Who this is for

You'll feel at home here if…

Founders rebuilding a tired site

Your current site doesn't match the company you've become. You want a flagship, not a Wix patch-up.

Scale-ups outgrowing Webflow

You've hit the wall on no-code — performance, integrations, custom logic. Time for real engineering.

SaaS teams without a design system

The product works but looks shipped by ten different people. We unify it into one credible surface.

What you walk away with

Outcomes, not outputs.

  • A site or product that genuinely reflects your brand and ambition.

  • A codebase you can hand to any future team without an apology.

  • Foundations for SEO, paid acquisition and analytics built in from day one.

The cost of getting this wrong

Where most engagements leak money.

Without us
  • A slow site quietly bleeds 7% of revenue for every extra second of load time.

  • Template builders trap you — you can't extend, integrate or migrate without a rebuild.

  • Pretty designs that don't convert are an expensive Dribbble post, not a website.

  • Six-month builds that ship one big bang nobody trusts.

With MJM Connect
  • Sub-1s LCP, edge-cached, lazy-loaded. Speed is a feature here, not an afterthought.

  • Open React codebase in your GitHub. Any agency on earth can pick it up tomorrow.

  • Every section ships with a CTA, an analytics event and a hypothesis we can measure.

  • Weekly preview links. You see the site grow live. No surprises on launch day.

What we do

Capabilities under this roof.

Design systems

Our approach

How an engagement actually runs.

01

Discover

Goals, users, jobs-to-be-done and a sharp definition of done.

02

Design

Brand-led UI in Figma, prototyped at fidelity before a line of code.

03

Build

Modern React stack, shipped in weekly cycles with previews you can poke at.

04

Scale

Performance, SEO, analytics and ongoing iteration after launch.

Case study
The brief

An Australian car marketplace launching into a category dominated by two incumbents — and needing a product that felt instantly more modern, faster and more trustworthy than both.

What we did

End-to-end product design, full-stack engineering on a Supabase + React stack, custom listing search, seller dashboards, payments, and a marketing site engineered for SEO from day one.

The result

Hit 10k MAU within six months of launch, with sub-1s page loads and an organic share of voice that broke into the top 5 nationally for high-intent terms.

MJM didn't just build us a website — they built us a product. Weekly demos, zero hand-waving, and a codebase our in-house team could pick up without a single 'who wrote this' moment.
