The Company That Moves Billions of Messages You Never Notice

How a self-funded SMS gateway from a Croatian fishing town became the plumbing behind hundreds of billions of texts, WhatsApp messages and login codes.

The first message Infobip ever sent was a Christmas text. It went out from the town hall of Vodnjan, a Croatian town of about six thousand people, to the locals who had scattered abroad and wanted a word from home. There was no company yet, no funding round, no category to belong to - just an engineer named Silvio Kutic tinkering with the idea that you could move information between people using the phone in their pocket.

Twenty years on, that tinkering is a global business. Infobip runs a cloud communications platform that lets companies talk to their customers over SMS, WhatsApp, RCS, voice, email and roughly every other channel a phone can carry. If you have ever received a one-time login code, a "your driver is two minutes away" ping, or a delivery receipt on WhatsApp, there is a decent chance the message passed through infrastructure like Infobip's on the way to you.

01 / WHAT IT DOESThe business of being the pipes

The category has an unlovely acronym: CPaaS, or Communications Platform as a Service. Stripped of the jargon, it means Infobip sells businesses a way to reach people at scale without each company having to negotiate its own deals with mobile carriers around the world. A developer plugs into Infobip's APIs, writes a few lines of code, and can suddenly send a text to a phone in Nairobi, Jakarta or São Paulo - and get the reply back.

Underneath, the work is unglamorous and enormous. Infobip has struck direct interconnect agreements with more than 800 mobile operators, which is what lets it reach a large share of the world's mobile subscribers. That carrier network is the moat. Anyone can write a messaging API; far fewer can guarantee your bank's login code actually lands, in the right country, in under a second, every time.

02 / THE CUSTOMERSWho is actually paying

Infobip's customers are businesses, not consumers - which is exactly why most people have never heard of it. Banks use it to send transaction alerts and two-factor codes. Retailers use it for order updates and promotions. Ride-hailing and delivery apps, including Uber, use it for the constant back-and-forth of a live order. Brands like Burger King run marketing campaigns across channels through it. Telecom operators, oddly, are customers too: Infobip helps them monetise the very application-to-person traffic that runs over their networks.

The common thread is volume. These are companies that need to send not thousands of messages but hundreds of millions, reliably, across borders, with compliance and fraud controls baked in. That is the problem Infobip solves - and it is a problem that only gets bigger as more of commerce moves onto messaging.

03 / THE PROBLEMWhy global messaging is hard

Sending one text is trivial. Sending a billion, across two hundred countries, each with its own carriers, regulations, spam filters and pricing, is a logistics problem dressed up as a software problem. A message that fails to deliver a password reset is a locked-out customer. A message that arrives late during a fraud alert is a security hole. A campaign that trips a carrier's spam rules can get a brand's traffic blocked in an entire market.

Infobip's pitch is that it absorbs all of that. It handles the routing, the failover between carriers, the number validation, the fraud and firewall layer, and the regulatory maze - so its customers can treat "reach any human on earth" as a single API call rather than a hundred separate telecom projects.

04 / THE DIFFERENCENot the loudest, often the largest

In the United States, the poster child for this category is Twilio - developer-beloved, publicly traded, loud. Infobip took a quieter path. It stayed private, stayed profitable, and leaned into the parts of the world where reach is hard and margins are won by owning carrier relationships directly, especially across emerging markets. The result is a company that rarely trends on tech Twitter but moves message volume at a scale few rivals match.

Its other distinguishing move was patience with capital. Infobip was bootstrapped - no outside investment at all - for its first fourteen years, funding growth from revenue. Most startups raise early and often; Infobip raised late and rarely, which left its founders in control and its strategy long-term.

05 / PRODUCTSFrom pipes to platform

For years Infobip was, essentially, the pipes. Then it started climbing the stack. Around 2019 it launched three software products that turned raw messaging into usable tools: Moments, for building marketing campaigns and customer journeys across channels; Answers, for building chatbots; and Conversations, a cloud contact centre that pulls every channel into one agent screen. Alongside those sit its authentication business - the two-factor codes and one-time passwords behind everyday logins - and a fraud-prevention layer built partly on its 2021 acquisition of the SMS-firewall specialist Anam.

The strategy is clear: sell the connectivity, then sell the software that makes the connectivity worth more. A per-message API is a commodity; a marketing platform or a contact centre is a subscription with stickier margins.

06 / THE MODELToll-booth economics

Infobip makes money in two overlapping ways. The first is usage: it charges per message or interaction across SMS, WhatsApp, RCS, voice and email, buying network capacity in bulk and reselling it at scale. The second is software: subscriptions for Moments, Answers, Conversations and its authentication and fraud tools. It is a toll-booth business at its core - it does not own the customer relationship or the app, only the connection between them - but it collects on volume that runs into the hundreds of billions of interactions a year.

07 / EXPERTISE & EXPANSIONThe acquisition sprint

Between 2020 and 2022, Infobip went shopping. It acquired the US messaging firm OpenMarket (reported at around $300M) to deepen its American footprint, bought Anam to own the fraud-and-firewall layer, picked up the developer-focused Shift conference, and completed the purchase of Peerless Network to add US voice capacity and global network reach. Three acquisitions in three years turned a messaging company into a fuller communications cloud - and did it fast.

08 / THE MARKETWhere it sits now

Infobip has been named a Leader in the CPaaS market by Gartner, IDC and Omdia across multiple years, and in 2025 landed on Fortune's list of Europe's most innovative companies. Its bet for the next chapter is that AI agents - software that can hold a real conversation with a customer - will run on exactly the messaging rails it already owns. The company predicts AI could handle the large majority of customer engagements within a few years. Whether that number holds or not, the strategic logic is sound: if conversations move to bots, the company that carries the conversations is well placed.

For a business that began with a single Christmas text from a small-town hall, the ambition is striking - and the geography is the quiet lesson. Infobip is proof that the infrastructure of the internet can be built anywhere the code runs, and that a company far from the usual tech capitals can end up carrying a meaningful slice of the world's messages.
