Betterment
Betterment is a robo-advisor and financial planning platform offering automated investment management, tax-loss harvesting, retirement planning, and goal-based portfolio rebalancing. Founded in 2010, Betterment serves individual investors through its Digital and Premium Advisory plans, and employers through Betterment at Work — a 401(k) plan administration product that integrates with 350+ payroll providers via a private partner API. Betterment does not offer a public developer API; third-party application developers access Betterment account data through open banking aggregators such as Plaid and BankSync. Betterment Engineering maintains an active open-source presence on GitHub, publishing internal tools for background job processing, split testing, Flutter golden testing, and Rails security.
