My Knack application is Verify.is and serves the P&C Insurance industry. We have just begun quoting implementations to our prospect clients. Typically, there record imports would be greater than 500,000 and adding 500,000 per year. Verify.is integrates "field services" for clients by assigning tickets to field teams of claims adjusters. Other features offered by HERE mapping would be very useful and help secure prospect clients with >500,000 records... routing and other features. If Knack does not see a need for their customers I'd also being interested in receiving a quote from Knack to integrate other features as a stand alone use-case for my clients.
