Efemosse Sistemas

Based in Argentina, Efemosse Sistemas has been operating since 1999 under a team led by Francisco Mosse, offering support entirely in Spanish. The agency works with businesses that need a single provider for hosting, domains, development and online marketing rather than juggling separate vendors, and its client-facing material emphasizes measurable results over decorative design. Its infrastructure runs on US-based data centers, which the company presents as giving good global response times while keeping commercial and technical support local-language. The service range covers custom web development (front end in HTML5, CSS and JS; back end in PHP and MySQL, with API integrations, Mercado Pago payment gateways and webhooks) alongside packaged hosting plans (M1 through M4) that include SSL, unlimited email accounts, MySQL databases and SEO advisory, priced monthly with discounts for six-month or annual prepayment. Separately, it offers VPS plans on OpenVZ, domain registration and DNS/MX configuration, and email marketing with mass-send templates, open/click statistics and delivery practices such as SPF/DKIM setup and consent handling. Other listed activities include SEO and paid search/social advertising, WordPress builds when suited to the project, e-commerce, booking systems, condominium management (expensas) software, intranets, data migrations and backups, plus training courses and video tutorials for clients managing their own sites.
