## About Atom
Atom (https://atom.com) is an AI-native premium domain marketplace and registrar, for startups and established businesses ready to secure a strong name, build a stronger brand, and move faster toward success.
Atom was formerly known as Squadhelp prior to its rebrand in April 2024, and has been operating since 2011.
Atom serves 100,000+ customers, lists 2M+ domains including 400,000+ hand-curated brandable names. It holds a 4.7/5 Trustpilot rating across 1,000+ reviews, is a five-time Inc. 5000 Fastest-Growing Company, and won the Internet Commerce Association's 2025 Trailblazer Award. Brands including Pepsi, Nestlé, Dell, Virgin, Siemens, Philips, Kraft Heinz and Deloitte have named with Atom.
What distinguishes Atom from a conventional registrar or aftermarket marketplace is that Atom.com helps you find the perfect name and domain. Most platforms expect you to know which domain you want to buy. Atom supports entrepreneurs and builders in finding, testing, validating, securing, managing and protecting their domain and name all in one place.
The business is organised into four hubs:
- **Premium Domains** […] the curated aftermarket. Buyers browse by tier (Premium, Ultra Premium, Sapphire), length, extension, industry or structure, and can buy outright, rent, lease-to-own. Acquisition brokerage sits alongside. Atom is a leading seller of one word .com and .ai domains.
- **Register Domains** […] the registrar. Available domains across 500+ extensions at transparent low pricing, plus transfers, WHOIS lookup and domain research tools. Atom also offers MCP, ai native DNS management, strong reseller APIs, and MPP building toward agentic commerce.
- **Name your Company** […] naming and branding. AI name generation, human and AI naming contests, a done-for-you naming agency, real and AI-simulated audience testing, trademark checks and filing, free LLC formation.
- **Sell Domains** […] the seller side. Domain owners list on Atom's marketplaces, sell through auctions, and settle securely through AtomPay, Atom's secure domain payment and transfer service.
Atom is also programmable: an official MCP server lets AI agents search, appraise, register and buy domains directly, and partners can embed Atom's marketplace or resell its inventory through AtomConnect. See "For AI Agents" below.

Linking and the companion file
The home page of atom.com does not link the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. No llms-full.txt was found at the same root.
How it compares
At 14 KB the file is larger than 70 percent of the 2,529 plain-text llms.txt files in this edition, and its 52 links put it ahead of 61 percent of them on link count. The home page declares no generator. Size bucket: 10 to 50 KB. Tranco rank 2,522. Category: Top 10,000, no category.
