Undermind

AI Tools

At Undermind, we're building a search engine that can handle extremely complex questions. It’s geared at experts, like research scientists and doctors, who need to find very specific resources to solve high-stakes problems. We’ve rebuilt search from the ground up to address this. Our new approach employs high-quality LLMs to adaptively explore a database, mimicking how a human researcher carefully discovers information. This approach dramatically outperforms (by 10-50x) traditional keyword search and other modern AI-based retrieval methods. Our first target users are the 50 million researchers searching for scientific literature on PubMed and Google Scholar every month. We’ve have paying users across fields like medicine, ML, biotech, finance, and more.

Redouble AI

AI Tools

Redouble AI is the solution to scale human-in-the-loop for AI workflows in regulated industries. Instead of having to rely on slow and expensive human reviewers, Redouble’s clients save 80% of staff costs and significantly improve the accuracy and quality of their outputs by integrating our tool into their workflows. Addressing an $11BN market, the company is already generating revenue with its first set of clients. The founders are two serial entrepreneurs (who have built successful companies in AI and health-tech respectively) and a data engineering veteran who has written more than 120 enterprise-grade software applications.

Enterprises are paralyzed by the risks of deploying generative AI. Traditional methods like RAG and fine-tuning are brittle, expensive, and fail to prevent costly hallucinations or guarantee compliance in high-stakes environments. This lack of trust stalls innovation and blocks ROI. CTGT ensures strict, auditable adherence to your policies on the fly. We deliver defensible audit trails and remediate noncompliant model behavior, so outputs become more aligned with company policies over time, combating data and model drift. CTGT is backed by Google's AI fund (Gradient), General Catalyst, and luminaries like Paul Graham. We provide the control and confidence necessary to unlock the full potential of enterprise AI.

Glimmer is a new way to search massive PDFs using AI. If you've ever dealt with massive PDFs (i.e. over 1,000 pages), you know how broken search can be. You have no choice but to use “Cmd-F” and manually sift through thousands of search results to find specific information. Professionals in construction, law, finance, and healthcare spend hours doing this every day. Glimmer makes searching these large documents 10x easier. When you upload a PDF, Glimmer uses AI to intelligently index your documents. You can then search your PDF in natural language and get answers with verifiable page sources. You can get started with Glimmer for free with any kind of PDF at withglimmer.com.

Capitol AI

AI Tools

Capitol builds intelligence infrastructure for companies overwhelmed by data but starved for clarity. Today, 80% of enterprise AI projects fail because outputs aren't accurate, attributable, or usable. Capitol AI works with companies in high-stakes industries to turn information into intelligence that drives decisions with model-agnostic, purpose-built infrastructure. Capitol is building a different future - one where institutions, creators, and analysts stay in control of their knowledge, their IP, and their value. We deliver a model-agnostic platform that turns complexity into decision-grade insight. We don't believe the future should be dictated by a handful of closed models. We enforce attribution, minimize hallucinations, and preserve temporal accuracy - giving companies trusted answers they can act on.
