What SixSense does
SixSense is an AI-powered defect analytics platform purpose-built for semiconductor manufacturing. Founded in 2018 and headquartered in Singapore, the company serves wafer fabs, outsourced semiconductor assembly and test (OSAT) providers, and specialty foundries with a product suite organized around AI-ADC (Automated Defect Classification). The platform is built on proprietary vision foundation models pre-trained on millions of wafer-defect images using Vision Transformers, self-supervised learning, and diffusion models, with modules spanning Build AI (training), ClassifAI (production inference), VerifAI (drift detection and self-improvement), Dispose AI (lot disposition), CausifAI (root cause analysis), Predict AI (predictive inspection), Fast Die Registration (sub-pixel alignment), and a Knowledge Datalake for compounding manufacturing intelligence. Technical claims include >99% classification accuracy with zero defect escapes at line speed, sub-20ms inference on embedded hardware, and the ability to deploy production models in 2-3 days.
SixSense generates revenue through enterprise SaaS subscriptions and AI software licensing sold via direct field sales to global semiconductor manufacturers and through OEM partnerships where its AI is embedded inside inspection equipment. Pricing is quote-based with no public disclosure. Named customers include GlobalFoundries (200mm and 300mm fabs since 2022, AI Innovation Award 2025), JCET/STATS ChipPAC, Tong Hsing Electronic, Raytek, and Wavetek Microelectronics, with the platform processing over 100 million chips annually across deployed sites in Singapore, Taiwan, Malaysia, China, Israel, and the US.
The company has raised approximately $12.2 million across seed and two Series A rounds (Tin Men Capital 2022, Peak XV's Surge 2025), operates with ~35 employees across Singapore, San Francisco, Bengaluru, and Hsinchu County, and holds ISO 27001 certification. Co-founders Akanksha Jagwani (CEO, IIT/GE/Hyundai/A*STAR background) and Avni Agarwal (CTO, Forbes 30 Under 30 Asia 2025) lead the business. The strategic focus is on scaling AI-driven line-level factory intelligence across advanced packaging, compound semiconductors, and traditional fabs.

SixSense product offering
Product offeringCore offering
SixSense provides an AI platform for semiconductor fabs and OSATs that automates visual defect inspection, lot disposition, and root cause analysis across wafer fabrication and backend assembly operations. The platform is built around AI-ADC (Automated Defect Classification), which uses proprietary vision foundation models pretrained on millions of wafer-defect images to classify defects with over 99% accuracy and zero escapes at line speed. Supporting modules include Build AI for training data preparation, ClassifAI for production inference, VerifAI for model monitoring, Lot Disposition/Dispose AI for automated pass/hold/rework/scrap decisions, CausifAI for root cause analysis, and Predict AI for predictive inspection.
Product overview
SixSense is an AI platform for semiconductor fabs and OSATs (outsourced assembly and test companies) that automates defect inspection, lot disposition, and root cause analysis across wafer fabrication and backend assembly operations. The platform is organized around AI-ADC (Automated Defect Classification) as the core engine, which comprises Build AI (data preparation and model training), ClassifAI (production inference), and VerifAI (production monitoring with drift detection). Supporting modules include Lot Disposition / Dispose AI (automated pass/hold/rework/scrap decisions), CausifAI (root cause analysis through process tool correlation), Predict AI (predictive inspection and self-optimizing fabs), Fast Die Registration (sub-pixel die alignment for accurate inspection), and a Knowledge Datalake for compounding manufacturing intelligence over time. The platform uses a pretrained semiconductor vision foundation model and delivers over 99% classification accuracy with zero escapes at line speed, operated by the customer's own defect and yield engineers without AI specialist dependency.

Products and services
- AI-ADC (Automated Defect Classification) End-to-end AI solution for automating visual inspection in semiconductor fabs and OSATs, with tools for training (Build AI), production inference (ClassifAI), and model maintenance (VerifAI). Achieves over 99% classification accuracy with zero escapes at line speed, and integrates across different OEM inspection tool types and generations.
- Lot Disposition and Root-Cause Analysis Built on AI-ADC's trusted labels, automatically decides pass, hold, rework, or scrap for each lot, balancing yield impact, recurrence patterns, and defect severity. Correlates classified defects with tool, recipe, and chamber data across hundreds of steps, flagging drifting parameters and surfacing the quickest fix in minutes instead of weeks. Includes Dispose AI and CausifAI sub-modules.
- Predict AI Predictive analytics module that forecasts when, where, and what to inspect by learning defect likelihood across time, layers, and lots. Triggers proactive adjustments to inspection sampling and tools before faults occur, shifting fabs from reactive firefighting to self-optimizing production.
- Hierarchical AI for Real-Time Embedded Inspection Edge AI solution integrated directly inside AOI OEM machines for real-time inspection. Uses foundation model distillation and dynamic routing to achieve sub-20 millisecond decision times per image, 98.2%+ classification accuracy, and zero escapes on embedded hardware. Doubled inspection throughput and eliminated defect escapes in validation for an analog and embedded semiconductor leader.
- Fast Die Registration Sub-pixel die-to-die alignment technology that aligns reference and test die images in approximately 5ms (about 60x faster than conventional approaches). Reduces false alarms by approximately 50x and missed defects by approximately 500x, enabling accurate AI-based inspection at production speed without throughput overhead.
- Closed-Loop AI for Wafer Sort and Probe Mark Correction
