OSER works with scaleups and mid-size growth businesses where growth has moved beyond experimentation and into complexity.

Typically Series A+ and £10–£50m+ revenue, our clients are founder- or CEO-led teams navigating pivotal moments - growth plateaus, brand dilution, investor pressure, or the need for senior marketing leadership that operates at board level.

If growth decisions feel too important to be left to tactics alone, OSER is usually a strong fit.

OSER is a strategic growth consultancy that works at leadership level, not an execution agency.

We start by clarifying vision and priorities with founders and CEOs, then support focused execution where it counts = often through advisory or fractional leadership. The goal is momentum and outcomes, not activity.

OSER isn’t the right fit for businesses looking for outsourced execution or quick, low-cost delivery.

We work best with founders and leadership teams who value strategic thinking, are open to challenge, and recognise that clarity at leadership level is an investment - not a shortcut - to sustainable growth.

OSER works exclusively with scaleups and growth-stage businesses.

Typically, this means companies with:

• Proven product–market fit

• Significant commercial traction

• Leadership teams operating at board and investor level

• Revenues in the £10m–£50m+ range, or

• Well-funded Seed or Series A businesses already in active scale mode

We are not designed for early-stage experimentation, MVP development, or hands-on startup execution.

Our work is focused on helping leadership teams:

• Create strategic clarity at scale

• Align brand, marketing and growth decisions

• Build credible, investable growth narratives

• Navigate complexity as organisations grow

If your business is past the “what are we building?” phase and into the “how do we scale this well?” phase, OSER is likely to be a strong fit.

Yes. OSER works with private equity, venture investors and portfolio company leadership teams where growth, brand and marketing decisions directly impact enterprise value.

We’re typically brought in at moments of change - post-investment, pre-exit, during repositioning, or when performance needs clearer strategic direction.

Our role is to create clarity, alignment and commercial momentum at leadership and portfolio level - not surface-level brand activity.

OSER works across both B2B and B2C. Our focus is on growth-stage businesses dealing with complexity - whether that’s long sales cycles, multiple stakeholders, or scaling consumer demand.

The principles we apply - clarity, positioning and strategic focus - matter far more than sector.
