Description
About ShipDelight :

Our Journey, Our Vision From Ground Operations to a Scalable Post-Purchase Engine.

When we started ShipDelight 10 years ago, it was about building a digital bridge between supply and demand redefining post-purchase intelligence in e-commerce logistics.

We always believed that India already has the infrastructure to connect the last mile, it simply needed a strong technology layer to transform it into a reliable and scalable delivery network.

Over the years, weve evolved from a problem-solving logistics team into a full-stack, tech-first platform that powers post-purchase excellence blending automation, business intelligence, and customer experience.

We have stayed close to the ground by building platforms across B2C, B2B logistics, partnering with fashion brands, D2C challengers, traditional retailers, and now government-backed ecosystems like ONDC.

At ShipDelight, our intention is to carve out a niche by aligning with our clients long-term vision: Empowering brands to drive retention and revenue by owning their post-purchase experience.

We believe in offering more than just a service, we provide affirmation, built on the belief that if you Own your data, you own your customer.

Our Purpose With over two decades of domain expertise and a combined experience of 55 years, the founders of ShipDelight possess unparalleled insight into the challenges that arise from incomplete integration between e-commerce and logistics.

This profound understanding enables us to develop comprehensive solutions that address the root issues, ensuring seamless operations and optimal performance for our clients.

Our Mission is to lead a logistics revolution powered by smart technology for modern Bharat.
