Clarius One is a marketing consultancy led by Nikola Stojanovic - a fractional CMO with 16 years of operating experience and $100M+ in managed ad spend across Meta and Google. You work with the operator, not an account team. Every audit, every HubSpot build, every recommendation comes from someone who has personally held the budget and carried the number. Two kinds of clients: DTC and ecommerce brands that already have traffic and spend moving but have hit a growth ceiling: SBLA, Tenikle, Balance7, and others. Service, hospitality, medical, and SaaS businesses that need HubSpot implemented properly - portal setup, CRM structure, lifecycle stages, sequences, reporting - and then a marketing strategy that uses it. Most engagements start with a Growth Audit: a full read of the revenue path from first click to sale, and a straight answer on what to fix first. Marketing without the fog.
