About Blocks
A platform for workflows that require both AI speed and human accountability
Blocks is an agentic workflow platform built for operations, compliance, and product teams. Every workflow has a clear owner, every decision is logged, and the outcome is traceable — from trigger to close.
Where Blocks started
We started building Blocks in 2024 after working on process tooling for operations teams and noticing that existing automation platforms treated human decisions as edge cases rather than core workflow participants. Zapier, Make, and similar tools are built for linear data pipelines — not for processes that require a legal reviewer, a manager sign-off, or a risk assessment before the next step can proceed.
That gap — between AI execution speed and human accountability — is what Blocks is designed to close. We built the workflow execution engine, the human approval routing layer, and the audit trail as first-class features, not afterthoughts. Blocks launched publicly in June 2025 and is entirely bootstrapped.
AI outputs need human checkpoints
An AI decision without a human in the loop is a liability. Every Blocks workflow has a designated place for a person to approve, reject, or escalate before execution continues.
Every decision should be reviewable
Audit trails are not a compliance afterthought. They are a product feature. Blocks captures every automated output and human decision in a persistent, searchable log.
Orchestration beats point integrations
Connecting two systems is easy. Orchestrating a five-step process across four systems — with conditional routing, fallback logic, and a deadline tracker — is the actual problem we solve.

What we care about
These are not values we chose because they look good on a careers page. They are the things we argue about in product reviews.
Transparency over magic
Every workflow step in Blocks is inspectable. We do not hide complexity behind black-box automation. Users should always be able to see what happened and why.
Humans stay in the loop
We believe AI agents should extend human judgment, not replace it. Our product is designed so humans can review, override, and take accountability for automated decisions.
Boring infrastructure, interesting product
Blocks runs on reliable, battle-tested infrastructure. We spend our creativity on product experience, not on re-inventing the underlying plumbing.
Prove it in production
We ship to real customers early and iterate based on what they actually do, not what they say in interviews. Speed of learning beats precision of planning.
Debt is a choice, not a default
We take on technical debt intentionally. When we incur it, we write it down. The goal is a codebase that stays fast to change as the product grows.
Teams, not heroes
Blocks is a focused team with high standards. We win or lose together. We write documentation, share context, and make sure nobody is the single point of failure for anything important.
We are hiring.
Work on a platform where workflows, human approvals, and LLM orchestration are first-class design problems.
