How TypeSafe came to Eventum for one Senior Product Engineer → and hired all three finalists

Founded by ChatGPT co-inventor Diogo Almeida, TypeSafe emerged from stealth with a $40 million seed round led by DCVC and a bold ambition: make AI judgment a standard building block for software.

Its first model, Jev, works differently from a conventional LLM. It doesn’t generate text. Give it a document and a set of questions, and it returns a yes/no probability, a choice from predefined options, or a score on a rubric... answers your software can use directly.

Jev can evaluate many questions in parallel, with calibrated probabilities that help software decide when to act and when to escalate. The promise is AI decisions fast and affordable enough to embed throughout a product, from routing requests to checking an agent’s next action. Explore how Jev works.

Turning that technology into useful products takes engineers with both technical depth and product judgment. TypeSafe trusted Eventum to help find them.

One planned hire became three

TypeSafe came to Eventum for a Senior Product Engineer who could help turn a new kind of AI into products people could actually use. The hire needed to recognize opportunities in an unfamiliar technology, decide what was worth building, and move quickly from an open-ended idea to working software.

That demanded an unusual combination of product instinct, technical depth, and independence. A promising demo was only the beginning: the engineer also needed to understand its limitations and what it would take to develop it into a reliable product.

Eventum’s role was to identify that combination and put it to the test. We used hands-on technical evaluation to assess how candidates approached ambiguity, made engineering decisions, and took ownership of what they built. We gave TypeSafe concrete evidence of their ability to do the work.

Within two weeks, we delivered three finalists. TypeSafe found the candidates strong enough to expand its original hiring plan and offer roles to all three.

Every offer was accepted. One planned hire became three senior engineers joining TypeSafe’s team.

AI hiring informed by hands-on experience

Eventum builds AI systems as well as helping companies hire the engineers behind them. We understand the decisions these engineers face because we make them in our own work.

Our relationship with TypeSafe reflects that. As an early design partner, we put its technology into production across more than 154,000 job posts. In our benchmark, it delivered 104× lower screening costs than GPT-5.6 Terra. Read the technical case study.

We brought that technical understanding to a search where product judgment and engineering depth both mattered.

Make your next AI hire count

When your next hire will shape how an AI product is built, you need confidence in their judgment. Eventum helps founders and engineering leaders find senior engineers for the work ahead, from exploring a new capability to building reliable production software.
