About Marcos

¿Quieres integrar IA en tu negocio sin acabar con un piloto que se queda en el cajón? Te ayudo a diseñar e implementar soluciones de inteligencia artificial que generan resultados medibles desde las primeras semanas.

Soy Marcos, fundador de Maistik Studio. Llevo más de 20 años desarrollando software y, en los últimos años, he liderado proyectos de IA para empresas como Iryo, Lab Rubio, Forus, Bounsel, Fibsen, entre otros muchos, ayudándoles a convertir la IA en una ventaja competitiva real, no en una demo bonita que nadie usa.

¿En qué podemos ayudarte?
  • Desarrollo de agentes IA y Business Copilots a medida
  • Integración de LLMs (OpenAI, Anthropic, modelos open source) en tus productos y procesos
  • Desarrollo de modelos complejos y fine-tunning the LLMs.
  • Automatización inteligente de procesos internos: atención al cliente, gestión documental, ventas, operaciones
  • Consultoría estratégica IA: del descubrimiento al roadmap técnico
  • MVPs y prototipos funcionales en tiempo récord
  • Arquitectura escalable, segura y lista para producción

¿Qué nos diferencia?
  • Enfoque técnico con visión de negocio: no construyo IA por moda, sino para resolver problemas concretos y rentables
  • Comunicación constante y proactiva durante todo el proyecto
  • Experiencia probada en SaaS, LegalTech, HealthTech, FinTech, TravelTech y herramientas de productividad
  • Studio propio: puedo escalar de freelance a equipo completo según lo que necesites
Si tienes una idea, un problema operativo que crees que la IA puede resolver, o buscas un partner técnico que entienda tanto el código como el negocio, hablemos. La primera llamada siempre es para entender tu reto y validar si encajamos.
