Our Story

OSER was founded by senior marketing leaders with experience delivering global brand and growth campaigns for ambitious businesses.

Led by Laura Derbyshire and Diego Chicharro, the team brings international advertising, brand and performance marketing expertise, combining strategic thinking with hands-on execution.

OSER works with scaleups and investor-backed companies that need experienced leadership to drive growth without unnecessary complexity.

What Sets Us Apart

Senior leadership, not junior delivery

OSER is led by senior marketing leaders with global advertising and growth experience. We work as strategic partners and fractional marketing leaders, bringing proven expertise to scaleups that need clarity and momentum without building large in-house teams.

Brand and growth, fully aligned

We believe sustainable growth happens when brand, strategy and performance marketing work together. OSER connects positioning, creative and customer acquisition to drive measurable outcomes — not disconnected campaigns or short-term tactics.

AI-enabled, human-led

We use AI to accelerate insight, execution and optimisation, but strategy always comes first. OSER blends human judgment with intelligent tools to help scaleups move faster, make better decisions and scale with confidence.

Commonly Asked Questions

Our turnaround time depends on the scope and stage of the work. Strategic discovery and direction typically takes 2–4 weeks, while ongoing growth and marketing leadership are delivered through monthly partnerships focused on sustained, measurable progress rather than quick fixes.

Our onboarding process is designed to create clarity quickly and align marketing with business goals from the outset. We begin with a focused discovery phase, working closely with founders and leadership teams to understand commercial objectives, growth challenges, customer dynamics and existing performance data. This allows us to identify priorities, opportunities and constraints early on. From there, we define a clear strategic direction and success metrics, agree ways of working, and establish a practical roadmap for delivery. Once aligned, we move into execution and ongoing optimisation, operating as a strategic partner and extension of the team rather than a traditional agency.

We collaborate as strategic partners and an extension of our clients’ leadership teams. Our work is highly collaborative, with direct access to senior decision-makers and clear points of accountability on both sides. We operate through regular working sessions and structured check-ins, focusing on priorities, performance and next steps rather than busywork. This allows us to move quickly, make informed decisions and stay aligned as the business evolves. Our approach is flexible and adaptive, combining strategic guidance with hands-on delivery where it adds value, always focused on outcomes rather than activity.

We’re most interested in working with scaleups and investor-backed businesses that are at an inflection point in their growth. This typically includes projects where teams need clearer positioning, stronger go-to-market strategy, or senior marketing leadership to unlock the next stage of growth. We work well with businesses looking for ongoing strategic partnership, fractional CMO support, or joined-up brand and growth projects.

Our project management approach is intentionally light-touch but disciplined. We agree clear objectives, priorities and success measures at the outset, then manage work through focused planning, regular check-ins and transparent communication. Projects are led by senior team members, with clear ownership and accountability throughout. We adapt our working style to fit each client’s operating rhythm, ensuring momentum, clarity and alignment as priorities evolve.
