Until July 2025, the home page of the ThinkTribal website said "Unlock Your Data and Digital Capabilities". The Digital Transformation page said "Think Bold". The Strategic Consultancy page said "Think Digital". Project Delivery said "Think Tribal". The Housing page said "Think Digital Innovation", with the previous slogan still bleeding through underneath as a CSS layer that had not been cleared. Five pages, five different slogans, one of them broken on screen.
Each page also carried a different stock image. Purple AI-generated abstract shapes on the home page. A laptop with a sales dashboard on Digital Transformation. A workshop photo on Project Delivery. An isometric illustration on Housing. None of it laddered up to a single point of view. The website looked like five sites bolted together, because in effect it was. The original build was done on Webflow by an agency, parameterised through theme settings, and every time someone wanted to update a page they reached for whatever stock asset was nearest.
I am the CTO. I had not commissioned the original site, and at first I did not want to spend any time on it. Then I tried to send a proposal to a housing association, and realised the cover page of the proposal, the home page of our website, the design of our pitch deck, and the visual layer of the products we were building were each operating from different rules. There was no source of truth. Every artefact drifted independently of the others. The brand was a governance problem dressed up as a marketing one.
Three layers, one source of truth
We rebuilt the brand around a single design system. Three pillars, two modes, one typeface, six output media. The visual system governs everything from the website to the product UI to the Word document the client receives at the end of an engagement. When we needed to fork the system for a product (we have two now) the fork inherits the parent rules and overrides only what it needs to override.
The overrides are deliberate. One product's primary user is a tenant in distress filing a complaint, so the fork uses a sage-green register to lower agitation. The second's primary user is a senior data analyst who needs to trust the screen, so the fork uses a deeper blue register associated with confidence in data. Both forks carry the parent ThinkTribal brand mark alongside a consistently styled product logo. Changing the parent palette propagates to the children. Renaming a product in the parent system updates every co-branding lockup automatically.
We then did the same thing for voice. The visual identity was strong by now. The voice was a single line in the brand skill that said language must be professional, plain, and jargon-free. That sentence was as close as we came to a written voice rule. So while a designer knew what a heading looked like on a slide, nobody knew what the brand sounded like in a LinkedIn post or a board paper. The result was the kind of drift the visual layer used to suffer from, except in prose. Sales emails reached for "transformation journey". LinkedIn posts opened with "Excited to share". Website copy promised to "harness data" and "drive value". The visual identity had moved on. The words on the page had not.
Closing the voice gap took an engagement of its own. Two registers, editorial for outbound and discovery, plain for delivery and post-signature. Five attributes (concrete, restrained, evidential, bilateral, plain English). Channel templates with target word counts and structural openings. An approved lexicon and a banned lexicon. Four named-voice profiles for the executives who post on LinkedIn, each carrying the corporate register while preserving the individual's natural cadence. A pre-publish checklist that runs before any external draft ships.
The third layer is the marketing plan. The audience segmentation, the message-by-channel mapping, the lead-capture and nurture sequence, the placement on the technology adoption curve. It used to be a generic consultancy plan. It now references the named products, the named regulatory frame, the named cases, and the same voice registers as the editorial guide. The plan, the visual, and the voice are now reading from the same rulebook.
What changed at board level
I am writing this to other senior executives because I know what brand inconsistency looks like inside a company that does not have this discipline, and most of them do not. The proposal cover does not match the website hero. The product UI uses a different palette from the marketing site. The pitch deck reaches for a stock photo that nobody approved. The CEO and the CMO post on LinkedIn in two voices that do not sound like the same company. Every one of these is a small drift. Together they tell a buyer that the organisation has no internal alignment, which is the worst signal you send to someone who is about to commit budget to your services.
The fix is not a brand book. Brand books are static, they live in shared drives, and nobody reads them. The fix is a system: a single source of truth, applied through tooling, with explicit rules and explicit checks before anything ships. Visual, voice, and marketing strategy reading from the same source. Forks for products that inherit parent rules. A pre-publish checklist that is a checkbox, not a wish.
The board-level question
If a regulator asked your team tomorrow to show that every public artefact your organisation produces speaks with the same voice and follows the same visual rules, would anyone be able to produce the source of truth they are working from? If the answer is anything other than yes with a link, the drift is already showing in artefacts your buyers have seen. The brand was a governance problem hiding inside a marketing budget. I doubt mine was the only one.
