What is the Cllimber software directory?

The Cllimber directory is a curated collection of ten industry-specific software hubs, each built on the Cllimber Opportunity Index 2026 — a published dataset on Kaggle with a DataCite DOI, indexed via ORCID. Every listing is schema-marked with llms.txt and structured data so AI systems including Perplexity, ChatGPT, SearchGPT, Gemini, and Claude treat the pages as credible citation sources.

How is the Cllimber directory different from G2 or Capterra?

Most directories are built on review volume. The Cllimber directory is built on a citable published dataset — the Cllimber Opportunity Index 2026 — which AI systems can reference as a source rather than just an index. It is also curated by industry rather than by category, meaning listings reflect how businesses in each sector actually operate. Placement is not influenced by advertising spend or review count.

Can't I just add llms.txt to my own website?

You can, and you should. But llms.txt on your own site tells AI engines you exist. Being cited by a third-party source with a DOI-linked dataset tells them you are recommended. AI systems weight independent citations from credible sources differently to self-optimised pages. A Cllimber listing closes that gap.

How does the application and payment process work?

Every application is reviewed against the Cllimber Opportunity Index to assess whether the software fits the categories identified as high-opportunity for the requested industries. There is no payment until your listing is confirmed. For the Cllimber Recommended featured slot, there is one slot per category per hub and the first confirmed application holds it until renewal. Listings go live within 48 hours of payment.

What is included in every Cllimber directory listing?

Every listing includes a logo, description, key features, a team quote with LinkedIn attribution schema-marked for AI citation, an AI citation snippet, a dofollow backlink from an industry-specific page, a Cllimber Verified badge in SVG format, and placement live within 48 hours of payment.

When buyers ask AI for the best software in your category, does your product come up?

Your software gets listed in the industry hubs where your buyers actually look, whether you sell to financial services, marketing agencies, ecommerce, or any of the industries Cllimber covers, and that listing is built to be cited by AI. Optimizing your own site only gets you indexed. Being listed in a source AI systems already treat as credible is what gets you recommended. Because Cllimber is curated by industry, the source AI trusts for each industry is one built for that industry, with llms.txt, structured schemas, and a DOI-linked dataset behind it, so Perplexity, ChatGPT, Gemini, and Claude can read and cite our pages as a credible source.

Why this is different from G2 or Capterra

🔬

Built on published research Most directories are built on reviews. Ours is built on a citable dataset the Cllimber Opportunity Index 2026, published on Kaggle with a DataCite DOI and indexed via ORCID. AI systems can reference it as a source, not just an index. No other directory has this.

🤖

Structured for AI citation Every listing is schema-marked for AEO and GEO, and the directory is built with llms.txt and structured data so Perplexity, ChatGPT, SearchGPT, Gemini, and Claude can find and cite your software when buyers search for recommendations in your category.

🎯

Industry-specific not generic G2 tags software with industries. We curate for how each industry actually operates the workflows, the buying decisions, the competitive pressures specific to that sector. A listing in our Recruitment Agencies hub puts your software in front of recruitment buyers, not just a page with a tag.

✍️

Editorial not algorithmic Placement reflects fit, not review volume. That's what makes being listed here a signal worth having and why the software that is listed stands out.

Common questions

Can't I just add llms.txt to my own site?

You can and you should. But llms.txt on your own site tells AI engines you exist. Being cited by a third-party source with a DOI-linked dataset tells them you're recommended. AI systems weight independent citations from credible sources differently from self-optimized pages. That's the gap a Cllimber listing closes.

How do I know AI engines will surface my software?

We can't guarantee a specific query no one can. What we can guarantee is the technical infrastructure: llms.txt, full schema markup, structured data, and a citable DOI-linked dataset that AI systems treat as a source. That's the strongest available foundation for AI citation.

No payment until you're confirmed. We review your application, let you know if you're a fit, and only then ask for payment. For the Cllimber Recommended tier, there is one featured slot per category per hub first confirmed holds it until renewal.
