What Sooyoos does

Sooyoos SARL is a privately held, bootstrapped Paris-based digital agency (founded circa 2012, RCS Paris 504 673 401) operating from 11 rue Oberkampf in the 11th arrondissement. The firm designs and develops bespoke web and mobile applications for mid-market and large enterprises, with a stated headcount of 22 digital experts and a cumulative 314 projects delivered across verticals such as healthcare, finance, retail, public-sector research, hospitality, construction, and infrastructure. Its service portfolio spans MVP development, scalable architecture, business and sector-specific applications, system and API integration, intelligent workflow automation, CMS implementations (Strapi headless and WordPress), and multilingual/internationalization solutions, built primarily on Symfony, React/React Native, Next.js, Node.js, TypeScript, PostgreSQL, and AWS.

The company has built its go-to-market around regulated industries (healthcare, finance, pharma) where applications must comply with RGPD, ISO 27001, HDS, PCI-DSS, SOX, and HIPAA by design; named enterprise clients include Roche (diabetes platform Phil Web), Semmaris/Marché de Rungis, Nespresso, Acadomia, Freyssinet, Dassault Systèmes, Sanef, Pierre Frey, Berger Levrault, Pernod Ricard, and Prestashop. It monetizes through three streams: quote-based custom development (professional services), tiered recurring TMA subscriptions (SECURE at €1,190/month, GROWTH at €2,750/month, STRATEGIC PARTNER custom), and packaged Custom AI Agents engagements (Starter €1,000, Complet €5,000, Sur mesure custom) — with 85% of clients reportedly retaining TMA services post-delivery.

A dedicated AI Agents line, integrated as a core offering, deploys autonomous agents, RAG-based knowledge retrieval, generative content, NLP, computer vision (notably for the Skin AnalysIA diagnostic kiosk), and workflow automation on sovereign, France-hosted infrastructure, distinguishing the firm from generic AI tool resellers. Distribution is direct-enterprise via website-driven lead generation and quote-based pricing, with a technical blog and case studies as the primary content-marketing channel; partnerships include AWS (certified since 2022) and hosting provider Scaleway. The company holds €492,588 in registered capital, is privately owned by its founders (Serge Soudoplatoff as co-founder and advisor, Maximilien Wecxsteen as Directeur de publication), and reports no institutional investment, M&A activity, or parent-company affiliation.
