Arato Raises $10 Million in Seed Funding to Tackle AI Testing

Arato just raised $10 million. Seed round. And the timing says a lot about where the AI industry actually stands right now, not where the marketing decks say it stands.

Here’s the thing nobody wants to admit out loud: companies are shipping AI products fast, sometimes too fast, without a real way to know how those systems will behave once actual humans start poking at them. Arato’s platform simulates real-world user interactions to help organizations identify failures, assess risks and evaluate AI applications before and after deployment. That’s the whole pitch. Find the problems before your customers do.

The news that Arato raised $10M isn’t just a funding headline. It’s a signal. Investors are betting that testing AI properly, not just building it, is going to be its own category. A big one.

What Is Arato and What Does It Do?

Arato is an Israeli startup developing tools for developers to test and evaluate their artificial intelligence applications. Founded in 2024. Young company. Old problem, in a new wrapper.

Using Arato’s tools, developers can simulate thousands of scenarios using text, image, voice and business data before analyzing the results to spot recurring issues with their apps, identify risks and highlight areas for improvement. So instead of a QA team manually clicking through test cases like it’s 2008, you get a flood of simulated interactions doing the heavy lifting.

And the reason this matters comes down to a basic truth about AI systems: they don’t act like normal software. AI systems are quite unlike traditional applications because they have the potential to generate a much wider range of unpredictable responses based on what the user inputs, making them more difficult to test before they can be safely released. Traditional software does what you tell it. AI does what it wants, more or less, within a probability cloud you can’t fully see. Testing that requires a different mindset entirely. Arato built itself around that gap.

Arato Raises $10 Million in Seed Funding

Let’s be honest, $10 million in seed is a big number for a company barely two years old. But it’s not a fluke.

Arato raised $10M to expand its platform, plain and simple. This is the company’s first real institutional round. Before this, Arato AI had raised a total of $1 million in a pre-seed round. Go from $1 million to $10 million in one jump and you’re talking about a tenfold increase in capital. That doesn’t happen because investors feel generous. It happens because something in the product or the traction convinced them.

The company hasn’t laid out a detailed spending plan publicly. But the broad strokes are obvious: more engineers, faster product development, and the kind of growth that comes with serving more enterprise customers. Arato currently employs 23 people, all based in Israel. That number is going to move.

Who Led the Arato Funding Round?

Here’s the kicker about this round. It’s not just the dollar amount that stands out, it’s who signed the checks.

The round was led by TLV Partners and included participation from Jibe Ventures, Andreessen Horowitz partner and former VMware CEO Raghu Raghuram, and former Intuit CTO Marianna Tessel.

TLV Partners knows enterprise software. That’s not new information to anyone watching Israeli tech. But the individual names here are the interesting part. Raghu Raghuram ran VMware. He knows infrastructure at scale better than almost anyone writing checks today. Marianna Tessel built product and engineering at Intuit for years. These aren’t passive investors hoping for a good outcome. They’re operators who’ve lived through the exact problems Arato is trying to solve. When people like that put their own name behind a seed round, it tends to mean something beyond the spreadsheet.

Meet the Founders Behind Arato

This isn’t a first rodeo. Not even close.

Arato was founded in 2024 by Shahar Erez, CEO, Hilik Paz, CTO, and Tal Salmona, VP of R&D. Three people, one shared history. The three founders have worked together for more than two decades, collaborating over the years at Mercury Interactive and VMware, where they gained experience in software testing, application monitoring, and cloud infrastructure management.

Twenty years. That’s not a buzzword on a pitch deck. That’s two decades of actually building and breaking software together, learning where things fail and why.

And there’s more. Erez and Paz also co-founded Stoke, a workforce management platform that was acquired by Fiverr in 2021 for $95 million. So this is a team that’s already taken a company from zero to a successful exit. Investors notice that. It lowers the perceived risk considerably when founders have done this dance before.

How Does Arato’s AI Testing Platform Work?

So how does this actually work under the hood? It starts with scale. The platform generates thousands of simulated scenarios across text, voice, images and business data, then analyzes the results to identify recurring issues, assess risks and highlight areas requiring improvement.

But generating scenarios is only half the story. The real value shows up in how the results get presented back to teams. The analysis first presents a broad view of recurring trends and behaviors, and then allows teams to drill down into individual conversations or responses to understand what went wrong and how severe the issue is. Zoom out, then zoom in. That’s the rhythm. You see the pattern first, then you go hunt for the specific failure causing it.

It doesn’t stop once something ships either. Arato’s evaluation tools are designed to be used both before deployment and continuously once an AI application reaches production, providing ongoing visibility into how new AI applications perform, how they’re impacting user experiences, and where improvements may be required. So it’s not a one-time gate you pass through before launch. It’s an ongoing watch.

And the results aren’t just theoretical. A global industrial company using an AI assistant for field technicians reduced the time required to validate new software releases from roughly three months to a significantly shorter process, cutting manual effort by about 80% and generating an estimated $5 million in savings over three years. The company wasn’t named. But those numbers are hard to ignore. Three months down to a fraction of that, with real dollars saved.

Why AI Testing Matters for Businesses

The reality is, most companies racing to ship AI features right now have no real answer for what happens when the system gets it wrong. None. That’s not a knock on them, it’s just where the industry is.

CEO Shahar Erez said it plainly: organizations adopting AI know the system won’t meet expectations 100% of the time, and the real question is how often it will fail, in which situations, and what the potential damage could be to users and the business.

It’s not a small concern, either. Organizations get the reassurance of an additional validation layer that helps them understand how new AI applications are likely to perform in the wild and ensure they adhere to the security and regulatory requirements that govern them. Regulation is coming, in one form or another, across most industries touching AI. Having proof that you tested your system thoroughly isn’t optional anymore. It’s becoming table stakes.

Erez didn’t hold back on this point either. He noted that many organizations are launching AI today simply so they can say they have AI, but that approach won’t hold for long. Harsh, maybe. But probably true. Shipping AI for the headline is easy. Shipping AI that actually works under pressure is the hard part. That’s the gap Arato is betting its whole business on.

What’s Next for Arato?

So what happens now? More hiring, almost certainly, beyond the current 23 people. More product work. More enterprise customers, if the early traction with that industrial client is any indication of where things are headed.

It’s worth noting Arato isn’t alone in this space. The market around AI testing and evaluation is getting crowded fast. Straiker, for instance, recently raised $64 million in a Series A round focused on securing enterprise AI agents. Other tools are popping up too, all chasing the same basic need: governance, traceability, confidence that the AI won’t embarrass you in front of a customer.

That competition isn’t necessarily bad news for Arato. If anything, it confirms investors see this as a real, durable category rather than a passing trend tied to one news cycle.

For now, Arato raised $10M, and that gives the company real runway. Backed by operators who’ve actually built and scaled infrastructure businesses before, not just people writing checks from the sidelines. As more companies push AI into business-critical roles, the kind of testing Arato offers might stop being a nice-to-have. It might just become the cost of doing business.
