Can a startup with no funding build their dream chip?

Not a rhetorical question. A real one.

Every plan, every execution, every milestone — all revolves around traditional sign-off tools. Tools that cost more than your entire runway. Tools that decide if your silicon lives or dies.

What if sign-off tool usage is limited to certain months? What if you could iterate freely, fail cheaply, and only pay when it truly matters?

That question changed everything for us.

What the industry knows but rarely admits

Everyone is building in-house EDA tools. They're not myths anymore — but they aren't public either.

When export restrictions hit advanced EDA tools, it proved something important: EDA access is geopolitical leverage.

Hyperscalers build private tooling. Serious chip teams demand local control. Not because disaster is imminent — but because dependency is still dependency.

Sovereign capability always wins long-term.

This isn't ambition. This is necessity.

We are a simple startup that realized one thing:

We cannot build a chip without deep pockets.

Government programs may provide tools. Subsidies may help. But long-term, the backbone of semiconductor capability is EDA. Without it, you're renting your own ambition.

Our story — one year in, years ahead

We started with a question: What if we didn't wait for funding to start building?

One year later:

  • We built a working demo of the flow
  • We integrated OSS tools where commercial was unaffordable
  • We filled gaps with our own tools where OSS fell short
  • We are now executing on an actual SoC

It's not perfect. We have challenges. Real ones.

But here's what we learned: If this is our problem, it's every startup's problem.

What does it take?

Not a replacement for tools. Not a magic button.

An intelligence that lives inside the chip flow. That observes RTL → simulation → regression → signoff. That remembers why decisions were made. That learns patterns within the same project.

Big EDA giants already do this. They have:

  • Decades of internal bug databases
  • Regression histories across thousands of projects
  • Jira + waiver + ECO + signoff correlations
  • ML systems that predict root causes — not from theory, but from pattern memory

Startups have none of this. Every team starts from zero. Every bug is discovered fresh. Every pattern is learned the hard way.

That's why we need our own intelligence — not to match their decades, but to stop losing ours.

Not to predict every bug — but to answer:

"Have we seen this failure pattern before?"

That alone saves months.

The future advantage

It won't come from smarter tools.

It will come from teams that remember better.

Our Approach

We're building systems that think about specifications the way engineers do.

We enhance open-source tools with an intelligence layer. We bridge the gap between
open-source capabilities and commercial tool requirements for comprehensive signoff.

Walk-in ones, walk-in zeros
