Tally, a financial technology startup based in San Francisco, is debuting a service that it claims is “the only free automated savings service” for consumers. The 4-year-old startup, known for automating people’s credit card debt payments, is expanding beyond its initial product, which debuted last year, into one that automatically transfers a pre-set amount of money from consumers’ checking accounts into a savings account each week. Tally will not pay customers interest on the new accounts, which are held by FDIC-insured bank partners, says Jason Brown, Tally’s cofounder and CEO.
