Forecast and replenish, or plan the whole business.
Singuli is an AI demand-forecasting and replenishment tool for retail and DTC — it sizes buys and cuts stockouts. Tightly does the forecast and replenishment too, and adds the top-down merchandise financial plan, open-to-buy and assortment that turn a forecast into a season plan the whole team runs.
Keep what works. Lose what breaks.
From forecast to full plan
Singuli forecasts and replenishes. Tightly adds the merchandise financial plan and open-to-buy that turn a forecast into a season plan — the buy, the budget and the range, not just the reorder.
One number across teams
Forecast, plan and buy reconciled on one figure, so finance, merchandising and supply chain work off the same numbers instead of three.
The full merchant toolkit
Assortment, markdown and price elasticity live in the same plan, not as separate exercises around a forecast.
It shows up in the numbers.
