Startup Deep Dive : Route Mobile — the messaging pipe a European telecom bought for more than it is worth today

In May 2024, a Belgian telecom group paid close to Rs 8,516 crore to take control of Route Mobile, an Indian messaging company that started in 2004 with Rs 1 lakh and a second-hand computer its founder took in place of an unpaid freelance fee. Two years later, the whole of Route Mobile trades on the stock exchange for barely a third of what that buyer paid for a majority stake alone — Rs 2,926 crore, as of 18 September 2026.

That gap is not a scandal. It is what happens when a founder-run cloud communications business sells near the top of a cycle, and the new owner then meets a business with structurally thin, telecom-operator-controlled margins. Route Mobile sends the one-time passwords, delivery alerts and WhatsApp order confirmations that arrive silently behind the apps of Indian banks, airlines and e-commerce firms, and of enterprises worldwide. By FY25 that plumbing had generated Rs 4,575.62 crore (about $476.6 million) in revenue. The same year, profit fell. A year later, a security incident at a Latin American subsidiary knocked a chunk off margin in a single quarter. This is the story of two brothers who built a wholesale messaging pipe good enough for a European telecom major to buy outright — and what happened to it once control changed hands.

Quick facts

What they do

Route Mobile sells the infrastructure that lets banks, telecom operators, e-commerce platforms and airlines talk to their customers at scale over SMS, WhatsApp, RCS, voice and email — the one-time password on a login screen, the “your order has shipped” text, the flight-delay alert. It is a Communications Platform as a Service, or CPaaS, provider: enterprises plug into its APIs instead of building their own connections into hundreds of telecom networks around the world, and Route Mobile handles the routing, compliance and delivery across more than 20 countries in Asia-Pacific, the Middle East, Africa, Europe and the Americas.

The origin

Rajdip Gupta started Route Mobile from a bedroom in Mumbai in May 2004, after returning from a stint in the UK, with about Rs 1 lakh (roughly $2,000) saved from freelance software work. In one early job, a client who could not pay in cash gave him a second-hand computer instead — an Intel 486 machine with 4 MB of RAM and a 16 GB hard drive, bought for around Rs 6,500. The founding insight was narrow but well-timed: mobile operators in Europe and India were sitting on SMS capacity they could not sell efficiently to businesses, and nobody had built a simple reseller layer on top of it. Gupta built a platform that let clients rebrand it for about $1,000 and send 100,000 messages, effectively franchising access to bulk messaging capacity before “API-first” was a category. A year in, revenue had reached about Rs 1 crore with roughly Rs 50 lakh in profit. In 2005, his brother Sandip Gupta, a chartered accountant who had trained at PwC, joined to run finance and operations, splitting the company into a technology side and a numbers side from the start.

The struggle years

The company’s own founders describe its first decade as one of near-total austerity rather than any single collapse: for ten years after incorporation, Rajdip and Sandip Gupta drew an annual salary of only Rs 12,000 each, ploughing every rupee of profit back into servers, licences and new country registrations rather than into themselves. Route Mobile did not raise any outside capital in that period — its first institutional money came only in February 2017, thirteen years after founding, when the Shrem Group bought a 10% stake for $23 million. That gap mattered: it meant every expansion — the 2011 London office, the first Indian SMSC hosted with Loop Mobile in 2010, the enterprise business division set up in 2012 — was funded out of thin operating margins in a business where telecom operators, not Route Mobile, set the wholesale price of the underlying network capacity.

The second, more recent struggle sits on the other side of the company’s biggest triumph. In FY25, the first full year under Proximus, revenue rose 13.7% to Rs 4,575.62 crore, but net profit fell 14.1% to Rs 333.93 crore — a company under new ownership growing its top line while its bottom line went the other way. The pattern repeated in the June 2026 quarter (Q1 FY27), when adjusted EBITDA margin compressed to 9.5% from 11.9% the previous quarter, missing management’s own 12% target, and gross margin fell to 20.9% from 23.3% sequentially. Management attributed part of the damage to a security incident at Masivian, its Colombian subsidiary, which “marginally impacted gross profit,” alongside a transitory traffic pullback at one large customer account awaiting a new solution deployment.

The turning point

The defining event in Route Mobile’s history is not the 2020 IPO but the sale of the company itself. On 17 July 2023, Proximus Group signed a definitive agreement with the founding shareholders — the Gupta family and associated promoters — to acquire their entire 57.56% stake through a newly formed vehicle, Proximus Opal, for INR 59,224 million (EUR 643.0 million) in cash, at Rs 1,626.40 per share. Under Indian takeover rules, that trigger forced a mandatory open offer for a further 26% of public shares at the same price; the offer drew 24.99% of the company, adding another INR 25,934 million (EUR 292.8 million). Some of the founding shareholders then chose to reinvest EUR 299.6 million of their proceeds back into Proximus Opal itself, taking a 12.72% stake in the new parent rather than walking away entirely. The transaction closed on 8 May 2024, leaving Proximus Opal holding 82.70% of Route Mobile for a combined cash outlay of roughly Rs 8,516 crore (about EUR 935.8 million gross, EUR 636.3 million net of the founder reinvestment).

The market’s own reaction was telling: Route Mobile’s shares fell as much as 8.5% on the day the deal was announced, even though the offer price represented a premium to the pre-deal trading range — investors were pricing in the loss of founder-led growth as much as the exit value on offer. Two decades after Rajdip Gupta drew a salary of Rs 12,000 a year to keep the company alive, control passed out of the family’s hands in a single signature.

The money behind it

Route Mobile is unusual among Indian technology companies for how little venture capital it needed. It ran on internal accruals for thirteen years before taking its first outside cheque: the Shrem Group’s $23 million purchase of a 10% stake in February 2017, a growth-capital deal rather than a survival one, since the company was already profitable. It went public on 21 September 2020 with a Rs 600 crore IPO priced at Rs 350 a share, backed by anchor investors including Goldman Sachs, Franklin Templeton, SBI Mutual Fund, Axis Mutual Fund and the Kuwait Investment Authority; the stock listed at a 104.9% premium and the company’s market capitalisation crossed roughly Rs 3,800 crore on debut day. In November 2021, with the balance sheet strong and acquisitions in view, Route Mobile raised a further Rs 867 crore (INR 8,674.98 million) through a Qualified Institutional Placement, drawing in Steadview Capital, RBC’s Asia-Pacific equity fund and Societe Generale, among others — capital that funded the $47.5 million purchase of Colombia’s Masivian later that year to build a Latin American footprint.

The single largest capital event, though, dwarfs all of that: Proximus Group’s roughly Rs 8,516 crore purchase of 82.70% control in 2023–24, which turned a widely held listed Indian company into a majority-owned subsidiary of a Belgian telecom group. Proximus has since folded Route Mobile into a wider bet: it already owned Telesign, a digital-identity and fraud-prevention business bought for $230 million in 2017, and BICS, an international connectivity carrier taken to full ownership in 2021. In December 2024, Proximus merged Route Mobile, Telesign and BICS into a single unit, Proximus Global, valuing the combined international arm at about EUR 3.1 billion in equity, on the back of EUR 1.9 billion of combined 2023 revenue.

How it makes money

The mechanics are simple to describe and hard to run profitably at scale. Route Mobile buys message termination and network access wholesale from telecom operators and OTT platforms such as WhatsApp, then sells that capacity onward to enterprise clients through APIs, charging per message, per minute of voice or per verification event. The company’s own FY25 numbers show gross margin sitting around 21–23% in a normal quarter, tightening or widening a few points depending on customer and country mix — a business where scale, not pricing power, is the main lever, because the underlying network cost is set by operators who compete with Route Mobile as much as they supply it.

What people typically get wrong is treating Route Mobile as a pure reseller. A meaningful share of its margin actually comes from services layered on top of raw messaging: its SMS Firewall product, deployed with Idea Cellular starting in 2018, is sold on a revenue-share basis and is reported to have recovered around Rs 100 crore in leaked or fraudulent operator revenue within two years — Route Mobile effectively gets paid a cut of money the telecom operator would otherwise have lost to grey-route fraud, rather than a fixed per-message fee. Enterprise-grade products such as its RCS business messaging, verification APIs and analytics dashboards behave more like software, with better margins than commodity SMS termination, which is why the company has kept pushing enterprise clients toward WhatsApp Business, RCS and voice rather than plain SMS.

The numbers

Figures below are consolidated revenue and profit after tax, in Rs crore, as reported for each fiscal year (April–March).

Revenue has compounded steadily through four straight years of growth, helped by acquisitions such as Masivian and continued enterprise client wins. Profit has been far less consistent: it roughly doubled from FY22 to FY23 on operating leverage, kept rising through FY24, and then fell in FY25 — the first full year of Proximus ownership — even as revenue kept climbing. The trend has continued into FY26–27: Q1 FY27 (the quarter to June 2026) posted revenue of Rs 1,151.5 crore, up 9.6% year-on-year, alongside a 40.1% sequential fall in profit after tax to Rs 68.6 crore, as margin compression from the Masivian security incident and a large-account traffic pullback worked through the numbers.

Where the money comes from

Route Mobile’s revenue is overwhelmingly international rather than domestic despite its Mumbai headquarters: in FY25, about Rs 3,790 crore of revenue came from exports against roughly Rs 785 crore from India operations. Measured a different way — by where the message is actually delivered rather than where the client is billed — India still accounts for the largest single share of traffic at about 36% of revenue by message termination, with Europe contributing around 16% and the rest of Asia excluding India about 13%; the remainder is spread across the Middle East, Africa and the Americas. Messaging services are the business almost in their entirety: of the Rs 4,575 crore in FY25 revenue, about Rs 4,498 crore came from messaging, with BPO and technical-support services making up a small remainder. The surprise for anyone assuming this is an “India story” is how thoroughly Route Mobile’s growth has depended on enterprises and operators outside India — which is also precisely the geographic spread that made it attractive to a European acquirer looking to combine assets across BICS, Telesign and Route Mobile into one global footprint.

The risks

Three risks sit closest to the surface, and each has already shown up in the company’s own recent results rather than remaining theoretical. First, customer concentration: Route Mobile’s top ten clients still account for about 43% of revenue, down from roughly 48% in earlier years but still high enough that a single account’s traffic pullback — as management explicitly flagged in the June 2026 quarter — can move company-wide margin by a full percentage point. Second, operational and security risk in a widely distributed international footprint: the security incident at its Colombian subsidiary, Masivian, directly dented gross profit in Q1 FY27, a reminder that a company running infrastructure across 20-plus countries inherits the security posture of every subsidiary and acquisition it makes. Third, regulatory and platform risk: Route Mobile operates under India’s telecom-marketing rules (the TRAI/DND framework introduced in 2010–11) and equivalent regimes abroad, carries exposure to claims if a client misuses its platform to send unauthorised messages, and — like every SMS-based messaging company — faces a structural squeeze as WhatsApp, RCS and other OTT channels increasingly let brands reach customers directly, at prices set by platform owners rather than telecom operators. Competitors including Infobip, Twilio, Gupshup and Kaleyra compete for the same enterprise contracts, keeping pricing pressure constant even as volumes grow.

The takeaway

Route Mobile’s twenty-year run says something uncomfortable about businesses built on thin, operator-controlled margins: the only real defence is scale, but scale is also what makes you worth buying. The Gupta brothers spent a decade taking home Rs 12,000 a year specifically so the company could out-survive smaller resellers and eventually out-bid them for enterprise contracts across 20-plus countries. That patience worked — Route Mobile became large enough, and global enough, for a European telecom group to want to own it outright rather than merely compete with it. But the same numbers that made the company an attractive acquisition — thin, competitive margins that depend on constant volume growth — are exactly what have made profit harder to hold onto since the sale, through a weaker FY25 and a rockier first quarter of FY27. Getting big enough to be bought is not the same as getting big enough to be safe.

Frequently asked questions

What does Route Mobile actually do?

It provides Communications Platform as a Service (CPaaS) infrastructure — APIs that let banks, e-commerce firms, airlines and telecom operators send SMS, WhatsApp messages, RCS messages, voice calls and emails to customers at scale, handling routing and compliance across more than 20 countries.

Who owns Route Mobile now?

Belgium’s Proximus Group, through its subsidiary Proximus Opal (renamed Proximus Global in December 2024), holds roughly 74.9% of Route Mobile as of June 2026, after completing the acquisition of majority control on 8 May 2024.

Why did Proximus buy Route Mobile?

Proximus wanted to combine Route Mobile’s CPaaS and messaging business with two other assets it already owned — Telesign (digital identity and fraud prevention) and BICS (international connectivity) — to build a single global digital-communications and identity group, now called Proximus Global.

Is Route Mobile still a listed company in India?

Yes. Route Mobile remains listed on the BSE and NSE, where it debuted on 21 September 2020; the Proximus transaction made it majority-owned rather than delisted, and its market capitalisation stood at Rs 2,926 crore as of 18 September 2026.

How does Route Mobile make money?

It buys wholesale message and voice termination capacity from telecom operators and platforms like WhatsApp, then resells that capacity to enterprise clients via APIs at a markup, supplemented by higher-margin, revenue-share products such as its SMS Firewall and enterprise messaging analytics.
