What SMSO does
SMSO is a cloud-based SaaS SMS marketing platform operated by the Romanian private limited company NOOH MEDIA S.R.L., headquartered in Bucharest. The platform enables businesses to send bulk SMS campaigns, transactional notifications, 2FA authentication codes, RCS rich messages, and SMS-based contests, with capabilities including audience segmentation by geography, demographics, subscription type, invoice value, roaming history, and CAEN code. Underlying infrastructure runs on Amazon Web Services, routes through 230+ global mobile operators, and exposes a REST API for programmatic SMS sending, HLR lookup, and number portability verification. The platform serves B2B and B2C communications needs across primary verticals including retail and eCommerce, financial services, and healthcare, with secondary presence in education and government/public sector.
The business model is primarily usage-based: customers purchase SMS credit packages priced between €0.035 and €0.028 per message depending on volume, with billing options including Pay as You Go, Prepay, and Postay. New users receive 100 complimentary SMS credits on registration (freemium). Distribution combines a self-serve web platform, an API-first developer channel, a plugin ecosystem, and direct inside-sales support via phone, email, and chat. Named customers include Bookster, Gral Medical, Bottega Verde, SanoPass, CreditFix, Raureni, Tinmar, and others, predominantly Romanian and European enterprises.
The company is bootstrapped, with no external venture or private equity funding disclosed in the source material, and operates with an 11-50 employee headcount. Recent strategic emphasis has been on RCS messaging capabilities, multi-tier payment flexibility, and platform UX improvements (most recently documented in January 2025). Operational scale is evidenced by a Black Friday 2024 campaign delivering over 1.8 million SMS messages in five days, and by claimed 98% SMS open rates versus email benchmarks. The platform is GDPR-compliant and positions EEA data residency as a trust asset for regulated European buyers.

SMSO competitors and assessment
Company assessmentBroad incumbents
- MessageBird (now Bird): Omnichannel communications platform with SMS, WhatsApp, and email marketing capabilities, originally founded in the Netherlands. Comparable to SMSO on SMS marketing and 2FA, but at larger scale with broader channel portfolio and enterprise sales coverage in European markets.
- Twilio: Global CPaaS leader offering SMS, voice, email, and WhatsApp APIs at scale. Comparable to SMSO on the SMS API / 2FA / programmatic messaging layer, but operates at vastly greater scale with multi-channel breadth and enterprise sales coverage that SMSO cannot match.
- Clickatell: Global SMS and messaging API provider with strong operator coverage and a focus on transactional messaging, 2FA, and marketing use cases. Directly comparable to SMSO's Bulk SMS and 2FA offerings, though with broader geographic and channel reach.
- Sinch: Swedish-headquartered global CPaaS provider with direct operator relationships and a strong SMS / messaging product portfolio. Directly comparable to SMSO on the SMS marketing and 2FA use cases, but with broader channel coverage and deeper enterprise reach across Europe.
- Vonage (Ericsson) API Platform: Global CPaaS platform under Ericsson offering SMS, voice, and messaging APIs with strong telecom-carrier integrations. Overlaps with SMSO on programmable SMS, 2FA, and bulk messaging, but serves a much larger enterprise and developer base globally.
Direct peers
- CM.com: Dutch CPaaS platform offering SMS, WhatsApp Business, RCS, and conversational AI across marketing, customer service, and authentication. Closely comparable to SMSO across the bulk SMS, RCS, and 2FA product surface, and serves overlapping European enterprise customers.

- Infobip: Croatian-headquartered global CPaaS platform with direct operator connections across 200+ countries and a full SMS / RCS / WhatsApp / 2FA stack. Closest regional peer to SMSO on product, scale ambition, and CEE market focus, but with materially larger enterprise footprint and capital base.
- Textmagic: SMS marketing platform for SMBs and enterprises offering bulk SMS, 2-way SMS, integrations, and API access. Closely comparable to SMSO's self-serve SaaS model, freemium onboarding, and SMB-focused pricing, though with broader international customer base.
- Sakari: SMS and messaging platform targeting SMBs with bulk SMS, 2-way messaging, and CRM integrations. Comparable to SMSO on the self-serve SaaS SMS marketing motion, freemium onboarding, and developer-friendly API approach, though operating primarily in North America.
