About

Support and web know-how in Nantes for professionals and small businesses that want to see clearly, then make themselves visible.

Sproch · Coaching & Web brings two trades together around one move: helping you decide, then helping you show it. Coaching brings order to priorities; web creation turns the activity into pages you understand in ten seconds.

The business is registered under APE code 82.99Z — support for businesses and professionals — and the national register describes the supply of various support services tailored to their needs. Coaching of professionals and going online both fall within that scope.

Each service produces something written or a deliverable: a summary after a session, a site handed over with its source files. Nothing that does not outlast the service, and nothing that locks you in.

The scope is deliberately clear: no psychological care, no legal or financial advice, no promise of first place on Google. Those limits are written on the site and restated in every service.

Why coaching and web together

Clarifying an activity without making it visible leaves the job half done; putting a confused activity online only spreads the confusion. The two belong together.

Coaching serves to sharpen the offer and the message; the site serves to show them. Nothing requires taking both, but when it happens, the second starts from an already clear direction.

What “delivered with the sources” means

A site handed over without its source files is a dependency: you have to go back to the provider for the smallest change. Here the sources are handed over and the hosting is in your name.

You can take the site over yourself, hand it to someone else, or keep the monthly maintenance. The choice stays yours, at every step.

Confidentiality of sessions and access

Coaching sessions are neither recorded nor shared; only a written summary is sent to you. Technical access given for a site is used for the duration of the service, then returned or deleted.

No subcontractor, no third-party analytics and no transfer outside the European Union. The site loads no external script and sets no tracker.
