The Commercial Foundation

More marketing only makes more noise.

When your market looks and sounds the same, more marketing only makes more noise.

The Commercial Foundation finds the reason customers should choose you - one that is true and that they value - then gives every brand, marketing and advertising decision a clear job to do. It does not copy competitors or guess at customers.

One team, one Foundation

Every discipline, working from the same brief

Specialists in strategy, creative, marketing and growth, public relations, development and design work as one aligned team, from one shared brief - the Commercial Foundation where there is one - so the identity, the campaign, the website and the product all argue the same thing.

Development division

We don’t just market the destination. We build it.

Strategic websites, web and mobile apps and prototypes, built to do a clear job for the business.

Where you have a Commercial Foundation, it guides what we build, how it works and what it has to achieve. You own the code, the accounts and the repository outright.

How the work connects

From strategy to expression to growth

Three chapters of one relationship. Each is scoped on its own, and nobody has to buy every chapter.

  1. Where we start

    Commercial Foundation

    Establish the buyer insight, positioning, offer and story that give the brand its direction. Agree what matters before deciding what to make.

  2. What we create

    Brand and creative

    Turn that direction into a compelling brand idea, identity, messaging and campaigns. Build the expression around what the brand needs to communicate and how it should make people feel.

  3. How it reaches people

    Activation and growth

    Bring the brand to market through the appropriate marketing, website and selected development work. Learn from the response and improve the agreed work over time.

Before you ask

The questions that usually come first

Where does working with you start?

Wherever you need us most. The Commercial Foundation is the best place to start, because it settles the buyer insight, positioning, offer and story everything else is built from. If your brand is already clear and you need one service now - social media, SEO, PR, a website - we can start there. Before you commit, we confirm the scope, the fee and the dates in a written proposal.

Do we have to buy everything from you?

No. The Foundation stands on its own, and you can take it to your own team or another supplier. If you want us to carry it into identity, campaigns, growth or development, each piece is scoped separately. There is no automatic retainer.

What does it cost?

Every engagement is quoted in a written proposal once we understand what needs to be done. The proposal confirms the scope, the fee and the dates before you commit, so nothing important is left vague.

We have not launched yet. Can you still help?

Yes, from a different starting point. The standard Foundation is built for a business with paying customers, one priority offer and a decision-maker ready to take part. An offer that has not launched gets a separately scoped research engagement suited to the evidence available.

What could your brand become?

Tell us about your business, where you are now and what you want to achieve. We will discuss whether Assay House is the right partner and what a useful first step could look like.

The direction first, then the work it calls for. That is how a creative agency South Africa's ambitious businesses can rely on should work.
