From the Ground Up: The Growth of Convergent Science India

In 2017, Convergent Science expanded to Pune, India, welcoming Ashish Joshi as the founding leader of our new office. Back then, the office was a quiet hub of possibility with plenty of open desks, a one-person team, and the excitement of building something new. We wrote a blog post back then, documenting the early days and the potential the office held. Fast forward eight years, and the office has become a bustling environment, filled with new ideas, forward-thinking people, and dynamic energy. Convergent Science India LLP has grown in not just size, but also spirit as we welcomed new colleagues, took on interesting projects, and worked to build a collaborative culture. But you know the ending, so let’s start at the beginning.

The initial purpose of the India office was to capture the internal combustion engine (ICE) CFD market in the Indian region. The India office was born in “Supreme HQ,” an office space with a maximum capacity of 12 employees. In August 2017, Ashish welcomed his first teammate, Kamlesh Patel.

“Being the first employee at Convergent Science India wasn’t just about joining early—it was about helping shape the foundation of something lasting,” says Kamlesh. “From navigating new challenges and giving training courses to growing alongside brilliant minds and forming lifelong friendships—this journey has been deeply personal and incredibly fulfilling. I’m proud of how far we’ve come, grateful for the people who made it possible, and excited for everything still to come.”

The two became the core of our Indian operations, with Kamlesh focusing primarily on ICE support. Soon after, Harshan Arumugam joined the team to explore how CONVERGE could break into new application areas beyond engines.

Like any start-up organization, the early days of Convergent Science India were riddled with challenges. Even small administrative tasks like opening company bank accounts or accounting for tax compliance were immense hurdles for the three-person team. Not to mention, CONVERGE awareness in India was minimal at the time, so the team had to educate the market while simultaneously training new engineers and building brand credibility.

As operations stabilized, the vision expanded. The team began exploring markets in neighboring Southeast Asia, carrying the CONVERGE message beyond India and across international waters. A major milestone was the successful organization of the first CONVERGE User Conference in the region in 2019. Strong support from the world headquarters played a crucial role in strengthening the company’s reputation and boosting the credibility of the India office. Through this newfound visibility, the India team was able to exert broader regional influence, quickly pulling in new CONVERGE customers.

About a year or so in, Ashish proposed a novel idea: to expand the India office to include functions outside of technical support. The leadership team in Madison approved, and soon, the team began looking to fill roles in Marketing, Documentation, Testing & Validation, Development, and more. By and by, the India office evolved from a small service branch to a full-fledged contributor to Convergent Science’s global operations.

It wasn’t long before our expansion efforts started to show. By 2025, Convergent Science India has become a diverse, cross-functional powerhouse, whose headcount of 36 employees is a powerful marker of how far we’ve come.

“Being not only the newest but also the youngest employee, I feel excited to be working here and learning about CFD. As my first full time position after college, I had no idea what to expect, but I felt both welcomed and challenged,” says Rohit Kamath, the office’s newest hire. “The environment is lively and everyone is so knowledgeable and approachable. Not to mention, the office events, like diya painting or pottery workshops, keep our day-to-day life fresh and exciting. I’m grateful for the sense of community I’ve found here. Whether it’s lunch breaks to the nearby coffee shop for the best 35 ₹ ($0.40) cup of coffee or working on new marketing applications, there’s always something new to learn and grow from.”

As new hires poured in, the original Supreme HQ office space started filling up, proof that our ambitions were quickly outgrowing our humble beginnings. As such, we moved to a larger space at IndiQube Unity Tower. The new office provided more room for our rapidly expanding team. After overseeing the move to the new office building and getting things established there, Ashish moved to the U.S. to pursue a different role within the company. He passed the managerial reins to Yajuvendra Shekhawat (Yaju), who is now the India office’s general manager.

Under Yaju’s guidance, the India team has made inroads into application areas beyond ICEs, although they remain the largest component of our market in the Indian region. Turbomachinery is an emerging focus, and the office has also had success in the oil and gas industry. Simultaneously, the team has been actively encouraging existing clients to use CONVERGE for applications beyond ICEs, broadening our solver’s foothold in R&D environments. The office has also built strong relationships with leading academic institutions, particularly across the IIT system. Many of these prestigious institutions now use CONVERGE for a wide variety of research applications. On the industrial front, the office also works with most of the major automotive companies in India that are engaged in IC engine R&D.

With the current office at IndiQube Unity Tower now nearing capacity, Yaju and his team are actively exploring options for the next phase of expansion. For now, there’s still room to grow, and a lease renewal is under consideration for September 2025. As the team continues to expand in both size and scope, it’s clear that the India office will remain a vital part of Convergent Science’s global operations.

“In 2017, I joined Convergent Science India, fresh out of university with a passion for internal combustion engines,” says Kamlesh. “Ironically, my first interaction with Ashish was a polite rejection for an internship at CS India due to limited resources. Life clearly had other plans. From a two-person team to a thriving office of nearly 40, I’ve had the privilege of growing with CS India from day one. Early on, I was delivering training courses to customers and universities, a challenge that pushed me out of my comfort zone and helped me grow. What makes CS India truly special is the people. From cricket and coffee to road trips and other milestones, we’ve built friendships that go far beyond work. A huge thanks to Ashish for setting the tone and Yaju for continuing to lead with empathy, integrity, and vision. They, along with our global leadership, have given all of us the freedom to grow, explore, and evolve not just as engineers, but as people.”

Kamlesh’s words are indicative of the India office’s vibrant and inclusive culture. The team understands that productivity isn’t just about working hard behind a screen; it can also look like birthday celebrations in the office, outdoor cricket games, and company walks to the nearest convenience store for coffee or other delightful snacks. As we look ahead to the near future, we’re excited to keep expanding, evolving, and writing the next chapter of our office’s story together.
