SAAS

Develop, launch, and scale powerful Software-as-a-Service platforms with multi-tenant architectures and robust subscription ecosystems.

Strategic Intelligence

Empowering your infrastructure with SAAS architecture engineered for hyperscale.

The SAAS economy demands a unique blend of engineering speed and architectural robustness. At Cross City, we specialize in building multi-tenant platforms that are optimized for rapid iteration and mass scalability. We help tech founders and enterprise leaders turn software concepts into high-margin subscription products, handling everything from complex billing logic to secure user isolation. Our SAAS engineering framework is built upon a 'Compliance-First' foundation, ensuring that your platform is ready for global markets with GDPR, CCPA, and HIPAA standard capabilities integrated from the first line of code. We prioritize a frictionless onboarding experience for your end-users, using intelligent caching and edge-computing to deliver a snappy, native-app feel within the browser. Whether you are building an HR tool, a FinTech portal, or a niche CRM, we provide the full-stack infrastructure required to support your first 100 users or your first 100,000.

Knowledge Base

How do you ensure data security between customers?
We use 'Row-Level Security' (RLS) and strict tenant-ID isolation at the database layer. This ensures that it is mathematically impossible for one customer to access another's data, even in the event of an application error.
Can you help us build a mobile app version later?
Yes. By building your SAAS with an 'API-First' approach, we ensure that your backend can serve a web app, a mobile app, and even third-party integrations from the same secure data source.
What payment gateways do you recommend for global SAAS?
We generally recommend Stripe for its robust handling of recurring billing, tax compliance (Stripe Tax), and international support, but we can integrate any provider like PayPal, Paddle, or Adyen.
How do you handle sudden spikes in user activity?
We utilize serverless functions and auto-scaling groups that monitor CPU and memory usage in real-time. If a surge occurs, the infrastructure automatically spins up new instances to maintain performance.
Do you support Single Sign-On (SSO) for enterprise clients?
Absolutely. We can integrate SAML, OAuth2, and OpenID Connect to allow your corporate customers to log in using their existing systems like Okta, Azure AD, or Google Workspace.
How do you manage software updates across all tenants?
We use a 'Single-Codebase' approach. When we push an update, it is automatically deployed across the entire cluster, ensuring every customer is always on the latest, most secure version.
