Fractional CMO

What Fractional CMO does

OTReniX, doing business as Fractional CMO, is a London-based B2B marketing agency founded in 2020 that provides part-time senior marketing executive services to growth-stage technology startups. The company is led by founder Dmitrii Gavrikov, who brings 20+ years of B2B tech marketing leadership experience from Cisco, Kaspersky Lab, and Siemens, and has served 50+ startups from idea through scale. Its core offering is a fractional CMO engagement model delivered at 10-25 hours per week across three subscription tiers priced at $6,000, $9,000, and $15,000 per month, targeting Seed through Series B startups ($0-25M ARR) in B2B SaaS, cybersecurity, and industrial verticals.

The service encompasses seven responsibility areas: positioning and messaging, GTM strategy and roadmap, demand generation, team hiring and coaching, sales-marketing alignment, marketing operations and tech stack integration, and board/investor reporting. No proprietary technology platform is offered — the company delivers strategic advisory and execution oversight using third-party tools (HubSpot, Salesforce, Webflow) on the client side. Engagements require a 3-month minimum commitment and then operate month-to-month, typically running 12-24 months, positioning the service as a cost-efficient bridge to a full-time CMO hire.

The business is founder-controlled with 1-10 employees, no disclosed institutional capital, and a direct-to-founder sales motion via website consultation bookings and content marketing. The firm claims quantified client outcomes including 3× pipeline lift within 6 months, -35% CAC reduction, 85% average revenue growth across clients, and case studies reaching $1.2M ARR from $0 in 12 months. Geographic footprint spans EMEA, NA, and APAC based on founder prior experience and client engagements, though no local entities are established.

Direct peers

• The CMO Alliance: Fractional CMO network providing part-time and interim marketing leadership to B2B tech companies. Operates in the same 'fractional executive' category with overlapping buyer profiles (Series A-B startups).
• Chief Outsiders: Largest US-based fractional CMO firm with a network of 100+ fractional CMOs serving mid-market and growth-stage companies. Direct competitor in the same fractional CMO category with similar retainer-based engagements.
• Catalant: Marketplace connecting companies with fractional consultants and operators for project-based engagements. Comparable business model of selling senior expertise on a fractional basis, though broader in scope than marketing.
• Boardroom Insiders: Fractional executive placement firm focused on placing senior operating leaders (CMOs, CROs, CFOs) into growth-stage companies. Directly comparable delivery model for interim executive engagements.
• B2B Marketing Agency (boutique competitors) — e.g., Kalungi: Boutique B2B marketing agency providing fractional CMO and full-service marketing to SaaS startups. Closely comparable in service offering, pricing model, and target customer segment (Seed to Series B SaaS).

Emerging players

• Revenue Collective: Membership-based community for CMOs and revenue leaders at growth-stage companies, offering peer learning and talent matching. Adjacent to the fractional CMO category with overlapping buyer segments and content-led GTM.
• Pavilion: Membership and talent platform serving CMOs and revenue leaders at high-growth companies, formerly known as CMO Summit. Comparable buyer base and content-driven GTM approach.

Broad incumbents

• Toptal: Large fractional talent marketplace covering marketing, design, and engineering. Overlaps with OTReniX's value proposition of providing senior marketing expertise without full-time hire, though much broader in scope.

Others
