3LC (www.3lc.ai), the data-centric AI platform company transforming how enterprises build and deploy computer vision models, today announced a $2 million investment from Swedish early-stage technology investor Spintop Ventures.
Spintop Ventures is a leading Nordic VC firm investing in software-driven technology companies in seed stage. Since 2010, Spintop has backed companies that have later been acquired by global leaders such as Klarna, Bentley Systems, Cisco and Aveva.
The investment reflects strong commercial momentum and growing enterprise adoption of 3LC’s full-loop platform for Physical AI, combining labeling, debugging, and data quality optimization to improve model accuracy while reducing training and inference costs.
“Spintop brings a rare combination of deep understanding of AI and computer vision, strong enterprise software experience, and a highly relevant industrial network,” said Paul Endresen, CEO and Founder of 3LC. “This investment validates both our technology and our growing traction with global enterprise customers.”
The new capital will support 3LC’s continued growth toward a planned Series A within the next 18 months. Funds will be used to scale sales and marketing efforts while strengthening the technical team to meet increasing enterprise demand.
As part of the investment, Spintop Partner Finn Persson will join the 3LC Board of Directors.
“3LC addresses one of the most critical bottlenecks in applied AI: data quality,” said Finn Persson, Partner at Spintop Ventures. “The company has demonstrated strong product maturity, clear enterprise value, and impressive customer validation. We see significant potential for 3LC to become a category-defining platform in data-centric AI.”
The investment comes as 3LC continues to deepen engagement with large enterprise customers and expand its footprint across industries such as aerospace, energy, agriculture, robotics, and autonomous systems. Since its founding in 2023, 3LC has now raised $7.0 million in total funding.
In parallel, 3LC has strengthened its strategic capacity through the formation of an Advisory Board comprising:
- Stacey Svetlichnaya, Founding ML Engineer at Weights & Biases
- Erik Åsberg, CTO of eSmart Systems
- Ken Jacobsen, serial entrepreneur in the U.S. software industry
About 3LC
Three Lines of Code (3LC) is a US- and Norway-based AI scale-up founded in 2023 by a seasoned team of computer scientists and AI specialists.
3LC delivers the first full-loop platform for AI data preparation and optimization, combining labeling, debugging, and diagnosis in one integrated workflow. The platform connects directly to customers’ existing data, models, and training pipelines — requiring no data movement and running fully within the customer’s own infrastructure, ensuring complete data security.
By focusing on data quality rather than model architecture alone, 3LC enables enterprises to build more accurate models with significantly less data, resulting in smaller models, faster training cycles, and substantial reductions in data science effort.
3LC’s rapidly growing customer base includes global enterprises across aerospace, energy, and industrial automation, alongside leading AI-driven companies such as Syngenta, Equinor, Saga Robotics, eSmart Systems, Wenn, Helin and Biodrone.
