Länsilinkki Oy

What Länsilinkki Oy does

Länsilinkki Oy is a Finnish licensed telecommunications operator founded in 1991 and headquartered in Turku, wholly-owned by publicly listed LeadDesk Oyj since June 30, 2023. The company serves two distinct customer groups: small and mid-sized businesses (SMBs) in Finland and other telecom operators, with a workforce in the 11-50 employee range. Its product portfolio spans mobile subscriptions (resold over DNA's mobile network), operator services including clearing and interconnection, the Dstny mobile switchboard (rebranded from Soluno in mid-2022), service numbers, and VoIP/SIP-trunk services. The company has applied to Traficom for a new 0900 service number range, indicating ongoing product-surface expansion.

The commercial model is two-pronged. On the SMB side, Länsilinkki sells directly to businesses with entry-level mobile subscriptions starting at €15.90/month, alongside switchboard and SIP-trunk connectivity; named accounts include Wellmedic, Trimet, Hotelli Alma, and BCC Solutions. On the operator side, Länsilinkki operates as a clearing house and interconnection partner to approximately 25 telecom operators, monetizing through clearing fees and inter-operator settlement. Lead-time sales are concentrated under CEO Marko Mäkinen (appointed April 2022), with an explicit B2B growth mandate, and marketing reach has been extended via a sponsorship with Kiekko-Espoo in the Helsinki metropolitan area. The underlying technology stack is conventional licensed-operator telecom: mobile resale via a wholesale partnership with DNA, the Dstny/Soluno switchboard platform, and standards-based VoIP/SIP-trunk delivery — without disclosed AI, ML, or proprietary digital layers.

Revenue is not publicly disclosed as Länsilinkki is a non-listed subsidiary of LeadDesk; based on headcount, subscale SMB subscriber base, and niche operator-services scale, revenue is most plausibly in the low single-digit to low double-digit millions of euros. Strategic positioning is that of a stable, regulated SMB/operator-services telecom reseller being integrated into the LeadDesk group's broader cloud communications and contact-center go-to-market, with potential cross-sell of Dstny-aligned cloud PBX and contact-center products into the existing Finnish installed base.
