Hugo Bouchillou

CEO @Cycle Events

Most agencies make a great first impression and sell you the dream in those early conversations, but that illusion fades fast once the contract is signed. With Gemeos, it’s different. Gemeos are professional and genuinely committed to doing things right and fast. I really recommend them. And this is the first time I’ve ever recommended an agency.

The Web Challenges Unique to the Events Industry

The five biggest challenges are visual impact, ticketing or lead qualification, mobile performance, content seasonality, and the ability to measure journeys that are often fragmented across the site, CRM, and external tools.

Create visual impact without slowing down the site

Problem

Event pages rely heavily on photos, videos, and animations. Without discipline, media weight slows things down right when users want to buy or check information on mobile.

Solution

We treat every asset as a conversion lever: the right formats, compression, lazy loading, visual prioritization, and interactions that actually support the story.

Indicator

Core Web Vitals, mobile load times, gallery engagement, CTA clicks, and exit rates on media-rich pages.

Connect the site to ticketing or quotes without breaking the user journey

Problem

Switching to an external ticketing tool, calendar, or form can break the design, the context, and the tracking.

Solution

We map the entire journey end to end, from the event page to payment, sign-up, or a quote request. Messaging, campaign settings, and analytics events are checked before launch.

Indicator

Clicks to ticketing, conversion rate, drop-off after leaving the site, completed inquiries, and attributable revenue when data is available.

Design for mobile first, and for launch-day use cases.

Problem

Schedules, maps, tickets, QR codes, transport, or schedule changes are all checked on the go. A page designed for desktop only quickly becomes unusable in the field.

Solution

We prioritize context-relevant information: quick access, persistent CTAs where relevant, a readable schedule, practical details, availability status, and components tested on small screens.

Indicator

mobile traffic share, mobile conversion rate, clicks for directions, views of practical information, and form error rate.

Managing seasonality without rebuilding the site after every edition

Problem

Many websites become obsolete just days after the event, then get replaced the following year, losing content, URLs, and SEO signals.

Solution

We structure the CMS around editions, events, speakers, artists, venues, and resources. Useful legacy pages stay accessible, while active content gets updated without unnecessary URL changes.

Indicator

update time, off-season traffic, content reuse, indexing of legacy pages, and the time it takes to publish a new edition.

Measuring Acquisition Across Cross-Device Journeys and Stricter Consent Rules

Problem

A user might discover an event on mobile, come back on desktop, and buy later. At the same time, the CNIL updated its 2026 guidance on cross-device consent and reminds businesses that they need to be able to prove consent.

Solution

We define the events that actually matter, cut unnecessary trackers, and set up the CMP, domains, and third-party tools before launch. Compliance decisions are approved by the right stakeholders.

Indicator

consent rate, attribution quality, assisted conversions, tracking errors, discrepancies between ticket sales and analytics.

Events presented like a catalog of editions, with no distinction between audiences or conversion goals.

We structure each event journey around attendees, exhibitors, sponsors, and the event’s goals.

Ticketing, registration, and sales inquiries are handled as isolated external links.

Ticketing, registration, and CRM are integrated into one seamless journey, with the right context at every step.

Program, speakers, venues, and partners are published without a reusable structure from one edition to the next.

The CMS organizes editions, sessions, speakers, venues, and partners to make updates easier.

Design often prioritizes visual impact without always accounting for performance or traffic spikes.

The design is built with performance, mobile, and scalability in mind.

SEO is handled after launch on a few event pages.

SEO and GEO shape events, themes, locations, and content before the wireframes.

Reporting is limited to visits and sign-ups, with no link between campaigns, content, and revenue.

Tracking connects acquisition, sign-up, participation, and commercial opportunities whenever possible.

Branding

Build a strong, memorable brand identity that reflects your positioning and builds trust at every touchpoint.

Design

Interfaces designed to convert — clear, consistent, and aligned with your users’ expectations.

Development

A fast, scalable site that’s easy to evolve — thanks to a clean, high-performance Website build.

SEO/GEO

Boost your visibility on Google and AI search engines to attract qualified, long-term traffic.

CRO/Growth

Continuous analysis, testing, and optimization to turn more visitors into customers.

Dedicated team

A hands-on team by your side, here for the long haul — helping your site evolve with your business goals.

Professional, responsive, and committed to their clients' success, Gemeos is the first agency I recommend without hesitation.

VP Marketing @Paradox

We worked with Gemeos in the summer of 2024 to redesign Modjo’s marketing site and better reflect the brand’s new positioning. The collaboration was incredibly efficient, the agency was highly responsive and adapted to every unexpected challenge. With limited resources on our side, right in the middle of summer, we launched the new site in just six weeks. Site visit engagement increased by 58%!

“Gemeos are the perfect experts to take over your website from A to Z. Beyond being highly skilled, they were proactive and came up with great ideas throughout the project, a real plus! Thanks for this fantastic Openeat website redesign ;)”

Leo Carli

Product Marketing Manager @Nuant

We worked with Gemeos for several months on the redesign of our site and the launch of our new Taalent.ai offering in the U.S. market. The team was able to combine strategic vision, high-quality execution, and great responsiveness throughout the project. An effective collaboration that I’d recommend without hesitation.

Efficiency, structure, and performance. Gemeos managed to translate Avnear’s identity into a website that exceeded our expectations. Client feedback has been unanimous. The team showed remarkable agility in adapting to our requests and our high standards. A trusted partner we’d recommend without hesitation. Our site is a masterclass in building trust.

Charley Arod

Founding Partner. Asset & Risk Management @Avnear

Gemeos worked on the Webflow integration as part of our website redesign, with the goal of giving our Growth team back control over landing page creation and improving web performance and SEO. I highly recommend Sandro for his availability, responsiveness, teaching approach, and, above all, his understanding of our business needs.

Florian Corteel

Thanks to the whole team, always going the extra mile to push the boundaries!

Florent Darrault

CMO @Cureety

We entrusted Gemeos with a full website redesign and migration, and everything went incredibly smoothly. What stood out most to us was the quality of the art direction: a truly premium, cohesive visual direction, with a clear visual identity and highly polished choices throughout — typography, colors, iconography, pacing, hierarchy, and more. You can tell they have great taste, and above all, a real eye for detail on every screen. On top of that, the team is incredibly responsive and very experienced: they know both design and the technical side inside out. I’d recommend them without hesitation.

David BERNARD

CEO & Founder @AssessFirst

Sacha & Sandro worked on the redesign and migration of our website with a few clear goals: create a unique, differentiated visual identity, clarify our message and value proposition, smooth out the customer journey, and ultimately generate more business opportunities. We’re very happy with the result, and the numbers speak for themselves. Sacha & Sandro are skilled, committed, conscientious, passionate, and they see things through to the end. I highly recommend them!
