  • The MACH37 accelerator announces it’s Spring cohort: Start-up accelerators take in young companies, and give them some money ($20K-$150K) and guidance in exchange for some equity (around 8%). Often they take in sets of companies, called a cohort, at the same time so they can schedule various talks and other activities over a perhaps 3 month period. This culminates in a “demo day” where additional investors see what the companies have accomplished and possibly invest additional money in them. Well known tech start-up accelerators are Y-Combinator and Tech Stars, but they have a more general tech focus. MACH37 is based out of the DC area and is focused on cyber security companies. It has funded 5 companies for it’s Spring cohort.
