A day after Airbnb Inc. sued a Miami developer claiming a breach of their partnership agreements, the developer responded by accusing the home-sharing giant of abusing its power and taking trade secrets to grow its own business.

NGD Homesharing LLC, led by Harvey Hernandez, and San Francisco-based Airbnb teamed up in a much-hyped venture promising more urban residences. The developments include Natiivo Miami and the 324-unit Niido Powered by Airbnb in Kissimmee, part of the bigger Natiivo and Niido brands.
