Description

Fifth Dimension is seeking a Head of Growth to shape the company's next stage. The successful candidate will own the growth strategy and work with the founders and leaders across sales, product, and customer success to translate it into a clear go-to-market plan.

The role involves making choices about which customers and use cases to prioritize, what makes the proposition compelling, and where to invest time and money. The remit spans the customer journey, from awareness and demand through to conversion, adoption, and expansion.

Key responsibilities include:

  • Owning a growth strategy and go-to-market plan tied to company revenue goals
  • Identifying segments, buyers, use cases, and markets with the strongest opportunity
  • Working with customers, sales, and product to sharpen positioning, messaging, and evidence of customer value
  • Building a prioritized program of GTM experiments across target segments, messaging, channels, and sales approaches
  • Defining what each experiment should teach and how to judge it
  • Deciding what to scale, adapt, or stop
  • Partnering with sales on opportunity quality and conversion
  • Setting growth targets and connecting activity and spend to qualified opportunities, pipeline progression, revenue, and acquisition efficiency
  • Establishing a regular GTM review with leadership
  • Building the growth function, coordinating execution, and proposing the budget, hires, and external support needed

The ideal candidate has experience in setting and delivering growth or GTM strategy for an early-stage or scaling B2B software business, with evidence of contribution to pipeline and revenue. They should be able to think commercially, bring a strong bias towards experimentation, and be willing to change direction when the evidence warrants it.

The compensation package includes a salary of £100,000-£140,000, plus bonus and equity.
