Siddhant Dangi and Deepansh Goyal, final year engineering students at Birla Institute of Technology and Science (BITS) Pilani, have turned entrepreneurs by launching a technology startup that can help understand the thoughts of a human mind.

Siddhant had watched a TED talk video by Greg Gage, who demonstrated the ability to control a cockroach by sending electrical impulses to its antennas. This enthused him and Deepansh to work tirelessly on a project that could lead to better interface between human beings and machines.

The budding entrepreneurs strongly believe that unlike the human body, the human brain has no limits. With advancements in technologies such as artificial intelligence (AI) and machine learning (ML), there is better understanding on the pattern of human thoughts and how devices around us can be controlled by the mind.

Siddhant and Deepansh went about their mission to build a technology platform where the signals from the human brain could be collected, processed, and analysed to determine the pattern of thoughts.

At the core of this is electroencephalography (EEG), which is used to capture or monitor the brains electrical signals. EEG technologies have been available but it is only now that there is greater accuracy, thanks to AI and ML.

Nexstem has developed hardware and software capabilities to read electrical signals from the human brain more accurately.

It has created a headgear that captures electrical impulses of the brain and transmits them to its software platform, which analyses the data. Siddhant mentions that the cheapest EEG device that captures these signals costs around Rs 80,000.

The duo took part in various competitions and won several cash grants, including Rs 10 lakh from a leading MNC. They invested all the money into product development.

The founders of Nexstem have developed a sophisticated signal processing technology and machine learning algorithms that can capture and understand the electrical impulses in the mind to give better insights into what a person is thinking.

According to Siddhant, their signal processing and prediction technology works flawlessly, blocking all the external noise to give clean data.

The technology developed by the two young students can find applications in various sectors like healthcare, smart homes, and robotics. It can help develop a more effective bionic arm, allowing human thoughts to ensure better co-ordination with the body.

Deepansh is very clear that they will not focus on a single product or device; the founders want to create a platform that can find multiple applications. The startup aims to help companies integrate their software platform with their devices.

There is still work to be done as Nexstem's software development kit is yet to be opened to the public. The founders plan to launch it in the next four to six months.

There will be protocols on how to use their software technology platform in terms of code, controls, and functions available.

The strides made by Nexstem have already evinced interest from the investor community and technology companies. It has received funding from HostelFund, a platform that helps student entrepreneurs, and also from BITS Spark Angels, a group of angel investors who are BITS Pilani alumni.

The founders say they will reach out to individuals who can make immense value addition to the startup, in terms of technology and market access.

Siddhant and Deepansh received ample support from their institute too. Despite being sceptical about their venture initially, BITS Pilani has been very supportive.

Both the founders have kept themselves mostly free from academics to focus on their startup. They overloaded their courses in their previous semesters.

Siddhant and Deepansh will be graduating in May next year but envision their journey with the startup for the next four years. They plan to create a base in Gurugram and will target the US and India markets with their technology platform and devices.
