Doubtnut, an India-based startup which wants to teach math and science concepts through short videos, raises $15M Series A led by Tencent, says it has 13M MAU

Context & Ripple Effects
Doubtnut is betting that short explainer videos, not live tutors, are the cheapest way to teach math and science at scale in India — and its 13 million monthly active users give that bet an audience before the money arrives. Tencent leading the round puts one of China's largest consumer-internet investors behind an Indian K-12 app early in its life.
The raise lands mid-wave: within months, Vedantu pulls in a $100M Series D at a $600M valuation and Cuemath raises a $40M Series C, while Teachmint builds teacher-side infrastructure across two rounds. Doubtnut's own arc continues with a $31M Series B led by Lupa Systems and SIG a year later, confirming investor appetite for the format.
First-order effects
- Tencent gets an early position in Indian consumer edtech through a lead role rather than a follow-on, while Doubtnut gains the capital to expand its video library and keep serving a free-to-use base of 13M MAU.
Second-order effects
- Live-tutoring platforms like Vedantu and Cuemath face a free, self-serve alternative for concept clarification, pressuring them to justify paid tutoring on depth and personalization rather than basic doubt-solving.
Third-order effects
- If short-form video keeps attracting both users and capital — as Numerade's subscription-based STEM video round in the US suggests — education splits into a low-cost video layer beneath premium live instruction, reshaping how edtech startups price and segment.
The trend: Indian edtech is drawing large foreign-led rounds, with short-video learning emerging as the mass-market layer under premium live tutoring.
