SaaS development for companies past the prototype

You have paying customers and a product that works. What you do not have is a team that can keep shipping while the platform gets harder: the tenancy model you outgrew, the billing edge cases, the SSO request from your largest account. We are a senior product team on a monthly subscription. You get a priority backlog worked through by people who have built this before, rather than a fixed-scope project that ends before the hard part starts.

What usually breaks

The tenancy model. It was fine when every customer looked the same, and then one of them bought a competitor and wanted their data separated, and now every query has a condition in it that nobody wants to touch.

Billing. Proration, mid-cycle upgrades, a customer who wants to be invoiced annually while everyone else is monthly, and the finance team asking why the numbers do not match the dashboard.

Permissions. They start as three roles and end as a table nobody can reason about, and the support tickets are the ones you cannot reproduce.

None of these are hard problems the first time. They are hard because they arrive while you are also shipping the roadmap, and the person who understood the original decision has moved on.

We're more confident than ever that we can support our growing user base because of the foundation ClearSummit built for us. The code base is clean.

SaaS Platforms We've Built

From MVP to scale

RealKey

FinTech SaaS for mortgage processing. Multi-tenant architecture, document workflows, enterprise security requirements.

View Case Study

UltraPress

E-commerce design tool SaaS. Complex product customization with subscription billing and team features.

B2B Platforms

Enterprise SaaS applications with SSO, audit logging, and compliance requirements for regulated industries.

Multi-Tenant Design

Architecture

Multi-tenancy done right from day one.

Shared database with tenant columns? Separate schemas? Separate databases? The right answer depends on your compliance requirements, scale expectations, and cost constraints.

We've built all three. We'll recommend the architecture that fits your product's trajectory, not the one that's easiest to implement today.

Subscription Management

Billing

Billing edge cases will find you.

Prorations, refunds, failed payments, plan changes mid-cycle, usage overages, annual vs. monthly, team seats vs. usage-based—billing gets complex fast.

We integrate with Stripe and architect the billing logic to handle the edge cases before they become support tickets.

How We Work

Validate the Model

Before building, we validate your SaaS model. Pricing strategy, tenant isolation requirements, compliance needs, scale expectations. The architecture depends on where you're going.

Core Platform First

Authentication, multi-tenancy, billing integration, admin dashboard. We build the SaaS infrastructure before the product features so you're not retrofitting later.

Iterative Features

2-week sprints adding product features on top of the solid SaaS foundation. You see working software, test with real tenants, and steer the product.

Launch & Scale

We handle deployment, monitoring, and the scaling challenges that come with growth. Then we stick around for the enterprise features your biggest customers will demand.

Is This Right for You?

We're a good fit if: You're building a multi-tenant SaaS platform. You need subscription billing that handles real-world complexity. You want architecture that scales to enterprise customers.

We're not a good fit if: You're building a simple single-tenant app. You need no-code tools (try Bubble).
