Meet the 13 Deeptech Startups Empowered by BIGShift Accelerator in India
India’s deeptech ecosystem has reached a significant milestone with the launch of BIGShift, a premier accelerator programme by Inc42 and India Accelerator designed to empower early-stage startups developing breakthrough technologies. The first cohort comprises 13 innovative startups addressing complex challenges in fields such as artificial intelligence, aerospace, robotics, healthcare, and geospatial analytics. These startups benefitted from specialized capital-readiness training, strategic mentorship, and direct access to investors interested in supporting high-risk, high-reward deeptech ventures, making BIGShift a crucial platform for nurturing India’s next-generation technology leaders.
The accelerator programme uniquely combines virtual bootcamp sessions with a comprehensive two-day in-person masterclass, equipping startups with advanced go-to-market strategies, funding expertise, and a valuable network of experienced operator-mentors. Noteworthy startups from the cohort include ActionSync, focused on enterprise data unification; Polygon Geospatial, delivering AI-powered real-time spatial analytics; Purna AI, which innovates in preventive health through genetic biomarkers; Spacetaxi, pursuing reusable commercial rockets; and VertiFly, specializing in hybrid eVTOL aerial mobility solutions. This diverse group exemplifies the ingenuity and pioneering spirit of Indian deeptech entrepreneurship across multiple high-impact sectors.
BIGShift’s inaugural cohort not only accelerates technological development but also provides critical support mechanisms like pilot project matchmaking, regulatory guidance, and facilitating enterprise collaborations. As these 13 startups transition their groundbreaking solutions from the lab to the marketplace, BIGShift is poised to be a catalyst for deeptech innovation in India, helping transform scientific research into scalable, impactful businesses that will shape the country’s technological future.
Chennai-based deep-tech startup Tan90 Thermal Solutions has raised INR 20 crore (about $2.3 million) in Series A funding, led by NABVENTURES, with participation from Blue Ashva Capital, Capital-A, and 3i Partners. The fresh capital will help Tan90 expand its energy-efficient cooling solutions across India and into Southeast Asia, the Middle East, and Africa.
Founded in 2019 by IIT alumni Soumalya Mukherjee, Rajnikant Rai, and Shiv Sharma, Tan90 develops innovative phase change materials (PCMs) that enable precise, sustainable cooling for sectors like food logistics, healthcare, and pharmaceuticals. Their technology covers temperatures from –50°C to +80°C, offering up to 40% energy savings and a significant reduction in carbon emissions.
Tan90’s Cooling-as-a-Service platform currently operates in eight Indian cities, serving clients like Swiggy Instamart and Kisaan Konnect, with plans to expand further. Recognized by organizations such as the Bureau of Energy Efficiency and UNIDO, Tan90 aims to make scalable, sustainable cooling infrastructure accessible to enterprises worldwide.
PayU India, owned by Prosus, has received final approval from the Reserve Bank of India (RBI) to operate as an online payment aggregator, a year after getting in-principle approval in April 2024. This authorization allows PayU to onboard new merchants and offer digital payment solutions, joining other major players like Razorpay, CCAvenue, and BillDesk.
The RBI’s nod comes as PayU prepares for its planned IPO in the second half of 2025, following a delay from its original 2024 timeline due to market conditions. The company, which serves over 450,000 merchants, reported $319 million in revenue from its core payments and credit business in the first half of FY25.
PayU stated that the approval will help it build a resilient, compliant, and innovation-driven institution, supporting merchants of all sizes and advancing the Digital India vision. The company has also strengthened its risk management and expanded its presence in real-time payments through a strategic stake in Mindgate Solutions.
Sarvam AI, the Bengaluru-based GenAI startup selected by the Indian government to develop the country’s first sovereign large language model (LLM), has launched Bulbul V2-a speech AI model supporting 11 Indian languages, including Hindi, Tamil, Telugu, Marathi, Bengali, Punjabi, and Odia.
Bulbul V2 stands out for its natural, regionally authentic accents, delivering speech that sounds genuinely Indian rather than robotic or rehearsed. The model offers ultra-fast performance with a P90 latency of just 0.398 seconds, significantly faster than global competitors like ElevenLabs, and is priced at ₹15 per 10,000 characters-five times cheaper than leading alternatives. Brands can also customize voices to create unique audio identities.
This launch reinforces Sarvam’s mission to make AI accessible and inclusive for India’s diverse population. Alongside Bulbul V2, Sarvam is building India’s first sovereign LLM under the IndiaAI Mission, focusing on secure, scalable, and multilingual AI solutions developed entirely within the country using local talent and infrastructure

Today, I went to the beachfront with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
