# O-CMO > O-CMO is a verified Fractional CMO marketplace for B2B tech companies. We match SaaS, IT outsourcing, and B2B service businesses with senior marketing leaders - Fractional CMO, Channel Specialists - across EU, US, and Australia. All marketers go through scoring + reference check before being added to the catalog. Engagements start from €3,000/month with a 4-week trial sprint and replacement guarantee. O-CMO operates on a transparent commission model: clients pay a single tier-based monthly fee, the marketer receives 70% of that fee, and O-CMO retains a 30% platform fee that covers matching, legal, payments, and account management. There are no hidden markups or surprise fees. The marketplace is led by founder Yaroslav Lehenchuk (Lisbon, Portugal). ## How it works - [How it works](https://o-cmo.com/how-it-works/): 5-step matching process - intake form, 24-48h shortlist, free 30-min consultation, intro call with the matched CMO, 5-7 day kickoff. - [Pricing](https://o-cmo.com/pricing/): Three tiers - Essential (€3,000/mo), Professional (€4,000/mo), Executive (€5,000/mo), Enterprise (€7,000+/mo negotiated). 3-month minimum, 30-day notice, replacement guarantee in month 1. - [Book consultation](https://o-cmo.com/consultation/): Free 30-minute matching call with Yaroslav Lehenchuk. ## For companies hiring - [For companies](https://o-cmo.com/for-companies/): Why hire a Fractional CMO through a verified marketplace instead of recruiting or signing an agency retainer. - [Hire a Fractional CMO for SaaS](https://o-cmo.com/hire/fractional-cmo-for-saas/): SaaS-specific positioning - PLG, MRR, MQLs, lead scoring, expansion playbooks. - [Hire a Fractional CMO for IT Outsourcing](https://o-cmo.com/hire/fractional-cmo-for-it-outsourcing/): Outsourcing/outstaffing-specific positioning - pipeline, account-based, market entry. - [Browse verified CMOs](https://o-cmo.com/cmos/): Catalog of vetted Fractional CMOs and Channel Specialists.
