A house worth $588,000 looks like a substantial cushion. Then the owner needs cash. The mortgage still has $350,000 outstanding; the money is in the walls, economically speaking, and the walls are unhelpful at the checkout. Button Finance uses those figures in its own explanation of home equity lending. Its proposition starts with this awkward distinction: owning wealth and being able to spend it are different things.
- Borrow against home equity while keeping an existing first mortgage.
- Choose a fixed-rate loan or a variable-rate line of credit.
- Digital underwriting speeds the process; credit, property and paperwork still decide the outcome.
Ten months to the first loan
In a public 2020 LinkedIn post, founder Jason Harris announced Button’s first home equity loan. The company was about ten months old. He described two achievements that rarely receive equal billing in a startup story: building a pricing engine and getting licensed to originate mortgages. The software could calculate an offer. The licenses made the offer a business.
Harris had worked in fintech investment banking at Jefferies, traded mortgage-backed securities at Amherst Pierpont, and held an operations role at PeerIQ. That background matters. Mortgage lending involves assessing households, valuing property and managing a file through a sequence of decisions. A handsome application form handles only the entrance.
Button raised a $2 million seed round in October 2021, with Hildene-advised entities, L&L Capital Partners and angel investors participating. In May 2025, Hildene Capital Management led a $5 million Series A. Button said it had grown to more than 60 employees and nearly tripled monthly volume in six months. Those are company-reported measures, without an accompanying absolute loan-volume figure.

The mortgage you do not replace
The customer problem becomes sharper when an existing mortgage has an attractive rate. A cash-out refinance replaces that mortgage with a larger one. A second-lien home equity loan can leave it in place. Button lends against the same property, behind the first mortgage, giving the homeowner another payment rather than rewriting the original loan.
The distinction is useful for renovations, debt consolidation and other large expenses. It also explains why Button’s advertised 85% limit needs careful reading. That percentage covers the combined debt secured by the property, including the existing mortgage. It is not an invitation to borrow another 85% on top.
The fixed-rate HELOAN supplies a lump sum, repaid over a chosen term. Button’s August 2026 Gold guidelines list 10, 15, 20 and 30 years. Its HELOC is a different instrument: a variable-rate line indexed to Prime. Crucially, the published initial draw must be at least $50,000 or 75% of the line, whichever is greater. A line of credit here comes with substantial borrowing at the start.
A five-day promise, measured in paperwork
Button describes proprietary AI underwriting designed to serve qualified borrowers overlooked by conventional lenders. Its website advertises funding in as few as five days, while also promoting funds within two weeks. Both are speed claims; neither turns a conditional application into a guaranteed closing date.
The partner resources page provides a more instructive view. Disclosures, setup, initial approval and final conditions have separate turnaround targets. A file awaiting missing information enters suspense. The daily submission cutoff is 5:30 p.m. Eastern; arrive after it and the queue starts the next day. Even digital lending has office hours.

Separate turnaround targets apply at each stage. Missing items and closing requirements affect the total.
There is a practical lesson for other businesses in those deadlines. Publish the handoffs, name the documents and distinguish an initial decision from a finished transaction. Customers can prepare for a process they understand. “Fast” becomes more useful when someone explains what must happen first.
The price of getting to yes
Button promises no hidden fees. That is a transparency claim, rather than a claim that borrowing costs nothing. Its published appraisal schedule lists a base full-appraisal fee of $550 in California and $745 in Washington, with specified surcharges and exceptions. The closing bill depends on the property and transaction.
Time can carry a price too. The October 2025 lock policy generally locks a validly priced submission for 30 days. An extension of 15 days adds 0.125 percentage points to the rate; 30 days adds 0.250. The policy also lets correspondent partners absorb certain extension costs through their purchase premium. This is lending economics, complete with intermediaries and deadlines.
Eligibility narrows the invitation further. The August 2026 Gold guidelines vary permitted leverage by credit score and occupancy, and exclude certain properties and first-mortgage structures. HELOCs are unavailable in Texas under those rules. And the home secures the debt: replacing unsecured balances with mortgage borrowing changes the consequences of failing to repay. A smaller monthly payment alone does not establish a better deal.
The second customer is a broker
Button also serves mortgage brokers and correspondent lenders. Its partner toolkit includes a pricing portal, checklists, disclosure instructions and marketing materials. The business therefore has two audiences: the household needing funds and the professional trying to get that household’s file closed.
The team biographies make that arrangement less mysterious. Alongside technology and AI architect Ashish Dole are experienced underwriters, account executives and closers. India mortgage operations are represented too. The staffing suggests that automation works alongside mortgage expertise, with people still handling the complicated parts of a secured loan.
Spring EQ and conventional banks offer competing ways to tap home equity. Button’s pitch combines digital underwriting, underserved-borrower access and partner distribution. Its appeal is clearest when a homeowner has usable equity, a first mortgage worth retaining and a repayment plan that survives the extra debt. The house supplies the collateral. The household still has to supply the payments.
