OSER is a London-based growth marketing consultancy working with scaleups, founders, CEOs, and investors to turn strategy, brand, and marketing into measurable growth.
Growth Marketing Consultancy for Scaleups
We sit between strategy and execution, helping leadership teams make better decisions about where to focus, how to grow, and how marketing supports long-term value creation.
This is not agency marketing. And it’s not short-term growth hacking.
It’s senior-level growth thinking, applied with commercial discipline.
What we mean by “Growth Marketing Consultancy”
Growth marketing is often confused with performance marketing, paid acquisition, or tactical optimisation. A growth marketing consultancy is different.
At OSER, growth marketing means:
-
Defining where growth should come from before deciding how to pursue it
-
Aligning brand, marketing, sales, and leadership around the same priorities
-
Making trade-offs explicit: what to do now, what to stop, what can wait
-
Ensuring marketing decisions stand up to board-level and investor scrutiny
We work upstream of channels and campaigns, bringing clarity to direction, structure, and decision-making, then supporting execution where it matters.
How OSER is different from agencies and growth shops
Most growth marketing agencies are built to deliver activity. OSER is built to deliver clarity.
Agencies focus on execution: campaigns, channels, optimisation, delivery, and growth marketing consultancies focus on direction: strategy, prioritisation, and leadership alignment. OSER utilises creative thinking, but always starts with the thinking.
We work with leadership teams to define:
-
The real growth problem (not just the symptoms)
-
The role marketing plays in the next phase of the business
-
How brand and performance work together, not against each other
-
What success actually looks like - commercially, not cosmetically
Who is this for
Our growth marketing consultancy work is designed for scaleups, typically:
-
£10m–£20m+ revenue
-
Post-product-market fit
-
Founder-led or founder-transitioning businesses
-
Investor-backed or preparing for funding / PE involvement
-
Experiencing complexity, slowdown, or strategic drift
Common situations we support:
-
Growth has plateaued despite increased spend
-
Marketing activity is high, but the impact is unclear
-
Confusion between brand vs performance priorities
-
Leadership disagreement on direction or focus
-
Preparing for a senior hire (CMO / Head of Growth)
-
Pressure from investors to show clearer momentum
What a Growth Marketing Consultancy actually delivers
Our role is to help leadership teams step back, regain clarity, and move forward with confidence. As a growth marketing consultancy, OSER works across:
-
Growth strategy and direction
Defining where growth should come from and why. -
Brand and positioning for scale
Clarifying narrative, value, and differentiation as the business matures. -
Marketing structure and leadership clarity
Helping founders decide who to hire, when, and how roles should work together. -
Demand, performance, and prioritisation
Making sense of channels, spend, and return, without vanity metrics. -
Investor and board alignment
Ensuring marketing supports valuation, confidence, and long-term value creation.
This work often leads into fractional CMO support, strategy sessions, or leadership advisory, but the consultancy lens always comes first.
How this connects to OSER’s wider work
Our growth marketing consultancy approach underpins everything we do at OSER, including:
-
Fractional CMO support - executive-level leadership when a full-time hire isn’t right yet
-
Strategy Sessions & OSER Flow Retreats - focused clarity and alignment for leadership teams
-
Private Equity & Portfolio Growth - supporting investors and boards across multiple businesses
-
Insights & Thought Leadership - challenging assumptions around growth, marketing, and leadership
