Antonio Leblanc CTO · 1.5°C EN/PT

Rio de Janeiro · Climate & agentic systems

Intern to CTO in ten months. Today I lead the AI platform protecting 40 million hectares against wildfires.

Policy, community engagement, and ethics matter just as much as the model — that's where I want to keep spending my energy.

01
Pantera
As co-founder and CTO of 1.5°C, I lead the computer vision, satellite imagery, and fire-risk models — with the engineering, ML, and environmental science team that builds them with me.
02
Agents
Eight AI agents in production on Hermes, the open-source agent runtime, on our own servers. One writes the engineering PRs and runs the infrastructure audits; the other seven work inside sales, CS, support, marketing, projects, fire alerts, and leadership, each with a human owner. Every PR the agent writes is reviewed and merged by a person.
03
Beyond CTO
Ran Customer Success, Marketing, Support, and HR at various points — none of it engineering. Fixed what was broken, then handed each off once there was a real owner to take it.
04
ForeFire
Contributor since 2022 to CNRS's open-source wildfire simulator, maintainer since 2025, and co-author on its JOSS paper — reviewing and merging PRs, cutting releases, Dockerization, CI/CD, documentation.
05
Now
Open to CTO or senior technical leadership roles — in climate, govtech, or agentic systems, where the hard part isn't the model but putting it inside an operation where being wrong is expensive.
