Frequently Asked Questions

What is Antigravity Investments?

Antigravity Investments is an online investing company based in San Francisco and registered with the Securities and Exchange Commission as a registered investment advisor (RIA). Our technology and social impact potential has been recognized by American Express, the former head of, the social entrepreneurship organization Ashoka, and leading entrepreneurs and venture capitalists.

We help people and organizations invest with lower fees and higher returns by combining the latest investing research and techniques with automated systems that radically reduce the cost of providing investment advice. For example, academic research has indicated checking investment allocations daily for opportunities to increase diversification can increase returns by around 0.5% annually.

Betterment, Wealthfront, and other "robo-advisors" are good at providing financial advice, but not good at providing investment management advice and services. In fact, many robo-advisors outsource their investment services to external advisors, such as Betterment's use of BlackRock income portfolios.

Antigravity Investments specializes in developing technology to optimize investment performance. We offer an online advising tool and personal advising for large accounts, but our main focus is on improving investment performance, rather than advising.

Antigravity Investments connects to our clients' investment accounts (brokerage accounts), at major brokerage firms. We are starting with Interactive Brokers and will soon support Fidelity, E*Trade, Vanguard, Ally Invest, DriveWealth, and TradeStation, with more brokers on the way. Users can create an account on the Antigravity Investments website, and after linking a brokerage account, they can use our advisor service or investing marketplace to choose an investing portfolio to invest with.

Yes to all of the above! We support over 170 countries via our partner brokerage firm Interactive Brokers—the full list of supported countries is available here. We also support organizations; simply open a regular user account to get started, no special setup needed. Investment advisors: please get in touch to explore our services which include automated asset management for your clients and a white label robo-advising service.

Each strategy at Antigravity Investments has a different annual management fee. All management fees are visible before you choose to invest with a strategy. We bill users when our system connects to and places trades in a user's brokerage account. Our billing formula is (length of time since last rebalance) * (annual management fee adjusted for the length of time since last rebalancing). We support different billing methods, including credit card and bank account billing.
