In today’s financial landscape, core banking systems are expected to do more than just “work.” They need to adapt, innovate, and scale—all without breaking the bank or the back office. Unfortunately, many institutions are still burdened with legacy systems that are rigid, siloed, and expensive to maintain.
At Craft Silicon, we’ve been listening to our clients. From tier-one banks looking to modernize, to microfinance institutions expanding across borders, the message is clear: “We need a smarter, faster, and more flexible core.”
That’s exactly why we built Nimble.
The Problem: Legacy Systems Are Slowing Financial Growth
Across Africa and Asia, financial institutions are facing a common challenge: scaling up digital capabilities while managing outdated core systems. Some of the issues our clients faced before Nimble include:
- Long product rollout cycles due to hardcoded configurations
- Limited integration capabilities with fintechs, wallets, or digital lending platforms
- High infrastructure costs and slow system performance during peak hours
- Difficulty complying with evolving regulatory requirements in real time
These pain points don’t just affect operations—they delay innovation and impact customer satisfaction.
The Solution: Nimble, A Core Built for Change
Nimble is our response to these challenges: a cloud-native, API-first, modular core banking system that puts flexibility and speed at the center.
We’ve already seen transformative results with early adopters across Kenya, Tanzania, and South Asia:
- Reduced product launch time from months to weeks
- Seamless integration with mobile money, agent banking, and wallet services
- Real-time transaction processing with no downtimes
- Instant compliance updates tailored to local regulatory environments
Why It Works: Nimble in Action
Nimble works because it was built from the ground up to solve real-world banking problems:
- Product Agility: Launch, modify, or sunset banking products with no code-heavy deployments
- Open Integration: Connect to any fintech partner via open APIs—no vendor lock-in
- Multi-Channel Ready: Supports mobile, branch, agent, and digital banking seamlessly
- Secure by Design: Includes fraud detection, role-based access, and biometric authentication layers
This means banks and MFIs don’t need to spend years overhauling their tech stack. They can modernize step by step—at their own pace, with full support from us.
It’s Not Just Technology. It’s Partnership.
At Craft Silicon, we don’t just drop in software and walk away. Our success is tied to our clients’ success.
With Nimble, we offer:
- Tailored implementation strategies based on your current system and goals
- Hands-on training and support for your operations, tech, and compliance teams
- Scalable modules to grow with your institution’s ambitions
We’ve made it our mission to democratize modern core banking, not just for the big players—but for every financial institution ready to lead the digital era.
Your Core Shouldn’t Hold You Back. It Should Drive You Forward.
The future of banking belongs to institutions that can move fast, launch smarter, and serve better. Nimble is here to make that future accessible.
