01 / Aelven mission

The next frontier of human data.

Aelven is an agent-native human data company creating new classes of human data at exceptional quality and scale.

With intelligent tooling, we empower experts to produce rich, consistent data that captures judgment, context, correction, and intent across proactive collection initiatives and custom data programs for AI labs.

Our engineering-led model means every data program gets purpose-built interfaces, instrumentation, and quality loops tailored to specific data needs.

Together, these systems form the connective tissue through which people and intelligent machines learn from one another.

02 / About Aelven

Experience from across the AI data ecosystem.

Aelven is built by a team with experience at frontier AI labs, Y Combinator, and established human data companies.

We understand the work from both sides: what advanced AI teams need, and what it takes to turn human expertise into reliable data systems at scale.

03 / Intelligent tooling

A new production model.

Aelven focuses expert attention where it matters most.

Our agent-native tooling surrounds experts with the systems needed to create, review, refine, and quality-check high-context data with speed and consistency.

Each task strengthens the workflows, standards, and interfaces behind the next one.

Exceptional people, intelligent systems, and compounding quality loops are at the core of the Aelven production model.

Aelven production model: capture high-context data, experts and agents input, deliver high-quality data, and refine tooling.

04 / Data catalog

New classes of human data.

Aelven proactively creates human data that has never been captured before.

We capture workflows and permissioned life-context data in real-world environments, surfacing the hidden structure inside human behavior and transforming it into datasets frontier AI systems can learn from.

Future AI systems will need to understand people across time, goals, tools, environments, and actions. Aelven is building the data layer to support that future.
