — 14 days · read-only access
- Metrics stated before price — always
- Forecast vs actual — published monthly
Start with the system your P&L is asking for.
The audit identifies which of the 4 systems moves your margin first — with the model to prove it.
