The Software That Runs the Companies That Run Your IT

There is a whole layer of the economy that stays out of view on purpose. When the dentist's office, the accounting firm down the street, or your kid's school has a computer that stops working, someone shows up - or logs in remotely - and fixes it. That someone usually works for a managed service provider, an MSP, one of the tens of thousands of small IT companies that quietly keep small business running. And a large share of those MSPs run their entire operation on software made by a Tampa company called ConnectWise.

You have almost certainly never used ConnectWise. That is the point. ConnectWise is the vendor behind the vendor - it sells to the people who serve everyone else. It does not have a consumer app or a household name, and it likes it that way. What it has instead is a grip on the plumbing of a channel that moves hundreds of billions of dollars a year.

01 / What it doesFive tools an IT shop cannot run without

Strip away the acronyms and ConnectWise sells the back office of an IT business. There is a system for tickets, projects, and billing - professional services automation, or PSA, which longtime users still call by its old name, Manage. There is remote monitoring and management, RMM, which watches thousands of client machines and patches them automatically; older shops know it as Automate, and before that LabTech. There is ScreenConnect, the remote-access tool that lets a technician take over your screen from across the country, which ConnectWise bought in 2015. And there is a growing security and backup line - managed detection and response, a security operations center, and cloud backup - that lets a small IT shop resell enterprise-grade protection.

02 / Who buys itOne customer, studied for forty years

ConnectWise has exactly one type of customer: the MSP. That focus is unusual. Most software companies chase several markets at once; ConnectWise picked a single audience in the early 1980s - before “MSP” was even a word - and has been studying it ever since. Its partners range from two-person shops to firms with hundreds of technicians, and collectively they support millions of small and mid-sized businesses.

That single-mindedness shows up in the culture too. CEO Manny Rivelo, who took over in 2024 after running the cybersecurity firm Forcepoint, describes the company in two words: “MSP-obsessed.” It is a slogan, but a revealing one - there is no second audience to hedge toward.

03 / The problem it solvesHow a twelve-person shop acts like thirty

Small IT shops are perpetually understaffed and buried in alerts. A single MSP might manage a few thousand endpoints, each throwing off warnings, patches, and requests. Without software, that is chaos; with it, one technician can supervise what used to take a team. The pitch is not glamour - it is leverage. Automation turns a small headcount into a bigger apparent one, and that math is why the tooling is worth paying for month after month.

This is also where ConnectWise's AI story lands. Rather than promising to replace technicians - a hard sell to companies that cannot hire enough of them - the company is aiming AI at the drudge work: triaging an alert, drafting a ticket, summarizing a client's history. An AI that turns noise into a billed, routed ticket does not shrink the team. It lets the team punch above its weight.

04 / The competitionA crowded map, one layer up

ConnectWise is not alone. Its biggest rival is Kaseya, which owns Datto and Autotask and competes across the whole stack. Newer, cloud-native players - NinjaOne, Atera, Syncro, SuperOps - have won fans among smaller shops who find the incumbents heavy. N-able and Acronis push on RMM and data protection. What distinguishes ConnectWise is breadth plus incumbency: it has been the system of record for a generation of MSPs, and its integrations marketplace lets partners bolt on hundreds of third-party tools.

05 / The businessSubscriptions, cross-sell, and a community

The model is recurring software revenue, priced per technician, per endpoint, or per module. The growth engine is cross-sell: land a partner on PSA or RMM, then add security, backup, and platform services over time. Layered on top is IT Nation, the partner community ConnectWise built long before “community-led growth” became a phrase. Its flagship event, IT Nation Connect, drew more than 4,000 people to Orlando in 2025 - part conference, part user group, part sales engine.

06 / The arcFrom a Tampa startup to a Thoma Bravo asset

ConnectWise was founded in 1982 by brothers David and Arnie Bellini together with Linda Brotherton, selling business software long before the managed-services model existed. It grew for 37 years as a founder-owned company, then in 2019 sold to the private-equity firm Thoma Bravo in a deal reported at about $1.5 billion - making it, by local accounts, the Tampa Bay area's first technology unicorn. Under Thoma Bravo, the company consolidated a sprawling product line, leaned hard into cybersecurity, and began the long project of unifying everything under Asio.

07 / Where it fitsThe plumbing has a name

Go one layer up the stack from the businesses you interact with and the competition thins out fast. Small businesses hire MSPs; MSPs run on ConnectWise. It is a B2B2B position - the supplier to the suppliers - and it is a durable place to sit. The open question, the one that will define the next few years, is whether ConnectWise can turn a decade of acquisitions into one coherent platform. Asio is the bet. Whether it pays off is the whole ballgame.
