Your ads and inventory, finally connected.
Most brands advertise products they're about to sell out of. Or push dead inventory no one wants. Lenny knows what's selling, what's sitting, and what's running low—so your ad dollars go to products you can actually fulfill.
- Stop advertising low-stock items before you oversell
- See which products are low-stock so you can adjust campaigns
- Get alerts when bestsellers need reordering
- Liquidate dead inventory with targeted campaigns
A decade of results. Built for what's next.
