Supply chain & demand planning intelligence

Find out what your demand plan is really costing you — in one week.

Letta turns your sell-in, sell-out, inventory and forecast data into a clear diagnosis: where the forecast fails, where cash is trapped in stock, and what to fix first. Built by planners who've run demand and S&OP at enterprise scale.

The leak

If any of these sound familiar, your plan is losing money.

01
Forecast accuracy nobody actually measures by SKU or channel.
02
Planners override the forecast on gut feel — and no one checks if it helps.
03
Stock piling up in the wrong places while others run short.
04
S&OP meetings that review the past and decide nothing.
05
Monthly reporting that eats days in Excel.
06
Data spread across files that never reconcile.

Why Letta

Enterprise planning discipline, sized for the mid-market.

Letta is built by a supply-chain leader with 15+ years running demand planning and S&OP at global enterprise scale — sell-in/sell-out, inventory, channel allocation, and weekly S&OP across large multinational operations. That discipline, applied to companies that have outgrown spreadsheets but don't need a six-figure suite.

We build tools, not just slides

You leave with working dashboards and models, not a PDF that gathers dust.

Fixed, fast, productised

Clear scope and price. No open-ended consulting meter running.

Vendor-neutral

We sharpen the tools and process you already have — no software to sell you.
