Founder of SpielOS · Agent Harness Architect

Shayan Spiel

I spent more than eight years designing growth systems for startups.

Then I spent years building products and agent systems. More than 20 product attempts later, SpielOS is the one that finally brought the work together.

I built SpielOS for companies that know AI should become part of how they work, but do not yet have a reliable structure for roles, instructions, knowledge, tools, human decisions, and quality control. It is the product I needed while repeatedly designing these systems myself.

Before SpielOS, I worked as a marketing strategist and Marketing Director for Iranian startups.

Those outcomes came from designing systems around people, decisions, workflows, customer behavior, and measurement.

The same systems thinking now applies to AI agents: define the workflow, set the boundaries, measure the output.

Twenty products later.

More than 20 product attempts across marketing, automation, AI, content systems, and agent orchestration. Most failed.

The failures

Cost time, focus, and years of work. Some were badly positioned. Some were too early. Some became too complicated.

The lessons

Clarified how complicated products should be structured and where systems usually collapse.

2024

Moving into agent systems.

I discovered that capable models were only one part. The real challenge was everything around them.

LangChain & LangGraph

Full-stack development with agent orchestration frameworks.

Context systems

Multi-agent orchestration with roles, memory, and handoffs.

Evaluation

Quality gates and human judgment in automated systems.

Capable models are only one part of the system. Reliable work also needs roles, boundaries, tools, context, memory, handoffs, evaluation, and human judgment.

Why SpielOS

Where those disciplines
finally became one product.

Most companies know AI should be part of how they work. But they do not have a reliable structure for roles, instructions, knowledge, tools, human decisions, and quality control. SpielOS is the product I needed while repeatedly designing these systems myself.

Not one project in a portfolio

SpielOS is the product my previous work was leading toward. It is not one project in a portfolio. It is the culmination.

Built for companies that need structure
