Built by an operator, for operators.
Erhart Industry Solutions LLC is the company behind Dromi and Defenestro Marketing Solutions. We build mortgage origination software the way we wish someone had built it for us: from inside a working branch, judged only by whether it funds more loans.

I am a mortgage operator turned founder. I started Erhart Industry Solutions in 2026 after real production experience on the loan side, and the platform grew out of the tools I needed every day and could not buy.
That operator's eye runs through everything we ship. Dromi moves loans the way loan officers and processors actually work, with a real pipeline from LOA to pre-processing to main. The borrower portal is built around the documents that actually get requested: the mortgage statement, driver's license, homeowners insurance, utility bill and note. TCPA compliance was built into the SMS work before a single message went out.
I am based in Gilbert, Arizona, and I build for the shops I came up in: the broker and the branch that need an edge without an enterprise budget.
In 2026 the company took on a second name. Defenestro Technologies is the trading name that everything customer-facing now sits under, and the software became Dromi. Both names were chosen on purpose, and the reasoning is written out on the names page.
What we build
Dromi
A mortgage CRM that carries a file from the first dial to the funded loan: pipeline, automations, call analytics and document processing. AI reads the documents, balances the file and automates conditions, cutting hours of data entry per loan.
What Dromi does ServicesDefenestro Marketing Solutions
Mortgage direct mail, live transfers, live data lead sales, personalized advertising and the campaign management to run them. Measured on cost per funded loan rather than response rate.
What we runWhere we are headed
One platform for the whole broker stack.
The goal is to collapse the mortgage broker's tech stack into a single platform. Lead intake, pipeline management, direct mail at scale, secure document collection and outreach all live in one place, instead of a pile of disconnected tools that never talk to each other.
It is a builder-operator playbook. Solve the workflow problems I have lived, sell the result back to the industry, and compress what used to take a separate CRM, a call and text vendor, a lead aggregator, a mail house and a pipeline management tool. I also run the mail as a service myself, so smaller shops get serious direct mail without building that capability in house.
