"In our EPC and electricals business, the biggest worry is whether a banker will truly understand how work actually gets done, but with S45 that clarity came immediately. They grasped our contracts, receivables, working-capital cycles and project timelines faster than anyone we've worked with, and the entire process felt structured..."

Deepank Bhandari

Founder

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.

Frequently Asked Questions

What is the due diligence process for IPO?

The IPO due diligence process typically starts with readiness assessment, data room setup, and a review of financial statements, governance, litigation, tax matters, related-party transactions, contracts, and material risks. From there, advisors coordinate evidence-backed disclosures for the DRHP, align management narratives with supporting documents, and prepare responses for legal, auditor, exchange, and SEBI review. The goal is a complete, defensible filing record.
