Mr O P Srivastava, Mr Ashish Srivastava's father, founded Chemtron Science Laboratories Private Limited. Mr O P Srivastava was a former BARC employee. Mr. O P Srivastava's visit to the United Kingdom while pursuing a government-sponsored PHD programme exposed him to the development of gas analyzers. He was astounded to discover that small businesses in the United Kingdom could make such high-quality goods. This sparked his curiosity, and he thought that he could do the same thing back in India.

Mr O P Srivastava pursued the idea during his free time at home because he had contractual duties with BARC. Mr. O P Srivastava created these items at his dining table. He was involved in trials for roughly 4-5 years.

Mr O P Srivastva formally began full-scale activities in 2000, after retiring from BARC. Mr. O P Srivastava obtained a loan and purchased a 600-square-meter plot of land in MIDC, Navi Mumbai.

Mr Ashish Srivastava was studying Engineering during the foundational phase of the business.. He  would spend a significant amount of time in the plant, assisting his father. He used to devote a considerable amount of time to research and development. During that phase, he successfully prototyped and designed a temperature control machine.

Many of his classmates moved to the United States and the United Kingdom to pursue their master's degrees after finishing their engineering degrees. Mr Ashish Srivastava was completely immersed in his work assisting his father at the time, and he was ecstatic about the things he was making.

Mr. Ashish Srivastava opted to stay back in India and began working full-time at Chemtron.

He had an extremely innovative mind and devoted himself entirely to product innovation.

Chemtron had won a project from Indian Oil Corporation, Mathura. They had to create & supply 4 nos of Gas Chromatograph systems. He worked 16 hours a day for days  with his father's ex-colleagues. This was  the career turning phase in the early days of his life.

Chemtron gradually expanded its product lines to include Gas Cylinders, engineering and electronics goods, and Specialty Gas Mixtures. Practically, they were the pioneers of the Galvanic Gas System. Mr Ashish Srivastava then headed the next stage of diversification, which included the production of gas regulators and gas analysers.

Mr Ashish Srivastava's father, Mr O P Srivastava, suffered a heart attack in 2009, and his doctors urged him to reduce his activities. He was 67 years old and this was his second attack.

Mr Ashish Srivastava got more responsibilities, including the commercial side of the company. He was 28 years old at the time. He began assembling the next level of leadership team. They began implementing processes and steadily progressed to the next stage of growth.

Mr Ashish Srivastava used a high bank leverage approach to build the business. For Mr Ashish Srivastava, servicing the debts was a positive presser. He didn't fear losing since he was an athlete, and he dreamed big. What drives him is the belief that money will eventually follow innovation and delivery.

Mr. Ashish Srivastava is working towards making Chemtron  a Rs 100 crore company by 2025.
