A well-designed developer platform is often dismissed as internal plumbing. But when it comes to the payments industry, where milliseconds matter, it may just be the foundation of a global-scale transaction engine.
Elastic, the company behind the popular Elasticsearch platform, is working on powering the essential infrastructure for financial services organisations, modernising their developer experience and data systems.
At the heart of this transformation is the intersection of intelligent search and grounded AI. While GenAI grabs headlines for its linguistic flair, financial companies are instead obsessed with accuracy, traceability, and compliance.
According to Karthik Rajaram, area VP & GM at Elastic India, that’s precisely where Elastic is stepping in, with a stack designed for real-time decision-making and developer-first tooling.
Developer Portals with Search Superpowers
Whether a developer is debugging a failed transaction, testing a new API, or grounding a GenAI model in regulated financial data, Elastic’s Search AI platform could be the increasingly unseen engine making it all possible.
Elastic’s work with a major financial services firm offers a clear view into what modern development looks like at scale.
“To ensure that developers have seamless, self-service access to tools and documentation, enabling them to innovate effectively, one of our customers, a large financial services company, developed their ‘Payments Developer Portal,’ which provides APIs, documentation, and sandbox environments,” Rajaram told AIM.
Elastic’s role was to power the search layer. By helping developers retrieve relevant information instantly from transaction records to system logs, it ensures they can debug payment issues, test new solutions, and ship features quickly.
He continued that the Elastic Search AI platform is a key part of the portal, equipping developers to efficiently find the data they need, a vital feature for working with complex payment systems and processes.
Furthermore, the collaboration between their platform and developers underscores the importance of robust search infrastructure in supporting large-scale, developer-driven innovation within complex financial ecosystems.
Real-Time Search in High-Stakes Payments
In today’s digital economy, payments are more than just fund transfers. They are expected to be instantaneous, secure, and fail-safe. The rise of payment apps has normalised this expectation, but the burden falls on backend teams to make it happen.
“That’s where Elastic’s capabilities become mission-critical. By pulling data in real-time, a payment can be made quickly, accurately, and logged to ensure compliance and reduce risks,” said Rajaram.
Elastic’s platform integrates deeply into customer payment systems, acting as the connective tissue that allows developers and operations teams to find anomalies, verify logs, and respond to threats in near real-time. It’s the invisible part of the payments stack, quietly ensuring uptime, trust, and regulatory traceability.
The broader goal isn’t just speed, it’s resilience. By making critical data accessible and queryable at all times, Elastic helps organisations maintain operational agility even as their systems grow in scale and complexity.
Grounding GenAI in Real Data
While ChatGPT-style AI may feel like a distant concern to payment engineers, Rajaram noted that generative AI is beginning to play a role in this space — particularly when grounded in real-time enterprise data. Elastic is doubling down on Retrieval Augmented Generation (RAG), combining LLMs with its search infrastructure to create more reliable AI outputs.
“Elastic’s scalable Search AI Platform retrieves information instantly, and when paired with retrieval augmented generation (RAG), large language models can ground their outputs in real-time business or financial data, reducing hallucinations and improving precision,” said Rajaram.
This is particularly valuable in financial services, where inaccurate answers could lead to failed compliance audits or reputational damage. RAG allows internal AI agents or copilots to access live data from Elastic’s index, ensuring every generated answer has an anchor in verifiable, secure records.
The approach also opens up new use cases, such as AI copilots for transaction support, fraud detection, or internal developer assistance, all built on top of an auditable and low-latency search layer.
Freedom of Choice
As the payments industry becomes more software-driven, Elastic’s core proposition is that search isn’t just a feature — it’s foundational infrastructure. As developers become central to business growth, offering them robust tools, accessible data, and AI-enabled capabilities is no longer a luxury.
The company’s dual focus, on enabling internal platforms like developer portals and on augmenting AI systems with trustworthy search, positions it well for the evolving needs of large-scale financial institutions.
Rajaram highlighted, “We also believe in empowering our developers with powerful starting points and choices.”
He continued, “Elastic provides several integrations with different cloud platforms and LLMs, and developers have the option to get started quickly with ready templates, or choose to build custom experiences regardless of the cloud environment or premises they are on, or the LLM they prefer to use.”
