What Compaya does
Compaya A/S is a privately held Danish SMS communications company founded in 2001 by Martin Schrøder (Sales Director / Partner) and Sonny Larsen (Development Manager / Partner), headquartered at Palægade 4, Copenhagen. The company operates a portfolio of wholly-owned SMS gateway platforms — SMS.dk (modern self-serve gateway with REST API), sms1919.dk (enterprise platform with built-in 2-way SMS via short code 1919 and SMS donation capabilities), CPSMS.dk (legacy platform retained for existing customers), ProSMS (Swedish market gateway), and SendRCS (new Rich Communication Services platform for interactive multimedia messaging). All platforms connect to Nordic telecom operators via high-capacity "large account" SMS routing agreements, and APIs support common programming languages (PHP, .NET, Java, Python, Node.js, Perl) with bearer token authentication, JSON/XML payloads, and webhook delivery reports. The company is GDPR compliant with annual ISAE 3000 attestation, AAA-rated, and hosts data on Danish servers.
The business model is a pure usage-based, pay-as-you-go SMS credit purchase with no subscription fees or setup costs; a free demo with 10 SMS credits serves the self-serve SMB funnel, while enterprise pricing on sms1919 is handled by direct sales. Distribution runs through self-serve online signup (SMS.dk, CPSMS, ProSMS), direct enterprise sales (sms1919), and indirect channels via Zapier and Make.com integrations. Customer concentration is split across a long tail (20,000+ users cited across Denmark, Sweden and other markets, including service businesses such as clinics, hairdressers, and repair shops) and a heavier enterprise/government cohort that includes Copenhagen Airport (Aviator), YouSee, KMD, Energinet, Bilka, PostNord, Unibet, CityContainer, and Aarhus Municipality. The organization runs lean on approximately 8 employees, with no external funding, no disclosed revenue, and a 23-year operating history built on cash flow rather than capital raising.
