Stak Enterprise
Control layer for AI-powered operations
Stak turns complex operations into systems teams can control with confidence. Models execute. Humans verify critical decisions. Every step stays visible and auditable at scale.
Publicly introduced in 2019, Stak arrived early in a new wave of workflow platforms, with human verification built in from the start.

The Challenge
Making complex automation controllable
Enterprise teams won’t hand critical operations to a black box. They need to inspect decisions, override exceptions, and produce outputs that hold up under scrutiny.
Automation without control doesn’t scale. That constraint shaped every decision in this system.
01.
Workflows remain readable as complexity grows.
02.
Every decision and output stays visible and traceable.
03.
Critical steps require verification before execution.
04.
Human reviewers stay aligned through clear feedback.
System model
AI handles speed. Human review enforces trust. Every workflow produces outputs that can be traced back to the source.
01 — Workflow Editor
The engine of the platform
Stak's workflow editor is where teams build production workflows by combining AI steps, human verification, and reusable automation patterns.
Drag, drop, and edit in one view
Solves fragmented editing. Teams drag steps onto the canvas and configure them in a single, consistent side panel. The workflow stays visible while decisions are made.
Work fast, stay on the canvas
Reduces context switching during flow building. Quick actions on the node and a searchable command palette let teams build and refine workflows without leaving the canvas.
Nested Workflows
A single input can generate dozens of parallel tasks. Each runs its own workflow, gets validated, and returns a result—combined into one consistent output.
Human decisions stay in the loop
Human review is a first-class node you place deliberately. You decide where certainty matters. The audit trail reflects your intent, not the system's assumptions.
Describe the task, expected output, and constraints.
The system generates a structured workflow.
Edit every generated step
Workflows can be inspected, adjusted, and extended.
Automation stays flexible and under control.
02 — Admin Console
Monitor, inspect, intervene
Stak processes workflows across legal, transcription, insurance, and software operations. Teams need to understand what is happening, not just that something ran.
Track executions in real time
Filter runs, inspect statuses, and intervene when needed. Every action stays connected to its context.
One system, different perspectives
Interfaces adapt to roles without fragmenting the platform. Teams operate differently but stay aligned on the same system.
Proven in production
Legal review workflow
Users upload case documents and questions. Stak returns a structured Excel or CSV answer sheet with source links, making every output easier to review, verify, and audit.
03 — Design System
A system built to extend
Components encode behavior, states, and verification.
The same system applies across workflows, dashboards, and every interface.
$60 per hour at 95% accuracy becomes $1.25 at 99%+
30 minutes and $35 per task becomes under 2 minutes and under $1
85% faster test generation with 40% lower cost
Moved workflow building from modal based setup to persistent configuration in context
Made human verification explicit instead of hiding it behind system exceptions
Unified AI, human, and logic steps into a clearer shared node system
Clarified the surfaces for monitoring runs, resolving exceptions, and auditing outputs
