About Stéphane

You are a manager / founder of your company or Marketing / SEO / e-commerce Director and you are tired of being poorly supported for your online visibility.

Agencies are far too expensive because they pay for premises, administration, advertising, branding.
Their objective is for things to purr along, in order to bill ad vitam aeternam in subscription mode.

What you need is a non-agency, a task force, focused on Quick Wins, but also on the long-term vision.

This is in order to meet your challenges, thanks to tailor-made processes and data:

❓ Determine the best e-commerce / SEO strategy.
❓ Save valuable time by integrating AI into processes.
❓ Boost the Return On Investment of acquisition channels.
❓ Compensate for the lack of internal resources to execute acquisition strategies.
❓ Improve an insufficient conversion rate.

After 13 years in an agency, 10 years managing my e-commerce, 10 more years as manager of this non-agency, the results speak for themselves:
+650 clients supported, from individual entrepreneurs to large groups such as JouéClub.
+85% see their profitability increase very strongly.
+75 testimonials in LinkedIn.
