 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
 
 
 <ul>
 <li>
 High barriers to entry - minimum account balances, brick-and-mortar onboarding, and low financial literacy
 </li>
 <li>
 Irrelevant experiences - platforms designed for traders and financial experts, alienating the majority
 </li>
 <li>
 Fragmented offerings - investment products scattered across multiple platforms
 </li>
 <li>
 Limited information accessibility - lack of organized, accessible information for retail investors
 
 
 </li>
 </ul>
 Our impact has been swift and significant:
 
 
 <ul>
 <li>
 3 million app downloads
 </li>
 <li>
 $8.8 billion in annualized traded value
 </li>
 <li>
 #1 platform in terms of traded value (30% of market orders &amp; 11% of retail traded value)
 </li>
 <li>
 84% of our users are investing for the first time
 </li>
 <li>
 65% of our users come from outside capital cities, previously underserved by financial institutions
 
 
 </li>
 </ul>
 
 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&rsquo;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&rsquo;re still in the early stages of our story, but we know for a fact that we won&rsquo;t stop until everyone in MENA has equal opportunity to make informed investment decisions and grow their wealth.
 
 
 
 At Thndr, we&rsquo;re looking for people invigorated by our mission, not just those who simply check off all the boxes. We&rsquo;re looking for people that are hungry to become agents of change and that understand the huge responsibility associated with dealing with people&rsquo;s money.
