Mersch: AI sized for family businesses and trades
TealSpark brings AI consulting and implementation to SMEs, trades and family businesses in Mersch and central Luxembourg. We automate the office work that eats evenings — quotes, invoices, call handling, scheduling — with systems sized for companies of ten people, not ten thousand, and priced accordingly.
01The centre
The middle of the country, in every sense
Mersch is Luxembourg's geographic centre — the point where the Alzette valley meets the road into the Valley of the Seven Castles, a canton seat with a growing population and a business fabric of construction firms, trades, workshops and family enterprises, many of them clustered around the Mierscherbierg activity zone.
These are businesses where the owner still signs every quote. AI helps them not by replacing anyone but by giving back time: the estimate drafted before the van is back from the site, the phone answered while everyone is on a roof or under a floor.
02Sized for you
Built for owner-run companies
Quotes and paperwork off your evenings
Estimates drafted from your price lists and site notes, invoices chased automatically, jobs scheduled sensibly — you review and send instead of typing from scratch at nine at night.
A journey in small, paid-back steps
No transformation programmes here: we find the one process costing you most, fix it, measure the gain, then decide the next step together — investment matched to a family firm's appetite.
A business your successor can run
Processes documented in systems instead of memory, customer history searchable, know-how preserved — modernisation that makes handover to the next generation easier, whenever it comes.
03Worked example
From site visit to signed quote in 24 hours
A heating-and-plumbing firm — the archetypal Mersch-style business — was quoting a week after each site visit and missing calls whenever crews were out. AI-assisted quote drafting plus round-the-clock call answering brought quotes down to a day. No missed calls, no late-night paperwork.
04Before you decide
What owners want to know
Often more than for a corporation, proportionally. In a small team the owner personally absorbs the admin overflow, so hours returned land directly where they count. A single well-chosen system — quoting, say — routinely pays for itself within months in a trades business.
secretaire.lu is TealSpark's AI receptionist: it answers your phone around the clock in five languages, books appointments and sends you a summary of every call. It fits trades and practices perfectly — live within 48 hours, with nothing to install on your side.
No. Most of our Mersch-sized clients have no IT department at all. We set everything up, connect the tools you already use, and remain the ongoing point of contact. If something behaves oddly, you call us — that's the whole procedure.
