About 8FIGURES
8FIGURES develops an AI-powered personal financial advisor addressing wealth management fragmentation across brokerage accounts, retirement funds, real estate, crypto, and private equity.

Pre-Series A with approximately 8 team members including three co-founders (CEO, CPO, CTO). Has received Forbes coverage and serves thousands of users.
The Role
