Basically, a year and a half ago we decided to focus more on software we could charge for (vs. ad/sponsorhsip supported). At the top of our list was a storytelling app called A Story Before Bed (www.astorybeforebed.com) which we shipped this past November. But Jenny (our co-founder) was getting married last August so we paused our development on our primary product and spent some time developing Thrilled for You - a video guestbook for Jenny's wedding reception.
Things have calmed down a little since we shipped A Story Before Bed, and we realized we still have the app we wrote for Jenny. With wedding season coming in a few months we did some more testing, tweaked the UI, came up with a bunch of themes, and put together the website for Thrilled for You (www.thrilledforyou.com) and offered it for sale as of yesterday. :)
There are so many things we love about having our own startup... the ability to do things like this is definitely one of them. We feel the software we make is so personal when it comes out of a need we had ourselves.
Talk about a nice pivot - Wedding software is a great niche. Once your software is in the reception, it could do lots of other cool stuff. Guest lists, aggregation of iPhone / photo content from guests and speech programs come to mind.
It could even live-blog the content it gets into a timeline online during the reception. You could have a stack of 100 cards with a key on them next to the PC, accessing the online site requires a card as the login for privacy. Purchasing 100 more cards is a $10 transaction online and covers the timeline service.
