I don't think you understand the property inspection process.
They have developed a platform to streamline / digitise it.
Barrier to entry would be development of software good enough to entice customers to switch, integrations with cameras, integrations with property management platforms such as PropertyMe and PropertyTree, and there's a patent pending I believe assuming for some of their IP. Not huge barriers but not something a bloke in his Mum and Dad's basement would knock over swiftly, and there's a decent amount of $ invested to get to where they are now.
It's a slow process taking hundreds of photos, completing the inspection on paper, and sharing with landlords / tenants for sign off. Software, and HD panoramic photos can make it a lot faster and of higher quality.
