## Curator assessment
Reviewed 2026-09-03 by Gabor Kiss against published evidence.

The AI automation line publishes no client case study: the service page says formal studies will follow as projects mature, and offers five representative examples (hotel booking triage on n8n and Claude, Shopify product enrichment on GPT-4o, HubSpot lead enrichment) with typical rather than measured results.

The 11 published case studies are SEO, paid media, web and reputation work, all anonymized, and the one that uses AI does so for review analysis at a Rome hotel, so nothing on the site shows an automation running in production for a named client.

Pricing is published for the AI work—a single workflow at €1,000–12,000, a process diagnosis from €1,000—which frames this as a low-cost first automation rather than an AI engineering engagement.

Best for small hospitality, real-estate or commerce operators who want a marketing agency to wire n8n and a language-model API into their CRM or booking flow, and who will ask for a live reference before signing.

### Key strengths
- A candid service page: it states when classic automation beats a language model, gives typical API running costs (€50–500 a month) and describes fallback behavior when a model API fails
- Handover is designed in—documentation, client access and training, with a stated expectation that simple n8n or Make workflows run in-house after one to two months
- 12 Google reviews at 5.0 and profiles on Clutch, DesignRush and GoodFirms give a four-person named team some third-party footprint

### Good to know
- No AI automation has a published client or measured outcome—ask for one live workflow with its execution volume and error rate before scoping
- Index and case pages disagree: the B2B paid-media study reads 70% lower cost per qualified lead on the index and 58% on its page—ask which version the client signed off
- The team page names four marketing leads and no engineer—confirm who builds and maintains the workflow and what happens when it breaks
