Equity Forge is transforming how people build skills and wealth — creating pathways from verified volunteering → paid marketplace work → startup equity participation, all on one platform. Hiring still relies on resumes, interviews, and credentials that are self-reported and easily gamed. AI is making this worse — increasing application volume while reducing signal trust. No one has built trusted infrastructure for portable professional identity, because no single employer benefits enough to create it. We're building it. Our foundation is DemocracyLab, a 501(c)(3) that has facilitated over 10,000 skilled volunteer placements since 2018. Equity Forge expands these proven pathways into paid and equity opportunities — helping professionals earn compensation proportional to the value they create. Our core innovation is authentic professional identity built through activity tracking, documented artifacts, peer attestation, and manager verification. When credentials are trustworthy, they become worth investing in — and that investment compounds over time. We practice what we build — our team earns ownership through the same dynamic equity model we're creating for others.

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.

Tune is the next-generation dating app, approved on the App Store & patent pending. Seattle launch in mid-January. Dating isn't symmetric, so Tune is built for both sides: two modes, and each member chooses theirs. Tune's AI learns from how you talk with your matches and finds people who fit you, so your dates get better the longer you use it. And Tune is built to spread: Tune Wink, the Circle of friends, Tune events and Tune Perks. We're a small, AI-first team. We try new things fast, we're not afraid to be wrong, and we learn from each mistake as fast as we can. We're building Tune city by city, beginning in Seattle.
