Why Rorix

What a Specialist SaaS Development Agency Looks Like

Most agencies that call themselves SaaS specialists have built one or two SaaS products as part of a broader portfolio. The same engineers have been the core engineering team for B2B SaaS platforms that have been running in production for 5+ years.

Longest Partnership: Since 2018

The agencies that leave after go-live are not SaaS agencies; they are project shops. Our longest client engagement has run since 2018, begun by our founding engineers before Rorix existed and continued under it, because we build architecture that holds up and teams that stay.

Angular & React SaaS Specialists

We have maintained Angular codebases from v14 through v21 and React applications through concurrent rendering and Server Components, in production, not in tutorials.

Dedicated Team, Not Shared Resources

Your engineers are on your account full-time. Named engineers, committed capacity, no rotating pool. The same team that builds sprint one is still on your account in month 18.

Full Code Ownership

Every repository under your GitHub org. Every line of code yours. No proprietary tooling, no lock-in, no negotiation required. Written into every contract.

Multi-Tenant From Day One

We design the tenancy model, data isolation strategy, and auth architecture before sprint one. Building these wrong costs 6 to 18 months to fix. Building them right costs one discovery session.

5.0★ Across 4 Verified Reviews

Every client who has reviewed us on Clutch has rated us 5.0. Four verified reviews is a small sample and we would rather say so than round it up, because the number only means anything if the way we count it holds up.

How to Engage

From Discovery Call to Sprint One

No ambiguity, no bait-and-switch. Here is exactly how a new engagement starts.

01

Agency Fit Call (30 Min)

We discuss your product, stack, and what "done" looks like for you. We will tell you honestly if we are not the right fit, because starting the wrong engagement wastes both sides' time.

02

Technical Discovery

Your tech lead (or ours if you don't have one yet) reviews the current architecture, identifies the first sprint scope, and defines the team composition: frontend, backend, or full-stack.

03

Named Team Commitment

We confirm the specific engineers who will be on your account. You meet them before signing. We document the timezone overlap, communication protocol, and the first sprint scope.

04

Retainer Starts, Sprint One Ships

Two-week sprints. You set priorities. We ship and demo. The same team that builds the first feature is still on your account when you hit your first 1,000 customers.

FAQ

Common Questions About Hiring a SaaS Development Agency

What is the minimum engagement length?

Month-to-month, which works out to a one-month minimum with no long-term lock-in. Optional commitments of 3, 6 or 12 months unlock discounts, but they are never required. In practice most retainers run far longer than the minimum.

Do you work with early-stage startups or only established companies?

Both. We have built greenfield SaaS MVPs from a whiteboard and we have joined products at Series B to scale engineering. The engagement structure adapts to the stage.

What does the handoff look like if we bring engineering in-house?

We build with handoff in mind from day one: documented architecture decisions, clean git history, no proprietary tooling. The 30-day handoff period is written into every contract.

Can I start with a fixed-scope project before committing to a retainer?

Yes. We sometimes start with a scoped integration, a specific feature, or an architecture audit before moving to a retainer. This is a good way to evaluate the team on real work.
