Goodwin, a Columbus, Ohio financial technology company for private charter aviation, has acquired STACK.aero, a business operations platform used by charter brokers, aircraft operators and corporate flight departments. The deal was announced on October 20, 2026.
Financial terms were not disclosed.
STACK.aero will continue as its own product and brand within Goodwin. Founder Greg Jarrett remains chief executive and the existing team stays in place, according to the announcement. Customers do not need to migrate and are not required to adopt Goodwin's services.
What STACK.aero built
STACK.aero was founded in 2014 and is built on Salesforce. Its tools cover customer management, aircraft sourcing, quoting, contracts, trip management, invoicing and business intelligence for charter businesses. The company lists offices in Atlanta and North Sydney, Australia.
Its broker tools track trip history, client preferences and revenue, handle quoting and trip requests, and source aircraft through marketplace connections and a broker's own aircraft database. STACK.aero also integrates with Avinode, the charter marketplace, and with Adobe Acrobat Sign for contracts, Avi-Go reported.
"STACK.aero was built by aviation veterans who understood that brokers and operators needed more than generic software," Jarrett said in the announcement. "They needed technology purpose-built for the way this industry actually operates."
“Goodwin was built on a simple belief: the charter broker isn't going anywhere.”
Why Goodwin is buying
Goodwin builds software that handles the money side of charter trips. It says client funds are held in separate, client-titled bank accounts rather than mixed with a brokerage's operating funds, a safeguard it presents as a way to reduce risk in charter payments. Goodwin is not a bank; its banking services are provided by Core Bank, a member of the FDIC.
Its Dynamic Trip Ledger and Invoicing product tracks client invoices, operator bills, vendor payables and payments in one place, with wires, card payments, ACH transfers and instant payments linked to each trip's records. AI-assisted workflows flag discrepancies and automate reconciliation, according to Corporate Jet Investor.
Goodwin also gives brokers portals that show balances, funded trips, payment status and pending disbursements, and its broker software turns an operator's quote into a client proposal once the broker adds a margin, Avi-Go reported.
By adding STACK.aero, Goodwin aims to cover the whole charter process in one environment, from a client's first inquiry through booking, trip management, payment and financial reconciliation.
"Goodwin was built on a simple belief: the charter broker isn't going anywhere," said co-founder Tolga Demirel. "The relationships and trust behind this industry are irreplaceable."
What changes for customers
In the near term, little. STACK.aero customers keep using the product as before, and Goodwin's customers gain access to STACK.aero's operations platform. Goodwin's payment capabilities will be made available to STACK.aero customers over time, the companies said, without giving an integration timetable.
"Every charter trip involves financial transactions between multiple parties," said Ben Clarke, Goodwin's co-founder and co-chief executive. "Our vision is to make the movement of money as seamless as the movement of information, while reducing the risks that come with it."
A buying spree in charter software
STACK.aero is Goodwin's second acquisition in about two months. It earlier bought DineUp, a Los Angeles aviation catering platform, to bring catering orders, delivery tracking and related charges into the charter workflow, with those line items feeding Goodwin's trip ledger.
Avi-Go noted that charter brokerage usually keeps the quote, the operator's bill, the client's payment, vendor invoices and the broker's commission in separate records that are reconciled by hand after a trip. Linking all of those figures to one trip record is the main change Goodwin is offering, and the two deals suggest it is assembling a front-office CRM, trip ledger and add-on services in one place.
Because migration is optional, adoption will depend on whether brokers find the combined workflow worth switching on. Neither company disclosed revenue, customer numbers or funding history.
