Colossales: the website of a Kanban CRM that lives inside Gmail

The project

Colossales is a Chrome extension: a Kanban CRM attached to Gmail threads. Pipeline, comments and follow-up reminders stay on the email. The salesperson never opens another tool. The product syncs with Google Sheets, ships as a free tier and a Pro plan, and is built for people who sell from their inbox.

Our brief: design the bilingual showcase site that makes the product clear in a few screens and drives installs. The brand identity (naming, logo) was already in place. The site is its translation: promise, demonstration, try-it journey.

Technical constraints

• Showing a product with no interface of its own: it lives inside Gmail. The visitor has to see the Kanban in the inbox, not an abstract screenshot.
• Bilingual FR/EN from the start: mirror URLs, a language switch, the same pages on both sides.
• Two offers (free and Pro) without breaking the install journey.
• A fast, indexable foundation, for a niche query: a CRM inside Gmail.

Marketing constraints

• The promise fits in one sentence: your pipeline, without leaving Gmail.
• Reassuring people about daily use (sorting, follow-ups, team sharing) without a feature catalogue.
• Two clear actions: install the extension, or explore the Pro plan.

Our solution

• A homepage that states the promise, then shows the product inside Gmail: a demo Kanban, from the email to the deal.
• A short hierarchy: features, a four-step method, the Pro plan, frequently asked questions.
• A bilingual journey aimed at installation, with the Pro plan as the second lever.

Results & deliverables

• A bilingual product site live, aligned with the brand identity.
• A technical tool made readable: you see where it lives, what it does, and how to try it.
• Two conversion doors: the free install and the Pro plan.
