LineWise bets 24/7 AI 'virtual engineer' can cut factory downtime; YC X25, $1.1M pre-seed
Thai-founded LineWise joined YC X25 and raised $1.1M for an AI 'virtual engineer' that cuts factory downtime and defects.
LineWise
What the business is
An industrial AI company selling a 24/7 'virtual engineer' that monitors production lines, finds root causes of defects and stoppages, and walks factory teams through fixes.
Starting capital：$1.1 million pre-seed from A2D Ventures, Y Combinator, Exitfund, REMUS Capital, SBXi Fund and Team Ignite Ventures.
How it started
LineWise was founded in 2025 in Thailand's manufacturing heartland by James Kujareevanich (MIT MBA, ex-McKinsey, with factory-efficiency work at Rolls-Royce), CTO Zhichu Ren (robotics for materials research), CPO Wenbo Zhang (ex-founding engineer at Greyscale AI) and COO Napon Tang-Aromsuk (ex-Rolls-Royce lean manufacturing). Their thesis: unplanned downtime can cost manufacturers over $100,000 per hour, and defect rework adds hidden losses on high-speed lines.
What happened
The startup joined Y Combinator's X25 batch and in September 2025 raised a $1.1 million pre-seed from A2D Ventures, Y Combinator, Exitfund, REMUS Capital, SBXi Fund and Team Ignite Ventures. Its multi-agent AI ingests sensor data, event logs, OEM manuals and past fixes to deliver root-cause analysis and step-by-step troubleshooting. By the raise it had already secured five paid pilots with large manufacturers, including NASDAQ-listed leaders in packaging, food & beverage and consumer electronics, and planned to expand across North America and Asia.
No ending yet — it is still running.
Background
LineWise was founded in 2025 in Thailand's manufacturing hub by James Kujareevanich (MIT MBA, ex-McKinsey, with factory-efficiency work at Rolls-Royce), CTO Zhichu Ren, CPO Wenbo Zhang and COO Napon Tang-Aromsuk. The founding insight: manufacturing's two most expensive problems — unplanned downtime, which can exceed $100,000 per hour, and defect-driven yield loss on high-speed lines — are exactly where scarce senior engineers spend their time firefighting.
LineWise's answer is a multi-agent AI 'virtual engineer' that ingests sensor data, event logs, OEM manuals and past fixes to give rapid root-cause analysis and step-by-step troubleshooting, working 24/7. The company joined Y Combinator's X25 cohort and raised $1.1 million in pre-seed funding in September 2025 from A2D Ventures, Y Combinator, Exitfund, REMUS Capital, SBXi Fund and Team Ignite Ventures.
The wedge is deliberately narrow: can-making and packaging lines, where wrinkles, leakers, false seams and misfeeds waste material and force rework. By the time of the raise, LineWise said it had secured five paid pilots with large manufacturers, including NASDAQ-listed leaders in packaging, food & beverage and consumer electronics, and was expanding across North America and Asia.
What has to be true
- Downtime can cost manufacturers over $100,000 per hour and defects add hidden rework losses — a huge, measurable problem that AI is well-suited to attack.
- Senior process and maintenance engineers are scarce and slow to review records; an AI trained on manuals, logs and past fixes answers in minutes, 24/7.
- Starting with can-making and packaging lines gives a narrow wedge where defects are visible and ROI immediate, before expanding to other industries.
- YC X25 plus deep-tech backers like A2D Ventures let a Thai-founded team sell into North America and Asia from day one.
What can be applied
Industrial AI is sold on narrow, measurable pain: start with one line type where defects and downtime are visible and ROI immediate, then expand — the pilot is the pitch.
Aftermath
As of late August 2026, LineWise is live with paid pilots: it raised a $1.1 million pre-seed in September 2025 after joining YC's X25 batch, and is expanding its AI engineering team and defect-prevention coverage across North America and Asia, starting with can-making and packaging lines. It aims to become the industrial AI backbone for manufacturers navigating Industry 4.0. Revenue and follow-on rounds are undisclosed; the open test is whether paid pilots convert into recurring contracts beyond packaging.
