Startups to Watch 2024: These companies from last year's list made headlines



As St. Louis Inno put together its annual Startups to Watch list for 2024, a key component of our selection process is determining the companies we believe will reach critical milestones in the year ahead. Given the precarious nature of startups, there’s no sure bets, but several of the companies chosen for our 2023 list proved they were worth watching last year. Here’s a look back at some of the biggest headlines from last year that were generated by companies on our 2023 Startups to Watch list.

Peptyde Bio acquired by Boston-area firm

Peptyde Bio, a St. Louis-based agriculture technology startup developing natural fungicides, was acquired in December by Cambridge, Massachusetts-based Invaio Sciences.

Peptyde was spun out of research at the Donald Danforth Plant Science Center in Creve Coeur. The acquisition marked the first startup exit for the Danforth Technology Co. (DTC), a subsidiary of the Danforth Center focused on helping Danforth Center scientists commercialize their research and technology. DTC launched in 2022, and Peptyde Bio was the first startup it established.

Another highlight for WingXpand in 2023 was being named a a winner of the U.S. Army’s xTechSearch 7 technology competition.

Inclusively raises $13M to help workers seek accommodations

St. Louis-based startup Inclusively, which makes software to help employers manage staff with workplace accommodations, raised $13 million to deploy a new technology platform it launched.

Inclusively said in November 2023 it raised $13 million in a Series A funding round led by San Francisco-based Firework Ventures. The Series A funding for Inclusively comes as it has expanded its technology, launching a new “workplace personalization product” called Retain, designed to help all employees at a company request workplace accommodations. In addition to employees with disabilities, Inclusively said Retain can help employees with accommodations in areas such as mental health, immigration, veteran status and caregiving.
