In an ideal world, we'd love to give Otto away for free but we live in a world that lives on the exchange of currency. We have expenses, development costs and well, our lives. We're also a bootstrapped business, that means we don't take VC money to make an app like most young startups do. We like to say we're customer funded, this drives us to make a better product that you will pay for and find useful. And we want to keep this sustainable for as long as we can.
