Chicago startup Anthill is helping companies better engage and train their blue-collar workforce, and it just raised a seed round of funding to grow its technology.

Anthill announced Thursday that it raised $3 million in a round led by Rethink Education. Other backers include BBG Ventures, The Fund, JFF and Chicago’s Origin Ventures, which led a $1.24 million round in Anthill back in February.

Anthill focuses on what it calls the “deskless” workforce, i.e. employees in the manufacturing, supply chain, retail and other sectors who aren’t tied to a desk all day. The startup helps companies promote and train this workforce, with the goal of retaining their best employees.

Founded in 2020 by Muriel Clauson and Young Jae Kim, Anthill creates “talent mapping” software that gives companies data about their employees, including their skills, interests, career development goals and more. Companies use the data to help fill open roles in the business, know when to re-skill and train workers, and generally better understand their workforce. Anthill’s tech can help companies spot employees who are best positioned to be trained up for new roles, and help identify workers that can benefit from additional development.

The startup, which participated in the 2020 Techstars New York accelerator program and was one of Chicago Inno’s 21 startups to watch in 2021, has worked with companies like Verizon and ConAir.
