WHO ARE WE? Thndr was founded on a bold dream to democratize access to investing through smart tech and human-centric design.

This is simply our way of saying we give anyone with a smartphone the simple and easy access they need to preserve and grow their wealth. At the same time, we’re shaping the future of investing while actively driving the economies we serve by promoting local investment products. 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people had access to it due to: - High barriers to entry — In the form of excessive minimum account balances, complex, outdated onboarding, and low financial literacy.

- Irrelevant experience — Catered toward expert traders and financial specialists, therefore alienating the majority of the population. - Fragmented offering — Investment products were not gathered in a single, intuitive outlet. We don't just talk about change, we deliver it. Here's a glimpse into our impact so far: - 5.5 million app downloads - EGP 1B+ average daily traded value across 2025 - #1 digital investing platform in Egypt for the third consecutive year - 76% of users are first-time investors - 40% of our users come from outside of capital cities and have previously had limited access to financial institutions Building on the success of our core platform, we are continuing to change culture and break down barriers by launching Rumble, the subscription-based investment recommendations platform.

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. Going beyond traditional investment advice, it offers long and short-term investment recommendations and financial content through engaging articles and videos that guide users on their financial journey and maximize their returns. At Thndr, we're looking for people driven by our mission to help us democratize investing across the MENA region.
