Doubtnut Valuation: $154M Peak to $10M Sale — Full Breakdown
Doubtnut Valuation: Full Funding History, Peak Value, and the 2023 Acquisition Explained
Doubtnut, once one of India’s most closely watched edtech startups, saw its valuation swing from a peak of $154 million in January 2022 to an acquisition price of roughly $10 million in December 2023 — a fall of more than 90% in under two years. This guide breaks down every funding round, the company’s peak valuation, and what actually happened when Allen Career Institute acquired it.
What Is Doubtnut?
Doubtnut is a Gurugram-based edtech platform founded by IIT-Delhi alumni Tanushree Nagori and Aditya Shankar. The app lets students photograph a math, physics, or chemistry problem and instantly receive a video solution, using image recognition to match the question against a large pre-answered database. Its core audience was K12 students preparing for board exams and competitive tests like IIT-JEE and NEET, with especially strong traction in tier II and tier III Indian cities and regional-language users

Why Did Doubtnut’s Valuation Fall So Sharply?
Several factors are commonly cited for the drop from a $154 million peak to a roughly $10 million exit:
- The 2022–2023 edtech funding winter. Global and Indian edtech valuations were reset sharply as investor sentiment cooled after the pandemic-era boom, and free or low-monetization user bases (like Doubtnut’s) became harder to justify at high multiples.
- A largely free product with thin monetization. Doubtnut’s core doubt-solving feature was free, which drove strong user numbers (over 32 million students reached across app, web, and YouTube) but made converting that scale into revenue difficult.
- A prior failed acquisition attempt. Byju’s had reportedly been in advanced talks to acquire Doubtnut for around $130 million, later lowered to $80–90 million, before those talks fell apart over valuation disagreements — a sign the market was already discounting the company well before 2023.
- Pressure to find an exit. With runway concerns common across the edtech sector in 2023, a acquisition — even a “down round” style exit — became more attractive than raising fresh capital at a lower valuation.
The Allen Career Institute Acquisition (December 2023)
On December 4, 2023, Kota-based Allen Career Institute — primarily known for offline test-prep coaching — acquired Doubtnut in its first edtech acquisition. Neither company officially disclosed the deal size, but multiple reports, including Entrackr and The Economic Times, estimated the transaction at approximately $10 million, a steep markdown from the company’s last reported valuation.
Allen said the acquisition was aimed at strengthening its technology-led learning offerings, integrating Doubtnut’s AI-based doubt-resolution platform with Allen’s own curriculum and academic resources. The Doubtnut founding team continued with the platform post-acquisition.
