Top Tech Startups in Bengaluru, India in 2027

LH2 AI Labs is building the post-training infrastructure for frontier AI. We connect private, high-quality institutional datasets and vetted domain experts to the pipelines of frontier AI labs and enterprises, across coding, computer use, agentic workflows, medical, audio, and company operations. Frontier models have already learned from most of the public web. The next capability gains will come from data and environments grounded in real production work: tasks with meaningful state, reliable verification, realistic tools, and reward signals that can't be easily gamed. That's the problem we're built to solve. Most of our work sits in post-training: supervised fine-tuning data, preference data for RLHF, RL environment construction, and domain-specific evaluations that expose real failure modes. We also supply pre-training data where what's needed is genuine distributional novelty rather than scale. Our vision is to make high-quality post-training data as readily available to frontier models as compute is today. We're founded by second-time founders who have built and sold companies before, and we're based in Bengaluru. We're hiring engineers and researchers to build RL environments, model-breaking tasks, and evaluation systems. This is a chance to join early and shape how the next generation of AI models is trained.

Thor’s Hall is building a performance-based network for creators, publishers, marketers and online communities. We help partners monetize their audiences without having to build the technical infrastructure themselves. Thor’s Hall handles dedicated landing pages, campaign tracking, reporting and partner management while our partners focus on bringing quality traffic through the channels they already understand. Our model is simple: if a partnership generates revenue, everyone involved shares in the results. We currently focus on online gaming and iGaming, with the goal of building a wider network of creators, publishers and growth partners across multiple markets.
