Naveen Tewari, Abhay Singhal, Amit Gupta and Mohit Saxena launched mKhoj in Mumbai in 2007 to provide local search, services and deals through SMS. When too few people used it and cash was running low, the team pivoted to mobile advertising, renamed the business InMobi in 2009 and expanded internationally. A $200 million SoftBank investment completed on 15 September 2011 put the company at roughly the $900 million-to-$1 billion valuation threshold and established it as India’s first unicorn.
mKhoj was the original company
InMobi’s official company history identifies mKhoj as the venture founded in Mumbai in 2007. The name reflected an SMS-based search and monetization model: a user could send a request from a mobile phone and receive information about nearby services, offers or coupons. At a time when mobile access was spreading faster than consumer internet services, the founders saw SMS as a practical distribution channel.

Tewari later described the idea as a response to the rapid growth of mobile phones and the relatively slow development of mobile content. The company was not initially building an advertising network. It was trying to make local information and deals available through text messages and then monetize that activity.
Why the SMS model failed to gain traction
The first model did not collapse through a reported insolvency or formal shutdown. It produced insufficient usage. In a 2009 account, Tewari wrote that the team discovered demand was too weak; an Economic Times report published on 21 October 2011 quoted him saying that traction for local search and coupons was “not as high as initially anticipated” within six months.
#1 Best Overall
That distinction matters. “Failed SMS startup” describes mKhoj’s weak product-market fit, not a company that disappeared. The founders were still able to reassess the market, preserve the business and redirect its resources while cash was becoming scarce.
The pivot: from answering SMS queries to powering mobile advertising
The team concluded that the larger opportunity was not a narrow local-search service but the mobile ecosystem itself. Tewari summarized the bet in a 2011 Bloomberg interview transcript published by InMobi: “The key thing about this space is the whole user base was going to shift to mobile.”
Instead of waiting for consumers to text a local query, the company moved toward the infrastructure needed by advertisers and publishers reaching mobile users. That change altered the customer, product and revenue logic at the same time:

The company rebranded from mKhoj to InMobi in 2009 to reflect that broader mobile-advertising mission. The new name was more suitable for an international business than one associated with an India-focused SMS search service.
How the company moved from pivot to global scale
2007: mKhoj launches in Mumbai
The four-person founding team—Tewari, Singhal, Gupta and Saxena—started with SMS search and monetization. The initial concept focused on local information and nearby offers.
Within months: the founders reassess the model
By roughly six months, and certainly within the first year, usage was below expectations. The team spent intensive time examining the weak response and selected mobile advertising as the new direction.
2009: mKhoj becomes InMobi
The rebrand marked the strategic shift from a consumer SMS service to a mobile advertising company designed for a wider market.

InMobi’s official history says the company entered North America and raised Series B funding in 2010. This was a step toward the international footprint that the new advertising model required.
15 September 2011: SoftBank investment closes
InMobi and SoftBank completed a $200 million investment on 15 September 2011, according to contemporary Economic Times and Livemint reporting. The funding round placed the business near the valuation level later associated with unicorn status.
Why 2011 was the unicorn milestone
InMobi is identified by its own 2022 milestone release and institutional accounts as India’s first unicorn in 2011. Those sources use a $1 billion valuation for the milestone. The contemporaneous Economic Times report described an estimated valuation of about $900 million around the SoftBank round, while later accounts use the rounded $1 billion figure.
Both figures refer to the same historical transition: the SoftBank-backed financing showed that a company born from an underperforming Indian SMS product had become a globally relevant mobile-advertising business. The difference is a matter of reporting and valuation terminology, not evidence of two separate pivots.
What the user numbers show—and what they do not
In a June 2011 Knowledge at Wharton interview, InMobi was reported to have 315 million users in more than 140 countries. A 2013 McKinsey account cited almost 700 million users across more than 160 countries. These are dated snapshots, not current user totals, and they illustrate the speed and scale of the international expansion after the pivot.
Best Value
The figures also explain why the advertising model was more scalable than the original SMS service. A local search product had to attract repeated queries in each market. An ad network could serve advertisers and publishers across countries as mobile usage expanded, allowing the same underlying infrastructure to support a much larger audience.

The ₹3,000-crore description in the headline is not supported by the valuation figures reported in the cited historical accounts. Livemint’s 2020 article converted the $1 billion milestone to approximately ₹7,115 crore. The Economic Times’ 2011 report instead used an estimated $900 million valuation at the funding round.
Because exchange rates and valuation estimates vary by date and source, the defensible description is that InMobi reached the $900 million-to-$1 billion range around the September 2011 SoftBank investment and is widely recognized as India’s first unicorn. Converting that milestone into rupees should be presented as a dated approximation, not as a fixed ₹3,000-crore valuation.
The repeatable business lesson in InMobi’s origin story
- Start with a real behavior, then measure usage. Mobile-phone growth alone did not create enough demand for mKhoj’s SMS search product.
- Treat weak traction as evidence. The founders changed the model while cash was running low instead of defending a product customers were not using.
- Follow the larger ecosystem. The pivot targeted the shift of users to mobile, not merely a different way to deliver local search.
- Match the brand to the market. The 2009 InMobi name signaled a global mobile mission rather than an India-only SMS service.
- Use scale as the validation test. International expansion, user growth and the 2011 SoftBank financing provided stronger evidence than the original local-search metrics.
InMobi’s path was therefore not a straight-line success. It was a sequence: mKhoj’s SMS experiment, a rapid diagnosis of weak demand, a mobile-advertising pivot, an international expansion and a 2011 financing event that crossed the unicorn threshold. That sequence is how Tewari and his co-founders turned an initially unsuccessful product into the company recognized as India’s first unicorn.
