Macaron

Macaron is a personal AI agent product built by Mindverse (心洲科技), a startup founded by serial entrepreneur Chen Kaijie (陈锴杰). It positions itself as the world's first "personal agent" — designed not for productivity but for life, with deep memory, evolving personality, and the ability to generate functional sub-agents or mini-apps tailored to individual users .

The product launched in August 2025 and quickly gained traction through organic, often controversial, social media presence — including a notable cold start on Xiaohongshu where users created nearly 200,000 custom mini-apps within months . By mid-2026, Macaron reported over 2 million users and more than 100,000 DAU .

Mindverse has pivoted toward framing itself as a model company rather than purely a consumer app. Its technical pitch centers on using LoRA (Low-Rank Adaptation) to deliver "Personal Intelligence" — individualized models that learn and adapt to each user rather than serving everyone with a single generic model . In July 2026, the company released Macaron-V1, which it described as the world's first full-scale personal agent model based on a MoE-LoRA architecture .

The company has raised multiple rounds, including a Pre-A led by Ant Group and co-invested by Sequoia China, totaling over $20 million, with Linear Capital as an early backer from its midreal.ai days . However, its fundraising narrative has drawn sharp skepticism — one critical voice dismissed its LoRA-centric story as "using niche technical jargon to fool stupid investors" and mocked its $200 million valuation as inflated .
