What SMS Proxima does

SMS Proxima is a French self-serve SaaS platform that enables businesses to send professional SMS campaigns, transactional notifications, automated reminders, and rich SMS-with-landing-page messages, plus to rent RGPD-compliant opt-in contact files for new customer acquisition. The underlying technology is a cloud-based SMS delivery stack with premium operator routing, a REST JSON API secured via Bearer tokens, a HMAC-signed webhook event system for delivery receipts and STOP responses, sandbox testing, idempotency keys, and an official open-source PHP SDK. A native PrestaShop module extends the platform into e-commerce merchants, and a Progressive sending engine allows campaigns to be spread across defined time windows to avoid receiver overload.

The company serves a horizontal mix of French small and mid-sized businesses — boutiques, restaurants, beauty salons, garages, opticians, real estate agencies, hotels, and healthcare professionals — alongside a smaller set of enterprise and public-sector accounts (including Superdry, Eiffage, and Ville de Luc-sur-Orbieu). Its go-to-market combines product-led self-serve registration with optional human-assisted campaign management (Formula Zen at +10 EUR HT per campaign) and an invitation-only Premium subscription for high-volume clients.

SMS Proxima is structured as a SAS (Société par Actions Simplifiée), is bootstrapped and founder-owned by Laurent Martinolle, and is listed as an Activateur France Num on the French government's small business digitalization portal. All alphanumeric sender names are registered through AF2M for compliance with French Business Messaging rules. Revenue is not publicly disclosed; the company monetizes via usage-based SMS credit purchases with no subscription or commitment, and credits never expire.
