SaaS engineering
built for growth,
not just launch
We build B2B SaaS platforms that scale past the first hundred customers without a full architectural rewrite. Multi-tenant infrastructure, usage-based billing, self-serve onboarding - engineered for the product-led growth motion from day one.
SaaS engineering, every layer
From the data model to the billing integration to the self-serve onboarding flow — we build the infrastructure that lets your product team ship features instead of fighting architecture.
Discuss your platformMulti-Tenant Architecture
The data model and access control architecture you get at day one has more impact on your growth ceiling than any single feature decision. We design multi-tenant systems - silo, pool, or bridge - with tenant isolation, per-tenant configuration, and data residency boundaries that hold at 50,000 tenants as well as they do at 50. No big rewrites at Series B.
Usage-Based & Subscription Billing
Billing infrastructure that handles what Stripe's docs make look simple but isn't - metered usage across multiple dimensions, mid-cycle plan changes, prorated credits, trial-to-paid conversion, dunning logic, and revenue recognition. We've integrated with Stripe, Chargebee, and Paddle for SaaS companies from seed to $50M ARR, and we build the internal billing portal your CS team actually needs.
Self-Serve Onboarding & PLG Infrastructure
The difference between a product that grows with sales and one that grows without them is how well the onboarding works. We engineer the full self-serve funnel - sign-up flow, interactive setup wizards, empty-state design, activation event tracking, and the in-product prompts that move new users to the moment they first get value. Then we instrument it so your team can see exactly where people fall off.
Admin Portals & Internal Tooling
Every SaaS company eventually needs internal tools - the operations dashboard where your support team manages accounts, the billing console that handles refunds and plan overrides, the feature flag system that controls rollouts. We build these properly so your team stops doing things manually in the database and starts doing them in a tool with guardrails.
Product Analytics & Growth Infrastructure
Instrumentation that gives your product team answers rather than data. We design the event taxonomy, implement it across your stack with Segment or Rudderstack, build the warehouse pipeline into Snowflake or BigQuery, and connect it to the dashboards your growth team actually uses - Amplitude, Mixpanel, or a custom BI layer. You'll know your activation rate, feature adoption, and cohort retention before the next board meeting.
SaaS Infrastructure & Reliability
The infrastructure underneath the product - multi-region deployments, tenant-aware caching, background job processing that doesn't affect foreground performance, database query performance under load, and the observability layer that tells you which tenant is causing the spike. We've scaled SaaS platforms from 100 to 100,000 tenants and know exactly where the ceiling tends to appear first.
Built for where you're
going, not just where you are
SaaS architecture decisions compound over time. The ones made at 50 customers still constrain you at 50,000. We think ahead without over-engineering.
MVP to Product-Market Fit
Fast, lean architecture that ships in 8 weeks. Shared-schema multi-tenancy with row-level security, basic billing integration, and the instrumentation you need to measure activation - without the infrastructure debt that slows down iteration.
Scaling the Core
The inflection where most SaaS architectures start showing cracks. We migrate to a more isolated tenancy model, introduce usage-based billing, build proper admin tooling for your CS team, and instrument the funnel with cohort-level analytics that drive retention work.
Enterprise-Grade Scale
Multi-region deployments, tenant-aware query optimisation, enterprise SSO and SCIM provisioning, advanced feature flagging, custom enterprise contract support, and the data infrastructure to run a sophisticated PLG motion alongside direct sales.
What changes when the
infrastructure is right
Bad SaaS architecture doesn't stop growth immediately - it taxes it. Every feature takes longer, every incident affects more tenants, and every pricing change requires a sprint. These are the outcomes we see after fixing it.
Faster feature shipping
When multi-tenancy is solved at the data layer and billing is decoupled from application code, engineers stop touching infrastructure every time they build a feature. Sprint velocity typically doubles within three months of a proper architectural rebuild.
Better self-serve conversion
Properly instrumented onboarding with clear activation milestones and in-product nudges consistently lifts trial-to-paid conversion. The average improvement across our SaaS clients is 34% within 60 days of launching a rebuilt onboarding flow.
Lower infrastructure cost at scale
Shared-nothing tenancy and tenant-aware caching dramatically reduce compute cost per tenant as the platform scales. We've seen infrastructure cost per tenant drop by 60% between 1,000 and 50,000 tenants on well-designed platforms.
Enterprise deals that actually close
Large enterprises consistently ask for SSO, SCIM, audit logs, data residency, and security questionnaire answers. When these are built properly, deals stop stalling in security review. The clients who add enterprise-readiness typically close their first $50k+ deal within four months.
What we've shipped
and what changed
Numbers from production SaaS platforms - not projections from a pitch deck.
Multi-tenant rebuild: from Heroku to 10,000 tenants on GKE
A B2B analytics platform hitting Heroku limits with 800 customers and a shared-schema architecture that was causing inter-tenant performance bleed. We migrated to schema-per-tenant on GKE with tenant-aware connection pooling, rebuilt the billing integration with usage-based metering, and launched a self-serve onboarding flow that replaced a 3-day sales-assisted setup.
PLG infrastructure: self-serve converted 34% more trials
An HR management SaaS with a strong product but a friction-heavy trial that required a sales call to complete setup. We redesigned the onboarding as a self-serve wizard, instrumented every activation milestone with Segment, built the in-app tooltip layer, and connected it all to Amplitude dashboards the growth team could act on. No sales call required for 80% of trials within 90 days.
MVP to $2.4M ARR in 18 months with usage-based billing
A developer tooling startup building on a prototype that had validated the idea but wouldn't survive 100 paying customers. We rebuilt the platform from the first sprint - multi-tenant data model, usage metering across 4 billing dimensions, a public API with rate limiting per plan, and the admin tooling the founders needed to manage accounts without engineering support. 18 months later: 1,200 customers, $2.4M ARR, Series B term sheet.
What we build with
Opinionated but not dogmatic - the right tool for each layer, not the one we happen to know best.
