Your customers aren’t telling you the truth. Here’s why that matters.

Ask anyone if they’d buy your new product, and they’ll almost always say yes. It’s politeness. It’s social pressure. It’s the gap between what people say and what they do — and that gap is where many great business ideas go to die.

But what if you could test your product, ad, or pricing against thousands of simulated customers before committing to production, printing, or packaging? AI personas designed to behave like real humans — with real preferences, objections, and buying habits?

That’s exactly the bet behind Simile, a synthetic-user startup that just announced a $200 million Series B at a $2 billion valuation — just five months after closing a $100 million Series A led by Index Ventures. It’s one of the fastest rides to unicorn status in recent memory, and it’s not alone in this space.

This isn’t just another Silicon Valley money story. It’s a signal about how market research will work from here on — and that affects how you, as a Malaysian SME owner, should approach your next product launch, marketing campaign, or pricing decision.

TL;DR

Simile builds AI-powered “synthetic users” — simulated human personas used for product and marketing research. The company went from stealth to a $2B valuation in five months, with backers including Bain Capital Ventures and CVS Health Ventures. For Malaysian SMEs, the takeaway is this: the future of market research is becoming faster, more accessible, and far cheaper — and small businesses that start thinking like researchers will have an edge.

What This Means

Simile was founded by Joon Sung Park, a Stanford PhD graduate whose dissertation project, Smallville, involved AI agents living simulated lives — complete with parties. The commercial version of that research is a platform where you can run market research against AI-generated personas instead of recruiting real participants.

Let’s be clear about what synthetic users are not. They are not a full replacement for real customer feedback. TechCrunch itself called Simile’s stated mission of simulating “all eight billion people on earth, accurately and honestly” preposterous — because humans are genuinely unpredictable, guided by both emotion and reason. But you don’t need perfection from a research tool. You need a first-pass reality check.

Think of it like a rough draft for your product decisions. You get directional signals — which segment responds, which messaging resonates, which objections come up — before you spend serious time or resources. TechCrunch compared it to “vibe coding for product mock-ups”: quick, iterative, and good enough to tell you where the real problems are.

“You don’t need to be right about everything before you launch. You need to be wrong cheaply, and early.”

How This Applies to Malaysian SMEs

Here’s the honest truth: most small businesses in Malaysia make product and marketing decisions on gut feel. Maybe you get input from family, a few loyal customers, or a chat group of fellow business owners. That worked when markets moved slowly. But the pace of change — from food trends to e-commerce algorithms — is shrinking the margin for guesswork.

Picture this. You run a small food-and-beverage operation in the Klang Valley. You’re thinking about adding a plant-based menu across three outlets. The old way: test the menu at one outlet, track sales for weeks, and hope the numbers tell you something meaningful. With a synthetic-user platform, you could simulate demand across customer segments — urban professionals, health-conscious families, young Gen Z diners — and get a directional read on which positioning works before you redesign a single menu board or train your kitchen staff.

E-commerce sellers on Shopee and Lazada have an even more immediate use case. Your product title, images, and ad creative are literally your salespeople. A synthetic-user tool could test multiple ad variations against simulated buyer personas to see which copy triggers the most interest — before you commit your monthly advertising allocation. That’s the difference between betting on a hunch and placing a studied bet.

Service-based businesses stand to gain too. A digital marketing agency with ten clients could simulate how different industries would respond to a revised service package. A property agent could test whether tenants respond better to “near MRT” or “5-minute walk to public transit” in listings. A clinic could simulate patient reactions to a new appointment reminder approach. The use cases are only limited by how you think about your customers.

The underlying point is simple: synthetic users lower the floor for market research. Big companies have always had dedicated research budgets and teams. Now, a smaller business can get a useful directional read in hours instead of weeks. That changes who gets to test ideas — which means it changes who gets to win.

Practical Takeaways

• Get familiar with the concept now. You don’t need to buy anything yet, but read up on synthetic users and AI-assisted market research. When a practical tool is available for Malaysian users, you’ll already understand what to look for.
• Audit your last three decisions. Write down your last three product launches or ad campaigns. How many would have improved if you’d tested the idea first? That’s your starting motivation.
• Start with free AI tools. You can already use ChatGPT to roleplay a target customer. Give it context — “you’re a 30-year-old office worker in Petaling Jaya who buys lunch out daily” — and ask for objections to your idea. It’s not Simile-grade, but it builds the testing habit.
• Pair simulated with real. Use simulated feedback to shortlist options, then validate the finalists with real Malaysian customers before major commitments.
• Watch the competitors too. Simile isn’t alone. Aaru, another synthetic-user startup, raised a Series A at a $1 billion valuation in December 2025. Healthy competition means better products and lower barriers for users like you.

The Bigger Picture

This $200 million round tells you more than “AI is hot.” It tells you where market research is heading. In the next few years, simulated customer feedback will become a standard tool — like accounting software or email marketing platforms — that small businesses use without a second thought.

The quality will improve, the barriers will drop, and the gap between what large companies and small businesses know about their customers will narrow. For Malaysian SMEs, that’s genuinely encouraging news. You’re not competing with the big players on research budgets. But you can compete on how quickly you test, learn, and adapt.

The businesses that win the next five years won’t be the ones with the grandest ideas or the loudest marketing. They’ll be the ones that test cheaply, iterate quickly, and listen — to simulated signals early, and to real customers when it counts.
