About Freetrade Freetrade’s mission is to become the default place to invest. Investing has been too complicated and expensive for too long, keeping millions from making the most of their savings. We’re changing that. We’re building our team and looking for people who are excited to reshape how our customers invest and grow their wealth. If you’re driven by solving complex problems and building innovative products, you’ll fit right in. 2026 is a big year for us.

We’ll continue to operate as an independent business while gaining access to the resources and support of an established leader in the space. This year, we’re accelerating our roadmap and taking our products to the next level. We’re building new features like mutual funds, bonds, and family investment tools.
