Tech Meets Heart at the Right Time
Enter Sunfox Technologies, the brainchild of Rajat Jain, who took the stage on Shark Tank India Season 1 with a revolutionary idea: a portable ECG device that anyone can use, anywhere. This wasn’t just a business pitch — it was a mission to save lives using smart, scalable, and affordable technology.

Let’s explore how they went from a university lab in Dehradun to winning hearts (and money!) on national television.
The Brains Behind Sunfox Technologies: Rajat Jain
Rajat Jain, a biomedical engineering graduate from Graphic Era University in Dehradun, is no ordinary entrepreneur. He started Sunfox Technologies with the vision of building medical devices that could reach the grassroots level.
Early Challenges Faced:
- Lack of funding and hardware support in Tier-2 cities
- Convincing doctors to trust a compact, low-cost ECG device
- Battling the misconception that “cheap” equals “low-quality”
What Is Spandan? A Pocket-Sized Lifesaver
Spandan is a portable, pocket-sized ECG device that connects to your smartphone and provides clinical-grade ECG reports in under 30 seconds.
Key Features:

The Ask:
- ₹1 crore for 6% equity
The Pitch Focused On:
- Saving lives through early detection

- Tech + healthcare integration
The emotional appeal, backed by strong data and real-world impact, led to a moment that Shark Tank fans will never forget.

How Spandan Stands Out Among Competitors
Most portable ECG devices on the market:
- Are priced upwards of ₹25,000
- Require training to operate
- Don’t offer cloud syncing or real-time analytics
Spandan breaks the mold by being:
- Affordable
- User-friendly
- Compact and robust
- Clinically certified by ICMR and NABL labs
And yes, it’s made 100% in India — no dependency on foreign manufacturing.
