... Sven here (sharing this acccount with Alex). I'm full-time on YogaTrail. Besides me there are 2 full-time employees (Drupal Developers) on board, plus we use lots of free development resources from BUZZWOO!, a digital agency I co-founded. I consider this a huge advantage compared with other bootstraped start-ups and it enabled us to actually produce lots of software. Other than the main website YogaTrail has a very successful facebook app (we use for content marketing), several mobile apps and a bunch of very cool tools we use for marketing and growth hacking.
