This is potentially a huge step for RF. 7-11 corporation has 56,000 outlets world-wide. Compare to Starbucks with 24,000.
Very likely this initial trial is an initiative of 7-11's SoCal regional management, but if it succeeds and Soylent is picked up by the parent company, the potential upside would expand Soylent's market many times over.
One result, a year or so on might find online sales only a tiny part of their cash flow, and powder an even tinier part.
Another outcome, assuming the trial is a success and a partnership with 7-11 is cemented, is that when the Bar is re-introduced, it might be a retail-only product, at least at first.
