About the company
Currently we are hiring for a VC backed startup a fast growing fintech startup based in Bangalore.
It is a super app to digitize Indiaās 50M+ sales agents where they can get access to relevant products & services, receive training through interactive videos on āhow to sell, what to sell and whom to sellā, and earn money. For businesses, we help them save a huge effort in managing and training these agents and help them increase their reach to every nook and corner of the country.
India is a trust deficit market which cannot be accessed through Internet Marketing on Facebook and Google as the majority of the customers need training, push, motivation and a primer on why and how to use a product.
To solve this problem, traditional industries like BFSI, Telecom, Automobile, Real Estate etc. use 50M+ frontline sales executives to drive distribution. We believe that not just for these traditional industries but also for emerging companies in FinTech, EdTech etc these agents will play a pivotal role in accessing trust deficit customers.
They have grown to a Ā 100,000+ agent network across India (growing 50% MoM) & are funded by tier1 VCās and angels in India.
