Trustap
Trustap is an Irish fintech that provides escrow-style, milestone-based payment infrastructure for online marketplaces, ecommerce platforms and individuals. Acting as the merchant of record, it holds a buyer's funds until goods or services are confirmed as delivered, then releases them to the seller - reducing fraud, chargebacks and disputes for high-value and peer-to-peer transactions. Founded in Cork in 2017 by Conor Lyden after he was scammed buying football tickets, the company now works with 250+ partners across roughly 27 countries and is building Trustap Index, a product that makes marketplace listings machine-readable and transactable by AI shopping agents.
Stripe
Stripe is a financial infrastructure company that lets businesses accept payments and run their money operations through a set of developer-friendly APIs. Founded in 2010 by Irish brothers Patrick and John Collison, it powers everything from indie side projects to Fortune 500 checkouts, processing more than $1.9 trillion in payments in 2025. Beyond core card processing, Stripe offers billing, fraud protection, business incorporation, card issuing, tax automation, and banking-as-a-service, positioning itself as the economic layer of the internet.

Dill
Dill is a San Francisco fintech, founded in 2022 and backed by Y Combinator (W23), that helps construction wholesalers, distributors, and suppliers get paid faster. Its software digitizes the paper-heavy back office of the building-materials trade - online credit applications, accounts-receivable automation, white-labeled payment portals, and lien-rights tracking - and plugs into distribution ERPs like Epicor Prophet 21 and Eclipse. The pitch is simple: suppliers spend less time chasing invoices and more time selling.
NexHealth
NexHealth is a San Francisco-based health technology company building the patient experience platform for medical and dental practices. Its software gives doctors EHR-integrated online scheduling, patient messaging, digital paperwork, recalls, reviews and payments, while its Universal API and proprietary Synchronizer let developers read and write data across 20+ practice management systems in real time. Founded in 2017 by Alamin Uddin and Waleed Asif, NexHealth reached unicorn status in 2022 with a $125M Series C at a $1B valuation and serves more than 10,000 practices.
B12
B12 is a New York-based software company that builds an AI-powered, all-in-one platform for professional service providers - lawyers, accountants, consultants, and other small firms - to get online and run their businesses. Its AI generates a complete, industry-specific website in about 60 seconds, then pairs that automation with on-platform human designers, copywriters, and SEO specialists through a system the company calls Orchestra. Beyond websites, B12 bundles scheduling, intake forms, e-signatures, invoicing, payments, email marketing, and a client contact manager into one subscription.
