SaaS architecture decided before it gets expensive

MVPs, multi-tenant platforms, APIs, data and cloud infrastructure — engineered by the same team that owns your technical SEO. Tenant isolation, clean data models and observability treated as requirements, so the product scales and ships ready to rank.

  • Multi-tenant & RBAC — our home turf
  • A real MVP in weeks, on foundations that last
  • Core Web Vitals & crawlability as requirements

What does REO Rank's SaaS Architecture service deliver?

REO Rank engineers SaaS products end-to-end — MVPs, multi-tenant platforms, APIs, data and cloud infrastructure — with tenant isolation, tests and observability treated as requirements. The same team owns your technical SEO, so the product ships fast, crawlable and structured to rank from day one.

  • A real MVP in weeks, on foundations you won't have to throw away
  • Multi-tenant isolation and RBAC — the platform this very site runs on is our own
  • Core Web Vitals and SSR treated as requirements, not afterthoughts
  • You own the repo, cloud accounts and full IP — no platform lock-in
How an engagement runs

Scope, ship, harden.

Small, sequenced and reviewable — you always know what’s next and why.

  1. Scope & architectMap the smallest valuable slice and the architecture that survives growth. You sign off before we build.
  2. Build the MVPShip a real product on clean foundations — auth, data model, CI/CD — in front of users in weeks.
  3. Harden & scaleIsolation, tests, observability and cost guardrails as usage climbs — no rewrite required.
Non-negotiables

What “production-grade” actually means.

Secure by default

Auth, RBAC, secrets management and least-privilege from the first commit.

Tested

Unit, integration and e2e with CI gates — so a merge can’t quietly break prod.

Observable

Logs, metrics, traces and alerts you can act on before customers notice.

Cost-aware

Right-sized infrastructure with guardrails, so the cloud bill doesn’t surprise you.

Fast & crawlable

Core Web Vitals and SSR treated as requirements — the product ships ready to rank.

Documented

ADRs, runbooks and API docs, so the next engineer (or you) isn’t guessing.

What we build

The builds teams bring us.

From a founder’s first version to scaling a platform past its prototype — the same senior team, engineered to rank from day one.

Founder MVPs (0 → 1)

A real product in front of users in weeks, built on foundations you won’t have to throw away — auth, data model, CI/CD done properly the first time.

Multi-tenant B2B platforms

Per-tenant isolation, RBAC, admin and billing — the hard parts of B2B SaaS. It’s our home turf: this very site runs on an OU-scoped multi-tenant platform we built.

Scaling past the prototype

The “it works but it won’t scale” moment. We harden isolation, tests, observability and cost — without the full rewrite most teams brace for.

Internal tools & portals

Ops dashboards, customer portals and admin tooling that replace spreadsheets and manual work — fast to ship, boring to run.

APIs & integration platforms

The backend other products build on — clean REST/GraphQL, queues, webhooks and the docs that make an API actually adoptable.

Technical due diligence

A senior read on a codebase before you buy, invest or take it over — what’s solid, what’s debt, and what it really costs to move forward.

Why builds stall

Where SaaS builds go wrong — and what we do instead.

The four failure modes we see most often when a team brings us a stalled build. We engineer against each from the first commit.

Built to scale before it works

Teams over-engineer for millions of users they don’t have yet and ship late. We build the smallest architecture that’s correct now and extends cleanly later — no premature microservices, no wasted quarters.

Multi-tenancy retrofitted late

Bolting per-tenant isolation onto a single-tenant app is the expensive rewrite most B2B SaaS hits at the worst possible time. We design provable isolation and RBAC from the first migration, because we’ve run it in production.

Shipped without observability

You can’t fix what you can’t see. Logs, metrics, traces and alerts go in from day one, so a regression surfaces on a dashboard — not in a customer’s angry email three weeks later.

SEO bolted on at the end

A fast, rankable front end is an architecture decision, not a plugin. We treat SSR, Core Web Vitals and crawlability as build requirements, so the product ships ready to be found instead of needing a rescue later.

Scope & ownership

Priced in phases. Owned by you.

The two things that make a build feel risky — an open-ended meter and platform lock-in — removed by default.

Scoped, phased pricing

Each phase has a fixed scope and a clear deliverable — not an open-ended hourly meter. You approve the next phase before it starts and can stop between phases.

You own all of it

The repository, the cloud accounts and the full IP are yours. We build in your infrastructure, with no proprietary platform you can’t walk away from.

Rolling terms after MVP

Once the MVP ships we run on rolling monthly terms — keep us for maintenance and iteration, or take a documented codebase to your own team. No lock-in either way.

How a SaaS Architecture engagement is run

How we work

Why teams bring us in to build the platform

Most of what makes a SaaS platform expensive later is decided in the first fortnight, by someone moving fast. These are the decisions we insist on taking deliberately, and what you own at the end of them.

The decision we will not defer
Tenancy. Whether data is isolated per customer, and how, is the one choice that cannot be retrofitted cheaply — we settle it in week one, in writing, with the cost of each option stated.
What "production-grade" means here
Tests that run in CI, structured logging and monitoring wired before launch, documented runbooks, and an environment your own engineers can deploy without us in the room.
Who writes the code
Named engineers you can look up, not a rotating pool and not a subcontractor you will never be introduced to. Meet them
What you own at the end
The repository, the infrastructure, the credentials and the documentation. No proprietary layer you have to keep paying us to operate, and a handover session rather than a zip file.
What it costs
Published, not quoted on request. A discovery and architecture engagement from $1,000, credited against the build; delivery from $2,500 a month, with larger builds scoped per phase once discovery is done. Full pricing
How it runs

The expensive decisions first, while they are still cheap

A platform gets expensive in month eighteen because of what was decided in week one. This order is deliberate: the choices that are costly to reverse are taken and written down before anybody writes a feature.

What happens at each stage
  1. Week 1Discovery, and the tenancy decision
  2. Week 1–2Architecture written down, with its costs
  3. Weeks 2–4One slice built end to end
  4. Weeks 4–8MVP in front of real users
  5. Weeks 8–10Observability before scale, not after
  6. Weeks 10–12Hardening: auth, limits, backups
  7. Month 3+Handover your engineers can deploy from
  8. OngoingCost per customer, watched
Before you commit

The decisions that are expensive to reverse and the words they turn on

A platform build is a sequence of choices that get costly to unpick. These are the comparisons worth settling first, and the terms the architecture conversation assumes you already know.

The words these decisions turn on

From our clients

What clients say about working with us

Real names, real people, and an honest caveat: these review our search and content work rather than a platform build. The engineering references we can give you are on a call, not on a page.

Questions founders ask

Before you commit a sprint

The things technical and non-technical buyers both check.

Do you build it, or just advise?
We build. We can also run a technical due-diligence read first and take over an existing codebase — but the point of this pillar is that we ship software, not slide decks.
What stack do you use?
Pragmatic and boring-on-purpose: TypeScript across the board, Node and Angular/React, Postgres, and a mainstream cloud. We choose for fit and longevity, not novelty.
Can you take over our existing product?
Yes — usually after a short due-diligence pass so we both know what we’re inheriting. We stabilise, document and then move it forward rather than rewriting on day one.
How do you handle multi-tenancy and security?
It’s our home turf — the platform this very site runs on is OU-scoped, multi-tenant with role-based access. We design provable isolation, RBAC and per-tenant limits early, because retrofitting them is the expensive path.
How fast is an MVP?
Weeks, not quarters, because we scope hard and build on foundations instead of shortcuts. You get something real in front of users early and iterate from data.
Do you handle the SEO side too?
That’s the whole idea. The same team that architects your platform owns your technical SEO, so the product ships fast, crawlable and structured to be found — not something you have to fix later.
How do you price a build?
By scoped phases with a clear deliverable, not an open-ended hourly meter. We fix the scope of each phase up front and run on rolling terms after MVP, so you’re always in control of spend and can stop between phases.
What do we own — code, infrastructure, IP?
All of it. The repository, the cloud accounts and full IP are yours. We build in your infrastructure where you want it, with no proprietary platform lock-in you can’t walk away from.
Do you maintain what you build, or hand it off?
Either. We can hand off a documented codebase to your team, or stay on to monitor, maintain and evolve it — including keeping Core Web Vitals and the SEO you paid for from regressing.
How do you avoid the MVP that becomes tech debt?
By refusing the false choice between fast and clean. We scope the smallest valuable slice, then build it on real foundations — typed code, tests, CI/CD, a sane data model — so the MVP is the first version of the real thing, not a throwaway you rewrite in a year.

The team

The engineers who would actually build it

A platform is not staffed from a pool here. These are the people who would take the architecture decisions, write the code and hand you the keys — and you can look both of them up before anything is signed.
