I am a developer, several years back, a couple friends and I wrote a loyalty app/saas. The site, allowed a restaurant/shop/bar owner setup a couple types of deals ie "Buy X get Y Free" among others. Each restaurant had a QR code, and when someone would purchase something, the customer would scan it and get a "punch". The owners could track everything via the web. Due to all of us having a 9-5, and this being our first project, we failed, because we didn't realize beforehand that you had to hit the streets every day, and we didn't have the capital to quit our jobs when we figured that out. The only way, to really sell a product like this, was cold calling. Adwords, facebook, etc etc, does not work when trying to reach a small business owner/manager. They are too busy working, to go out randomly searching for stuff. Needless to say, we learned a ton about selling. So, I developed Sales Invaders!. A "sales staff as a service". Things are pretty simple right now, as I'd like to figure out if there is a market for this. If anyone has any specific questions, feel free to ask!
