Illustration · no client data
Context
A Swiss consulting startup with no technical infrastructure: no website, no CRM, nothing connecting them.
What I did
Set up domains, DNS and mailboxes, built the bilingual website asande.ch, connected its forms to Zoho CRM and automated workflows that enrich deals with an AI scraper. All of it handed over with documentation.
Outcome
One connected system with the CRM as the single source of truth; enquiries land there automatically.
