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 portal technology via Arx Canvas — built for small-cap and micro-cap issuers on Nasdaq, NYSE American, TSX, and TASE.
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 clients, every Arx client gets senior-level attention, proprietary market intelligence, and access to the same technology platform our advisors use internally.
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. We understand 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, activist detection), Arx Canvas (investor relations website and portal platform with live SEC filing feeds and investor CRM), 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.
What is short interest tracking for public companies?
Short interest tracking monitors how many shares of your company are sold short and how that number changes over time. Rising short interest can signal bearish sentiment or the beginning of a short attack. Arx Terminal provides real-time short interest data alongside options flow and institutional activity so IR teams can respond proactively.
Who founded Arx?
Arx was founded by Rotem Gantz (CEO) and Yehuda Leibler (President & CTO), both of whom have backgrounds as tech entrepreneurs, investors and in advising publicly traded companies.
