Subtl

Subtl.ai was a generative AI enterprise technology startup based in Hyderabad, India, that provided an AI-powered platform for contextual document search. Founded in 2020 by Vishnu Ramesh, Manish Shrivastava, and Sarath Chandra, the company aimed to create a 'Private Google' for enterprises. The founding team combined academic and practical expertise; Ramesh was a student at BITS Pilani, Shrivastava an assistant professor at IIIT Hyderabad, and Chandra later joined as a co-founder and product engineer.

The company developed technology to help enterprises access data within large repositories of private documents, websites, and videos. Its core product was a knowledge assistant that used a retrieval language model to extract information, answer queries, and automate tasks like form filling and ticket management with high accuracy and minimal hallucinations. Subtl.ai's platform featured document comprehension, cognitive modeling, and a relevance engine to provide contextually relevant information from unstructured data sources like PDFs and Word documents. The technology was co-created with IIIT-Hyderabad, building on over 15 years of research in Natural Language Processing. The firm served clients in the banking, insurance, and education sectors, including major clients like the State Bank of India (SBI), Garden Reach Shipbuilders & Engineers, and NSE TalentSprint.

Subtl.ai's business model was B2B, generating revenue through subscriptions to its services. The startup had raised a total of $120K-$200K in funding over multiple rounds from investors including ITI Growth Opportunities, FalconX, IIIT Hyderabad, and several angel investors. Despite its efforts and initial successes, including plans to raise a $1 million seed round, Subtl.ai shut down in July 2025 after failing to secure further funding.
