Among the many investments we consider, Syner-G differentiated itself as a founder-led company with an excellent reputation, outstanding capabilities, and experienced management. Riverside is looking forward to utilizing our deep healthcare and operational experience to help accelerate the Company’s growth.”

“We founded Syner-G with the goal of providing the highest quality science and risk-based CMC technical, regulatory and compliance consulting services and strategic advice to our customers,” said Prabu Nambiar, Founder and CEO of Syner-G. “When we decided to bring on a financial partner for Syner-G, we sought an investment firm with significant pharmaceutical services expertise, deep experience working with founder-owned companies, and a strong cultural fit with our Company. The partnership with Riverside will ensure that we can continue to deliver on this vision and enable us to continue to uphold our mission and support our customers.”

Binesh Prabhakar, Founder and Senior Vice President of Quality Assurance & Compliance of Syner-G, added, “In partnership with Riverside, we will continue to focus on meeting the needs of our customers and believe this investment not only allows us to better serve our existing clients but expands our ability to reach new customers and potentially offer other unmet services.
