Company profile
researched Aug 2026Koll, operated by Koll Group Oy, is a Finnish software company whose product is a business calling application that attaches the caller's verified identity and the subject of the call to every outbound call. The company positions the product as a standard for business calls: recipients see who is calling, from which company, and why, before answering. A central design point is that the recipient does not need to install the Koll app — the identity and call-reason display is said to work when calling any mobile number.
The product's app-side feature set, as described on its Google Play listing, centres on "SmartCard" display of the caller's photo, name, company, phone number and stated call reason, plus built-in messaging and chat with call targets over WhatsApp/RCS and home-screen notifications for reactions and replies. Using the app requires an active Koll business account and licence. The company frames the problem it addresses as unanswered calls from unknown numbers, nuisance sales calls and phone scams, citing over 500 million unwanted calls daily.
Koll is presented as a fully European service: it is headquartered in Salo, in the Varsinais-Suomi region of Finland, produces the service from secure data centres inside the European Union, and states that Koll calls are end-to-end encrypted.
Founding story
Koll Group and its Koll calling app grew out of the founders' aim to fix what they describe as fundamentally broken calling networks, where businesses and public agencies call from unfamiliar numbers and recipients ignore calls because of scam and nuisance-call risk. The founding team cites decades of experience in high-security industries.
Business model
Koll sells a subscription/licence-based business service. Companies place an order, Koll verifies the company's details, the company adds its users, and those users receive invitations to join; app use requires an active Koll business account and licence.
Business subscriptions and per-user licences for company accounts; payment receipts are available to administrators through the Koll portal.
Traction
The Android app listing reports over 1,000 downloads. At the time of the January 2025 investment announcement, the company reported thousands of users in beta testing and planned to launch its enterprise version in spring 2025.
Latest developments
Recent app updates added a SmartCard preview in the user profile, "Today" user reports and admin-accessible payment receipts in the Koll portal, alongside bug fixes to portal reporting for Android calls.

Market position
An early-stage Finnish entrant in verified caller identity and business calling, differentiating on European hosting and security positioning.
Recipients do not need the Koll app for the caller identity and call reason to be displayed; the company emphasises verified caller status, compliance with demanding security requirements, EU-based data centres, end-to-end encrypted calls and a 100% European service.
Technology
SmartCard technology that transmits the caller's photo, name, company, phone number and call reason to the recipient's screen and marks the company as a verified caller, working toward any mobile number without recipient-side app installation. The service also integrates WhatsApp/RCS messaging in-app, is delivered from data centres within the European Union, and the company states that Koll calls are end-to-end encrypted.
Go-to-market
Direct sales with named sales contacts for Finland, Finland and new markets, and DACH, plus a partner sales function; the website offers self-serve ordering, bookable 30-minute meetings and demo calls. Users install the app from mobile app stores after their employer subscribes.
Businesses and professionals making outbound calls to customers — including sales teams — primarily in Finland, the DACH region and other European markets, plus organisations such as agencies, recruiters, healthcare providers and service companies that need their calls answered.
Geography
Headquarters in Salo (Joensuunkatu 7, 24100 Salo), Finland. Sales coverage spans Finland, the DACH region and additional new European markets; service delivery uses data centres within the European Union.
