Top Tech Startups in United States in 2026

Radiology is the second most used healthcare service, used by over 51% of the workforce annually. Despite the critical role of radiology in healthcare, the process for undergoing a medical imaging exam has remained unchanged for decades. OneImaging is solving this with a concierge approach and a premium-quality radiology network of over 4,000 vetted providers across 48 states, which also reduces imaging costs by 60-80%. Our solution helps patients and families access essential radiology services at fair prices and without surprise bills, all while delivering immediate savings and ROI for employers and payers on every exam.

The physical world runs on some of the most complex supply chains in existence. Distributors, manufacturers, and their partners manage thousands of SKUs, juggle siloed systems, and rely on tribal knowledge that never gets captured. The tools built to run these businesses—legacy ERPs, spreadsheets, disconnected portals—weren't designed for the speed, intelligence, or scale the industry now demands. We're changing that from the ground up. Matterhaul sits above the systems these businesses already run. We unify their data into a single intelligent layer, deploy AI agents across quoting, order entry, procurement, and dispatch, and surface the insights teams need to move faster and make better decisions, without ripping out what's already in place. That's the wedge. The vision is bigger. As we build the unified data layer and the agentic workflows on top of it, we're assembling the foundation for something the industry has never had: a purpose-built, AI-native platform for the physical world that doesn't just automate what ERPs do today, it does what they were never capable of. Capturing expert judgment. Compounding institutional knowledge. Turning every transaction into a signal that makes the next one smarter. We're a small team with deep roots in this space. Matterhaul's founders grew up in the trades and spent careers building systems and products for the physical world at companies like Stripe, Verkada, and Cisco Meraki. We're backed by leading investors, based in San Francisco's SOMA/Transbay neighborhood, and we believe in being close to our customers and to each other. We spend time on job sites, in distribution centers, and alongside the operators who run these businesses every day. We move fast, ship often, and build for the people who actually do the work.

Blue Rose Research is a project of OpenLabs to help progressive campaigns and issue orgs make higher quality strategic decisions with better polling and message testing. In the 2022 midterms, we advised major progressive organizations on directing hundreds of millions of dollars to the right ads and states, tested thousands of ads and talking points from state legislature to governor and senate races, and gave strategic election forecasting advice that was more accurate than public polls. Our team of 20+ passionate and progressive software engineers, machine learning engineers, and social scientists specialize in: Polling: Solving fundamental problems plaguing the polling industry today by applying state of the art tools from machine learning and Bayesian statistics. Message and creative testing: Providing rapid turnaround testing guidance for communications professionals on what messaging works and what doesn’t on the key issues of the day.

We are launching a Memecoin with the goal of archiving more than 100m USD market cap.

LexClaro is a multilingual AI legal-tech platform that turns complex contracts into clear, human language for individuals, freelancers and SMEs. Every year, millions of people sign rental agreements, employment contracts, shareholder agreements or service contracts they don’t fully understand. Legal language is slow, expensive to interpret and quietly shifts risk to the weaker side. LexClaro fixes that. Users upload a contract and, within minutes, LexClaro analyses it, summarises the key points and highlights obligations, rights, deadlines and risks — in their own language. No legal jargon, no guesswork, no waiting for appointments. We currently support 8+ languages and multiple contract types, designed for both personal and professional use, with a strong focus on real-world documents: housing, employment, startup equity, services and B2B deals. We’re now in Phase 4: moving from our MVP into a full SaaS web app, including live voice chat for contracts (ask questions in real time, get clear explanations plus a transcript and saved session). Next on the roadmap (Phases 5–6) is LexClaro Business: accounts for teams, role-based access, template libraries, versioning, contract comparison (original vs. edited, with changes and risk shifts clearly marked), bulk workflows and deeper integrations into HR, real estate and fintech ecosystems. The platform is currently in beta with early users testing across multiple countries. We are iterating fast on UX, language quality and legal clarity, using real contracts to improve our flows and strengthen trust. We don’t try to replace lawyers, but to become the first layer of clarity before anyone signs or negotiates — a practical legal “front door” for everyday life and business. LexClaro Global S.L. is headquartered in Spain and built from day one for international markets. On Wellfound, we’re looking to connect with growth, marketing and strategic co-founder profiles who believe in building a global brand around legal clarity.
