Developing B2B Cloud Applications since 2004.
In an industry that treats a funding round like a birth announcement, Quality Unit has spent twenty-two years doing something quietly unusual: building software, selling it, and keeping the whole thing. No Series A. No board deck. No exit rush. The company that started life in Bratislava in 2004 as a single affiliate-tracking script now runs three products used by roughly 150 million people - and it has never taken a cent of outside money.
The pitch on its homepage is almost defiantly plain. "Developing B2B Cloud Applications since 2004," it reads, next to a cartoon island the company calls, without irony, "the Island of B2B Software." It is not the language of a company trying to go viral. It is the language of a company that has already figured out what it is.
Quality Unit is a business-to-business software maker with a portfolio that reads like a tour through the unglamorous plumbing of running a company online. Its flagship is LiveAgent, a help desk and live-chat platform that folds email, chat, phone calls, social messages and a knowledge base into a single inbox. Then there is Post Affiliate Pro, the affiliate-tracking tool that started it all, used to run partner and referral programs. And since 2024, FlowHunt, a no-code builder for stitching together AI agents and automations by dragging boxes rather than writing code.
Look closely and a pattern emerges. Each product sits at a point where a business has to talk to people at scale - customers who need help, affiliates who need paying, and now conversations a company would rather hand to an AI agent. Quality Unit keeps finding the same kind of problem in a new decade's clothing.
The portfolio also has a fourth, quieter member. In 2021 the company folded in Nicereply, a tool for measuring customer satisfaction through short CSAT, NPS and CES surveys. It rarely gets top billing, but it rounds out the support stack: LiveAgent handles the conversation, Nicereply grades how it went. Taken together, the lineup is less a scattershot of ideas than a slowly assembled toolkit for the two things every online business eventually has to do well - keep customers happy and pay the people who bring in more of them.
The company counts around 30,000 paying customers, and they are not all tiny. Post Affiliate Pro alone advertises more than 27,000 companies on its books. The logos that show up in Quality Unit's own materials range from the very large - Huawei, Orange, DigiCert - to the specific, like the payments firm TrustPay and Virginia Tech. The end users those customers reach add up to an estimated 150 million people, most of whom will never know the software's name.
This is the quiet economics of B2B tooling. A single LiveAgent license might sit behind a support desk fielding thousands of tickets a week. Multiply that across 30,000 accounts and you get reach that dwarfs the size of the company producing it. Quality Unit employs somewhere around 47 people. The leverage is the point.
The customer mix matters as much as the count. A tool that only serves hobby websites tends to churn hard; a tool that only serves giants lives and dies by a handful of contracts. Quality Unit's spread runs the whole way, from a solo founder tracking a few affiliates to enterprise support teams routing tickets in several languages. That breadth is a kind of insurance - no single customer, and no single segment, can sink the ship.
Customer support is a mess for most growing businesses. Messages arrive by email, then chat, then a Facebook comment, then a phone call, and each channel lives in its own tab. LiveAgent's answer is consolidation: one place where an agent sees the whole conversation regardless of where it started. Affiliate marketing has its own headache - tracking who referred whom, across cookies and clicks and payouts - and Post Affiliate Pro exists to make that accountable rather than approximate.
FlowHunt is the newest problem statement. As businesses rush to bolt AI onto their operations, most hit the same wall: the interesting stuff needs engineers. FlowHunt's bet is that a marketing manager or a support lead should be able to assemble an AI agent - or a whole team of them - by connecting modular blocks, each one a task, an integration, or a model. It supports major language and image models and plugs into a growing set of tools and MCP servers.
LiveAgent competes in a crowded ring with Zendesk, Freshdesk, Intercom and Help Scout. Post Affiliate Pro goes up against Everflow, Tapfiliate and Impact. On paper, none of these are companies you would bet against a bootstrapped shop from Slovakia. And yet the difference is structural, not cosmetic: because no investor is waiting on a return, Quality Unit sets its own prices, its own pace, and its own priorities.
That shows up in concrete ways. LiveAgent has long leaned on price and channel breadth against pricier incumbents - it was rated a number-one customer service solution for small and mid-size businesses by G2Crowd back in 2017. And when the company wanted to add customer-satisfaction surveys to its lineup in 2021, it did not raise a round to fund the deal. It bought Nicereply with its own cash.
The model is refreshingly legible. Quality Unit sells software subscriptions, monthly or annual, tiered from small business up to enterprise. FlowHunt, for instance, opens at nine euros a month and climbs to fifteen hundred euros for enterprise. Every product is funded by the people using it, which is another way of saying the company's only investors are its customers.
The results are steady rather than explosive. LiveAgent's reported revenue reached roughly $20 million in 2023, up sharply from a few million just a few years earlier, and the wider company is estimated to run somewhere in the $18-20 million range annually. Modest by unicorn standards. Durable by almost any other.
Quality Unit was started by Viktor Zeman and Andrej Harsani, and the notable thing is that both are still running it two decades later. Zeman sits as chief executive, Harsani on the technical side - the same two names on the letterhead that were there when Post Affiliate Pro grew out of a client project back in 2003. Continuity like that is rare enough in software that it counts as a strategy on its own.
It also explains the company's instinct for markets other people find dull. Affiliate tracking, ticket routing, survey scoring - none of it makes a good demo-day slide. But it is exactly the kind of infrastructure businesses will pay for month after month, and the founders have spent twenty years getting good at spotting the next one.
Slovakia is not the first place most people picture when they think of global SaaS, and that is part of the story. Quality Unit has served a nine-figure user base from a tower in Bratislava, quietly demonstrating that product quality and distribution travel further than a Silicon Valley zip code. It occupies the middle of several markets rather than the top of any one - which, for a company answerable only to itself, has turned out to be a comfortable place to sit.
The FlowHunt launch is the tell for where it goes next. Most incumbents fear being disrupted by AI. A twenty-year-old support-and-affiliate-software company deciding to build the no-code AI agent platform itself is a different posture - less bracing for the wave, more trying to sell surfboards. Whether FlowHunt becomes the third pillar or a footnote, the move fits the pattern: find the workflow everyone will soon need, and quietly build the tool for it.
For anyone tired of the raise-grow-flip treadmill, there is a whole playbook hiding in this company. Pick a market nobody brags about. Do it well enough that customers stay. Use the profits to buy your next product instead of borrowing against your future. Keep the founders in the building. Twenty-two years in, Quality Unit is still the one holding the pen.
