They sure have chosen their preferred client industries of Government and Financial Services wisely then. Those industries (a) are accustomed to paying that much for their technology, and (b) are very unlikely to leave your platform once you start using your wares, since the difficulty of getting them as a customer in the first place (and how slow they move and how much paperwork / due diligence is required) directly translates to difficulty for them to move off of your system.
Brilliant.
