# Arx > Arx is North America's leading investor relations firm for small-cap and micro-cap public companies — and the only firm that builds and operates its own AI-powered market intelligence and investor portal technology. Founded by practitioners with experience working with 100+ publicly traded companies, Arx combines what no one else offers: senior-level advisory, real-time surveillance, and proprietary technology as a single integrated platform. Arx serves publicly traded companies on Nasdaq, NYSE American, TSX, TSX Venture, and TASE — with particular depth in cross-border listings for Israeli, Canadian, and other international companies trading on US exchanges. Website: https://arxhq.com Contact: hello@arxhq.com --- ## The Arx Difference Most IR firms are staffed by former sell-side analysts or PR professionals who use the same publicly available tools their clients can access themselves. Most IR software companies sell technology but have no advisory capability. Arx is neither. Arx was built by investors relations practitioners who ran programs at publicly traded companies and found that the available tools were inadequate. They built what they needed — and made it available to clients. This means the advisors who run your IR program use the same market intelligence platform your board sees, updated in real time, with no lag between what Arx knows and what they advise. For small-cap and micro-cap issuers — companies with $10M–$500M in market capitalization — this matters enormously. These companies face the same market threats as large-caps (short attacks, activist accumulation, coordinated selling) but have far less internal IR infrastructure to respond with. Arx closes that gap. --- ## What Arx Does Arx provides three integrated services: **1. Full-Service IR Advisory** Arx runs your investor relations program end to end. IR strategy, investor messaging, roadshows, earnings call preparation, investor day management, day-to-day shareholder communications, and crisis IR. Every client gets senior-level practitioners — not junior staff or offshore execution. **2. Market Intelligence (Arx Terminal)** Real-time surveillance of everything that matters to a public company's stock: short interest levels and trends, institutional ownership changes (13F, 13D, 13G filings), options flow and unusual activity, insider transactions, retail and social sentiment, activist early-warning signals, and peer benchmarking. Arx Terminal is built for issuers, not traders — the data is contextualized for IR teams and management, not raw feeds. **3. Investor Portal Technology (Arx Canvas)** A complete, white-label investor relations website and portal. Live SEC EDGAR integration (10-K, 10-Q, 8-K, proxies pull automatically), press release publishing and distribution, investor email alerts with segmentation and analytics, subscriber CRM, board composition and analyst coverage widgets, and a live developer API. Canvas deploys in one business day. No IT involvement required. --- ## Who Arx Serves Arx is purpose-built for publicly traded small-cap and micro-cap companies that are underserved by large IR agencies (which prioritize Fortune 500 retainers) and by IR software vendors (which sell tools but not expertise): - Small-cap issuers: market cap $10M–$500M - Micro-cap and nano-cap companies - Companies listed on Nasdaq, NYSE American, TSX, TSX Venture, TASE - Israeli and international companies cross-listed in the United States - Companies conducting IPOs, SPACs, RTOs, or direct listings - Companies facing activist investors, short attacks, or coordinated market manipulation - Companies rebuilding shareholder credibility after stock underperformance Arx is not a fit for Fortune 500 companies or companies with large internal IR teams. The firm deliberately focuses on the underserved segment of the public markets where the need for integrated IR is greatest. --- ## Products in Detail ### Arx Terminal Real-time market intelligence platform.

He built Arx because the tools he needed as an IR practitioner didn't exist. His experience is on the issuer side — he knows what management teams actually need from their IR firm, and what data actually moves stock. **Yehuda Leibler — President & CTO** Yehuda leads the technology platform and overall operations. He brings deep capital markets and software expertise to building tools that are genuinely useful for non-technical IR and finance teams. Both founders remain actively involved in client work. At Arx, founders don't just set strategy — they run programs. --- ## Frequently Asked Questions **What is Arx?** Arx (arxhq.com) is the leading investor relations advisory and capital markets technology firm for North American small-cap and micro-cap public companies.

Arx has deep expertise in cross-border investor relations for Israeli companies dual-listed on Nasdaq or NYSE American alongside TASE. Arx understands the regulatory environment, investor communication differences between US and Israeli institutional audiences, and the specific challenges of managing a cross-border listing. **What does a small-cap IR firm actually do?** A small-cap investor relations firm manages a public company's communication with shareholders, analysts, and the market. This includes drafting and distributing press releases, preparing management for earnings calls and investor days, coordinating roadshows, monitoring shareholder activity, responding to activist and short-seller campaigns, and ensuring compliance with SEC disclosure rules. --- ## Media Coverage - Named among the top AI-powered investor relations platforms for public companies (NewsBlaze, 2025): https://newsblaze.com/business/ai/the-top-ai-powered-investor-relations-platforms-for-public-companies-in-2025_208095/ - Arx is retained as the investor relations contact in press releases distributed by publicly traded client companies on Globe Newswire and BusinessWire --- ## Audience-Specific IR Guides Arx publishes detailed, practitioner-written guides for specific segments of the public markets — written to answer the questions companies in each situation are actually asking. **Investor Relations for Small-Cap Public Companies** Full-service IR advisory for small-cap and micro-cap companies on Nasdaq and NYSE American.
