Want to triple your loan portfolio growth over the next 2.5 years and launch products in just 8 weeks? You need a product engine. This short article outlines how to launch products quickly and successfully, what a product engine is, and why you don’t necessarily need to replace your current legacy core to achieve the growth you want.  

Only got five minutes? Here are the key takeaways of this article:  

• Launching your next growth project is easy when your current core is focused on run-the-bank activities while your product engine focuses on launching, operating and evolving products that bring in new growth and revenue, creating an easy path to fast growth without the stress of infrastructure risk.  

• You don’t need to overhaul your entire core to be able to access modern, technology-driven results such as achieving 648% portfolio growth in 12 months, 6.7x customer growth in 23 months, or 3x loan portfolio growth in 2 and a half years. You just need a product engine that runs alongside your current core, poised towards launching the products you want to the markets that excite you.  

• Control how your products evolve and tap into AI by shifting ownership of product cycles back to your internal team.  

• A product engine enables you to work using: 

• No code, which includes the ability to parameterise rates, fees, schedules, and eligibility in minutes without vendor tickets 

• Low code, which enables you to connect channels, payment rails, eKYC, and ecosystems in days using sub-100ms API response times 

• Your code, which lets you build proprietary, highly differentiated product logic through your product engine’s governed extension framework, accelerated by integrated AI tooling 

Build anything you want in just 60 days using the product engine framework. Book a call with vanda.jirasek@oradian.com to get your mini-core and accelerate your product launches.

Build anything you want, launch within months 

Digital banks, regulated financial institutions, and scaled consumer finance operators have been forced to play a zero-sum game when launching their next growth product. The traditional playbook has meant either waiting months for an incumbent core vendor to fulfil custom change tickets, building workarounds that end up creating engineering debt, or committing to a core banking replacement project just yet.  

Launching products quickly can bring in exceptional growth. In the Philippines, consumer loans covering credit cards, car finance and salary advances grew 19.6% year on year and card payments are forecast to almost double between 2024 and 2029. Meanwhile, in Indonesia, Bank Indonesia has just launched Kartu Kredit in August 2026, providing exciting domestic payment infrastructure the Indonesian market can tap into. 

The opportunity is immense. You don’t need to miss out on this next phase of growth.  

You don’t need to live like this.  

There is an answer. That answer is the product engine.  

With a product engine, your internal team can launch and change products without every change needing another project with your vendors. Product engines give you the autonomy to launch at your own pace, with your own team, without vendor restrictions using no code, low code, and your code.  

What is a product engine? 

A product engine is a lightweight layer of infrastructure that orchestrates the lifecycle, behaviour and rules of financial products, such as loans, revolving credit, or digital accounts, without requiring updates to your core legacy system. It essentially runs alongside your current infrastructure, which continues to focus on your standard operations, while the product engine is used by your team to launch entire product lines.  

It’s a little like using a mini-core operating system that runs alongside your current infrastructure. It enables your product, risk and operating teams to define, launch and adapt proposed products through customisable parameters instead of having to put together custom software builds. This means you don’t have to get tied into a huge company infrastructure overhaul just because you want to, let’s say, offer credit cards or digital accounts to your customers. Instead, you buy a product engine, like Oradian, turn it on, then it’s just a case of deciding what you want to launch and launching it. This can be done in just a matter of months, enabling you to jump on growth opportunities as they happen, rather than letting the competition get there first.  

Key benefits of a product engine 

Using the product engine framework brings several key benefits to your team:  

• Speed to market: Reduce the time it takes you to configure and launch new financial products, with some companies able to launch products within just a few weeks. Faster time to market means faster time to revenue.  

• Core augmentation: No one really wants to overhaul their entire infrastructure. Don’t get us wrong, the benefits of getting a modern core on revenue are extensive, but that doesn’t mean it's something you necessarily want to do this year. A product engine enables you to tap into the growth-enabling features of a modern core banking system without going through a core banking implementation. 

• Internal team autonomy: A product engine transfers control of product iterations away from third-party IT vendors and back into the hands of your internal teams.  

• Governed agility: With a product engine, you have the flexibility to test new pricing or distribution models while maintaining strict regional security and compliance oversight. A product engine is governed, versioned, auditable, reversibleand forward compatible, so your risk team gets control.  

• API connectivity: Real-time API layers enable you to connect external channels, KYC providers, payment rails and AI risk models directly into your new product lines.  

• Better decision-making: A modern product engine enables you to access AI agents today, which batch-processing reliant legacy providers cannot support. Agents can work on live data today, so limits, pricing and risk decisions respond to what customers are doing now.  

• Control: Ultimately, by using your own code, no-code frameworks, and APIs, your financial institution progressively controls everything from simple product parameters to ecosystem integrations.  

• Scalability: Growth is where cores tend to give way. A loan channelling business that takes off can push volumes through your core it was never sized for. A product engine carries that growth alongside your core, so success doesn’t break your infrastructure. 

Three product lines you could release in the next 60 days 

Using a product engine means taking away the technical debt and vendor dependency that usually stalls innovation. By running alongside your current core as a system of innovation, it gives your team the exact surface area needed to launch high-demand product lines.  

Loan channelling  

Co-lending and loan channelling require institutions to work with multiple originators and distribution channels. Each partner typically demands different product rules, pricing structures, fee split arrangements, limits, and reporting requirements. Trying to hardcode these variations into an incumbent core slows partner onboarding to a crawl. 

With a product engine, your product team sets up rates, fees, and rules in minutes without code, while your engineering team can use APIs to connect your partners directly to tailored loan products. You keep full control of your balance sheet and process high loan volumes without slowing down your core system. 

Credit cards and credit lines 

When regulatory shifts or new payment rails open up market demand, such as Indonesia’s domestic Kartu Kredit Indonesia initiative powering QRIS payments, beyond the rail, you still need an engine to manage credit facilities, dynamic limits, utilisation, pricing, interest accruals, drawdowns, repayments, and risk exposure to access this market growth opportunity.  

With a product engine, rather than waiting for your legacy vendor to build native support, you deploy the new credit proposition on the product engine layer. Bridging external payment processors, credit decisioning engines, and digital channels to your credit engine allows you to test, launch, and scale revolving credit lines quickly. 

Digital accounts 

Traditional banking cores weren’t built for millions of small, daily wallet transactions. Forcing high-frequency activity through your main system creates heavy load and drives up costs. 

By using a product engine, you can launch digital wallet accounts that process up to 12,000 balance updates per second in real time. Plus, your main core receives simple, consolidated daily summaries, keeping your primary system stable while giving users an instant wallet experience that boosts retention and attracts new customers. 

Oradian: Product engine X AI = Your 2027 growth strategy  

You can’t use AI when your operational data is trapped in legacy silos. 

This is why most AI projects in banking never make it out of the pilot. MIT’s Project NANDA, in its 2025 report The GenAI Divide, found that roughly 95% of enterprise generative AI pilots deliver zero measurable return, and the same research puts around 80% of the work needed to move a pilot into production down to data engineering, governance and workflow integration.  

The answer to gatekept AI is using a product engine.  

Your product engine runs the products. Above it, governed access to your operational data gives your teams a complete, current view of everything happening in those products, which they can query freely without putting load on the system serving customers. Above that sits your own code, running your own logic. AI works on top of all three, on live data, with a safe place for its decisions to take effect. 

Not to mention, with a product engine, you’re about to build using no code, low code, and your code, each of which centres control within your team, no matter what you’re working on.  

No code  

Parameterise rates, fees, schedules, and eligibility in minutes without vendor tickets.  

Low code 

Connect channels, payment rails, eKYC, and ecosystems in days using sub-100ms API response times. 

Your code 

Build proprietary, highly differentiated product logic through your product engine’s governed extension framework, accelerated by integrated AI tooling. 

With Oradian’s product engine, you get the foundation you need to work with AI without a core replacement. Oradian’s product engine runs at 99.98% uptime and handles 8,800 transactions per second, with 750+ native API endpoints that stay backwards compatible, so your integrations don’t break every time there’s a release. And before you commit to any of it, your engineers can prove the architecture and the performance for themselves in a sandbox that mirrors production.  

Oradian’s AI-native product engine gives you the ability to integrate AI agents to assist engineering teams in writing custom logic, authoring extensions, and generating API integrations, with some teams able to achieve all that in just hours. This drastically reduces the need for platform-specialised engineering resources and, of course, compresses your time-to-market. With Oradian’s product engine, real-time data flows directly from your engine into any risk or AI agents, so instead of relying on static credit limits or fixed interest rates, your products can automatically adjust credit availability and risk-based pricing based on live behaviour.
