Trusted By Industry Leaders to Build Complex, Scalable Platforms

Beyond a Website Builder: Architecting Your Digital Ecosystem
Building a platform like Squarespace isn't just about coding a drag-and-drop interface. It's about creating a scalable, secure, and feature-rich SaaS business that can compete in a crowded market. Many ventures fail because they underestimate the architectural complexity, the necessity for a robust multi-tenant infrastructure, and the ongoing demand for innovation. We help you navigate these challenges from day one.
Architectural Complexity
A true Squarespace competitor requires a sophisticated multi-tenant architecture, secure payment integrations, and a highly performant, real-time editing experience. We build the solid foundation your platform needs to scale without costly re-engineering.
Security & Scalability
Your platform will host thousands of businesses. We implement enterprise-grade security (SOC 2, ISO 27001 compliant) and build on cloud-native principles (AWS, Azure) to ensure your infrastructure can handle exponential growth securely and efficiently.
Competitive Differentiation
You can't out-Squarespace Squarespace. Success lies in targeting a specific niche. We help you strategize and build unique, AI-powered features—like automated design suggestions or industry-specific templates—that give you a powerful competitive edge.

Positive Outcomes
Case Study: Niche Website Builder for Photographers
Client Overview: A startup founder with deep industry knowledge in professional photography aimed to create a website builder specifically for photographers, featuring portfolio galleries, client proofing tools, and print-on-demand integration.
Problem: The founder needed a technology partner to quickly build a market-viable MVP to secure seed funding and validate the business model, without the massive overhead of hiring an in-house team.
Key Challenges:
- Building a high-performance image rendering engine.
- Integrating with third-party print labs and payment gateways.
- Creating an intuitive UI for non-technical, creative users.
- Delivering a scalable MVP within a tight, pre-seed budget.
Our Solution:
We deployed a dedicated POD (Product-Oriented Delivery) team that worked in 2-week sprints. We focused on a core feature set for the MVP, prioritizing the visual editor and client proofing workflow. Using a serverless architecture on AWS, we built a cost-effective and scalable foundation.
"CIS didn't just write code; they acted as our CTO. They challenged our assumptions and helped us focus on what truly mattered for the MVP. Their speed and expertise were instrumental in us securing our first round of funding." - Alex Royce, Founder of PhotoFolio
Positive Outcomes
Case Study: White-Label Platform for a Digital Marketing Agency
Client Overview: A mid-sized digital marketing agency wanted to offer website creation and hosting as a new, high-margin service to their clients, but was struggling with the inefficiencies of managing dozens of different WordPress sites.
Problem: They needed a centralized, multi-tenant platform that they could brand as their own, allowing them to rapidly build, deploy, and manage client websites at scale while maintaining consistent quality and security.
Key Challenges:
- Developing a secure multi-tenant architecture to isolate client data.
- Creating a customizable branding and theming engine.
- Building a centralized dashboard for the agency to manage all client sites.
- Ensuring high performance and reliability for hundreds of concurrent sites.
Our Solution:
We engineered a robust multi-tenant SaaS platform on Kubernetes for scalability and isolation. We built a "master admin" dashboard for the agency and a simplified, branded editor for their clients. The solution included integrated billing, allowing the agency to automate invoicing for their new service offering.
"The platform CIS built for us transformed our business. It created a new, predictable revenue stream and made our team incredibly efficient. We're no longer just a service provider; we're a technology platform for our clients." - Jenna Clay, COO of MarketMovers Inc.
Positive Outcomes
Case Study: Enterprise Website Builder for a Hosting Giant
Client Overview: A leading web hosting company wanted to compete with Squarespace and Wix by offering its own integrated, user-friendly website builder to its millions of customers.
Problem: The solution needed to be incredibly scalable to handle potentially millions of users. It also required deep integration with their existing infrastructure, billing systems, and domain management portals, all while meeting stringent enterprise security and performance standards.
Key Challenges:
- Architecting for massive scale and high availability.
- Complex API integrations with multiple legacy systems.
- Migrating user data and ensuring a smooth transition.
- Meeting strict security, data privacy, and performance SLAs.
Our Solution:
Working as an extension of their in-house engineering team, we co-architected a microservices-based platform. Our team took ownership of key modules, including the visual editor and the third-party app marketplace. We established a rigorous DevSecOps pipeline to ensure continuous integration and delivery while adhering to all compliance requirements.
"CIS's team brought the specialized expertise we needed to accelerate this critical project. Their understanding of large-scale systems and their commitment to quality were exceptional. They were true partners in this initiative." - Michael Harper, VP of Engineering at HostPlex
