Accelerating SME Banking Transformation in Asia Pacific
Modernizing for growth in a market that cannot wait
Across Asia Pacific, banks serving small and medium-sized enterprises are under pressure from every direction. SMEs are central to economic growth across the region, yet many remain underserved by traditional banking models. At the same time, digital-first challengers are reshaping expectations, regulatory requirements vary significantly market by market, and legacy technology continues to slow change at the very moment speed matters most.
For incumbent banks, this is no longer just a modernization agenda. It is a growth, relevance and inclusion agenda. The institutions that can launch and refine SME propositions quickly, safely and locally will be best positioned to win.
Publicis Sapient and Tuum help banks do exactly that. Together, we enable financial institutions to move away from rigid legacy cores and toward modular, cloud-native architectures that support faster product launches, lower maintenance spending and more adaptable service models for diverse APAC markets.
Why SME banking transformation is especially urgent in APAC
Asia Pacific presents a uniquely complex opportunity. The region combines high digital adoption with fragmented regulation, fast-evolving customer expectations and strong competitive pressure from fintechs and emerging digital banks. For banks with large legacy estates, that creates a difficult balancing act: they must innovate faster without increasing operational risk or losing control of compliance.
SME clients feel this tension directly. They increasingly expect intuitive onboarding, connected account experiences, better access to data and more responsive services that fit the way they run their businesses. Yet many traditional banking environments were not designed to deliver these capabilities quickly. Product development can be slow, integrations can be costly and market-specific tailoring can become difficult to scale.
This is where a composable approach changes the equation. Instead of relying on one monolithic transformation effort, banks can prioritize the areas that matter most, modernize in stages and create a technical foundation that supports continuous evolution.
A modular model built for regional complexity
Publicis Sapient and Tuum bring together strategy, experience design and engineering with a modular core banking platform built for flexibility. Tuum’s platform allows banks to choose the transformation areas they want to focus on, helping reduce both development time and cost. Publicis Sapient then helps turn that flexibility into a practical transformation program—one designed around business goals, customer needs and the realities of delivery in regulated environments.
For APAC banks, that model offers several clear advantages:
- Faster time to market: Launch new SME propositions and digital services more quickly by modernizing the capabilities that matter most first.
- Lower maintenance burden: Reduce dependence on outdated legacy systems and redirect investment toward growth and innovation.
- Composable architecture: Build a solution landscape that can evolve incrementally instead of forcing a single, disruptive overhaul.
- Market-by-market adaptability: Tailor products, journeys and operating models to local regulatory and customer requirements without rebuilding everything from scratch.
- Better data accessibility: Create the conditions for improved decision-making, connected experiences and future AI-enabled services.
The result is not just a new platform. It is a more adaptive banking operating model—one that helps banks serve SMEs with greater precision, speed and confidence.
From core modernization to customer-centric SME experiences
Technology modernization only creates value when it improves what banks can deliver to customers. That is why Publicis Sapient approaches transformation through both the business and customer lens. We help banks rethink not just systems, but also journeys, propositions and the operating model behind them.
In SME banking, this can mean creating connected experiences across account types, streamlining onboarding, improving access to payments and real-time information, and making it easier for business customers to manage finances in one place. It can also mean building new digital products and services with a roadmap that supports long-term efficiency and cost-to-income goals.
Because composable banking makes it easier to assemble and extend capabilities, banks can respond more effectively to changing market conditions and evolving SME expectations. They can test, learn and launch with greater control—without destabilizing critical systems or compromising service quality.
Proven regional delivery in Thailand and Southeast Asia
Publicis Sapient’s experience in APAC shows that speed and control do not have to be trade-offs. In Thailand, we helped a leading retail bank transform more than its front end. The client wanted a new business model and a stronger technical foundation to support future growth. Working with a multidisciplinary team across strategy, UX, creative and engineering, we helped deliver a front-to-back banking platform in just 12 weeks.
The transformation connected the mobile app, payment platform and a real-time data lake, creating a customer-first foundation that allowed the bank to move faster, adapt to changing expectations and bring new products and services to market at speed. Just as importantly, the work demonstrated that banks can innovate quickly while still adhering to strict internal policies and external regulatory obligations.
That experience matters in Asia Pacific, where banks often need to accelerate delivery without losing governance. It also reinforces Publicis Sapient’s ability to combine rapid deployment with customer-centric design, modern engineering and disciplined execution.
What APAC banks can unlock with Publicis Sapient and Tuum
For banks looking to strengthen their SME position in Asia Pacific, modernization is an opportunity to do more than replace aging technology. It is a chance to build a more resilient, responsive and differentiated business.
With Publicis Sapient and Tuum, banks can:
- Modernize legacy cores through modular, cloud-native architecture

- Improve cost efficiency by reducing maintenance spend on outdated systems
- Increase flexibility to serve multiple markets with greater local relevance
- Create customer-centric experiences grounded in accessible data and composable services
- Build a roadmap for continuous innovation rather than one-time change
Build the next era of SME banking in APAC
The competitive reality in Asia Pacific is clear: banks must move faster, modernize smarter and deliver experiences that reflect the needs of today’s SMEs. Legacy systems make that difficult. Composable, cloud-native banking makes it possible.
Publicis Sapient and Tuum help banks turn transformation into action—modernizing the core, unlocking data, accelerating delivery and creating customer-centric propositions that can scale across complex regional markets.
For APAC institutions, the opportunity is not simply to keep pace with change. It is to lead with services that are more agile, more efficient and better aligned to the businesses driving the region forward.
