I've heard https://www.ally.com/invest/ will but don't know for sure. At .01 per share I'm not really interested in finding out. Ally Invest requires a minimum opening purchase of $100 per order in OTCBB and Pink Sheet stocks, and adds 1¢ per share on the entire order for stocks priced less than $2. Ally Invest doesn’t accept opening trades for stocks below 1¢ per share.
