Perplexity’s Airtel giveaway in India grew users fast—yet the real test is whether free cohorts will keep paying after the free year ends

Perplexity is leveraging Bharti Airtel’s massive customer base to distribute its paid AI-search experience at near-zero upfront cost to users. In July 2025, Airtel partnered with Perplexity to offer a 12-month Perplexity Pro subscription (normally priced at ₹17,000 for a year) to Airtel customers, targeting a potential audience of 360 million users.

The key investor takeaway isn’t the headline “free AI” marketing—it’s the measurable impact on app behavior during the giveaway window. A TechCrunch report citing Sensor Tower/Appfigures-style analytics says Perplexity’s India downloads spiked during the promo period, with monthly active users rising sharply while the promotion was live.

During the promotional period, the reported direction of travel supports a comforting narrative for AI-search operators: free-tier distribution can scale usage without immediately destroying willingness-to-pay signals. A TechCrunch report (citing Sensor Tower analytics) states that estimated in-app purchase + subscription revenue in India rose about 60% during the relevant period when the Airtel offer was available to new users.

But investors should treat that as an early monetization “signal,” not the final verdict. The same reporting emphasizes that the measurement cannot cleanly separate Airtel-driven new subscribers from existing paying users, and it cannot fully disentangle whether higher revenue came from users choosing to pay versus users failing to cancel quickly enough before billing triggers.

AI search monetization is not just about model quality. The supply-chain reality is that the “front door” is often controlled by distribution partners (telecom, app stores, browser defaults, and device-level surfaces). Perplexity’s Airtel offer is a textbook example: the product is delivered through a telecom channel that can place an AI assistant directly into the daily habits of hundreds of millions of users.

In that model, the competitive fight vs. Alphabet’s core search ecosystem shifts from ranking games to funnel economics. Free distribution can increase query volume and data flywheel activity, but monetization depends on whether users cross the threshold from “entitled curiosity” to recurring payment.

So the real strategic question is: does the funnel have a stable conversion rate when subsidies end, or does it collapse back toward baseline—leaving only a short-lived usage spike?

A major reason this matters to Alphabet and other search incumbents is that emerging markets magnify distribution leverage. When users are price sensitive, charging for AI answers early can suppress adoption. Subsidized access can raise query share fast—but only recurring monetization determines whether that query share becomes durable revenue.

Until Perplexity demonstrates stable cohort conversion after freebies end, the most investment-relevant interpretation is that Perplexity is proving distribution capability, while the monetization engine remains under a strict validation clock.
