I am the creator of the Problemio business apps which are some of the top mobile apps for planning and starting a business with 1,000,000+ downloads across iOS, Android and Kindle.
I am also an author of three business books (marketing to reach 1,000,000 people, on starting a business, and on the mobile app business).
I am also a business coach. On my apps and in my private coaching practice I have helped over 1,000 entrepreneurs. That means I can probably help you quite a bit as well.
My areas of expertise are mobile apps, software engineering, marketing (SEO and social), and entrepreneurship.
