SaaS built to acquire, retain, and scale
Multi-tenant architecture, subscription billing, role-based access, analytics, API. We engineer SaaS products that do not need to be rebuilt when you hit growth.
Free call. We'll map your architecture and flag the expensive mistakes early.
Every layer of a modern SaaS product
From database schema to the dashboard your customers log into every day.
Multi-tenant architecture
Shared database with row-level security or separate schemas per tenant. We pick the isolation model that fits your compliance needs and expected scale.
- Row-level security or schema-per-tenant — chosen based on your data sensitivity requirements and tenant count projections
- Scales to thousands of tenants without schema changes — designed upfront so you never need to migrate mid-growth
- GDPR and SOC 2 compatible isolation options — data never leaks between tenants by design, not just by convention
- Tenant provisioning automated — new customer signs up, their environment is ready without manual setup
Subscription billing
Stripe integration: products, prices, trials, proration, dunning, the billing portal. The edge cases get handled, not deferred to version two.
- Stripe or Paddle integrated fully — subscription creation, upgrades, downgrades, pauses — all handled
- Usage-based pricing if needed — metered billing, seat limits, feature gating tied to plan level
- Dunning and failed payment recovery — automatic retry logic, customer emails, churn prevention flows
- Customer billing portal included — self-serve plan changes, invoice download, card updates without contacting support
Auth and permissions
SSO, role-based access, team management, audit logs. Built on proven providers rather than custom crypto that will need replacing later.
- SSO via SAML and OAuth 2.0 — Google, Microsoft, Okta, and custom identity providers
- Role-based access with granular permissions — per-resource, per-action — not just admin/user
- Team management and invitations — member adds/removes, pending invites, role assignment by admins
- Full audit log of authentication events — who logged in, from where, what they changed — for compliance
Product analytics
Event tracking, funnel analysis, retention metrics. You understand what users actually do instead of what you hope they do.
- Event tracking from day one — every meaningful user action tracked before the first customer logs in
- Funnel and retention analysis — where users drop off, which features drive retention, which drive churn
- Amplitude, Mixpanel, or PostHog integration — or custom analytics if your data cannot leave your infrastructure
- Feature flags for controlled rollouts — release to 10% of users, measure impact, then roll out to everyone
Public API and webhooks
Lets your customers integrate. API keys, rate limiting, webhook delivery with retry logic, developer documentation that does not require a support ticket to use.
- REST or GraphQL API, documented from day one — OpenAPI spec generated automatically, Postman collection included
- API key management and rate limiting — per-key limits, usage dashboards, key rotation without downtime
- Webhook delivery with retry logic — failed deliveries retried with exponential backoff, delivery log available
- Developer documentation that actually works — code samples in multiple languages, sandbox environment, changelog
Admin and ops panel
Manage accounts, override plans, investigate issues, impersonate users safely. The internal tool your team will use every day from day one.
- Account management and plan overrides — support team can upgrade, downgrade, extend trials without touching the database
- User impersonation with full audit trail — debug customer issues as them, every session logged for accountability
- Usage metrics and health dashboard — MRR, churn, active users, error rates — in one internal view
- Customisable for your support workflow — built around how your ops team actually works, not a generic admin panel
How we build SaaS products
- 01
Architecture session
Tenant model, data isolation strategy, billing logic, integration surface area. Decisions made upfront here save months of rework later.
- 02
Core infrastructure
Auth, billing, multi-tenancy, CI/CD pipeline. The foundation before features. Skipping this is why SaaS products end up needing rewrites.
- 03
Feature sprints
Two-week cycles with live demos. Scope adjusts as you learn from early users rather than following a plan written before anyone signed up.
- 04
Beta and feedback
Controlled rollout to first customers, feedback collection, rapid iteration. Real usage reveals things no amount of internal testing does.
- 05
Launch and growth
GA release, monitoring, performance work, and whatever growth-oriented features the data says to build next.
Common questions
How is SaaS different from a regular web app?
Multi-tenancy, billing infrastructure, compliance requirements, and architecture designed for growth make it significantly more complex. Scoping for this from the start is cheaper than retrofitting it later.
Do you handle Stripe integration?
Yes. Products, prices, subscriptions, trials, proration, failed payment handling, dunning, and the customer billing portal.
What database do you use?
PostgreSQL as the default for most SaaS products. MySQL and MongoDB where there are existing technical reasons that make sense.
Can a mobile app be added later?
Yes. We design APIs to be consumed by mobile clients from the start, so adding one later is an extension rather than a rearchitecture.
What does a SaaS build cost?
A focused MVP with billing, auth, and core feature loop starts from €25,000–45,000. A full SaaS with API, admin panel, and analytics is typically €60,000–120,000 depending on scope.
