RightData’s $6 Million Bet: Make Bad Data Boring Before AI Makes It Expensive
Enterprise AI has made an old plumbing problem newly urgent: a pipeline can run perfectly while delivering the wrong answer. RightData sells a three-part control system designed to catch that failure before it reaches a dashboard, an audit, or an algorithm.
CompStak
CompStak is a New York-based commercial real estate data and analytics company that runs a crowdsourced marketplace where brokers, appraisers and researchers trade verified lease and sale comps for credits. Founded in 2012 by former broker Michael Mandel and engineer Vadim Belobrovka, it turns hard-to-find transaction details - starting rents, net effective rents, cap rates, net operating income - into structured, analyst-reviewed data used by many of the largest CRE investors, lenders and banks in the U.S.
Narrative I/O
Narrative I/O is a New York-based data infrastructure company that makes incompatible data work together. Its platform automatically normalizes disparate datasets, resolves identity, and lets companies securely buy, sell, enrich, and activate data - increasingly delivered natively inside a customer's own Snowflake environment so no data has to move.

Protege
Protege is a New York-based AI data platform that connects owners of private, real-world data - hospitals, media libraries, motion-capture studios and more - with the AI labs and enterprises that need it to train, fine-tune and evaluate models. It licenses and curates proprietary datasets under strict privacy, IP and compliance controls, so data holders get paid and provenance is preserved. Founded in 2024 by Bobby Samuels and Travis May, Protege has assembled access to billions of clinical notes, hundreds of millions of medical images, and hundreds of thousands of hours of video and audio, positioning itself as core infrastructure for the post-web era of AI development.
Taktile
Taktile is an AI decision platform for banks, insurers and fintechs. Its Agentic Decision Platform lets risk and engineering teams combine AI agents, business rules, third-party data and human oversight to automate high-stakes decisions - approving customers, underwriting credit, flagging fraud and processing claims - using low-code building blocks, 200+ data integrations, and built-in testing and monitoring. Founded in 2020 by Maik Taro Wehmeyer and Maximilian Eber, the company operates across New York, Berlin, London, Sao Paulo and Iasi, and raised a $110M Series C led by Goldman Sachs Alternatives in June 2026.
Nomad Data
Nomad Data is a New York-based AI platform that helps companies find, buy, and understand external data. Founded in 2020 by Brad Schneider and Justin Manikas, it began as a marketplace matching data buyers to a network of thousands of providers - buyers submit a use case, and providers respond with data that can actually solve it. The platform has since expanded into an AI layer for reading unstructured documents (its Doc Chat product) and managing data relationships, serving hedge funds, private equity, insurance, and asset-management firms that spend heavily on third-party data.
Centific
Centific is a Redmond, Washington-based AI and data company that calls itself the hidden infrastructure behind world-class AI models. Its AI Data Foundry combines a global network of 1.8 million-plus domain experts with platforms for data collection, annotation, RLHF, model evaluation, governance and multimodal orchestration, helping enterprises and frontier model labs move AI from experimentation to production. Founded in 2020 out of the former Pactera EDGE business, Centific is a recognized NVIDIA innovation partner and raised a $60M Series A led by Granite Asia in June 2025.
