This isn’t just a story told through numbers—it’s a journey of impact, of two visionaries who dared to dream big and of a team that brings that dream to life every day for clients across India, the U.S., Europe, Asia-Pacific, Canada, Australia and beyond.
This is Mercurius: a name built on resilience, trust and relentless commitment.
From modest roots to a global presence
In 2008, Ankit Jain and Siddhartha Havelia chose courage over comfort. Leaving behind secure roles at renowned firms like PwC, American Express and Grant Thornton, they stepped into the unknown—armed only with experience, conviction and a shared vision to make finance more meaningful.
They began with the basics—conducting physical verification of assets from a small, no-frills office. No glossy presentations. No big promises. Just one guiding principle: “Let your work speak for you.”
And it did.
One client led to ten, ten to a hundred. Every project completed, every challenge overcome, built something more than a portfolio—it built trust. And that trust became the true currency of Mercurius—earned with integrity, sustained by impact.
Mercurius: More than just a name
Today, Mercurius stands for more than what’s printed on a letterhead—it’s a symbol of integrity, excellence and partnerships that transcend borders. With a team of over 400 professionals and clients across more than 60 countries—from India to the U.S., Singapore to the UAE, Australia to the U.K.—Mercurius is both a financial ally and a trusted guide through the ever-evolving complexities of global business.
Their work goes far beyond routine compliance. From helping startups expand into new jurisdictions, to conducting rigorous audits, to driving growth with strategic tax advisory, Mercurius empowers businesses at every stage. The firm navigates US GAAP, IFRS, ESG mandates, SPAC structures and cross-border tax landscapes with precision.
Their Global Capacity Centres (GCCs) offer clients a reliable platform to delegate essential accounting and compliance functions, ensuring accuracy, efficiency and adherence to the highest professional standards.
But while others chase numbers, Mercurius stays focused on impact. Its global expansion—from North America to Europe, Asia-Pacific to the Middle East—isn’t just about presence; it’s about reshaping the future of finance. By integrating AI-powered tools and staying ahead of emerging trends, the team ensures clients receive smarter, faster and more agile solutions in a rapidly shifting world.
The people behind the purpose
What truly sets Mercurius apart isn’t a slick tagline or aggressive marketing—it’s the people. A team of professionals who lead with integrity, think proactively and bring both insight and initiative to every client interaction.
At the helm are 12 partners, including co-founders Ankit Jain and Siddhartha Havelia—seasoned leaders with deep roots in accounting and finance, each bringing a unique strength to the firm’s foundation and growth.
Ankit Jain is known for his precision and strategic mindset, especially in audit, taxation and valuations. His leadership has been instrumental in driving Mercurius’ global expansion and steering its long-term vision.
Siddhartha Havelia, with his technical expertise in valuations and process transformation, champions innovation while nurturing a people-first culture, where collaboration, learning and growth are more than just values; they’re daily practice.
At Mercurius, people don’t just perform tasks—they build careers, shape purpose and help clients create enduring legacies.
Solving for growth: How Mercurius helps businesses break through
