That model is underwritten largely by pharma companies, which pay — as the deck explains — because they "have the most to gain immediately." Pharma companies can't make revenue if patients can't afford their prescriptions.
The way that Sempre works across different healthcare players makes it an attractive investment, says Ray Ko, a partner at Social Capital, which led Sempre's 2016 seed round and participated in its series A last summer, and Sempre board member.
"We looked at a ton of drug delivery companies like the PillPacks of the world. And those are interesting, but didn't really align all the folks that exist in this system" as Sempre does, Ko told Business Insider.
This also makes it easier for Sempre to add new partners, whether they are health insurers or pharma companies, Ko says. He uses the metaphor of a mall, where having many different stores will attract a mix of different types of customers.
"Every new drug they add to the system will attract the next payer," and vice versa, he said. Facebook and Slack are very different products but something they share with Sempre is that "every participant that gets added to the system incentivizes other participants to join and participate."
