SuperAnnotate bets on owned AI training data: $36M Series B, 1,450% search surge
KTH-origin platform for building and fine-tuning AI training data; $36M Series B with NVIDIA and Databricks; 5x growth; #26 US trending topic Aug 2026
SuperAnnotate
What the business is
San Francisco-based AI data platform: teams create, manage, annotate, fine-tune, and evaluate training datasets for computer vision and LLMs, with a marketplace of pre-qualified annotation teams.
Starting capital：Early backing from KTH Holding (amount undisclosed); $36M Series B led by Socium Ventures (Nov 2024) brought total past $53M; ~$75M raised by 2026
How it started
While pursuing a PhD on image segmentation at KTH, Vahan Petrosyan built a tool to manage and automate image annotation. He and his brother Tigran Petrosyan, an ETH Zurich graduate, along with KTH student Oscar Örnberg, went through KTH Innovation Launch from 2017, graduated in October 2019, and were admitted to UC Berkeley's SkyDeck accelerator. They founded SuperAnnotate to sell the tool to developers and enterprises.
What happened
SuperAnnotate grew from image-labeling software into a data platform for fine-tuning, iterating, and evaluating AI datasets, adding RLHF workflows and a marketplace of pre-qualified annotation teams. Clients included Databricks and Canva. In November 2024 it raised a $36M Series B led by Socium Ventures with NVIDIA, Databricks Ventures, and Lionel Messi's Play Time Ventures, taking total funding past $53M; a later Series B-II brought it to about $75M. Kognic reported 5x software revenue growth in 2024 and a tripled customer base.
How it ended up
Scaling: ~$75M raised with NVIDIA, Databricks, and Dell Technologies backing; 5x software revenue growth in 2024; tripled customer base; and a 1,450% search-growth month that made it #26 on Exploding Topics' August 2026 top-100 US trends list.
Background
SuperAnnotate is an AI data platform founded by brothers Vahan and Tigran Petrosyan, with KTH student Oscar Örnberg, out of Vahan's PhD research on image segmentation at KTH. After KTH Innovation Launch and UC Berkeley's SkyDeck accelerator, the company built software that started as an image-annotation tool and became a platform for creating, managing, fine-tuning, and evaluating training datasets.
The founding bet was that as AI models multiplied, high-quality, domain-specific data — not model size — would be the differentiator, and enterprises would pay for an easy-to-use platform rather than generic outsourced labeling. Vahan described it as 'a Swiss Army Knife for modern AI training data.'
The bet compounded when generative AI took off: SuperAnnotate added RLHF workflows, model comparison, and fine-tuning tools, and counted Databricks and Canva among roughly 100 customers. In November 2024 it raised a $36M Series B led by Socium Ventures with NVIDIA, Databricks Ventures, and Play Time Ventures, bringing total funding past $53M; a later Series B-II brought it to about $75M.
By 2026 the company reported 5x software revenue growth in 2024 and a tripled customer base, and its name became a search phenomenon: Exploding Topics ranked SuperAnnotate #26 on its August 2026 list of the top 100 trending topics in the US, with 1,450% search growth.
What has to be true
- Dataset quality, not size, became the recognized lever on AI model performance, so the category grew with the market.
- Starting from a painful manual bottleneck — image annotation — gave SuperAnnotate real customers before the AI boom made data infrastructure fashionable.
- The platform kept the same buyer as AI shifted from computer vision to LLMs, letting the wedge carry the company into RLHF and fine-tuning.
- NVIDIA, Databricks, and Dell backing validated the infrastructure thesis and brought ecosystem distribution.
- A 1,450% search-growth month in 2026 shows the company's name itself became a topic people look up as AI data quality goes mainstream.
What can be applied
Ride the wedge that changes: the image-annotation tool became an AI data platform by keeping the same customer — teams building training data — as the data moved from images to LLMs.
Aftermath
As of August 2026 SuperAnnotate was scaling as an AI data platform with roughly $75M raised (NVIDIA, Databricks Ventures, Dell Technologies Capital among investors), 5x software revenue growth in 2024, a tripled customer base, and RLHF and fine-tuning tooling at the center of its product. Its 1,450% search-growth month put it #26 on Exploding Topics' August 2026 top-100 US trends list, and it continued to develop agent-model support and pipeline automation per its product changelog.
