I am stalking Lob :) I respect what those folks are doing and may be a client/reseller soon. IMO the pricing now reflects what the end user is willing to pay but when it gets lower it will allow my company to integrate their services and resell them for a small profit (to fund the work). I'm looking for signs from Lob that they are going to be like Twilio, fanatically supporting users... constantly lowering the price and being dead simple/easy to use. They seem on the right track but trust is the most important part of API sales, again IMO.
