Who Are We? 

Thndr was founded with the dream to democratize access to investing through smart tech and human design, which is just a fancy way of saying giving anyone with a smartphone easy access to preserve and grow their wealth. At the same time, we’re promoting local investment products to propel the economies that we serve

History has shown that investing is the single greatest way to build long term wealth - but before Thndr, only a very small percentage of people had access to investing due to:
  • High barriers to entry - In the form of minimum account balances, brick and mortar onboarding and low financial literacy.
  • Irrelevant experience - Catered towards traders and financial experts, therefore alienating the majority of the population.
  • Fragmented offering - Investment products are not gathered in a single outlet.
On our short journey we’ve validated that there is a need for our solution, as illustrated by these key figures:
  • 3 million app downloads
  • $8.8bn in annualized traded value
  • #1 platform in terms of traded value 
  • 84% of our users are investing for the first time
  • 65% of our users come from outside of capital cities and have previously had limited access to financial institutions
We’re proud of how far we’ve come and the size of our impact in just a few years - but we’re just getting started and are excited for what’s to come.
It’ll take a lot of passion, bold risks, and hard work to fulfill our mission of democratizing investing in MENA and giving everyone an equal opportunity to generate and grow their wealth.
