Malachi Charbonneau

The operator who grew into the company he now runs

Malachi Charbonneau spends his days on a problem most people never think about: the money hospitals earn but never collect. Charges that get missed. Codes that get entered wrong. Patients assigned to the wrong clinician on the wrong shift. As general manager and chief executive of medaptus, a Boston software company owned by Volaris Group, his job is to turn that quiet leakage into something hospitals can see, measure, and fix.

medaptus is not a household name, and Charbonneau does not seem interested in making it one. The company builds software that automates charge capture and reconciliation, optimizes how hospitalist teams distribute patients, and feeds analytics back to the people running hospital medicine departments. It is unglamorous, back-office work. It is also the kind of infrastructure that, when it fails, costs a health system real revenue and burns out the staff left to sort out the mess.

What makes Charbonneau unusual as a chief executive is how he got the job. He did not arrive as an outside hire with a turnaround mandate. He joined medaptus in 2011 and stayed, moving through the company one function at a time until there was little about it he had not touched.

Learning the business from the floor up

He started in client implementation. For a company that sells to hospitals, implementation is where theory meets reality: the software has to fit the way a specific health system actually bills, staffs, and documents care. Charbonneau spent those years on the ground with more than 65 provider organizations, getting a close look at their revenue cycles and hospitalist programs. It was, in effect, a paid education in how American hospitals run their operations - and where they lose money.

From implementation he moved to customer care, then into project management, then to running sales and marketing. Along the way he served as vice president of customer success and sales. By the time he took overall responsibility for the business, he had seen it from nearly every angle: the customer's frustrations, the salesperson's pitch, the implementer's headaches, the executive's spreadsheet.

During his years leading implementation, medaptus collected multiple annual KLAS awards, an industry marker of customer-service quality in healthcare IT. That period seems to have shaped his instincts. The through-line in how he talks about the company is not technology for its own sake, but technology that reduces friction for the people using it.

Before medaptus

Charbonneau's path into healthcare software started at MEDITECH, one of the large electronic health record and enterprise software providers, where he worked in professional services and customer support. He holds a bachelor's degree in Management Information Systems from Bridgewater State University in Massachusetts - a practical, systems-oriented foundation that maps neatly onto a career spent making software behave inside complicated institutions.

The MEDITECH grounding matters. Charge capture and patient assignment do not happen in a vacuum; they live on top of the EHR. Understanding how those big clinical systems work, and how support teams keep them running, gave Charbonneau a head start on the integration problems that define medaptus's product.

The Volaris era

In November 2020, medaptus was acquired by Volaris Group, part of Constellation Software, the Canadian acquirer known for buying and holding vertical-market software businesses for the long term. The company's founder, Laurence Hagerty, stepped into an advisory role. A few months later, in May 2021, Charbonneau was named general manager.

The transition said something about how medaptus saw itself. Rather than parachuting in a stranger, it handed the business to the person who already understood it best. Under Volaris ownership, the mandate is less about chasing hypergrowth and more about steady, durable performance - a fit for an operator who thinks in terms of customer retention and product reliability rather than splashy launches.

What he is building now

Under Charbonneau, medaptus has kept expanding its two core product lines. Charge Pro, the charge-processing engine, drew a partnership with Banner Health, one of the larger nonprofit health systems in the United States, to push charge automation further toward precision rather than just speed. On the operations side, the company's Assign product helps hospitalist teams balance patient loads, and a newer Hospital Medicine Analytics platform gives department leaders faster visibility into how their operations are running.

That last product captures his current preoccupation. The pressures he names - volatile patient volumes, thin staffing, overloaded caregivers - are structural, not temporary. His bet is that hospitals do not just need faster software; they need software that surfaces the right information at the right moment so leaders can plan, allocate people, and stop revenue from slipping away unnoticed.

The style of the man

Charbonneau presents as an operator's operator: pragmatic, customer-first, more comfortable talking about workflows and reconciliation than about vision statements. He still stays close to sales operations, a habit from his earlier roles that keeps him in contact with what customers are actually asking for. There is a consistency to his public comments over the years - the same emphasis on making clinicians' jobs easier, on visibility, on reducing the administrative drag that wears hospital staff down.

It is a career that argues for a slightly unfashionable idea. In an industry that loves the story of the outsider who blows everything up, Charbonneau is the counterexample: someone who learned one company deeply, stayed, and earned the right to lead it. For the hospitals that depend on medaptus to keep their charges clean and their patient lists balanced, that continuity is probably the point.
