The problem PaySe solves

Almost 90 percent of small businesses in India still have no links with formal financial institutions.
Primary reasons are :

For borrowers -
The current lending process is quite tedious for a small business owner with intensive manual under-writing.
This leads to higher turnaround times to even get to an answer whether the customer is eligible or not.
Unbanked users find it very difficult to apply for loan since there is no check for creditworthiness.

For lenders -
Banks continue to lose customers to bigger competitors banks, newer banks & now fin-tech companies.
Unable to get accurate creditworthiness of unbanked users because of lack of data
