Guiding Growth With Insight
Thomas Waltair
Director
Neptune Financial Software Private Limited
India’s fintech story has always been driven by people who care deeply about solving real problems in banking, often long before the industry recognised the need. The growth we see today comes from leaders who learned through experience, adapted through uncertainty, and remained committed to building technology that genuinely serves people. Among them is Thomas Waltair, Director of Neptune Financial Software Private Limited, whose journey spans more than 17 years of shaping core banking systems with a calm, thoughtful, and hands-on approach. His earlier years at Covansys, Accenture, and Cordiant Technologies taught him the value of disciplined engineering and collaborative problem-solving, lessons that continue to guide his work at Neptune Software Group. A 150-member engineering team, Gartnerlisted platforms like Rubikon and Orbit-R, and 75+ successful banking deployments stand as milestones in a journey built on patience, persistence, and trust. TradeFlock spoke with him to understand the path behind these achievements, the challenges he overcame, and the vision leading him forward.
As Regional Director and Head of Group Product Engineering at Neptune Software Group, how do you ensure your technology stays ahead of policy changes while remaining fully compliant?
When you work in a space where regulations shift constantly, you quickly realise that waiting for policy updates is the fastest way to fall behind. At Neptune Software, I made it part of our product engineering mindset to stay ahead of changes before they ever hit our customers. That’s why policy readiness is built into our roadmap, especially in Rubikon, our Universal Core Banking System. By investing early in compliance automation, robust data governance, and configurable regulatory modules, we enable our clients to keep innovating without worrying about sudden rule changes slowing them down. For us, compliance isn’t a hurdle. It’s something that should clear the path for better ideas to move faster.
With fintech regulations constantly evolving, how do you plan long-term to stay ahead of competitors, and what challenges do you face in this process?
The fintech world changes faster than most industries, especially in payments, data localisation, and now AI ethics. Staying ahead means planning for a future that doesn’t yet exist, which is why we continue to invest in capabilities that can adapt—whether it is cloud, open banking APIs, or intelligent analytics. At the same time, working closely with central banks, ecosystem players, and our clients helps us shape solutions that address evolving regulatory needs. There are challenges, of course, especially balancing strict compliance with the agility the market expects. To address this, we built flexibility into Rubikon so it can scale and adapt without costly rework whenever the rules change. And if there is one belief that guides us here, it’s this:
"The future of fintech won’t be defined by predicting what changes next, but by building systems brave enough to evolve with whatever comes."
What leadership habits have helped you drive innovation at Neptune Software without compromising reliability or customer trust, and how have you strengthened stakeholder confidence along the way?
Over the years, I’ve learned that innovation only earns trust when people can see the thinking behind it. That’s why transparency sits at the heart of how my teams and I work at Neptune. Every feature and design decision has to strengthen reliability, resilience, and customer confidence, because those are the things that carry us through unpredictable moments. This approach pushed us to design for the unexpected and to hold a firm line on security, quality checks, and disciplined release governance. We involve our stakeholders early so they can grow with the product rather than react to it. That’s how we’ve moved into areas such as fraud detection, hyper-automation, and digitalfirst experiences without compromising the stability of core banking demands. Trust isn’t built through intent; it shows up in the consistency of what we deliver.
From a leadership standpoint, what challenges arise when expanding the organisation while staying agile and true to core values, and how does technology support you in this?
Growing across regions is exciting, but it can test the very identity of an organisation if you’re not careful. For me, the answer has always been to anchor every decision in the values that built Neptune in the first place. Staying agile becomes easier when teams work through DevSecOps and microservices, because it gives them room to experiment without losing synchronisation. At the same time, strong governance helps us maintain consistent standards wherever we operate, and a customer-focused engineering approach ensures we never lose sight of the real problems we are solving. Technology plays a big role, too. Rubikon’s modular design lets us expand without letting go of the reliability and agility that matter most in banking.
How are you shaping the next generation of leaders within Neptune Software Group to help the organisation scale sustainably across products, operations, and global support?
Scaling isn’t just about bigger teams or wider reach; it’s about growing people who can carry the organisation forward. At Neptune, we’re building that by mentoring product leaders to take full ownership of both their work and the outcomes it creates. We’re strengthening our expertise by setting up centres of excellence in AI, cybersecurity, and digital banking so teams gain depth in areas shaping the future. As more people become comfortable making decisions across global support and product lifecycle management, the organisation becomes more capable and confident. Our aim is simple: create leaders who don’t just maintain what exists today, but push the boundaries of what intelligent core banking can become.
