SaaS development
A studio service
Built for retention, not just launch.
SaaS products designed around the metrics that matter: activation, expansion, and churn. Multi-tenant architecture, Stripe billing, and growth loops designed before a line of code is written.
N° 01SaaS-specific challenges
Multi-tenant. Built to retain
SaaS products have a specific failure mode that consumer apps don't: churn. A product that acquires users and fails to retain them is a leaking bucket — it can never grow faster than it shrinks. We build for retention from the first architectural decision.
Multi-tenant architecture, subscription billing, onboarding flows, usage metering, and the growth loops that move users from free to paid are all first-class concerns in a SaaS build. Not features added later — foundations designed in from the start.
N° 02SaaS architecture
The infrastructure that scales
01
Multi-Tenancy
Row-level tenant isolation in a shared database, or schema-per-tenant for regulated industries. Tenant-aware querying, middleware, and the access control layer that prevents data bleed.
02
Subscription Billing
Stripe Billing or Paddle integration: plans, trials, seats, metered usage, proration, dunning, and the invoice lifecycle that keeps revenue operations sane.
03
Auth & Permissions
Email/password, OAuth (Google, GitHub, Microsoft), SAML SSO for enterprise tiers, and role-based permissions that scale from a solo user to a 500-seat account.
04
Usage & Analytics
Event tracking, feature flags, usage metering, and the admin analytics that tell you which features drive retention and which drive churn.
N° 03Growth loops
Acquisition built into the product
The best SaaS growth comes from product behaviour: virality loops, referral mechanics, and the activation milestones that predict whether a new user will still be a user in month three.
We map activation milestones and engagement events in discovery — before the UX is designed. Onboarding flows, empty states, and feature discovery are all designed against the data that predicts retention.
Product-led growth (PLG) architecture: free tier logic, upgrade prompts triggered by behaviour not time, and the billing integration that makes the moment of conversion frictionless.
N° 04Admin tooling
Operate it without an engineer
A SaaS product without operator tooling is one where every customer issue requires an engineer. We build the admin panel alongside the product: account management, feature flag controls, impersonation, billing overrides, and the event log that tells support what happened.
We also build the internal analytics that matter for a SaaS business: MRR, churn, ARR by plan, cohort retention curves, and the leading indicators that predict next month's numbers before the billing run.

Questions
The answers we give most often.
- Do you build both the product and the marketing site?
- The product (authenticated app) is our primary scope. Marketing sites are a separate engagement — we can build them or scope them as an add-on. Both are fixed-price.
- What billing infrastructure do you use?
- Stripe Billing for most projects — it covers plans, trials, seats, metered billing, and dunning. Paddle for products that want a merchant of record to handle global tax. We assess which is appropriate in discovery.
- How do you handle the free tier vs paid tier logic?
- Feature flags gated by plan, usage limits enforced at the API layer, and upgrade prompts triggered by behaviour. We design the free-to-paid conversion flow as a UX discipline, not an afterthought.
- Can you integrate with our existing data warehouse?
- Yes. Segment, Mixpanel, Amplitude, BigQuery, Snowflake, and custom analytics pipelines are common integrations. We assess the data model in discovery.
- How long does a SaaS MVP take?
- A focused SaaS MVP (core feature set, auth, billing, basic admin) runs ten to fourteen weeks. A v1 with growth loops, admin analytics, and enterprise SSO runs sixteen to twenty-four weeks.
- What does it cost?
- SaaS MVPs start at $28,000. Full v1 products with enterprise tier features start at $70,000. Fixed-scope proposals after discovery.
