St. Louis-based Capital Innovators has backed six startups for its accelerator program’s fall 2021 cohort. Each of the startups will participate in a 12-week accelerator program. Selected companies receive $50,000 in seed funding and mentorship. The cohort includes companies from four countries. After staging its recent accelerator programs virtually due to the Covid-19 pandemic, Capital Innovators said its new cohort will include in-person programming.
