Perplexity’s free AI offer left it with millions more users in India

Perplexity's partnership with Indian telecom giant Airtel to offer free AI access proved to be a powerful growth strategy, leaving the company with a significantly expanded Indian user base and roughly 60% higher revenue even after the promotional offer closed to new subscribers.

Perplexity's decision to bundle its AI search service for free with Airtel, one of India's largest mobile carriers, has delivered lasting commercial benefits. Even after the promotion stopped accepting new users, Perplexity's India-based revenue climbed approximately 60%, suggesting that a meaningful share of users acquired through the deal converted into paying customers. Download numbers did fall once the free access window closed, which is typical of post-promotion behavior, but the underlying monetization trend tells a more positive story. The outcome highlights India as a high-potential market for AI companies willing to use creative, carrier-led distribution strategies to build an initial user base at scale.

Perplexity's tie-up with Airtel — which gave the telecom's subscribers free access to the AI-powered search platform — has turned out to be far more than a short-term marketing splash. Even now that the offer is no longer available to new Airtel customers, Perplexity's revenue generated from India has surged by roughly 60%, a figure that points to strong post-promotion retention and conversion among users who first tried the service at no cost. App download numbers have, predictably, dipped since the deal stopped enrolling new participants, but that decline is a typical artifact of any time-limited promotional window closing rather than a signal of fading product appeal.

Why it matters: India is one of the world's fastest-growing digital economies, with hundreds of millions of smartphone users who are increasingly online but historically difficult to monetize through premium subscription models. By routing distribution through a trusted, already-installed relationship — a mobile carrier — Perplexity bypassed the usual cold-start problem that plagues new apps in crowded markets. Users who might never have downloaded an unfamiliar AI tool voluntarily were instead introduced to it through a brand they already paid and trusted.

The revenue jump suggests something crucial: free trials, when delivered at the right scale and through the right channel, can generate durable paying customers rather than just inflated vanity metrics. This is a lesson that has implications well beyond Perplexity. Other AI firms eyeing emerging markets — where disposable income is more constrained but smartphone penetration is high — may look at this playbook as a template. Carrier bundling has a long history in mobile gaming and streaming, but applying it to AI services is relatively new territory.

For Perplexity specifically, India's performance also strengthens its negotiating position as it competes against larger rivals like Google and OpenAI for global market share. Demonstrating strong monetization in a price-sensitive market is a compelling proof point for investors and potential future carrier partners in other regions. The Airtel experiment may well be remembered as an early case study in how to crack emerging markets for AI products.
