American dating startup Ditto aims to kill Tinder! Not "swipe left or right," but claims AI simulates thousands of dates before matching

Founded by UC Berkeley student Allen Wang and Eric Liu, the AI campus dating service Ditto completed a $9.2 million seed round this February. The round was led by Peak XV Partners (formerly Sequoia India), with participation from Gradient, an AI venture arm of Google. Ditto’s core selling point is “zero swiping” and “zero app”: AI builds virtual personas for users and recommends matches only after simulating more than 1,000 dating scenarios. Its matching rate is 69%, far higher than the 25% typical of traditional dating apps. It currently has 42,000 college students using it.

• Core technology: AI constructs virtual personas for users and simulates more than 1,000 dating scenarios before recommending matches, achieving a 69% match rate

“Help your roommate find a girlfriend before graduation” was the original motivation for Allen Wang and Eric Liu to start their company. Wang, recalling an interview with KTVU Fox 2, said that he and his friends spent hours every day swiping on dating apps, yet they could hardly ever find a girl to go on an actual date with.

That frustration ultimately led to Ditto, a new campus dating startup that promises to “kill Tinder with AI.” The two later took a leave of absence from Berkeley to work on it full-time. It officially launched in 2025, and in February 2026 it raised a $9.2 million seed round. A dorm-room joke turned into an AI company backed by Peak XV Partners (formerly Sequoia India).

AI simulates “date a thousand times first”

Ditto’s way of working is unlike any dating app you’ve seen. First, there’s no app—everything happens on MacOS through iMessage. Users chat with an AI chatbot via a link, answering three layers of questions: basic information, deep preferences (including deal-breakers, beliefs, and dating activity preferences), and even the option to upload celebrity photos of their “ideal type” for the AI to reference.

Next comes the core: the system builds a “virtual persona model” for each user, then lets two virtual personas run more than 1,000 simulated dating scenarios. This isn’t just matching based on superficial interest tags; it simulates first-impression reactions, conversational flow, and alignment on values. Behind it is a multi-agent LLM system, with AI roles such as an analysis expert, a matching expert, and a scheduling expert, working together through task division and collaboration.

Finally, every Wednesday you receive a match recommendation, including photos, basic information, date time and location, and even AI-generated conversation opening lines. Only after both sides confirm do they exchange phone numbers—before that, you can’t reach each other at all.

According to Ditto’s official information, the match rate is 69%, far above the roughly 25% of traditional swipe apps. The conversion rate from matching to an actual date is 20%. Each simulated date isn’t real, but Ditto is betting that 1,000 AI dates can filter out most of the deal-breakers in real-life dating.

From UCSD sorority group chats to $9.2 million

Ditto’s breakthrough came from UC San Diego. After launching in 2025, the product spread rapidly through sorority group chats, and then expanded to Berkeley, USC, UCLA, and UC Davis. This year, in March, it moved beyond California and entered Arizona State University.

All members register using .edu email addresses. Among the 42,000 users, more than 25% come from word-of-mouth referrals, with no paid marketing.

Funding followed: in February 2026, Ditto completed its $9.2 million seed round, led by Peak XV Partners, with participation from Gradient, Scribble Ventures, Alumni Ventures, and Llama Venture—four investors including Google’s AI venture Gradient—bringing total funding to $9.5 million.

Gradient partner Vig Sachidananda commented: “Ditto uses AI in a creative way to build an online dating experience that’s similar to a real matchmaking service.”

The company is currently in its early stage with no charges and no revenue yet, prioritizing user growth. In addition to dating matches, Ditto has partnered with the anonymous social platform Yik Yak to launch friendship matching quizzes, and it plans to expand nationwide in 2026. In the future, it even wants to extend beyond dating into job matching and friendship socializing.

Tinder’s “swiping era” is falling apart

Ditto’s timing is delicate. Match Group (Tinder’s parent company) has seen seven consecutive quarters of decline in paid users, while Bumble cut 30% of staff and its stock fell by 30%. Surveys show that 79% of Gen Z and 80% of Millennials say they’re exhausted by endless swiping and being left on read after matching. In the UK alone, 1.4 million people left dating apps between 2023 and 2024.

Traditional dating apps have a fundamental contradiction: the less users are able to find someone they like, the more time they spend on the platform—making the platform earn more money. Ditto is trying to reverse this logic, changing the success metric from “time spent” to “number of real dates.”

But there’s plenty of skepticism, too. ASU communications professor Liesel Sharabi told the school paper bluntly: “At present, no algorithm can immediately identify your ideal partner.” Some users also complain that the dating activities recommended by AI are “rather mediocre”—coffee, browsing record stores, dinner, and movie outings—nothing like the level AI should be able to deliver.

What’s even more interesting is that two 16-year-old high school students used AI-assisted programming to rebuild Ditto’s core functionality within just a few days, suggesting that the product’s technological moat may not be as deep as people imagine. However, later the two were recruited by Ditto. After all, no one knows how Ditto’s “AI black box” really runs—maybe Berkeley’s startup reputation is just more convincing, hehe.

Common Questions

How does Ditto’s AI matching mechanism work?

Ditto builds a virtual persona model for each user. Using an LLM multi-agent system, it simulates more than 1,000 dating scenarios, then recommends matches only after evaluating first impressions, conversational flow, and value alignment. The entire process is completed on iMessage—no need to download an app.

What is Ditto’s current funding size and user base?

In February 2026, Ditto completed a $9.2 million seed round led by Peak XV Partners, with participation from Google Gradient. Total funding reached $9.5 million. It covers 6 US universities and has 42,000 users; it is currently free to use.
