Swift is building a next generation checkout stack for India - a platform rolling up payments and logistics solution for all fulfillment needs. We give businesses the opportunity to provide a customer experience at par with the likes of Amazon and Flipkart, all the while saving money and time.
Its basically Amazon without the website listing - we let our sellers design their own sales channel :-)
We believe there are many things a seller or small business has to worry about when selling online, logistics/payments/etc shouldn't be one of them. With our solution, SMBs and D2C brands get access to technologies and services like next day delivery, same day delivery, live package tracking, Card/Cash on delivery, scheduled delivery etc, making parcel delivery just as simple as collecting payment.
We also provide robust APIs which makes it easy for developers to add shipping capabilities to their multichannel online store.
We want to be the #1 checkout platform that’s reliable, easy to use and affordable.
