Rocket Companies, the parent of major lender Rocket Mortgage and nascent brokerage Rocket Homes, acquired personal finance app Truebill in December for $1.275 billion. As Rocket Companies continue to build out a full suite of home services businesses, acquisitions like this one indicate the resources and scope the company can bring to bear on the effort. The company can use an app like Truebill across a vast array of its services, thus leveraging scale, introducing new services and spreading cost across several businesses.
