I don't think I've ever experienced customer service on this level
After using this brokerage for a few weeks now I have to say I am really impressed. I have nothing but good things to say. The customer service, the app dev team and everyone else is doing amazing work. Highly recommended to try them out.

Best customer support/communication of any brokerage I've dealt with
Aside from the truly AT communication and support, the UI has consistently improved from the time I began using the service, and is approaching a RobinHood-level of understandability and ease of use while not feeling like it's incentivizing overtrading/'action' like RobinHood does. I'm excited to see what improvements continue rolling out.

Great support, beautiful UI, exciting future
I have been with Fennel for over two months now and I can say they are one of the best brokerages. If you're willing to pay the monthly subscription, it is worth it. They have a unique vibrant UI. A lot of other brokerages feel old school, but Fennel feels new. They provide amazing customer support and they care about improving their product greatly. This is only the start for Fennel!

A story inspired by Prometheus and the spark he shared with humanity.
Fennel's name comes from the myth of Prometheus, who carried fire to humankind inside a hollow fennel stalk. That symbol, knowledge once reserved for the powerful becoming accessible to everyone, is at the heart of what we're building.
Our illustrated mini-comic walks you through the origin of our name and how this story shapes Fennel's mission today.
Knowledge is power
