Audit-ready operations, a help desk that consistently exceeded expectations, and an internal team freed for strategic work

Jackson Square Aviation (JSA) is a global leader in commercial aircraft leasing. From its San Francisco headquarters and offices in Dublin, Ireland and Singapore, the company manages a young, high-value fleet—roughly 334 aircraft worth approximately $13 billion—leased to about 63 customers across 32 countries. With an average aircraft age of around five years, JSA pairs competitive financing with customized fleet solutions for airlines worldwide. 

What began as a ten-person, private-equity-owned business changed dramatically in 2013, when JSA was acquired by Mitsubishi MUFG—one of the largest banks in the world. Overnight, a lean startup inherited the compliance expectations, audit cadence, and security mandates of a global financial institution. As the business expanded internationally, technology stopped being a back-office support function and became the operating backbone of the company. 

The Challenge:

A Lean Startup Gains Complex Mandates for Compliance, Security, and 24/7 Support

In the early days, JSA’s entire IT department was just two people: Senior Vice President Jonathan Santos and Manager of Information Systems John Doioka, both hired as generalists. As the company grew across three continents, they hired a third IT generalist, yet the demands on that small team continued to increase. JSA needed to provide 24/7 IT support for a complex, highly technical infrastructure spanning very different time zones—while keeping headcount deliberately lean. 

The Mitsubishi acquisition raised the stakes. JSA fell under J-SOX compliance—similar to Sarbanes-Oxley—and faced regulators, auditors, insurers, and security mandates that were unfamiliar to a former startup. As Santos put it, a global parent doesn’t ask whether you’re compliant; it expects it. 

At the same time, scaling exposed the limits of “good enough” infrastructure: 

  • Latency and friction. As users in Dublin began accessing systems hosted elsewhere, “good enough” became a source of friction between departments—slowing the ability to close the books and coordinate globally. 
  • Technical debt. A migration off a legacy ERP left two systems running in parallel, doubling licensing and management costs—the kind of technical debt that compounds as an organization grows. 
  • Concentrated knowledge. When critical know-how lived only in one person’s head, that wasn’t a security model—it was, in Santos’s words, a “vacation-risk nightmare.” 
  • Expanding cyber risk. More locations, identities, vendors, and domains meant more complexity—and complexity creates the gaps and single points of failure that attackers look for.

“We don’t need to be smarter than the attackers. They just need to find the one place where our process got creative.”

—Jonathan Santos | Senior Vice President & Head of IT

The Hunt for a Solution

JSA didn’t want to build a large internal department, and adding specialized hires would only have increased cost, churn, and management overhead. The leaner, smarter path was IT staff augmentation—partnering with a managed services provider (MSP) that could extend the team’s capability rather than replace it. JSA wanted a single, trusted partner spanning everything from the security landscape to day-to-day help desk and even website design.

“We were looking for an MSP partner with whom we could build a close, collaborative relationship. That mattered to us because we run a small IT team.”

—John Doioka, Manager of Information Systems

Crucially, the trust was already there. JSA’s network operations were originally handled by ClearPoint, which was acquired by AccountabilIT, which in turn became part of Corsica Technologies. By the time the relationship carried the Corsica name, JSA already had years of established, high-level trust with the team—removing the single biggest risk in choosing an outsourced IT services partner.

The Solution:

Co-Managed IT, 24/7 Support, and Audit-Readiness

JSA engaged Corsica Technologies under a co-managed IT model—one integrated, accountable partner working hand in hand with JSA’s internal leaders. Rather than taking over, Corsica filled the gaps and scaled the team’s reach across San Francisco, Dublin, and Singapore. 

The engagement brought together several Corsica capabilities under one roof: 

JSA's IT challenges
  • A 24/7 global help desk. Corsica’s help desk team absorbed day-to-day end-user support across all three regions—the kind of always-on, follow-the-sun coverage that a small IT team could never sustain alone. 
  • Help desk outsourcing that augments the internal team rather than replacing them. The model extended JSA’s capability while keeping ownership, direction, and accountability firmly with JSA leadership. 
  • Security and risk support. As complexity grew with global expansion, Corsica helped JSA close the gaps that single points of failure exploit—supporting a business-continuity program that now runs hand in hand with IT processes. 
  • A repeatable audit-readiness routine. The Corsica team helped build a custom queue dedicated to audit evidence, with clear ownership, documentation, and cadence—so audits became a steady routine rather than a fire drill. 
Jonathan Santos - SVP IT, JSA

“An MSP extends the capability of the business and augments the team. What it can’t do is own the ownership—so you set clear boundaries, expectations, and cadences. Expectations matter more than contracts.”

—Jonathan Santos | Senior Vice President & Head of IT

For a regulated, financial-services-owned organization, that clarity is everything. Corsica’s breadth—spanning managed IT, managed cybersecurity, and the kind of vCISO-level guidance that translates technical risk into board-ready business language—meant JSA could lean on one partner instead of stitching together point solutions. As Santos notes, leadership doesn’t want dashboards; it wants clarity, fewer metrics, and better narratives. 

Results:

24/7 Support. Internal IT Augmented. Seamless Compliance Processes.

The partnership delivered exactly what a scaling, audit-bound business needs: predictability and peace of mind. 

The help desk became a standout. “What surprised me most,” Doioka said, “was that the help desk team consistently exceeded our expectations”—a result validated by positive feedback from JSA’s own users. With reliable 24/7 IT support in place, JSA’s internal team was freed from day-to-day firefighting.

“Our IT team can now confidently shift focus away from day-to-day help desk responsibilities and dedicate more time to higher-level, strategic initiatives.”

—John Doioka | Manager, Information Systems

Audits became uneventful—the highest compliment in a regulated business. With a documented evidence queue, clear task ownership, and a steady cadence, JSA walks into internal and external audits ready, with the metrics to prove it. “Silence is golden,” as Santos puts it.

“Success in an audit is making it business as usual. We built a custom queue for audit evidence, so when the auditors arrive, we’re ready—and we have the metrics to prove it.”

—Jonathan Santos, Senior Vice President & Head of IT

Just as important, the model eliminated the “vacation-risk nightmare.” By offloading help desk operations and documenting processes with a trusted partner, JSA no longer depends on any single person’s knowledge to keep the business running. The broader business benefits most of all—with dependable global support enabling the company to scale with fewer surprises.

“What gives me peace of mind is that our users are fully satisfied with their IT needs and the level of support we provide them.”

—John Doioka, Manager, Information Systems

Lessons for Leaders Scaling IT Internationally

JSA’s journey offers a practical playbook for CIOs and senior operators guiding their organizations through international growth. The throughline: scaling globally isn’t really about technology at all. It’s about process, ownership, and partnership.  

  • Design for scale with boring, well-owned systems. Point solutions are fast but don’t scale; repeatable operating models do. 
  • Delegate execution, never accountability. A trusted MSP augments the team—but direction, risk appetite, and ownership must stay with leadership. 
  • Treat compliance as a daily routine, not an event. Documentation and an established cadence help make audits a regular part of operations rather than panic-inducing scenarios. 
  • Translate risk into business language. The job isn’t to teach the board cybersecurity—it’s to explain risk like any other business decision. 

“When you scale internationally, you’re not really scaling technology—you’re scaling judgment, discipline, and clarity. Growth isn’t about shiny new IT systems; it’s about fewer surprises.”

—Jonathan Santos, Senior Vice President & Head of IT

After more than a decade of expansion, the relationship endures for one simple reason—one that defines the kind of partner Corsica aims to be.

“Trust can’t be dictated; it has to be earned. We’re fortunate to have Corsica as a trusted partner.”
