To Experiment
Brainstorm against source data, test different workflow structures, and recycle previously-built artifacts to design the shape of your use case and discover the information required to get it working your way.
To Engineer
Compose the artifacts required for production-grade behavior in a unified, working surface. Refine the artifacts through intuitive, human-led iteration loops built for fast feedback and high creative throughput.

The transformation infrastructure for aligned AI
Deterministic transformations generate durable artifacts with lineage. Aligned behavior compounds.
Control how systems scale
Pipeline transformations allow you to run prepared behaviors across unlimited inputs in parallel. Capture the data that comes from seeing where they drift and making corrections.
Capture every transformation
Each transformation and iteration is logged with full lineage. Beyond input and output traces, you collect every refinement, constraint, and example that emerges as a product of the process.
Compound judgment over time.
As artifacts accumulate, your organization builds an operational memory, accessible to every workflow, agent, and system you build next.

for governable AI at-scale
Deterministic transformations generate durable artifacts with lineage,
allowing intelligence to compound.
Execute behavior at scale
Pipeline transformations allow you to run prepared behavior across unlimited inputs in parallel. Immediately see the output, edge cases, and failures that help you refine the behavior.
Generate governable assets
Every transformation produces result persists with full lineage. Organize and reuse what you generate as instructions, test sets, examples, and operational datasets.
Compound organizational judgment
As artifacts accumulate, you build your second brain; a central store for the context, derived data, and specifications that make AI work your way.

Control AI behavior across users, teams, and time.

Multi-tenant personalization
AI-powered aps and features that behave differently across users.
Judgment-heavy use cases
AI systems that makes nuanced decisions, where behavior adapts based on context and learned judgment over time
Time-based context updates
AI systems that evolve with changing conditions, where components of behavior need to be dynamically adjusted without full rewrites.
For Developers
Personalized AI features without manual rewrites
Define core behavior once and capture user-specific context automatically, merging both at runtime to deliver personalized behavior at scale.
For Teams
Collaboration without bottlenecks
Separate developer-owned logic from business-owned customization,
so teams can iterate quickly & safely without engineering resources.

Frequently asked questions
What problem does HumanFirst solve?

AI systems need to perform cognitive work—analysis, decisions, reasoning—in ways that align with how your organization or product operates. Most teams lack infrastructure to explicitly define and control that work upstream, so too much gets left to runtime improvisation, leading to variable and error-prone results. 

HumanFirst offers unified infrastructure to govern the artifacts that align AI behavior, and make them available to any system you build.

Who is HumanFirst for?

HumanFirst is for teams building custom AI-powered features, agents, and workflows that need to be consistent and reliable. We help teams turn prototypes into production-grade systems by using operational data and organizational knowledge to shape AI behavior. As you work across multiple models and platforms, HumanFirst helps you standardize the cognitive logic and context that governs AI performance wherever it's deployed.

Why don't existing AI tools solve this problem?

Most AI tools are built for either experimentation or execution, but not the work that connects them. Chat interfaces power discovery, but projects stay locked in conversation threads and don't scale. Orchestration platforms and agents execute behavior, but don't give you enough control to ensure it's aligned.

HumanFirst gives you integrated infrastructure to develop and package reusable behavior for any system you build.

Where does HumanFirst fit in an AI stack?

HumanFirst sits upstream of your agents, workflows, and applications. It's where you define and control how those systems behave.

You can centralize operational data–files, conversations, business intelligence–and use it to discover, refine, and package the artifacts that govern how AI systems perform.

You can also push artifacts created in other systems back to HumanFirst, making it your central store for everything that drives AI behavior.

Packaged behavior can be accessed by any system; invoked dynamically via API, or exported manually as files and skills.

How is HumanFirst different from prompt engineering tools?

Prompt engineering tools optimize individual prompts. HumanFirst is a system of record for all the artifacts that govern AI behavior across your organization—which can include prompts, but also derived datasets, agent skills, organizational knowledge, and more.

We provide data transformation infrastructure to execute behavior at scale in-platform, so you can validate performance against representative data, and prepare datasets for efficient use by agents and workflows.

How is HumanFirst different from vector databases/RAG tools?

Our data infrastructure includes vector search and retrieval capabilities, but HumanFirst isn't a database—it's where you prepare what gets retrieved, validate how it's used, and organize the right data into reusable artifacts that work across your entire AI stack.
