The first startup I built was DropSend which did $250,000 of profit a year, which was sold after about 18 months. That's the "little file uploader" you're referring to.

The second startup I've built is our events business. We've grown that to $2m+ in revenue per year.

The third startup I've done is Think Vitamin Membership which is now at $1m in revenue after just 12 months.
