Dan Slaven, a Dallas entrepreneur, has launched RealEstateDealSheet.com, a membership-based website for commercial real estate professionals prospecting for new deals. Slaven is president and chief executive officer.

The website provides information on completed deals and listed properties to developers, architects, lenders and equity providers. Its profiles also attract brokers, owners, tenants and leasing agents.

In its first month, the site generated more than 230 connections, posted nearly 100 deals, attracted more than 160 unique visitors and suggested nearly 10,000 deals, according to Slaven. New members extended more than 1,800 invitations, he ads, and the site drew more than 500 visits in one day.

Slaven has been a partner in Dallas-based Silverado Interests, a commercial real estate investment firm, since 2008.
