Brazil 2030

The Cost of Delay in the AI Era

With Danilo Naiff, Pedro Castilho, and Ivan M. Franco, I wrote a scenario about what could happen to Brazil by 2030 if we keep putting off decisions about AI. It ends with an open letter anyone can sign.

Work with Tela

At Tela, we help large companies put AI to work in their core operations, where decisions happen at volume and better execution matters to the business.

We combine a platform for building and running AI workflows with a team that works alongside yours. We learn how the operation works, build and test with you, and keep improving it in production as the technology advances.

If your team handles large volumes of documents, cases, or requests, and capacity, turnaround time, or consistency is holding it back, let’s talk about where AI could help. Bring a process you’d like to improve and what a better result would look like.

I lead product at Tela, turning what we learn from enterprise deployments into products that more teams can use.
