About

Named results include Heatable (48% of inbound aftercare resolved without a support ticket), Phoenix Financial Consultants (100% of a 700+ advisor network monitored monthly), and Stiltz (7.86x targeting lift validated on live direct-mail campaigns). Founders Nick Harding and Mark Somers both have prior track records building fintech and credit-risk consultancy businesses.
