NextStep, a Seattle startup which uses its technology platform to retrain displaced workers for roles in the healthcare industry, has raised $2.5 million in new funding. The company, founded in 2018 and spun out of Seattle’s Pioneer Square Labs, integrates app-based and in-person skills practice to train people to become certified nursing assistants (CNAs), which it calls the largest healthcare role in the United States. NextStep is growing in Colorado, a pilot state for the startup, where it already trains and places new CNAs at more than 70 facilities run by its employer partners.
