What Sleed does

Sleed is a Greek digital, creative, and technology agency founded in 2010 and headquartered in Peristeri (Athens), Greece, with a secondary office on Leoforos Athinon in Athens. The company provides integrated digital marketing, e-commerce development, and AI solutions to enterprise and mid-market clients, primarily across Greece, the EU, and select international markets. It serves a diverse portfolio of more than 50 named clients spanning retail, fashion, sports, FMCG, pharmaceutical, financial services, automotive, hospitality, and media verticals, with enterprise logos including Nike, Lacoste, ASICS, Barilla, Roche, AstraZeneca, MSD, Schneider Electric, Colgate, Palmolive, Bank of Cyprus, Coffee Island, Eurolife FFH, Europcar, Würth, and GAP, alongside mid-market Greek brands such as Spitishop, Cosmos Sport, Politeia, and Sfakianakis Group. The agency employs 150+ staff and is privately held as Sleed S.A., with a strategic investment from The Olympia Group made via its PCP investment arm in November 2023.

Sleed's core offering is structured around five service pillars: Digital & Data (performance media buying across Google, Meta, TikTok, programmatic, and native channels; SEO and Generative Engine Optimization; web analytics and tracking via GA4 and GTM); Digital First Creative (platform-optimized creative production for performance and brand campaigns); CRM & Marketing Automations (strategy and execution across email, SMS, segmentation, RFM analysis, and AI personalization using certified expertise in Klaviyo, Mailchimp, ContactPigeon, and Moosend); Website & E-commerce Development (build, optimize, and maintain Shopify, WooCommerce, Magento, and custom platforms); and Hosting (enterprise-grade infrastructure for news portals and e-commerce systems). The company also distributes a proprietary AI product suite comprising ONEgpt (a unified AI workspace aggregating ChatGPT, Claude, Gemini, and Grok with privacy controls and per-seat pricing at €15/user/month), AI UX Lab (behavioral simulation for e-commerce conversion optimization), and AI Fashion Pack (AI-generated fashion imagery and virtual try-ons) — all developed by its subsidiary HappyOnline following Sleed's 2024 strategic investment.

The business operates a sales-led go-to-market model with direct enterprise engagement via website contact, phone (+30 210 577 0411), and email ([email protected]), supplemented by long-tenure strategic partnerships with Google (Premier Partner since 2011), Meta (Business Partner since 2020), and TikTok (Marketing Partner since 2022). Sleed has accumulated more than 300 industry awards across its 15-year history, including five consecutive years as E-Business Agency of the Year at the E-volution Awards and recognition at the Effie Awards. The company maintains an in-house talent development program (Sleed Academy Marathon, 7 editions, 100+ trained) and a thought leadership platform including the "Sleed the Way" podcast (45+ episodes). Revenue is not publicly disclosed.
