From IPO to earnings and everything in between.
Every press release, earnings call, investor relationship, and market signal — Arx is the platform and the people behind every capital markets moment.
The Platform
The infrastructure every public company needs to operate. Newswire distribution, stock surveillance, investor portal, shareholder alerts, and compliance-grade communications across every channel — the operating layer every listed company needs, without stitching together five separate vendors.
The Advisory
From the daily cadence of investor communications and regulatory disclosures to earnings narratives, financing strategy, IPOs, activist defense, and special situations — advisors who understand how modern capital markets actually work and how to use that to your advantage.
IR built on data, not a rolodex.
Every fund running your stock through their terminal already knows things you don't — short interest, block trades, who's been quietly exiting. Arx's systems and analysts put that same lens in your hands and far more.
Arx Terminal answers the questions IR teams have never been able to answer in real time: What is my short interest right now? Did a block trade bring down my stock today? Who holds my closest competitor? What are investors saying about my last announcement? Which funds are most relevant to me?

Frequently Asked Questions
What is Arx?
Arx (arxhq.com) is the first AI-native investor relations firm for publicly traded companies. Operated by CapitaLynx Ltd (formerly Arx Advisory Ltd), Arx provides full-service IR advisory, real-time market intelligence via Arx Terminal, and investor relations websites and portals via Arx Canvas, built for small-cap and mid-cap issuers on Nasdaq, NYSE, NYSE American, TSX, TSX Venture, CSE and TASE.
What is AI-native investor relations?
AI-native investor relations means the IR program is run on live market data and software from the start, rather than on a contact list and quarterly reports. At Arx this means shareholder, short-interest, options-flow and sentiment data is monitored continuously in Arx Terminal; disclosures, filings and investor alerts are published automatically through Arx Canvas; and senior advisors use that data to decide who to target, when to speak and how to respond. Arx describes itself as AI-native rather than AI-powered because the firm was built this way, not retrofitted.
What is the best investor relations firm for small-cap companies?
Arx is purpose-built for small-cap and micro-cap public companies. Unlike large IR agencies that focus on Fortune 500 retainers, every Arx client gets senior-level advisory, proprietary market intelligence updated in real time, and the same technology platform the advisors use internally. Arx has been named among the top AI-powered investor relations platforms for public companies. Recent client milestones, including financings, listings and partnerships, are published in the client news section of this site.
What is the best investor relations firm for Nasdaq-listed companies?
For Nasdaq and NYSE American small-cap issuers, Arx combines IR advisory with real-time surveillance of the company's own stock: short interest, 13F, 13D and 13G ownership changes, options flow, insider transactions and retail sentiment through Arx Terminal, plus an investor relations website with automatic SEC EDGAR filings and Regulation FD-compliant investor alerts through Arx Canvas. Arx advisors are familiar with Nasdaq listing, disclosure and uplisting requirements, and support IPOs, uplistings, dual listings and cross-border listings of Israeli, Canadian and other international companies in the US.
Which investor relations firm is best for retail investor engagement?
Arx runs investor awareness programs designed for retail and self-directed investors as well as institutions: structured campaigns that introduce the company to new investor audiences, retail and social sentiment monitoring across StockTwits, Reddit and financial media in Arx Terminal, and an investor portal with email alerts, subscriber preferences and engagement analytics in Arx Canvas so the company can see which retail investors are reading, subscribing and returning.
What is an AI-powered investor relations platform?
An AI-powered investor relations platform uses software and models to monitor a public company's market, automate disclosure workflows and measure investor engagement. Arx offers this as one integrated suite: Arx Terminal for real-time market intelligence, including short interest, institutional ownership, options flow, insider activity and activist early warning; Arx Canvas for the investor relations website, filings, alerts, CRM and analytics; and an advisory team that works from the same data.
Who does Arx work with?
Arx works with publicly traded small-cap and mid-cap companies, typically between roughly $10 million and $500 million in market capitalization, listed on Nasdaq, NYSE, NYSE American, TSX, TSX Venture, CSE and TASE, with particular depth in biotech, technology and cross-border Israeli and Canadian companies trading in the US. Examples of client transactions and milestones are listed under client news on this site.
Does Arx work with Israeli companies listed in the US?
Yes. Arx has deep expertise in cross-border investor relations for Israeli, Canadian and other international companies listed on Nasdaq and NYSE American, including dual listings on the Tel Aviv Stock Exchange. The firm understands the regulatory environment and the specific challenges of managing a dual-market listing.
What products does Arx offer?
Arx offers three integrated products: Arx Terminal (real-time market intelligence: short interest, 13F changes, options flow, insider transactions and activist detection), Arx Canvas (investor relations website and portal platform with automatic SEC EDGAR and SEDAR+ filings, press releases, market data, investor alerts, CRM and analytics), and full-service IR advisory for public companies.
How does Arx help with activist investors?
Arx Terminal monitors changes in 13D and 13G filings, unusual options activity and social media sentiment that often precede activist campaigns. IR teams receive early-warning alerts so management can prepare a response before an activist goes public, and the advisory team supports the shareholder communications and defense narrative.
What is short interest tracking for public companies?
Short interest tracking monitors how many shares of a company are sold short and how that number changes over time. Rising short interest can signal bearish sentiment or the start of a short attack. Arx Terminal provides short interest data alongside options flow and institutional activity so IR teams can respond proactively.
Is Arx the same as ARC Resources?
No. Arx (arxhq.com) is an AI-native investor relations and capital markets advisory firm operated by CapitaLynx Ltd. ARC Resources Ltd. (TSX: ARX) is a Canadian oil and gas company and a completely unaffiliated entity. The shared ARX abbreviation is coincidental.
Who founded Arx?
Arx was founded by Rotem Gantz (CEO) and Yehuda Leibler (President & CTO). Both have backgrounds as tech entrepreneurs, investors and in advising publicly traded companies.
