IT’S AN ISA: Lumni, a company that issues income share agreements (ISAs) to college students, has acquired two companies, Base Capital and Paytronage, both of which also provide ISAs to college students. Instead of having a student pay tuition upfront or take out loans, the financing model instead takes out a percentage of a student’s paycheck after they graduate and land a job. Financial details about the transactions were not disclosed for both deals. Lumni has offices in the United States, Colombia, Chile and Peru.
