DiscoverOrg, a Vancouver company that provides marketing data to businesses, has purchased a large rival in Maryland.

The cash deal for RainKing is worth more than $100 million, DiscoverOrg told The Columbian newspaper on Monday.

The privately held companies both provide businesses with lists of potential sales targets, augmented by direct phone numbers, leadership information and details of prospects' business strategies.

DiscoverOrg has grown into one of downtown Vancouver's largest businesses; it employs 350 altogether. RainKing had 200 employees; DiscoverOrg declined to say how many of those it will retain.

DiscoverOrg reported revenue of just over $71 million last year. RainKing was roughly half as large, claiming revenue of $33.9 million for the annual Inc. 5000 ranking of large private companies.

Last year, DiscoverOrg said it had raised between $1 million and $10 million from a group of investors. It had previously taken a large investment from private equity firm TA Associates.

Correction: This article has been corrected to note that RainKing's headquarters are in Maryland, not Massachusetts.
