About Titan Titan is an award-winning wealth manager with a mission to increase our generation’s compound growth rate. We plan to do this by putting a human wealth advisor in every pocket.

We harness frontier technologies like artificial intelligence to build a platform that gives advisors superpowers, enabling them to serve clients they historically never could. Backed by a16z, General Catalyst, Sam Altman, and many others, we manage over $1 billion in assets for clients across the country. Why Join Titan For the right person, we believe Titan will be one of the most rewarding jobs they ever have. Ambitious Vision: When we put private wealth management in every pocket, we’ll make a legacy-defining impact in growing our generation’s wealth to new heights. Critical Why Now: The advent of LLMs unlocks our vision to democratize personalized wealth management for everyone. This drives our urgency every day.

Compensation: Titan offers competitive cash compensation and well-above-market equity packages because we want every team member to be an owner.
