J.J. Allaire's other brother and partner in ColdFusion was Jeremy. Jeremy has started two successful companies since leaving Macromedia. They are BrightCove and Circle. I don't know about Circle but at one time parts of BrightCove were running on ColdFusion.
But years later when J.J. started a second company, it was only a few weeks old when Gates swept in and bought it for millions of dollars.. Shut it down and moved everyone to Seattle.. He immediately assigned J.J. and his team to build a new project called Azure.
