Deepank is the Founder of S45, an AI native investment bank focused on closing the capital markets gap for India's best emerging businesses. He works with founders who have built real, scalable companies and helps them access structured capital and public markets with clear, disciplined execution.He brings over 14 years of experience across investment banking, private equity, quick commerce, fintech, supply chain and actuarial sciences, with operating and investing roles at Blinkit, 1mg, BNP Paribas and Alcazar Capital. Before S45, he built a fintech platform that raised 5 million dollars in seed funding and grew into a meaningful wealth tech and structured finance business, which ultimately evolved into the S45 mission.Having scaled one of his ventures 10x to 60 million dollars in ARR, he has seen how strong fundamentals can still be held back by a lack of fit with traditional capital. Too operational for new age venture capital, too early for large institutions and unwilling to over dilute for private equity. Those constraints shaped his view on how capital should work for founders, not the other way around. At S45, his focus is on empowering 1,000 entrepreneurs over the next few years with the capital, strategic guidance and operating support they need to grow into India's next generation of resilient, high growth, blue chip companies.

Over his 22 year career, he has helped lead more than 16 main board IPOs, executed over 25 takeovers and managed rights issues, buybacks, mergers and demergers across multiple sectors. He has worked closely with some of East India's most prominent listed companies, including Ramkrishna Forgings, Rupa, Emami, Haldia Petrochemicals and Centuryply, guiding them through key phases of growth and market expansion. In his most recent role, Pankaj was part of the investor relations team at Shyam Metallics and Energy Limited, gaining firsthand insight into how large corporates think about strategy, capital allocation and sustained market performance. Having seen both the decisions that create lasting value and the missteps that hold companies back, he has built a strong track record in advising mid sized businesses on capital raising, M&A and long term value creation. At S45, he focuses on guiding founders through strategic growth initiatives, identifying acquisition opportunities and opening access to India's public markets.
