Select Software Tools Inc, the client-server modeling software house, appears to be on a mission to stealthily buy up competitive products and migrate the users over to its own products. Following its acquisition earlier this year of the Systems Engineer product line from Learmonth & Burchett Management Systems Plc (CI No 3,077), the company has now gone to Intersolv Inc for its Excelerator II analysis and design product line. Select, which will take on full support and maintenance for the product, has its eye on the 8,000 or so customers who still use the Exclerator tools, and says it is devoting a team to work with Intersolv staff to provide a smooth transition over to its own Select Component Factory. It plans to provide a bridge linking the two product lines, something that should be ready by the fourth quarter of this year. Terms of the deal were not disclosed, with Select saying only that it would pay Intersolv certain royalties over the next two years. Anything is welcome for Rockville, Maryland-based Intersolv at the moment, as it still smarts from the $21.2m loss it reported in its last financial year. Intersolv has a surprisingly low-profile for a company which bills itself as among the top 30 software companies in the world, with 900 employees and $160m revenues. It was formed in 1991 as a result of the merger between Sage Software Inc and Index Software Inc, from which Excelerator come. Intersolv now says it will concentrate on its three strongest markets: PVCS for software configuration management, DataDirect for standards-based data connectivity, and Factory2000 for year 2000 systems renewal.
