Startup Deep Dive : Tanla — from a Rs 25 crore near-wipeout to India’s messaging backbone

Tanla Platforms routes a meaningful share of the one-time passwords, delivery alerts and bank nudges that land on Indian phones every day, yet most of the people receiving those messages have never heard the company’s name. In April 2022, Forbes India put founder Uday Reddy’s personal stake at $1.3 billion, built on a company that a decade earlier had been reduced to a market value of about ₹25 crore.

The Hyderabad-based firm is one of the larger processors of application-to-person (A2P) messaging in the world: bank one-time passwords, e-commerce delivery updates, insurance renewal reminders, all routed through its pipes between enterprises and telecom operators. It also runs Trubloq, a blockchain ledger that Tanla says scrubs a large share of India’s commercial SMS traffic for spam before it reaches a handset. Almost nobody outside telecom and enterprise-IT circles has heard of it, and that is the point: Tanla is infrastructure, not a brand.

Quick facts

What they do

Tanla sells the plumbing that lets a bank, an airline or a food-delivery app reach a customer’s phone reliably: application-to-person messaging over SMS, WhatsApp Business API and RCS (rich communication services), plus voice and email channels bundled under what the industry calls a Communications Platform as a Service, or CPaaS. Its customers are enterprises and, in turn, the telecom operators that need those enterprise messages screened for spam and fraud before they hit a subscriber’s inbox. A retail bank sending a one-time password, an insurer sending a renewal nudge, or an e-commerce company sending a delivery update is very likely to have that message pass through Tanla’s network at some point between the sender and the phone.

The origin

Before Tanla, Uday Reddy had already run two careers. He trained as a chartered accountant and, in his own account reported by Forbes India, grew disillusioned when he found some employers were “only interested in helping many evade taxes.” He moved into Hyderabad real estate instead, using his accounting background to properly document property deals in a market where paperwork was often an afterthought, and built meaningful wealth through the early-to-mid 1990s. After an MBA at Manchester Business School, he noticed something specific: Indian mobile subscriptions were exploding in the late 1990s, but text messaging itself was barely used. “In business school, we used to send SMSes to our friends. When I came to India, nobody was using text,” Reddy told Forbes India. That gap between an infrastructure everyone would soon need and a market that had not yet discovered it became Tanla, founded in May 1999 and listed on the BSE and NSE in December 2006.

The struggle years

Tanla’s history includes at least one near-total wipeout. In June 2008, at the height of pre-crisis optimism, the company paid roughly $15.8 million (about ₹80 crore at the time, per Business Standard) for an 85% stake in Openbit Oy, a Finnish mobile-payments and device-software firm serving Nokia and BlackBerry handsets; it bought the remaining stake in follow-on tranches through April 2010. Forbes India later put Tanla’s total commitment to the Openbit bet at around ₹260 crore. The wager assumed that Nokia- and BlackBerry-class devices would remain the industry standard. They did not: Apple’s and Samsung’s smartphones reset the market within a few years, Openbit’s addressable business evaporated, and Tanla’s valuation, in Reddy’s own description to Forbes India, collapsed from being “a billion-dollar company” to a market capitalisation of about ₹25 crore by 2012 — a near-total erasure of shareholder value.

A second, gentler but still real setback came a decade later. After the stock had rallied to roughly ₹1,880 in December 2021 on enterprise-messaging enthusiasm, consolidated net profit fell to ₹448 crore in FY23 from ₹539 crore in FY22 (Screener.in, compiled from company filings) as pricing pressure hit the core SMS business. The share price gave back most of its gains, touching a 52-week low of ₹506.10 on 27 March 2023, a drawdown of roughly 73% from the December 2021 peak, before recovering through 2023 and 2024 as the enterprise and Trubloq businesses scaled.

The turning point

The event that separated the two eras of Tanla’s history was the acquisition of Karix Mobile, announced in August 2018 and closed in April 2019. Tanla paid about ₹340 crore in enterprise value to buy Karix (formerly mGage India, itself a former Blackstone/GSO Capital Partners portfolio company) using internal accruals and roughly 80% cash consideration, according to Tanla’s own newsroom disclosures. Karix brought roughly 1,500 enterprise clients across banking, insurance, retail, FMCG, social media and government, and shifted Tanla’s centre of gravity away from being primarily a telecom-facing bulk-messaging vendor toward an enterprise CPaaS provider. On one side of that ledger sat a company that had been valued at about ₹25 crore only six years earlier; on the other, within roughly three years, sat a business Forbes India valued at ₹20.7 thousand crore in April 2022, when it estimated Tanla was processing about 169 billion messages a year with roughly 40% share of India’s A2P messaging market. The market cap has since cooled a great deal from that 2022 peak, but the underlying business the Karix deal built — enterprise messaging, not bulk telecom SMS — is still the one Tanla runs today.

The money behind it

Tanla’s growth was not venture-funded in the way most companies profiled in this series were built. It raised its initial public capital in a December 2006 listing and has since financed expansion mainly through operating cash flow and, occasionally, debt for acquisitions, rather than through named private-equity or venture backers. The two moves that reshaped the business were both acquisitions funded largely from internal accruals: the ₹340 crore purchase of Karix Mobile from GSO Capital Partners (a Blackstone affiliate) in 2019, which built the enterprise-messaging base described above, and a $42 million (about ₹346 crore) purchase of the ValueFirst Group from Twilio in 2023, which added omnichannel messaging clients and further international reach, according to company disclosures compiled on Wikipedia. There is no “total raised” in the venture-capital sense; the closest equivalent is the roughly ₹340 crore plus ₹346 crore Tanla has spent buying its way into new client bases since 2019, funded from its own balance sheet. The company describes itself as debt-free as of its FY26 results, and in 2025 it ran a ₹175 crore share buyback at ₹875 per share, a capital return that would not have been available to a company still dependent on external funding.

How it makes money

The mechanics are closer to a toll road than to a media or advertising business. An enterprise — a bank, an airline, a retailer — pays Tanla per message (or per interaction, for richer channels like WhatsApp) to reach its customers. Tanla’s principal cost is what it pays telecom operators to terminate those messages on their networks; the difference between what it charges the enterprise and what it pays the telco is its margin. On the domestic SMS side that spread has thinned over the years as termination pricing and competition have hardened, which is one reason the company has pushed into higher-margin channels: WhatsApp Business API messaging, RCS, and Trubloq, its blockchain-based spam-scrubbing layer that it operates for telecom networks rather than for the sender. The part outsiders most often get wrong is treating Tanla as a marketing or bulk-SMS company that blasts promotional texts to consumers. It is closer to being invisible transaction infrastructure: OTPs, delivery notifications, fraud alerts and service messages that a regulated business is required, or strongly incentivised, to deliver reliably, which is a stickier and more defensible business than promotional messaging.

The numbers

Table amounts are consolidated, in ₹ crore, compiled from Screener.in’s collation of company filings and from FY26 results coverage.

Revenue has grown every year in this stretch, including 9.7% growth in FY26 over FY25. Profit has been far less consistent: it fell in FY23, recovered in FY24, dipped again in FY25, and was almost flat in FY26, up only 0.4% on FY25 despite the double-digit revenue growth. That gap between rising revenue and stalling profit is the clearest sign in the numbers of the margin pressure discussed below; quarterly results through FY26 showed operating margin easing further, to about 16.5% in the September 2025 quarter from 17.5% a year earlier, as per result-analysis coverage from MarketsMojo.

Where the money comes from

Tanla does not break out revenue by country in a way that is easy to summarise publicly, but it does disclose a channel mix, and that mix is shifting. Contribution from OTT channels — principally WhatsApp Business API and RCS, as opposed to plain SMS — rose from 23% of revenue to 31% year-on-year through FY26, according to FY26 results coverage. That is the surprise in the split: a company most people would still associate with SMS is generating a growing share of its money from the same rich-messaging channels that were supposed to make traditional A2P SMS obsolete. Geographically, the company has been trying to rebalance away from India, pushing into Southeast Asia, the Middle East, the United States and Europe, with a new Indonesian subsidiary set up during FY26 as a base for further expansion — though the domestic Indian A2P and enterprise business still supplies the large majority of revenue today.

The risks

Three risks stand out, and the company itself discloses the first two. First, customer concentration: FY26 filing-based coverage puts the top two customers at more than 86% of consolidated revenue, meaning a pricing renegotiation, a shift of volume to a competing vendor, or financial distress at either client would move Tanla’s results immediately and by a large amount. Second, margin pressure in the traditional SMS business: international long-distance and domestic SMS termination pricing has been correcting, and enterprises increasingly have the option to move traffic to OTT channels, both of which have pushed operating margin down from about 22% in FY22 to the mid-16% range through FY26, per Screener.in figures and MarketsMojo’s quarterly result analyses. Third, regulatory dependency: Trubloq’s central role rests on India’s telecom-regulator-mandated distributed-ledger scrubbing regime for commercial messaging; a change in that regime, or telecom operators building equivalent scrubbing capability in-house, would weaken a moat that today gives Tanla a privileged, largely non-replicable position between enterprises and networks. Cross-border expansion carries a related risk: international deal closures, such as ValueFirst’s international book, have reportedly been slowed by regulatory clarifications in specific markets, illustrating how dependent even the growth strategy is on regulatory timing outside the company’s control.

The takeaway

The transferable lesson from Tanla is not about messaging technology; it is about what a near-total loss of shareholder value does and does not destroy. The Openbit bet cost Tanla almost all of its market value by 2012, but it did not cost the company its core relationships with telecom operators or its understanding of message routing at scale — the asset that mattered was preserved even after the balance sheet was gutted. When Reddy redeployed capital into Karix in 2019, he was not starting over; he was pointing an intact capability at a better market. Businesses that survive a near-death experience with their core competence intact keep the option to try again with a sharper thesis. The mistake worth avoiding is the one Openbit represents: betting the company on an adjacent market (payments, in Tanla’s case) rather than on deepening the moat you already have.

Frequently asked questions

What does Tanla Platforms actually do?

It provides Communications Platform as a Service (CPaaS) infrastructure that lets enterprises send application-to-person messages — OTPs, delivery updates, alerts — over SMS, WhatsApp Business API, RCS, voice and email, and it operates Trubloq, a blockchain-based system telecom operators use to scrub commercial messages for spam before delivery.

Is Tanla Platforms profitable?

Yes. It reported consolidated net profit of ₹509 crore on revenue of ₹4,418 crore in FY26 (year ended 31 March 2026), continuing a run of profitability that has held, with some fluctuation, across at least the last four fiscal years, per Screener.in’s compilation of company filings.

What is Trubloq?

Trubloq is Tanla’s blockchain-based distributed-ledger platform that Indian telecom operators use to verify and scrub commercial SMS content for spam and fraud before it reaches subscribers; Tanla describes it as one of the largest commercial blockchain deployments in the world by transaction volume.

Why did Tanla’s stock nearly disappear in the early 2010s?

A 2008-era acquisition of Finnish mobile-payments firm Openbit, costing roughly ₹260 crore across several tranches, bet on Nokia- and BlackBerry-era device technology that smartphones from Apple and Samsung made obsolete within a few years; Tanla’s market value fell to about ₹25 crore by 2012, according to founder Uday Reddy’s account reported by Forbes India.

What are the biggest risks to Tanla’s business?

Extreme customer concentration (the top two customers reportedly account for more than 86% of revenue), margin pressure in its traditional SMS business from termination-pricing changes and OTT-channel competition, and dependence on India’s regulatory mandate for blockchain-based message scrubbing, which underpins Trubloq’s central role.
