Co-branding: merging two identity systems
Four models of merging — and this is not just "logo on the left, logo on the right"
Most agencies stop at the banal placement of two signs through a separating line. This is not architecture, but its absence. Four working models have taken root in the industry, and the choice between them is determined not by aesthetics, but by the structure of relationships between the brands.
| Model | Essence | When to apply |
|---|---|---|
| Host/Guest | One brand owns the visual system (typography, color, grid), the second is embedded as a supporting element | One-time collaboration, information partnership, special project within the host platform |
| Fusion | Both logos retain independence, but are united by a common compositional principle — a new form that does not belong to either brand | Merging of equally weighted companies, where it is important to show "1+1=3" |
| Endorsed Fusion | Fusion hybrid: a new unifying form plus explicit confirmation of both original brands side by side | Reorganization of the product line within the company group, rebranding after a merger |
| Hybrid (permanent) | Logos are reworked according to a unified structural logic, but remain visually different in character | Long-term partnership with a established market base on both sides |
Meta and Red Hat have established Host/Guest as the foundational model for any collaborative communications in their respective guidelines: the channel owner dictates the visual language, and the partner is a guest in this language, not a co-author on equal footing.
Proportions: why 60:40 works better than 50:50
Intuition suggests dividing space equally. In practice, equal proportions visually compete with each other — the eye does not understand where to look first, and this is perceived as uncertainty, not as partnership. Airbus, followed by Meta and Red Hat, have established the rule 60:40: one logo takes up noticeably more space, the second — noticeably less, but not so much as to look like a decorative signature.
This rule works not only with size, but also with reading order, color weight, and vertical position. The dominant element is usually placed higher or to the left in the reading direction — this creates a natural hierarchy without the need to explain it in text.
What to do with conflicting palettes and fonts
Mixing the official colors of both brands in one layout is a common but losing tactic. The result is almost always muddy, because each palette has its own internal logic of contrast, and merging two logics mechanically does not work.
- Choose a neutral backdrop — white, black, or the brand's official gray — and place both colors as accents, not as backgrounds for each other
- Establish a single grid and module of spacing for both logos, even if their internal proportions are different — this creates visual discipline over differences
- Do not touch the typography of the logos, but unify the font set for all joint materials — one grotesque for text resolves half the conflict
- Set a common principle for constructing the mark, not a common style — this is what REON and Wellmix did: they reworked the logos according to a unified structural logic, preserving the character of each brand
The REON + Wellmix case is illustrative in that this is not hybridization nor Host/Guest, but a third way — synchronization of methodology with full preservation of individuality. Such a model requires that both brands already have a stable market base: there is no need to rebuild identity from scratch here.
A separate neutral identity or elements of both brands — how to decide
The question sounds simpler than it actually is. A separate neutral system is needed when a joint product lives longer than the fact of partnership and should be perceived independently—as a separate entity, not as a temporary showcase of two logos. Example — Nomad Insurance and Nomad Life: instead of blending the signs, a recurring form is used, a square in a square, symbolizing the idea of «1+1=3». This is not a logo compromise, but a third object that stands next to both brands, not between them.
If, however, the partnership is time-limited or the product clearly belongs to one of the brands (special collection, limited edition, event), a neutral system is excessive — here the Host/Guest approach works without creating a new visual object.
Why logo blending almost always fails
Hybridization — an attempt to create one sign from elements of two logos — looks like a logical compromise at the briefing stage and almost always fails at the implementation stage. The effect received a working name Frankenstein effect: the audience does not read such a sign as belonging to brand A, nor as belonging to brand B, but perceives it as visual noise with an unclear status. The maximum that such a hybrid is good for — a transitional solution for 1–2 years during company merger, when the market needs time to get used to the new name. As a permanent construction, a hybrid almost never works.
Here it is worth developing two different scenarios, which in competitor articles are usually mixed together. Transitional identity in a merger — a temporary visual bridge, its task is to disappear after rebranding. A permanent co-branding construction — Host/Guest, Fusion or Endorsed Fusion — is designed for years of joint existence of two independent brands and does not imply the disappearance of either of them.
Design will not save a bad brand fit
Any of the four models falls apart if the brands lack meaningful alignment. The study of the co-brand Adidas and Samsung showed: the joint product received a positive rating +3.56, whereas Adidas entering the phone market separately, without a partner, received -4.37. The difference is not in logos or proportions — it is that the audience believed in the meaningfulness of the alliance between exactly those two companies. Technically flawless identity architecture cannot compensate for the lack of such alignment: first, the logic of the partnership is checked, and only then is the model of visual systems combination chosen.
