Construction companies in Switzerland — nationwide B2B lead lists

What you'll find scraping construction companies across Switzerland

Switzerland is multilingual — German across most of the country, French in the west, Italian in the south — and its business base spreads across Zurich, Geneva, Basel, Bern and Lausanne. Zurich is the largest market. Search German for most of the country and add a French pass for Geneva, Lausanne and the western cantons.

For construction companies specifically, the size of the national list depends on how many cities and sub-categories you search: a single query returns a slice, while a city-by-city sweep can surface thousands of businesses across Switzerland. Expect a little over half to list a website — the rest you can still reach by phone. The major markets to search are:

• Zurich
• Geneva
• Basel
• Bern
• Lausanne

The best way to scrape Switzerland nationwide

Open the Google Maps scraper and set the country to Switzerland. The setting that matters most is the search term: search for the German word Bauunternehmen rather than "construction company", since businesses across Switzerland write their profiles in German. Google caps each query at roughly 120 results, so Switzerland is best covered by running its major cities as separate regions in one job — Kavex deduplicates on place ID across them, so no business is ever returned twice.

• Search in German for most of Switzerland; add a French pass for Geneva, Lausanne and the west.
• Zurich, Geneva and Basel hold most of the national market — start there.
• Kavex deduplicates on place ID across regions, so overlapping searches never double-count.
• Add Bern, Lausanne and Winterthur to extend coverage across the cantons.

What the nationwide construction company export looks like

Every job downloads as one CSV with a single construction company per row, no matter how many cities it spans. Each row carries the business name, full address, phone number, website, primary category, star rating and review count, with a website-extracted email added wherever one is published. A national export looks like this:

• One deduplicated row per business across every city searched.
• A Zurich construction company: phone, website and a website-extracted email.
• A Geneva listing: phone and website present, no public email — still reachable by phone.
• A smaller-city construction company: phone only, ready for a Phone Validator pass before any call.

Enrich and personalise before you reach out

Toggle "Include emails" so the scraper visits each construction company website and extracts a contact address, then run those through the Email Verifier to drop anything undeliverable. The Phone Validator sorts the remaining numbers into mobile and landline, and the AI Personalizer turns each row into a short cold email referencing the business and its city — far stronger than a single national mail-merge blast.
