About Line

What do we do
Re-inventing credit for millennials and GenZ's like us by delivering it instantly on an app for a monthly subscription, payable as you get paid but without income or credit restrictions.

The problem
Growing population of GenZ and Millennials (1B) are in essential jobs with non-standard work arrangements , including over 50M in the US. They need frequent access to affordable credit to deal with frequent monthly income variance. Credit finance companies like One Main Financial are the only easily accessible option today, charging $300 for a $500 loan.

The solution
Up to 10% of your cashflow on your smart phone for $5.99/month, no interest, income or credit checks. Use it whenever and wherever you need it e.g. existing bank accounts, everyday merchants, monthly bills etc. Pay as you get paid.


  • User-base of over 50,000, growing at 100% Month on Month.
  • Commercial pilot with Western Union who has 60M customers that overlap with our users, in the works.
  • Commercial pilot with Gig-Wage, rapidly growing gig-payroll provider for SME's with over 50,000 users.
