ComputerTalk Never Got Bought, Its Founder Conducts Mahler

For nearly 40 years the Markham software company has built its ice Contact Center entirely in-house, turned down every acquisition offer, and outlasted rivals like Cisco, Five9 and Genesys. Its founder, Mandle Cheung, runs it while personally funding a 100-piece orchestra so he can conduct Mahler.

Most software founders spend their fifties rehearsing an exit. They line up the bankers, groom the metrics, and wait for a strategic buyer or a private equity fund to make the call. Mandle Cheung spent his rehearsing Mahler. He founded ComputerTalk in Markham, Ontario in 1987, and almost four decades later he still owns all of it. No merger. No acquisition. No board pushing for a sale. Just a contact center company that kept its head down and kept shipping while the industry around it changed hands over and over.

The product is called ice Contact Center. If you have ever called a bank, a hospital or a government line and been routed, queued, surveyed and called back, you have used software that does what ice does. It is the plumbing behind customer service: the routing engine that decides which agent gets your call, the interactive voice menus, the chat and email and SMS threads, the analytics that tell a manager why the queue is 12 minutes deep on a Tuesday. It is not glamorous. It is deeply necessary, and ComputerTalk has been refining the same core product for a very long time.

The contrarian move is staying

The contact center market has been one of the most heavily traded corners of enterprise software. Genesys has changed ownership. Five9 has been through a rollercoaster of public-market drama and a nearly-completed sale. Cisco bought its way into the category and folded it into Webex. A newer wave - Aircall, Nextiva, UJET - raised large venture rounds on the promise of a modern rebuild. In that context, the single most unusual thing about ComputerTalk is not a feature. It is a decision, repeated year after year: don’t sell.

Making a living takes work. Building a business was a huge challenge. Mandle Cheung, founder and CEO

That independence shows up in the details. ComputerTalk says it has never acquired another company, never merged, and never outsourced product development. The softphone agents use, icePhone, is built in-house rather than licensed from a third party. Roughly 96% of the staff live in Canada, most of them in Markham, and customer data sits in Canadian data centers under Canadian privacy rules - PHIPA, FIPPA and PIPEDA, the acronyms that matter when your customers are hospitals and public agencies. For a company selling to BC Children’s Hospital Foundation, London Health Sciences Centre and the Western Canada Lottery Corporation, “the data stays here” is not a slogan. It is a procurement checkbox they can actually tick.

A 20-year bet on Microsoft

If you want to understand how a small Canadian company held its ground against giants, look at what it did with Microsoft. ComputerTalk did not wait for the platform to mature. In the early 2000s its engineers were already inside Microsoft’s unified communications roadmap. When Live Communications Server shipped, they reportedly reverse-engineered its protocol with Wireshark to add instant messaging to ice before an official path existed. When Office Communications Server arrived, they routed live voice calls through it. When Microsoft moved the goalposts to Lync, then Skype for Business, then Teams, ComputerTalk moved with each one.

2005
Live Communications Server. Early instant-messaging integration for ice, built by reading the protocol off the wire.
2007
Office Communications Server. Live voice calls routed from OCS into ice Contact Center.
2010
Lync + UCMA. The telephony core is rebuilt on Microsoft’s managed API as Lync launches.
2012
Partner of the Year. Named Microsoft Communications Partner of the Year; ice 7.0 ships Lync-native.
2015
Skype for Business. Early certification for ice 8.0 on Skype for Business 2015.
2024
Teams-native. iceBar for Teams ships; UC Award for Best Microsoft Teams Contact Center Solution.
2025
Teams Phone extensibility. Early adopter; pursuing Microsoft’s Teams Contact Center Unify Certification.

This is the quiet advantage of not being for sale. A company that is constantly being re-org’d, integrated into a parent, or prepped for the next buyer has a hard time committing to a 20-year platform relationship. ComputerTalk has had the same north star the whole way through: be the contact center that lives inside whatever Microsoft ships next. That continuity is worth more than it looks. Enterprises buying contact center software are not buying a demo - they are buying a decade of upgrades, and they can see which vendors have actually survived one.

The man with the baton

Here is where the story stops being a business story. Cheung grew up in Hong Kong, in a family with no musical background. At 13 he heard a Saint-Saëns violin concerto on the radio and, in his words, was hooked on music ever since. He went to the University of Manitoba to study computer science, and while he was there he took a few music courses and tried conducting for the first time. Then he spent roughly the next 50 years building a company instead.

He never let the other thing go. Around age 67 he did something almost no amateur ever gets to do: he assembled a full orchestra of 100 professional musicians, the Mandle Philharmonic, and paid for it himself so that he could stand on the podium and conduct. In November 2018 he led Mahler’s Symphony No. 4 for a room of paying guests. In 2019 came Mahler’s First. In 2020, Brahms and Beethoven. Each concert runs him something like $300,000. He conducts; the professionals play; the music is real.

I need something for my brain. I go crazy if I just lie on a beach. Mandle Cheung, on retirement

It is easy to read the orchestra as a rich man’s hobby. Look closer and it rhymes with how he built the company. A conductor does not play a single note. The job is to hold a hundred independent parts in your head, set the tempo, and trust the people in front of you to execute. Cheung says as much about ComputerTalk - he credits his team for executing the strategic calls he makes. The same person who spent 38 years refusing to hand his company to someone else is perfectly happy to hand the actual playing to specialists. He wants the baton, not the violin.

What you can actually do with it

Strip away the founder’s biography and there is a working product underneath. ice Contact Center is an omnichannel cloud contact center: voice, email, web chat, SMS and social all land in one queue, routed by the same engine. For an organization already standing on Microsoft Teams, ice slots in natively, so an agent answers a customer without leaving the app they already live in. On top of that sits the newer layer the whole industry is racing toward - AI-assisted routing, agent-assist suggestions, automated notifications through iceAlert, and analytics that turn call logs into something a manager can act on.

The practical pitch is narrow and honest. If you run customer service on Microsoft Teams, and you care about where your data lives, and you want a vendor that will still be independent in five years to take your support call, ComputerTalk is an unusually clean fit. It will not out-market Genesys or out-raise a venture-backed newcomer. It competes on a different axis: it is still here, still the same company, still answering the phone.
