Jason Barnard

Brand SERP and knowledge-panel consultant

Evidence A

Best for: Brand SERPs, entity identity, knowledge panels and AI brand representation

Schema & semanticAI searchEnterprise SEOFounder of Kalicube

LocationFrance · International

2026 activityIn 2026, Kalicube positions the work around how Google, ChatGPT, Gemini, Perplexity and other assistive engines understand, trust and recommend brands. The current offer combines an advisory methodology, a monitoring platform and client-side implementation rather than promising control over any single search or AI system.

Clients & collaboratorsKalicube Pro publicly displays associations with WordLift, Ahrefs, Holistic SEO, Site Strategics and other practitioners or brands. Kalicube also publishes cases for Merci Facteur, Jason Hennessey and other named entities. The nature, timing and scope of each relationship should be checked before treating a logo as a current consulting client.

Credentials & productsFounder and CEO of Kalicube, author of The Fundamentals of Brand SERPs for Business, creator of the Kalicube Process and architect of Kalicube Pro. His specialist authority is documented through books, extensive publishing, speaking and a proprietary entity-data platform.

Experience & resultsBarnard is an author, international speaker and architect of the Kalicube Process and Kalicube Pro. The platform's September 2026 documentation reports 25 billion data points, 73 million entities and weekly collection since 2015. These are first-party operating figures, so a buyer should still request a comparable case with a baseline, intervention, timeframe and attribution.

Social proofKalicube had a 4.5 out of 5 Trustpilot rating from 20 reviews when checked in September 2026. Barnard also has a substantial specialist publishing, podcast and conference footprint. Audience visibility demonstrates authority, while the Trustpilot sample provides separate company-level service evidence.

Main buying checkTeams mainly seeking low-cost local SEO, routine keyword work, high-volume content or guaranteed control of a Knowledge Panel should choose a different specialist. Buyers without implementation capacity should also clarify what Kalicube will execute directly.

What people sayThe available independent review sample is positive but modest and concerns Kalicube as a company, not Jason alone. First-party testimonials emphasise identity consolidation, Knowledge Panel work and clearer brand representation. Buyers should request two recent references matching their entity type and problem.Separate from the 3.9/5 editorial fit score

What you get2–3 relevant optionsTrade-offs explainedA direct recommendation

Methodology

A ranking should explain its judgment.

Scores are a starting point, not a substitute for fit. Each category changes the weighting so a technical-recovery specialist is not judged like a SaaS growth lead.

35%

Public evidence

Documented roles, case studies, specialist work and verifiable results, not follower count.

30%

Problem fit

How closely the consultant's visible specialism matches the company, problem and intended outcome.

20%

Delivery fit

Whether the buyer needs an audit, advisory, fractional ownership or hands-on execution.

15%

Consensus

Repeated inclusion in current expert comparisons, discounted when a source ranks its own publisher.

Strong public record

Official evidence plus multiple relevant third-party sources or attributable results.

Supported profile

Official evidence plus at least one meaningful corroborating source.

Provisional profile

Identity and specialism are visible, but independent results or reviews remain limited.

Score and publisher disclosure

Dan Akeju created this directory and is included in it. No consultant paid for placement. The 5-point directory assessment is the editorial score divided by 20. Credentials, results, reviews and testimonials receive evidence-coverage scores based on attributable public sourcing. These are not customer ratings or invented outcomes. Age receives 0/100 when no reliable public source exists and is never estimated.
