I looked at their website and looked for how they aim to help startups. I thought they had a mobile application that you can download for you to create your own. But that's not the case. They are a development company that will help you build your own mobile and web applications for your startup. So instead of you creating your own web or mobile application, they will help you with developing your own using their experience to speed up and catapult your development.
I just wasn't able to immediately see the info on how you'll be able to pay for their services given that you yourself need to get funded first. Perhaps if your startup successfully gets funded, they have a share in it?
