Who Are We?

Thndr was founded with a powerful vision: to democratize investing in the Middle East and North Africa by putting financial power in the pockets of everyday people. Through smart technology and human-centered design, we're giving anyone with a smartphone easy access to preserve and grow their wealth while promoting local investment opportunities that propel our regional economies.

Before Thndr, only a very small percentage of people had access to investing due to

  • High barriers to entry - minimum account balances, brick-and-mortar onboarding, and low financial literacy

  • Irrelevant experiences - platforms designed for traders and financial experts, alienating the majority

  • Fragmented offerings - investment products scattered across multiple platforms

  • Limited information accessibility - lack of organized, accessible information for retail investors

Our impact has been swift and significant:

  • 3 million app downloads

  • $8.8 billion in annualized traded value

  • #1 platform in terms of traded value (30% of market orders & 11% of retail traded value)

  • 84% of our users are investing for the first time

  • 65% of our users come from outside capital cities, previously underserved by financial institutions

Rumble was born with the vision to empower everyday individuals to build wealth confidently and intelligently through access to timely and in-depth advice from the industry’s top experts.

Building on our success with Thndr, we are continuing to change culture and break down barriers by launching Rumble, the first-of-its-kind subscription-based investment recommendations platform.

You can consider Rumble your new financial advisor. Going beyond traditional investment advice, offering long- and short-term investment recommendations and financial content through engaging articles and videos that can guide users on their financial journey and maximize their returns.

We’re still in the early stages of our story, but we know for a fact that we won’t stop until everyone in MENA has equal opportunity to make informed investment decisions and grow their wealth.

At Thndr, we’re looking for people invigorated by our mission, not just those who simply check off all the boxes. We’re looking for people that are hungry to become agents of change and that understand the huge responsibility associated with dealing with people’s money.
