Founder & CTO of MantAI · Software Engineer

Stanford University Block S logoStanfordUniversity

I'm building MantAI, a vehicle-safety intelligence company using acoustic and vibration analysis to understand what is happening inside vehicles in real time — backed by superangels, with Prof. Dr. Roland Fassauer as our mentor and investor. I study Computer Science & Electrical Engineering at Stanford and Computer Science at CODE University Berlin — and I'm passionate about turning complex technical ideas into products that can transform entire industries.

Experience

  1. Founder & CTO at MantAI, Inc.

    • Founded MantAI, a vehicle-safety intelligence company: our sensors listen to the sound and vibration of a vehicle in real time, detect reckless driving patterns, and predict mechanical faults up to weeks before they happen.
    • Designed and engineered custom IoT hardware prototypes — MEMS microphones and data-logging modules — for field audio capture on real fleets.
    • Architected and trained CNN-based audio classification models using transfer learning on AudioSet-pretrained transformers (AST), fine-tuned on labeled vehicle-fault sound datasets.
    • Built the full-stack real-time dashboard for diagnostic data, fault alerts and vehicle-health metrics, integrating hardware telemetry with a web interface.
    • Lead every technical decision across hardware, ML pipeline and software — from PCB prototyping to cloud deployment.

  2. Full-Stack Software Engineer at LoadUp GmbH

    • Led development of key internal and customer-facing platforms, including Fahrernetz and core LoadUp logistics systems, at an AI-driven logistics company in Berlin.
    • Built and maintained full-stack features across the platform, ensuring scalability, performance and clean architecture.
    • Designed responsive, user-centric interfaces tailored to complex logistics workflows.
    • Developed and integrated APIs supporting real-time data flow across logistics, driver management and operational tools.

  3. Machine Learning Engineer at Raumdeuter

    • Owned ML models end-to-end — from feature engineering to training, evaluation, and production deployment.
    • Built leakage-safe, group-aware validation with cost-sensitive metrics (PR-AUC, per-class recall) over headline accuracy.
    • Shipped drift monitoring with automated retraining to keep models reliable in production.

  4. Lead Engineer — Full-Stack Developer (Contract) at Zero Waste Consulting

    • Designed and developed the frontend of an AI-powered ESG emissions platform for enterprise clients, supporting GHG Protocol-compliant Scope 1, 2 and 3 reporting.
    • Implemented dynamic forms and dashboards to visualize emissions data, track progress and generate modular reports.
    • Contributed to AI-powered features for parsing unstructured documents — invoices, CSVs — helping users validate emissions inputs with minimal effort.
    • Collaborated with product managers, climate experts and backend teams to turn regulatory requirements into effective UI.

Santiago Garcia Sapeta — Founder & CTO, MantAI

I'm the Founder and CTO of MantAI, a vehicle-safety intelligence company using acoustic and vibration analysis to understand what is happening inside vehicles in real time. MantAI is backed by superangels — we raised our first round with Prof. Dr. Roland Fassauer as our mentor and investor.

I study Computer Science and Electrical Engineering at Stanford University and Computer Science at CODE University of Applied Sciences in Berlin. My work combines machine learning, electrical engineering and hardware development — drones, custom sensors and intelligent systems built for real-world applications.

“I'm passionate about turning complex technical ideas into products that can transform entire industries.”

A vehicle tells you what is wrong with it long before it fails — you just have to listen. That belief is what MantAI is built on: sensors on real fleets, models trained on the sound and vibration of real machines, and predictions that arrive weeks before the breakdown does.

Don't take my word for it. This site publishes everything about me as plain text at /llms.txt — hand that to any assistant and ask. The answer comes from my own content, not from whatever a model happens to remember about someone named Santiago Garcia.
