The platform searches across all company apps and data. It looks through documents, emails, code, and support tickets. Workers get answers to questions without searching multiple places.
Glean’s AI does more than search. It summarizes content, builds knowledge maps, and gives personal recommendations. The system learns what each worker needs based on their role.
Companies report that workers find information faster and make better decisions. Glean solves a big problem – helping workers find what they need in large organizations.
3. Snorkel AI
Snorkel AI fixes data labeling for machine learning. The company raised $100 million in May 2025. This values the company at $1.3 billion.
Creating labeled training data takes time and costs money. Manual labeling is slow and often wrong. Snorkel AI uses programmatic labeling to create labels automatically.
The platform lets data scientists write labeling functions instead of labeling by hand. These functions use business rules and existing models to generate labels. This cuts labeling costs by 90% and improves quality.
Companies in healthcare, finance, and manufacturing use Snorkel AI. The platform helps them build AI systems faster while meeting industry rules.
4. TensorWave
TensorWave provides AI computing infrastructure. The Las Vegas company raised $100 million in May 2025. AMD Ventures led the funding round.
The company builds AI cloud services using AMD GPUs. This gives customers an alternative to NVIDIA-based systems. TensorWave focuses on better price and performance for AI training and inference.
The platform includes optimized software, advanced cooling, and efficient power systems. Customers can cut AI computing costs by 40% compared to other cloud providers.
TensorWave addresses growing demand for AI computing power. The company gives organizations more choices and better prices in a market dominated by one vendor.
5. LMArena
LMArena runs the main platform for testing AI models. The company raised $100 million in May 2025. This values LMArena at $600 million.
The platform lets AI models compete against each other. Users submit questions and rate the answers. This creates rankings that show real-world performance, not just test scores.
LMArena tests models across many areas: coding, math, creative writing, and factual accuracy. The transparent rankings help developers and companies pick the right AI models.
Model creators optimize their systems to perform well on LMArena tests. This makes the platform a key driver of AI progress, similar to how app stores influence mobile development.
6. Lila Sciences
Lila Sciences builds AI for scientific discovery. The Cambridge company raised $200 million in March 2025. The platform speeds up research across multiple science fields.
The system combines AI reasoning with scientific databases. It reads millions of research papers and suggests new experiments. The platform can predict outcomes and spot potential failures before testing.
Lila Sciences goes beyond literature review. It proposes new experiments and research methods. This cuts discovery time and reduces costs for physical experiments.
The company works in drug discovery, materials development, and chemical synthesis. Flagship Pioneering and other science investors back the company.
7. Reflection.AI
Reflection.AI builds autonomous business systems. The Brooklyn company raised $130 million in March 2025. This values the one-year-old company at $580 million.
The platform creates AI systems that handle complex business decisions without human oversight. Unlike AI assistants that need supervision, these systems manage complete processes from start to finish.
The autonomous agents handle supply chain optimization, financial planning, and strategic analysis. They make decisions that align with business goals while adapting to changes.
Early users report better efficiency and decision quality. The technology helps organizations operate at machine speed while maintaining human-level judgment.
8. Celestial AI
Celestial AI uses light-based computing for AI workloads. The company raised $250 million in March 2025. This values Celestial AI at $2.5 billion.
The company’s photonic fabric technology uses light instead of electricity for computing. This reduces power consumption and increases speed for AI tasks. Light-based systems process information faster while generating less heat.
Traditional AI computing uses enormous amounts of power. Celestial AI’s approach cuts energy use by 10x while increasing processing speed. This makes large AI systems more sustainable and cheaper to run.
Major cloud providers test the technology for their biggest workloads. The photonic approach addresses the energy crisis in AI computing.
9. NeuralFlow
NeuralFlow creates AI-powered robotics systems. The Seattle company raised $175 million in February 2025. This values NeuralFlow at $1.8 billion.
The platform enables robots to learn complex tasks through observation and practice. Unlike traditional programming, robots watch humans perform tasks and adapt their behavior automatically. The system handles both physical manipulation and decision-making.
NeuralFlow’s robots work in warehouses, manufacturing, and food service. They can pick and pack items, assemble products, and prepare meals. The robots improve their performance through continuous learning from real-world experience.
Manufacturing companies report 60% faster deployment times compared to traditional robotic systems. The technology bridges the gap between flexible human workers and efficient automated systems.
10. Hippocratic AI
Hippocratic AI builds AI for healthcare applications. The company raised $141 million in January 2025. This values Hippocratic AI at over $1.6 billion.
