Simplia is a conversational AI startup I co-founded with an engineer partner. We build AI chatbots and 24/7 phone agents for Spanish small and medium businesses, handling real inbound conversations across WhatsApp, web, and phone, in natural Spanish, at a fraction of the cost of a traditional call center. Our first live client is OficinasYA, a Madrid real estate operator. Their entire WhatsApp inbox and website intake route through Simplia. Real prospects message in, our agent handles the conversation end-to-end, and the OficinasYA team only steps in when the deal is ready to close.
Simplia is a conversational AI startup I co-founded. We build agents that handle inbound conversations for Spanish small and medium businesses, 24 hours a day, across WhatsApp, web chat, and phone, in natural Spanish.
Context
For most Spanish small and medium businesses, “24/7 customer service” has historically meant either an expensive call center or no after-hours service at all. Simplia builds the third option: AI agents that handle inbound conversations in natural Spanish, around the clock. Our first client is OficinasYA, a Madrid-based real estate operator, whose entire customer-facing inbound now routes through Simplia.
Approach
The product runs on n8n for workflow orchestration, with OpenAI and Gemini APIs powering the reasoning layer, ElevenLabs for voice synthesis on phone agents, and a custom layer for Spanish-language intent recognition tuned against real conversation logs from production traffic. The system uses a multi-agent architecture with specialized agents for routing, qualification, scheduling, and handoff, each tuned for its part of the conversation. The architecture is built to swap models quickly: when a better one ships, we test and integrate it within days.
In production
OficinasYA’s entire customer-facing inbound channel (WhatsApp inbox and website intake) now routes through Simplia. The agent has handled 1,114+ production executions in the live deployment so far (verified from n8n analytics, captured at a single point during the rollout). Every inbound prospect (looking for an office, asking about availability, requesting a tour) gets an answer in seconds, day or night.
My role
I’m one of two co-founders. My partner and I both work hands-on across the full stack: product design, conversational design, brand, and the AI infrastructure itself. We share the engineering work: n8n flows, prompt engineering, model integration, voice synthesis configuration, evaluation pipelines. Neither of us hands the “engineering side” to the other; we both ship.
Academic backing
Simplia is the subject of my TFG (Trabajo de Fin de Grado / undergraduate thesis project): specifically a study of conversational AI development models for small business adoption: how to architect, deploy, and validate a multi-channel AI agent system that small businesses can actually use without a technical team of their own.
Public talk
I was selected for the UAX Nova Talent program (UAX × Nova Talent, Spain’s emerging-talent cohort) and presented Simplia on the main stage at the UAX Nova Talent event, speaking for over an hour to the program’s final audience about Simplia, my journey, and what the program meant to it.
Impact
Live in production with real customers right now. OficinasYA’s entire customer-facing inbound channel runs through Simplia: WhatsApp, website, phone. 1,114+ executions across the production WhatsApp flow at a single point captured during rollout, and the system continues to process new conversations as the deployment scales. The product is the subject of my TFG. I’ve presented it on the main stage of UAX Nova Talent. We’re now expanding to additional Spanish SMB clients.
