**Description: Sheet 1 contains our matched data from matching our SDC pull with our cohort companies list found in '''Accelerator_Cohort_Companies'''. Sheet 2 removes the duplicates from the previous match. Sheet 3 contains the list of VCCompanies, which accelerator they went through, the date of their first investment. Sheet 4 contains our cohort list matched with the crunchbase organizations, but it contains too many duplicates to use.
