Upstream

What Upstream does

Upstream is a mobile marketing technology company that builds and operates the Grow platform — a cloud-based marketing automation suite for customer acquisition, engagement, and conversion across mobile-first channels. Founded in Athens in 2001 by Marco Veremis and Alex Vratskides and now headquartered in London, the company serves mobile network operators (MNOs) and e-commerce/retail brands across more than 22 countries in Latin America, Africa, the Middle East, and Southeast Asia. Its proprietary technology stack includes Secure-D (real-time anti-fraud), a patented Mobile Identity solution for cross-device ID resolution, Zero-D (zero-rated ad-funded channel), and channel orchestration across SMS, MMS, RCS, WhatsApp, Viber, push, email, social, and operator web channels, with event-triggered automation and audience management capabilities.

Upstream monetizes through enterprise subscriptions to the Grow platform combined with performance-based managed services, delivering customer acquisition, CRM campaigns, VAS promotion, and cart-recovery programs. Marquee customers include Vivo, MTN South Africa, TIM Brasil, dtac, Claro, and Vodacom on the MNO side, alongside e-commerce brands such as Sem Parar, AMOBELEZA, Frutifica, and Jogê, with reported customer outcomes including 174% YoY subscription growth for dtac and ROIs ranging from 11x to 57x for retail clients. The company claims 1.2 billion consumer reach, 370+ active advertisers, 3.1 billion monthly interactions, and 4,000+ executed campaigns, supported by approximately 300 employees across seven offices.

In July 2025, Upstream was acquired by Intersel, a global investor specializing in telecom and emerging markets, ending Actis's decade as primary investor. The acquisition was followed by partnerships with Škoda (cybersecurity/automotive, January 2026) and LALIGA/Vodacom (sports content, South Africa). Earlier financing includes a €14 million debt facility from the National Bank of Greece in December 2022 and historical equity rounds from Actis (2014/2018), the European Investment Bank, and TLcom Capital Partners.

Direct peers

• Twilio: Twilio's Customer Engagement Platform offers programmable SMS, MMS, WhatsApp, RCS and marketing-automation APIs targeting enterprises globally. Like Upstream, Twilio powers mobile-messaging-driven customer acquisition and engagement at scale, though Twilio serves a broader developer/CPaaS market beyond Upstream's MNO-channel niche.
• Infobip: Infobip is a global CPaaS and mobile-messaging platform with deep telco operator relationships, an omnichannel campaign suite, and direct-carrier-billing/identity products that overlap with Upstream's Grow, Secure-D and Mobile Identity offerings across emerging markets.
• Sinch: Sinch provides cloud communications and mobile customer-engagement APIs (SMS, RCS, WhatsApp, voice) with significant telecom-operator integrations. Its messaging-platform-plus-marketing-automation stack competes head-on with Upstream's Grow platform, particularly for telco and enterprise customers.
• MessageBird (Bird): Bird (formerly MessageBird) is an Amsterdam-based omnichannel CPaaS marketing-automation platform with Flow Builder, SMS/RCS/WhatsApp channels and AI-driven segmentation — directly comparable to Upstream's Grow orchestration and event-triggered campaign capabilities.
• CM.com: CM.com is a European CPaaS and mobile-commerce platform offering SMS/RCS/WhatsApp messaging, marketing automation, payment processing and customer-data platform capabilities. It is a direct peer in mobile-marketing automation for retail/e-commerce and telco customers across multiple regions.
• LINK Mobility: LINK Mobility is a Nordic/European mobile-messaging and CPaaS provider offering SMS, RCS, WhatsApp business messaging and marketing-automation tools to enterprise and telecom customers — closely comparable to Upstream's enterprise-mobile-marketing positioning.
• Braze: Braze is a customer-engagement platform for multichannel marketing (SMS, push, email, in-app, RCS) used by consumer brands for personalized lifecycle campaigns. Its orchestration and segmentation capabilities overlap directly with Upstream's Grow platform for e-commerce and digital-service customers.

Regional players

• Zenvia: Zenvia is a Brazil-headquartered CPaaS and conversational-marketing platform dominant in Latin America — overlapping directly with Upstream's strong Brazilian telco and e-commerce footprint (Vivo, TIM Brasil, Sem Parar) while primarily serving a different geography at greater depth.

Broad incumbents

• HubSpot: HubSpot's Marketing Hub includes SMS, email, automation, audience segmentation and analytics — overlapping with Upstream's Grow platform but serving a much broader SMB-to-enterprise market without Upstream's telco-channel depth or emerging-markets specialization.
• Salesforce Marketing Cloud: Salesforce Marketing Cloud is an enterprise marketing-automation suite covering SMS/MMS (via MobileConnect), email, social, advertising and customer-journey orchestration — comparable in functional scope to Upstream's Grow but positioned as a horizontal enterprise stack rather than an MNO-channel specialist.
