Cleaning startup Cleanify has raised $1.8 million in seed funding. That might not seem like much money when compared to the $50 million round that Handy just raised, or the nearly $40 million that Homejoy raised before shutting down. However, the Cleanify model is a bit different. Instead of offering its own on-demand cleaning services, Cleanify aggregates the listings of existing cleaners. When we wrote about the startup in January, we described it as Expedia for the cleaning industry — consumers get to browse ratings and compare prices, while cleaners get to reach new customers and also use new tools for managing their relationship with existing clients.
