After a long career as a real estate principle for over 20 years & juggling over 100+ staff and working 7 days a week ( you know how it goes) ... I developed a real estate software of my own.Not by myself of course. I'm about as technical as a cardboard box! What I actually did was employ two brilliant programmers and chained them to their desks, surrounded by the team, in my actual real estate office.Together, the programmers & I designed, developed and refined a real estate software program around the actual needs of the office.In other words, we developed a software program specifically to solve our own day-to-day work problems. And we kept at it until the entire team found it easy to use and helpful. Until it made our days easier and more productive.Of course, then my friends and colleagues in other real estate agencies - even competitors - noticed something was up. Word got out we had a 'secret weapon', and they all wanted in.So... I started a software company....I had the ideal program already fully developed. So I wasn't putting the cart before the horse, as most software companies do. I wasn't trying to develop a program that sold well, but didn't work that great. I wasn't madly tacking on features at the last minute. I wasn't under-testing everything. We were not rushing the launch to meet the sales team's over-ambitious promises. (That's how most software companies work.)The program was there. Already proven. Already marketable.So we went to market.And the rest is history.
