Lenders, admins and support people who answer the phone.

Matthew VanFossen, CMB
A producing loan officer turned founder. Matt started MAT because he wanted Saturday-afternoon access to a loan file from his phone — and because lenders, not vendors, should decide how origination works. He drives product direction and the cooperative’s growth, and writes and speaks regularly on mortgage technology for National Mortgage News and Chrisman Commentary.

Jerry Melia
Career mortgage executive. Jerry leads MAT’s cooperative model — member lenders fund the roadmap together, vote on priorities, and share everything that gets built.

Joseph Rodriguez
Joe runs operations and implementations — onboarding new member lenders onto BIG POS and keeping every integration, from Encompass to the partner network, running day to day.

Kelly Hund
Kelly leads national sales for BIG POS, BIG AI and Big Agent — the first conversation most lenders have with MAT, from discovery through pricing and the Client Advisory Board introduction.

Dan Alvare
Dan leads the engineering team that builds BIG POS, BIG AI and Big Agent on Encompass — the weekly release train, the Partner Connect integrations and the mobile apps.

Brent Elmer
Brent works with lenders evaluating BIG POS, BIG AI and Big Agent — from first demo through contract and go-live.

James Bentley
Jim leads the product-support team that member lenders talk to every day — configuration help, training and escalations.

Tom Tratta
Tom supports BIG POS admins and loan officers — workflows, rules, documents and the mobile app.
