Hengam
Hengam means “the moment”.
One test decides what we build: it has to measurably raise a store’s revenue or lower its costs, and keep doing so as commerce changes.
Hengam · all four apps: 6,158 reviews on the Shopify App Store, one dot each. Drawing: the Hengam mark as a solid band, turned towards the light, one dot for each review of the four apps.
