Tuya’s CoBuilder: Making AI Hardware Development as Easy as Talking
Q2 2026 revenue accelerates 16% as Tuya pivots from IoT platform to AI-native hardware enabler, with the launch of a vibe-coding tool that compresses the path from idea to device.

What Changed
Tuya reported Q2 2026 revenue of $92.9M, up 16% year-over-year, accelerating from 8.3% in Q1. The PaaS segment grew 16.9%, with strong demand across home appliances, smart door locks, and AI companion products. But the more consequential shift is strategic: the company launched Tuya CoBuilder, an AI development gateway that lets developers describe a product in natural language and receive working firmware, panel, and agent—closing the gap between concept and physical device.
Tuya CoBuilder applies coding to AI hardware development, enabling developers to cover the core development process from product concept to physical device validation using natural language, further shortening AI hardware development cycles.
This is a natural evolution of the company's long-standing push into AI, but it represents a step-change: instead of offering AI features as an add-on to its IoT platform, Tuya is now making the platform a default gateway for AI hardware creation. CFO Alex Yang framed it as a "default gateway" for developers, and in just over a month, the tool has expanded to 30 product categories, with average panel-generation time down to ~190 seconds.
The AI Companion Validation
The quarter also provided early market validation for AI-native devices. During China's June 18 Shopping Festival, a device called Fuzozo, built on Tuya's solutions, ranked #1 in the AI toy category on Tmall. “Shipment volumes of the devices powered by our solutions continue to expand... Beyond basic voice interactions, we have been building out capabilities in multimodal perception, persona and memory, content services and user engagement.” — Yi Yang, Co-Founder and CFO · 2026-08-24 This matters because it shows consumer acceptance of a whole new device category—one that didn't exist before the LLM era.
The company intends to monetize this across its three segments: PaaS (chip/module), smart products (finished devices), and AI applications (subscription services). Management noted that AI application growth decelerated to 3.9% in Q2, but that was due to a deliberate shift away from lower-margin B2B projects toward subscription-based B2C services, which grew 22%. “We are advancing our developer tools beyond development assistance towards end-to-end delivery capability, spanning product definition, software generation and deployment on physical devices.” — Yi Yang, Co-Founder and CFO · 2026-08-24
Margin Pressure and Strategic Pass-Through
Not everything is rosy. Blended gross margin fell to 46.3% on upstream semiconductor costs and business mix. Yet management emphasized that they absorbed the cost increases to protect customer relationships. “In Q2, what we're doing is that the major of the product we just passed through the cost raise... we maintain the gross profit and – but we don't stick to the gross margin.” — Yi Yang, Co-Founder and CFO · 2026-08-24 This echoes the prior quarter's approach: “we'll pass through those costs to the downstream side.” — Yi Yang, Co-Founder and CFO · 2026-05-12 The difference now is that the company sees a path to margin recovery through new AI capabilities and value-added services, rather than simply waiting for chip prices to fall.
A Deeper Developer Moat
The strategic bet is that CoBuilder will expand the developer base beyond traditional hardware engineers to product managers and even non-coders. In the Q&A, Alex Yang compared it to the arrival of vibe coding for software: “So CoBuilder will be kind of the – in the hardware world, should be kind of the momentum, like, wow, you have the vibe code maybe 1 year before. And we believe that will be default gateway.” — Yi Yang, Co-Founder and CFO · 2026-08-24 That aligns with the company's earlier emphasis on lowering the barrier for AI hardware development, as discussed in the May call: “we really upgraded our entire platform architectures into large language model hosted.” — Yi Yang, Co-Founder and CFO · 2026-05-12 Now it's making that LLM power directly consumable by non-developers.
Why It Matters
Tuya is no longer just a smart-home connectivity platform. It is positioning itself as the "shop floor" for physical AI—the place where AI-enabled devices are defined, built, and deployed. The launch of AI companion products and the AI hardware boom are early wins. By offering AI coding tools, the company hopes to compound its network effects: more developers → more device diversity → more data → better AI services → more developers.
The market hasn't fully re-rated the stock for this pivot yet (market cap ~$1.27B, with a large cash buffer of $976M), but the revenue acceleration and the tool's early traction suggest the strategy is gaining momentum. If CoBuilder can genuinely compress the hardware development cycle from months to days, it could unlock a wave of AI-native devices that only Tuya's platform is optimized to serve.
