Taking LegalTech SaaS to the Next Level with a Modern Front-End and API Architecture

Background

Founded by legal professionals specializing in supporting Microsoft-focused technology companies, Cloud Contracts 365 (CC365) began as an AI-powered non-disclosure agreement (NDA) review tool. After early traction and support from Innovate UK, the product evolved into a comprehensive contract lifecycle management (CLM) platform.

Award-winning and recognised for its innovation, CC365 is backed by accolades from TechNation, the British Legal Technology Awards (Innovation in Legal Services winner), the UK Business Tech Awards (finalist) and the Business Awards UK—underscoring its commitment to democratising legal services for tech businesses.

The company’s mission was clear: democratise legal services by making enterprise-grade contract management accessible to startups and SMEs. But delivering this vision required a scalable, reliable, and modern SaaS foundation—one that could support rapid innovation, seamless integration, and enterprise-level performance.

Challenge

The legacy platform, built on a monolithic .NET framework, was beginning to show its limits. Every deployment involved manual effort, updates were slow, and integration with other business systems required costly custom development.

As the user base expanded, scalability, performance, and data security became critical. The system couldn’t easily adapt to new compliance frameworks or integrate cleanly with enterprise APIs like SharePoint, Dynamics, or Teams.

To sustain growth and serve larger enterprise customers, Cloud Contracts 365 needed a cloud-native, API-first architecture — enabling faster releases, real-time connectivity, and improved reliability across a multi-tenant SaaS environment.

Solution

Uptic deployed a Product & Platform Team to re-engineer Cloud Contracts 365 into a cloud-native Azure SaaS platform, combining deep architectural expertise with modern UX and agile delivery practices.

• API-First Architecture: Rebuilt backend services as modular microservices with RESTful APIs, simplifying integrations with Microsoft 365 and third-party legal tools.
• Modern Front-End: Delivered a responsive React-based interface with reusable components and improved accessibility for legal users.
• Automated CI/CD: Introduced fully automated pipelines with testing, quality gates, and rollback protection to accelerate safe releases.
• Infrastructure-as-Code (Terraform): Standardized environments for consistent, repeatable deployments.
• Scalable Azure Infrastructure: Leveraged Azure App Services and Kubernetes for elastic scaling and high performance.

Uptic’s fractional delivery model — UI/UX designers, full-stack developers, testers, and SREs rolling on and off as needed — ensured delivery stayed lean, fast, and aligned to business outcomes.

Outcomes

The modernization transformed a static, costly legacy system into a high-performance, cloud-native platform — dramatically improving efficiency, scalability, and sustainability.

• Faster delivery: Release cycles shortened from quarterly to bi-weekly.
• Improved performance: API latency reduced by 60%, enhancing user experience.
• Cost efficiency: Azure optimization and automation cut infrastructure spend by 40%.
• Security and compliance: Architecture aligned with ISO 27001 and GDPR standards.
• Scalable foundation: Future-ready design supports AI-driven contract analytics and new SaaS modules.

“Uptic’s ability to modernize our platform while keeping us fully operational was impressive. The new architecture has given us speed, control, and confidence as we scale.”_{- Product Director, Cloud Contracts 365}
