Build a SaaS Platform That Scales to Millions of Users
We architect and build the foundational layers your SaaS product needs: multi-tenancy, billing, onboarding, and the scalability patterns that support rapid growth without re-engineering every six months.
SaaS Engineering
- Multi-Tenant Architecture
- Billing & Subscriptions
- Feature Flags & Config
- Onboarding Flows
SaaS Architecture Foundations
A SaaS product is more than a web application. It requires specific architectural patterns to support multiple customers, isolate their data, and scale independently.
Get Started- Multi-tenant data isolation: shared schema vs. separate DB
- Tenant routing, sub-domain management, and white-labeling
- Feature flags and tenant-specific configuration
- Usage-based rate limiting and quota enforcement
- Horizontal scaling and autoscaling architecture
Billing & Subscription Infrastructure
Billing is one of the hardest parts of SaaS to get right. We integrate Stripe or Paddle with your product to handle subscriptions, usage metering, trials, and upgrades.
Get Started- Stripe Billing integration: subscriptions, trials, upgrades
- Usage-based billing with metering and overage handling
- Invoice generation, tax calculation, and dunning flows
- Self-service customer billing portal
- Revenue recognition and billing analytics dashboards
User Onboarding & Activation
The fastest path to revenue is getting users to their "aha moment" quickly. We build onboarding flows that activate users and reduce time-to-value.
Get Started- Guided product tours and interactive walkthroughs
- Progress tracking and activation milestones
- Welcome email sequences and in-app messaging
- Team invitation and role setup flows
- Onboarding analytics to identify drop-off points
Scaling for Growth
We engineer for the scale you don't have yet, so your architecture doesn't become the bottleneck when you hit your growth inflection point.
Get Started- Database sharding and read replica strategies
- Caching layers (Redis, CDN) for read-heavy workloads
- Background job queues for async processing
- Global CDN and multi-region deployment patterns
- Performance monitoring with automated scaling triggers
What We Deliver
A comprehensive set of SaaS Engineering capabilities, designed to work together or independently.
Multi-Tenant Architecture
Secure, scalable tenant isolation with shared or dedicated database strategies.
Billing & Subscriptions
Stripe integration for subscriptions, usage billing, trials, and self-service upgrades.
Feature Flags & Config
Feature flag systems for gradual rollouts, A/B testing, and per-tenant configuration.
Onboarding Flows
Guided onboarding, team setup, and activation flows that reduce time-to-value.
Product Analytics
Usage tracking, funnel analysis, and activation metrics to drive growth decisions.
Enterprise SSO & Compliance
SAML/OIDC SSO, audit logs, and data export features for enterprise customers.
Every SaaS product we build starts with the right multi-tenancy model for your customer profile.
Billing infrastructure is implemented from the start, not bolted on after launch.
Architecture designed to handle 10x your current user base without re-engineering.

Frequently Asked Questions
Common questions about our SaaS Engineering services.
Shared schema with tenant isolation (row-level security) is cost-efficient and simpler to operate for most B2B SaaS products. Separate databases per tenant are better when customers require strict data isolation for compliance — common in healthcare and finance. We'll recommend based on your customer profile and compliance requirements.
Yes. We often work with seed and Series A companies building their first SaaS platform. We help founders make the right architecture decisions early — avoiding the expensive rewrites that happen when the foundation isn't right.
Yes. Stripe Billing is powerful but complex — especially usage-based billing, trials with conversion, and dunning. We've implemented Stripe integrations across dozens of SaaS products and know where the edge cases are.
At minimum: auth (Clerk or Auth0), multi-tenant data model, Stripe subscriptions, and a basic onboarding flow. We can get this foundation live in 4–6 weeks, giving you something real to sell while we build the rest.
