Sunil Chandra Saha and Nitesh Singh founded Blue Tea in Kolkata in 2018 with ₹50,000 and one flower: the Butterfly Pea, or Aparajita. India's number one online herbal tea brand, Blue Tea now sells 50-plus flavours across 12 countries, reached ₹5 crore monthly revenue by March 2024, secured a deal with Aman Gupta on Shark Tank India Season 2, and serves passengers on Indigo Airlines.
Inspired by TVF Pitchers, Redirected by a Blue Flower
• Sunil Chandra Saha grew up in Chittaranjan, West Bengal, and built his corporate career at Aditya Birla Group, Bestseller Denmark, and Shoppers Stop before the entrepreneurial pull became too strong to resist. Nitesh Singh brought financial expertise to the partnership. Their inspiration was unconventional: the web series TVF Pitchers, which follows four friends who quit their jobs to build something of their own, spoke directly to both of them.
• Their first venture, a tech startup, struggled in 2018. But the research they did during that period led them somewhere unexpected. They discovered that butterfly pea flower tea was enormously popular across Southeast Asia and was starting to gain traction in the West. In India, the Aparajita flower grew abundantly, but no Indian brand had commercialised it into tea.
• The founders initially imported small quantities from Thailand to test market demand. The response was strong. They then made the decisive move to source locally, discovering that the butterfly pea flower thrived in Indian soil and that partnering directly with farmers could give them both quality control and a meaningful supply chain story.
• Under their company Redplum Private Limited, they named the brand simply: Blue Tea.
Go Global First, Then Win India
• The counterintuitive move that defined Blue Tea's early growth was going international before establishing India. When the brand launched, 80 percent of sales came from overseas markets in the US, UK, Canada, Germany, Australia, and France, while only 20 percent came from India. Rather than fighting for shelf space in a domestic market that did not yet understand flower-based herbal teas, they built credibility internationally first and then used that global recognition to earn trust at home.
• The product itself was the most powerful marketing tool. The Butterfly Pea flower brews a vivid blue colour in hot water and then transforms to purple when lemon is added, a dramatic, shareable, and entirely natural reaction that required no advertising budget to demonstrate. The teas are 100 percent caffeine-free, antioxidant-rich, and built on Ayurvedic principles that India had centuries of relationship with.
• The Shark Tank India Season 2 appearance accelerated everything. The founders asked for ₹75 lakh for 1 percent equity. After sharp negotiation, Aman Gupta invested ₹50 lakh for 3 percent equity plus ₹25 lakh in debt at 12 percent interest. Within 24 hours of the episode airing, Blue Tea's sales jumped 7X, and the Indian domestic market transformed from a secondary concern into the brand's fastest-growing segment.
Scale, Numbers and Real-World Impact
• Blue Tea reached ₹5 crore in monthly revenue by March 2024. D2C India sales grew from ₹3 lakh per month in March 2023 to ₹2 crore per month by March 2024, with the Indian market rising to represent 70 percent of total revenue. The brand serves over 1 lakh consumers monthly worldwide. Blue Tea ranks in the top 10 herbal tea brands on both Amazon.com and Amazon EU. It operates across 12 countries and offers 50-plus flavours in India and 35-plus in the United States. In September 2023, Blue Tea partnered with IndiGo Airlines, placing its teas on the 6E Eats menu for approximately 4 crore passengers per year. The brand works with 150 farmer families, predominantly women agriculturists, who earn five times more than traditional crops would provide. Blue Tea holds a 4.3-star customer rating across all platforms.
Sometimes the Biggest Opportunity Is the One That Has Been Overlooked in Your Own Backyard
• The sharpest lesson from Blue Tea's journey is this: the most valuable market insights are often hiding in plain sight, inside your own culture, your own soil, and your own heritage.
• The Butterfly Pea flower had been growing in India for centuries. Ayurveda had always known its properties. Southeast Asia had already built an entire herbal tradition around it. And yet no Indian brand had thought to put it in a box and call it tea.
• Sunil and Nitesh found the gap not in a global trend report but in a simple question: why is this flower everywhere in India, beloved in our own ancient system of wellness, and completely absent from our tea shelves?
• "BlueTea is envisioned to bring back the lost thousand years of glory, the ancient Ayurvedic flower teas, to your doorstep," Sunil Saha says.
• They started with ₹50,000 and a flower nobody was using. Today that flower serves crore passengers at 30,000 feet. The best opportunities are already around you.
