The four levels of branding.

Level 3: Tertiary detail-led branding

Above that, there's a level I don't think has a popular name. I like to call it tertiary detail-led branding.

You've got your colours, font, logo and brand devices, but now you've also crafted a layer of small, considered details underneath them. Custom icon sets. Trim copy and micro-labels that sit alongside visuals. Specific illustration treatments. The kind of finish that separates a Stripe or Linear brand from a seed-stage SaaS brand even when the core elements look superficially similar.

It's hard to describe in the abstract because the whole point is that the detail is specific. But you feel it immediately when you see it. Tertiary detail is what signals maturity. It tells you someone cared, someone had time, someone made decisions at a level most brands never bother with.

A lot of designers skip this level because it's labour-intensive and it's the first thing to get cut when the timeline tightens. But it's often what separates good from genuinely premium.

Level 4: Brand concept-led branding

The highest level is concept-led branding. This is where the whole thing inverts.

At levels 1 through 3, you're working outward from a logo. You pick a mark and then wrap a system around it. At level 4, you start with an idea about the business, and everything else (logo included) flows from that idea.

The example I keep thinking about is a piece of work we did for a company called Outsetter. They're an M&A advisory business, helping founders navigate mergers and acquisitions. We built the whole brand around the concept of a lighthouse. A lighthouse is a signpost. It's the steady thing you navigate by. That captured what Outsetter actually does for their clients, so we worked backwards from there. The logo became a lighthouse. The visual language was watercolour, nautical, weather-worn. Every asset pulled from the same metaphor.

What made it easy to execute, paradoxically, is that the concept was doing the thinking. We weren't reaching for decorative ideas. We were asking, what would a lighthouse-themed version of this page, this deck, this icon look like? The concept gave us the answer every time.

That's the difference. Concept-led branding isn't a mood board. It's a central metaphor that does strategic work. And when it lands, the brand has a reason to exist in a specific form rather than just looking nice.

A few caveats worth making explicit

When I first sketched this out, I was framing it as a strict ladder of quality. The higher the level, the better the brand. I don't think that's quite right, and it's worth being honest about why.

Taste operates at every level. A level 1 brand with exquisite taste (think Apple in its Rams-influenced era) beats a level 4 brand with a weak concept every time. The ladder describes logical sophistication, not final quality. Taste is what separates good from bad inside any given level.

Some brilliant brands live at level 2 deliberately. Mailchimp, is a great example. They're device-led or element-led, and they're excellent because the restraint and craft are world-class. "Concept-led" isn't automatically better. It's a higher-ceiling approach that also comes with a higher floor of difficulty.

And level 4 requires something most briefs don't furnish, which is strategic clarity about what the business actually means. You can't find a central metaphor for a business that hasn't figured out its own positioning. That's why most concept-led work happens later in a company's life, when the strategy is mature enough to be captured in an idea.

Where this meets the real world

At Unlimity, most of our clients are pre-seed to Series B B2B startups. So the question I've been sitting with is: where on this ladder should any given client actually be?

Pre-seed, level 1 is often the right answer. Budgets are tight, the product is changing weekly, and the brand's job is to not embarrass the company at pitch meetings. Something clean and functional is a better use of money than an elaborate system that'll need rebuilding in a year.

Seed and beyond, you'd usually want to move into level 2, and eventually level 3 as the company matures. Level 4 is the interesting one, because it's where strategy becomes the bottleneck. A company can't commission concept-led branding if they don't yet know what concept describes them. That's why you often see companies leap to level 4 around Series A or Series B, when the positioning has been stress-tested and the founders can articulate the metaphor themselves.

What AI changes

One thing I think about a lot: AI is quietly lowering the floor on level 4.

Concept-led branding used to require either illustration chops or a budget for a specialist illustrator. If your concept was a lighthouse, you needed someone who could paint lighthouses. That ruled out a lot of designers, including me, from executing at level 4 visually without hiring help.

That gate is largely gone. I can now generate a cohesive suite of watercolour lighthouse imagery in a few afternoons. The taste still matters, the concept still has to be the right concept, and the execution still has to hold together. But the barrier to reaching level 4 as a small studio has dropped significantly.

Which means the bottleneck is shifting from execution to ideas. Having a good concept is now worth more, relatively, than being able to draw one. That's a real shift in where value sits in the craft, and I suspect it's why you're starting to see more small teams and solo designers produce level 4 work that would have been out of reach five years ago.

Why this matters for founders

If you're a founder looking at your own brand and trying to work out whether it's doing enough work for you, this ladder is a useful diagnostic.

If your brand is just a logo, a palette and a typeface, and you're past Seed, you're probably underinvested. If you've got devices but nothing underneath them, you might be one round of craft away from looking genuinely premium. And if you've got a strong business and a clear story but your brand doesn't reflect any of it, you might be ready for concept-led work even if nobody's offered it to you.

The goal isn't to be at level 4. The goal is to be at the level that matches where your company actually is. Most of the time, the honest answer is one step higher than where the brand currently sits.
