The Challenges We Solve

We have worked across dozens of saas & b2b tools projects. These are the pain points we hear most, and know how to fix.

✗

Engineering bandwidth is a constant bottleneck for SaaS product velocity

✗

Multi-tenancy architecture done wrong creates data isolation bugs and security gaps

✗

Enterprise prospects demand SSO, audit logs, and compliance features your team has not built yet

✗

Subscription billing complexity, trials, discounts, usage-based pricing, breaks faster than it scales

✗

As you move upmarket, the engineering bar rises faster than your headcount can keep up

Our SaaS & B2B Tools Solutions

From product strategy to production deployment, our dedicated teams cover the full engineering lifecycle.

Multi-Tenant SaaS Architecture

Design and implementation of row-level security (RLS), schema-per-tenant, or database-per-tenant patterns, selected for your scale and isolation requirements. We also build tenant onboarding automation, configuration management, and self-serve upgrade flows.

Subscription Billing & Usage Metering

End-to-end billing integration with Stripe, Chargebee, or Paddle, including usage-based metering, dunning automation, trial management, and invoice generation. We build the billing layer to be your revenue engine, not an afterthought.

Enterprise Security & Compliance

SAML/OIDC SSO integration (Okta, Azure AD, Google Workspace), role-based access control (RBAC), audit logging, data export for GDPR compliance, and SOC 2 Type II-ready infrastructure posture.

Integrations & Platform Extensibility

Public API design, webhook systems, native integrations with Salesforce, HubSpot, Slack, and Zapier, and a developer portal for customer-built extensions. We help you become a platform, not just a product.

Frequently Asked Questions

How do you approach multi-tenancy architecture?▾

We evaluate your requirements across three dimensions: data isolation needs, performance at scale, and tenant-level customisation. Most B2B SaaS products we build use PostgreSQL RLS with schema separation for premium tenants. For highly regulated industries (fintech, healthcare), we use database-per-tenant isolation.

Can you take over and improve an existing SaaS codebase?▾

Yes. We regularly onboard onto existing SaaS codebases, conduct a technical audit in week one, and start delivering features by week two. We do not require a rewrite, we work within your stack and improve it incrementally.

How do you handle enterprise SSO integration requests?▾

We have implemented SAML 2.0 and OIDC integrations with Okta, Azure Active Directory, Google Workspace, PingFederate, and OneLogin. We treat SSO as a first-class feature and build it to support multiple IdPs simultaneously, essential when you have enterprise clients on different identity platforms.

What does a dedicated SaaS ODC team look like?▾

A typical SaaS ODC team is 4–8 engineers: full-stack developers, a backend specialist for API and billing infrastructure, a QA engineer running automated tests in CI, and a DevOps engineer managing infrastructure as code. You run the standup. We integrate into your sprint process.
