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?

HumanFirst closes the gap between using AI and reliably incorporating AI into real work. Today valuable data lives across tools, but turning that data into consistent, high-quality AI behavior is manual, fragile, and irreproducible.

HumanFirst is a dedicated environment where organizations can transform  data into governed, reusable AI behaviors. Our infrastructure enables product teams to ship differentiated AI features faster, professional services teams to quickly discover and deploy customer-specific solutions, and enterprise customers to safely customize and extend AI capabilities themselves as a scalable, evolving layer of organizational intelligence.

Who is HumanFirst for?

HumanFirst is for stakeholders building and deploying AI in products and workflows — product teams creating differentiated AI features; professional services teams delivering customized solutions with customer data; enterprise power-users who need to adapt and extend AI capabilities safely over time.

We're built for teams moving from experimentation to reliable AI outcomes. We help those teams ground models in real data, iterate rapidly, govern quality, and make AI capabilities reusable across users, customers, and applications.

Why don't existing AI tools solve this problem?

Existing AI tools are designed either for using AI or for engineering models, but not for systematically building and managing reusable AI behavior grounded in real organizational data.

Chat interfaces and copilots produce outputs that don’t persist or evolve, while developer frameworks and data pipelines require heavy engineering. Knowledge is lost, behavior is largely ungoverned, and customization is fragile and expensive; teams struggle to move from experimentation to reliable deployment.

HumanFirst provides a dedicated layer where AI instructions, context, and transformations are iterated on, versioned, governed, and operationalized as durable capabilities across products and teams.

Where does HumanFirst fit in an AI stack?

HumanFirst sits between foundation models and end-user applications as the AI behavior and control layer where organizational data, instructions, and expertise are assembled into reusable, governed AI capabilities before they’re executed inside products.

Models provide raw intelligence, applications provide user experiences, and HumanFirst manages how AI behaves, enabling teams to design, test, refine, and version the instructions, context, and transformations that turn generic models into reliable, domain-specific systems.

In your AI stack, HumanFirst is the system of record and development environment for AI behavior, bridging experimentation and production so AI capabilities can be consistently deployed, customized, and improved.

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.
