Karhuno AI vs. ChatGPT, Claude, and Perplexity: Why "Big AI" Fails at B2B Sales Signals

We tested the world's most popular AI tools against Karhuno AI using the same sales query. Only one delivered verified, actionable buying signals.

The Experiment: One Query, Four Contenders

Every sales leader wants to know: "Can I just use ChatGPT to find my leads?"

In theory, LLMs like GPT-4, Claude 3.5, and Perplexity can browse the web. They can read news, summarize reports, and answer complex questions. But browsing isn't the same as detecting intent.

We ran a real-world test. We asked Karhuno AI and the "Big Three" general AI tools the exact same query:

The Query

"Find logistics companies in the US that announced new warehouses in the last 30 days."

The Results: Why Timing Requires Specificity

Karhuno AI: Verified Success

Karhuno AI didn't just summarize the news—it provided a list of 10+ specific companies with active expansion signals.

  • 10+ Verified Results (Not Summaries)
  • Live Proof URLs (News & LinkedIn)
  • Sales-Ready Context
  • Decision-Maker Contact Data

The "Big Three": Vague & Stale

ChatGPT, Claude, and Perplexity all followed a similar pattern of failure for this specific sales use case.

ChatGPT

2 vague summaries. No buying signals. No source context.

Claude

4 vague summaries. Hallucinated some dates. No proof.

Perplexity

General industry news. No specific recent warehouse expansion links.

The Conclusion

General AI is great for writing poems or summarizing long documents. But in B2B sales, close enough is not enough.

If you reach out to a company about a "new warehouse" that actually opened two years ago, you lose all credibility. If you reach out without a source URL to prove why you're calling, you're just another cold caller.

Karhuno AI wins because it was built for the SDR workflow, not for chat.
