Company profile
researched Aug 2026Mostt (Mostt Inc.) operates a mobile investment application designed for parents saving and investing on behalf of their children. The product allows families to set up recurring monthly or twice-monthly contributions, collect monetary gifts from friends and relatives for birthdays and other occasions, and round up everyday purchases to add small amounts to a child's investment portfolio. A money-growth calculator on the company's website projects hypothetical portfolio outcomes based on an initial deposit, contribution amount and frequency, and the child's age, using an assumed average annual investment return (illustrated at 7% on the calculator page and stated as 8% with an age of majority of 25 in the site's disclosures).
Mostt Inc. describes itself as an investment advisor in California registered with the U.S. Securities and Exchange Commission, with a written disclosure brochure (Form ADV) filed with the SEC. Brokerage services for Mostt clients are provided by Alpaca Securities LLC, a FINRA- and SEC-registered broker-dealer and SIPC member, with SIPC protection of up to $500,000 per customer including $250,000 for cash. The company states it transacts business only in states where it is registered or exempt, and does not provide tax advice. The website advertises bank-level security and encryption, and lists additional features as forthcoming, including financial rewards and bonuses from brand partners when customers shop.
