True North Acquires $50-$60 Mn Stake in InMobi as Adtech Unicorn Accelerates $1 Bn IPO Preparations

BENGALURU — In a major pre-IPO secondary market transaction, prominent domestic private equity firm True North has acquired a minority stake in SoftBank-backed adtech unicorn InMobi. Valued between $50 million and $60 million, the deal allows several early-stage backers of the advertising technology pioneer to secure partial liquidity as the company methodically lays the groundwork for a blockbuster public market debut.

According to people familiar with the development, the transaction primarily involves secondary share purchases, with True North securing a 2% to 3% equity stake in the Bengaluru-headquartered enterprise. A minor primary capital infusion component was also integrated into the overall deal structure.

The transaction underscores a broader trend within the Indian technology and startup ecosystem: late-stage domestic institutional investors are increasingly stepping in to provide structured liquidity to early venture capitalists and angel investors, mitigating public market transition anxieties and helping stabilize shareholding cap tables ahead of imminent initial public offerings (IPOs).

Main Facts

The core elements of the strategic investment underline InMobi’s shifting financial dynamics and preparation for public markets:

• Investor Profile: True North, a leading Indian private equity fund known for its deep investments across financial services, healthcare, consumer, and technology sectors, is the buyer.
• Transaction Size and Scale: The deal is valued between $50 million and $60 million, translating to a 2% to 3% ownership stake in InMobi.
• Transaction Structure: The vast majority of the capital was deployed via secondary share purchases—buying out early investors seeking exits—complemented by a smaller primary capital injection.
• Corporate Backing: InMobi remains a heavily institutionalized enterprise, counting global heavyweights such as SoftBank, Sherpalo Ventures, and Kleiner Perkins among its long-term backers.
• Public Market Ambitions: The transaction unfolds as InMobi actively structures its corporate redomiciling from Singapore back to India, aiming to file its draft red herring prospectus (DRHP) for a massive $1 billion public offering.

Chronology of Events: From Inception to Pre-IPO Maneuvers

To understand the gravity of True North’s recent entry, it is essential to trace InMobi’s nearly two-decade trajectory—from a pioneering mobile advertising startup to a sprawling global ecosystem encompassing adtech, artificial intelligence, and social commerce.

1. The Foundation and Early Growth (2007–2015)

InMobi was founded in 2007 by a cohort of visionaries—Naveen Tewari, Piyush Shah, Mohit Saxena, and Abhay Singhal. Initially launching as an SMS-based search platform called mKhoj, the founders quickly recognized the structural shift toward mobile application ecosystems. Pivoting into a mobile advertising network, InMobi scaled rapidly across emerging and developed markets.

By the early 2010s, the company had captured the attention of marquee Silicon Valley and global investors, raising substantial capital rounds from firms like Kleiner Perkins and Sherpalo Ventures. In 2011, InMobi achieved unicorn status—becoming one of India’s earliest tech startups to cross the elusive $1 billion valuation threshold—bolstered by a monumental $200 million investment from Japanese telecom and investment giant SoftBank.

2. Diversification and Ecosystem Expansion (2016–2023)

Rather than resting on its laurels as a pure-play adtech network, InMobi aggressively expanded its technological boundaries. The enterprise spun out and scaled two major consumer-facing platforms:

• Glance: An AI-driven lock-screen content and commerce platform that transforms Android smartphones into dynamic content hubs without requiring users to unlock their devices. Glance achieved hyper-growth, securing backing from tech titans like Google and Jio platforms.
• Roposo: A social commerce and creator-driven video platform designed to capitalize on India’s booming short-video economy.

Cumulatively, InMobi has raised upwards of $774 million across its lifetime from a stellar roster of global funds, cementing its position as a cornerstone of India’s digital economy.

3. Recent Structural Overhauls and Buybacks (2024–2025)

The past eighteen months have marked a period of intensive corporate restructuring for InMobi as it readies itself for public scrutiny:

• Founder Buybacks: In a rare and bold move demonstrating absolute confidence in the company’s fundamentals, InMobi’s cofounders injected approximately $3.7 million of their own capital in mid-2024. Shortly thereafter, they orchestrated a massive buyback, repurchasing a 25% to 30% stake previously held by SoftBank, thereby consolidating promoter ownership.
• Geographical Migration: Mirroring a trend observed across top-tier Indian startups—such as PhonePe, Pine Labs, and Zepto—InMobi initiated the complex legal and financial process of redomiciling its corporate headquarters from Singapore back to India. This shift is widely viewed as a strategic prerequisite to appeal to domestic mutual funds, retail investors, and regulatory bodies during its forthcoming domestic IPO.
• Strategic Acquisitions: In early 2025, InMobi continued to sharpen its competitive edge by acquiring San Francisco-based mobile app marketing and analytics platform MobileAction. This acquisition significantly augmented InMobi’s capabilities in bridging brands with iOS users, enhancing its unified adtech proposition.

Supporting Data and Financial Metrics

InMobi operates in a highly dynamic, competitive, and technologically demanding environment. Evaluating the scale of True North’s investment requires looking at the broader financial context of the firm:

• Total Historical Funding: Over $774 million raised since inception.
• Current Stake Valuation: True North’s $50-$60 million infusion for a 2-3% stake places InMobi’s overall valuation within a competitive private market bracket. While market whispers over the past two years pegged InMobi’s desired IPO valuation between $8 billion and $10 billion, subsequent valuation corrections across global tech markets have adjusted expectations closer to the $6 billion mark.
• Investment Syndicate: Key legacy investors include SoftBank Group, Sherpalo Ventures, and Kleiner Perkins, alongside the substantial skin-in-the-game demonstrated by cofounders Naveen Tewari and his leadership team.
• Advisory Lineup: To steer its $1 billion public float, InMobi has reportedly tapped a heavyweight roster of global and domestic financial institutions, appointing JPMorgan Chase & Co, Jefferies, Kotak Mahindra Capital, and Axis Capital as the merchant bankers overseeing the IPO mandate.

Official Responses and Market Perspectives

As of publication, official commentary from InMobi regarding the specific terms of True North’s secondary purchase remains limited. Inc42 and financial news desks have reached out to corporate communications teams for detailed insights into the valuation parameters and the identities of the early investors who utilized the True North transaction to execute partial exits.

However, industry analysts have been vocal about the strategic implications of the deal:

1. Venture Capital Liquidity: For early-stage venture funds that backed InMobi more than a decade ago, finding liquidity paths can be complex given the shifting macro-economic climate for global IPOs. Private equity firms like True North stepping in for secondary tranches provide vital relief, allowing early backers to return capital to their limited partners (LPs).
2. Validation of Domestic Capital: The inclusion of a premier domestic PE fund like True North signals a structural maturing of the Indian capital ecosystem. Historically reliant on foreign sovereign wealth funds and Western crossovers, late-stage Indian tech giants are increasingly finding institutional muscle right at home.

Implications of the Deal

The True North investment is far more than a routine cap table adjustment; it carries profound implications for InMobi’s upcoming IPO, the domestic adtech sector, and India’s broader tech market landscape.

1. Paving the Way for a Clean IPO Cap Table

By facilitating early investor exits and allowing cofounders to previously claw back significant equity from SoftBank, InMobi is engineering a clean, simplified cap table. Public market investors—particularly conservative institutional mutual funds—frequently favor companies where promoter conviction is high and legacy venture capital overhang is minimized. True North’s entry as a respected institutional anchor further strengthens governance optics ahead of the DRHP filing.

2. Doubling Down on AI and Global Competitiveness

Adtech is undergoing an unprecedented paradigm shift driven by generative AI, privacy-first data regulations (such as Apple’s App Tracking Transparency framework), and the decline of third-party cookies. InMobi’s recent acquisitions, such as MobileAction, alongside its deep-tech integration within Glance and Roposo, require sustained capital expenditure. The primary component of True North’s investment, coupled with InMobi’s existing cash reserves, ensures the company remains well-funded to out-innovate global competitors.

3. Testing the Waters for a $1 Billion Public Float

With an intended issue size crossing the $1 billion mark, InMobi’s IPO will stand as one of the largest tech offerings originating from India. The macro-economic reception of the issue will serve as a bellwether for investor appetite toward profitable, scaled-up adtech and software-as-a-service (SaaS) hybrids. While global market volatility means timelines are fluid and subject to regulatory scrutiny, the involvement of elite merchant bankers and sophisticated private equity partners like True North suggests that InMobi’s public market machinery is operating at full throttle.

Conclusion

True North’s $50–$60 million secondary acquisition marks a vital milestone in InMobi’s maturation into a publicly traded powerhouse. By balancing early investor liquidity needs with strategic corporate restructuring, InMobi is methodically positioning itself for its next great leap. As the adtech unicorn finalizes its redomiciling and inches closer to filing its draft papers with market regulators, all eyes will remain on Bengaluru to see how this pioneer charts the course for India’s next wave of mega tech IPOs.
