Lark

Executive Summary

Lark is ByteDance's global enterprise collaboration platform — a genuinely well-built, AI-native productivity superapp with verified ARR growing from $100M (2022) to a targeted $300M+ (2024) at 50% year-on-year. The product is real, the market is large ($36B in 2024, growing to $57B by 2030), and the traction in APAC is credible. But the investment thesis breaks down on a single, structural fact: Lark was explicitly named by the US Department of Justice in 2024 federal court filings as the instrument through which TikTok employees transmitted sensitive US user PII to ByteDance servers in China, and it was cited in US Supreme Court amicus briefs in TikTok Inc. v. Garland. This is not a theoretical risk — it is an active federal legal liability. Combined with ByteDance's COPPA lawsuit, the Protecting Americans from Foreign Adversary Controlled Applications Act, and India's prior Chinese app ban, Lark's addressable enterprise market in the US, EU, and allied nations is structurally and severely impaired. The product scores well; the geopolitical and legal overhang is company-defining.
