Spreadsheet Engineering Ltd is majority owned and managed by Grenville Croll.
Grenville was responsible for re-engineering the Lotus 1-2-3 spreadsheet software for the European marketplace in 1984. Whilst at Lotus he worked with Mitch Kapor, Jonathan Sachs and the software engineers who took Lotus 1-2-3 through its early versions. Subsequently, for an unbroken period of nearly fifteen years he founded and ran two SME’s (4-5-6 World and Eastern Software Publishing), which developed and marketed Lotus and Excel add-ins and related training. The products provided a variety of functions from graphics, communication interfaces, function libraries and printer drivers through to more advanced technologies including Monte Carlo Simulation, Neural Networks and Linear Programming. Grenville delivered a series of management training courses to support this software to over 1500 delegates from some of Europe’s largest companies. He most recently worked for Frontline Systems, a company founded and managed by Daniel H. Fylstra the founder of Personal Computer Software, later renamed VisiCorp, publishers of VisiCalc, the first mass market spreadsheet. For the last eight years Grenville has been closely involved with the European Spreadsheet Risks Interest Group (www.eusprig.org) of which he is now chairman.
Grenville has an Honours Degree in Computer Science, is a Chartered Engineer and a member of the British Computer Society.
