Modular. Flexible. Built around your needs.
Part-time, project-based, or agency firepower or all at once. You hold the cards.

The missing piece to your puzzle.
From CMO to Head of Growth, our part-time leaders embed inside your team to plan, pilot, and perform evolving with your business as if they’ve always been there.

1+1

Your saviours, when you need them.
You need strategy, execution, and your team available without having to internalize it. The first marketing team by subscription.

On-demand

Fast. Clean. Done.
When you know what you need — and you just need it done.
Positionning, Product Marketing, Event, CRM integrations, Content Strategy… we plug in, deliver, and you take it from there.

Designed around you, because each business  is unique.

We adapt our model to your structure, your rhythm, and your goals. Part-time, agency, or on-demand: built for your reality, not ours.
Startup founder
For the ambitious visionary forced to fill all the gaps, but too unfocused to act everywhere at once.
Scale-up leader
For the C-suite leader who prioritize result-driven execution over traditional methodologies.
SME owner
For the SME leader who manages the vision, not the marketing and expects business growth done right.
Corporate executive
For the executive with the resources to drive change, but the exhaustion of old-school marketing.
Marketer
For the marketing leader burdened by multidisciplinary complexity, who requires specialized firepower to execute at scale.
CRO or VP Sales

We've got you covered
No matter your industry, your position or your current challenges, iytro has a solution to take your marketing to the next level.

The how doesn’t matter. The outcome does.

Your goals shape the mission .
We find the right person, build the team when needed, and set the pace accordingly.
"I need to define a GTM and execute fast. We’re in the middle of a bull run, and it’s now or never."

→ To capture this window of opportunity, we deploy a high-velocity execution model designed for market timing. We initiated with a Fractional CMO to architect the strategy and define the necessary resources. Our Growth and Community specialists then stepped in to analyze, deploy, and test three distinct GTM motions simultaneously, backed by the Part-time CMO. By utilizing data-driven iteration, we identified the winning channel and scaled aggressively. Once the infrastructure was optimized and the trajectory was secured, we recruited and onboarded the permanent team before transitioning out. We don’t just plan; we build the engine, hit the gas, and hand over the keys.

"Our acquisition cost have become prohibitive, we need to improve our growth strategy, refine attribution and tracking, and strengthen the brand to lower our lead costs."

→ To stabilize and reduce your acquisition costs, we deploy a targeted intervention focused on transparency and efficiency. We begin with a Fractional VP of Growth to conduct a comprehensive audit of your existing infrastructure, team performance, and agency output. Simultaneously, we re-architect your attribution and tracking models to ensure total alignment with Finance and core business KPIs. Once the foundation is verified, we integrate a specialized Performance Agency to execute and maintain your campaigns under a rigorous data-governance process. This ensures every dollar spent is tracked, optimized, and directly contributes to lowering your lead costs through disciplined, data-backed growth.

"We’re facing challenges with closing and revenue. We need to strengthen the entire Marketing-to-Sales chain and redefine product marketing to drive stronger growth."

→ To bridge the gap between interest and revenue, we executed a high-impact 3-months project led by a Senior Product Marketing Manager, a Marketing Ops Lead, and a Fractional CMO. We began by gathering deep market intelligence, conducting qualitative persona interviews to map the psychological drivers and decision-making journeys of your buyers. This data allowed us to recalibrate the company’s positioning and refresh all product marketing collateral to align with actual market demand. Simultaneously, we review the Marketing-to-Sales handoff. By re-engineering the CRM workflows, we implemented automated lead-nurturing sequences and enabled the sales team with high-conversion pitch assets. We closed the loop by building real-time attribution dashboards and conducting cross-departmental training to ensure Sales and Marketing operate as a single, unified revenue engine.

"We need to review our entire marketing strategy, restructure an underperforming team, optimize lead generation, work on rebranding and positioning, and execute continuously. Our goal is to build a high-performing marketing engine, then start hiring."

→ We begin with a comprehensive organizational audit of your current personnel and performance, delivering a strategic roadmap. This includes the difficult but necessary restructuring of the department, identifying performance gaps, managing the offboarding of underperforming roles, and leading the recruitment for a new, high-tier team. The Fractional CMO executes directly with the team. We don’t just deliver a plan; we sit at the table to align with Sales, Product, and Finance, reporting directly to the CEO while driving the daily marketing operations. We build the engine from the inside, ensuring the new strategy is fully operational before you commit to a permanent, full-time hire."
