MonitorBase vs TrustEngine

The overlap is real but it stops early

Both products bill against the borrower retention budget. Both fire alerts when a past customer shows intent. The similarity ends there. MonitorBase sells the signal itself. TrustEngine sells the signal plus the conversation that follows. A lender running both pays twice for the same alert layer. The alert layer sits in marketing spend. The comparison layer sits in sales enablement spend.

What MonitorBase watches

MonitorBase describes itself as a borrower retention system that mines opportunities from a contact database. The site groups alerts into four families. Predictive scenario alerts cover home buyer, home seller, cash-out refinance, rate and term and MI removal. Second home and reverse mortgage alerts sit in the same family. Inquiry alerts include mortgage inquiry, new homebuyer inquiry and an EPO warning. Credit migration alerts track score, bankruptcy, payment history and unscorable movement. Listing alerts flag property for sale and property for rent. Experian is named as the data partner of more than fifteen years.

What TrustEngine does once the alert fires

TrustEngine descends from two separate companies. MortgageCoach dates to 1997 and builds side by side loan comparisons for borrowers. Sales Boomerang launched in 2017 and built the alert engine. The current site puts MortgageCoach at the centre. The stated aim is that borrowers choose on strategy rather than on rate alone. That is a pull-through and contact rate argument. It is not a database mining argument. The integration list runs wide. It names MGIC, Arch MI and National MI for mortgage insurance quotes. It also names Homebot, HomeBinder, Lodestar and ClosingCorp. TrustEngine added AI conversation summaries in April 2026. An Encompass integration with ICE Mortgage Technology followed in May 2026.

Ownership moved on both sides

Mobility Market Intelligence acquired MonitorBase on 13 February 2025. Terms were not disclosed. MMI had already bought the CRM platform Bonzo on 2 August 2023. MMI now sells data, monitoring and CRM as one bundle. TrustEngine sits in the LLR Partners portfolio. LLR took controlling stakes in both predecessor companies in early 2022. The rebrand was announced on 15 February 2023. Bob Jennings was named chief executive in January 2026. MMI shipped MonitorBase alert upgrades for pre-mover and equity signals during 2025.

The integration lists point at different stacks

MonitorBase names Total Expert, Surefire, Insellerate, BNTouch, Usherpa, Big Purple Dot and Bonzo for CRM. For origination it names Calyx, Byte, LendingPad and Take3. Encompass is absent from that list. Salesforce and HubSpot are reached through Zapier. TrustEngine names Encompass directly and SimpleNexus for point of sale. It also names Optimal Blue, Polly and Lender Price for pricing data. Encompass shops should read that difference closely.

Neither publishes a price

MonitorBase says pricing is customised for every mortgage professional and routes buyers to sales. TrustEngine has no public pricing page. Ask MonitorBase for cost per monitored record per month and any minimum database size. Ask TrustEngine whether billing runs per seat or per funded loan. Ask both for a twelve month total at your real contact count. Ask each vendor for a written definition of a billable alert.

What the review sites leave out

The Capterra listing for Sales Boomerang shows no rating and no user reviews. Its price field reads contact vendor for pricing. MonitorBase carries a Capterra listing under the name Database Marketing Alerts. The rating there could not be confirmed. Neither vendor publishes recapture rate by cohort. Neither publishes cost per funded loan. Claims on both sites are vendor stated and unverified.

Which one to pick

A lender with a big past client database should look at MonitorBase. That fit is strongest where the CRM is already Total Expert, Bonzo or Insellerate. The job is trigger volume into an existing call queue. A lender losing deals during rate shopping should look at TrustEngine. The job is winning borrowers who are already in conversation. Ask MonitorBase how monthly alert volume is capped and what happens to unworked alerts. Ask TrustEngine what share of customers buy MortgageCoach without the alert module.
