The challenge

As ONESONIC transitioned from startup into post-investment operations, they faced the dual challenge of securing funding and preparing for market expansion, including a major UK launch. Like many SMEs, they needed senior-level leadership in finance and marketing, but flexibly, without the burden of permanent hires. The fractional CXO model offered a strategic solution: access to high-calibre executives exactly when and where needed.

Agile Executive case study

Our approach

Strategic finance , Niall O'Kelly, Fractional CFO

Niall began working with ONESONIC in early 2023, initially to support the development of a business plan for Enterprise Ireland (EI) and external investors. With successful grant applications secured, Agile Executives involvement deepened:

  • Business planning & investment readiness: Prepared a robust business plan to secure grant funding and investor interest.

  • Enterprise Ireland engagement: Helped onboard ONESONIC as a High Potential Start-Up (HPSU) client with EI.

  • Corporate finance oversight: Stepped into the role of Fractional CFO in late 2023, focused on managing funding rounds, financial strategy, and ongoing liaison with EI.

  • Team expansion: Introduced additional Agile Executives consultants to provide further expertise across the business.

Marketing leadership , Tim Lion, Fractional CMO

Identified by Agile Executives as a strong strategic fit, Tim joined ONESONIC in January 2025 as Fractional CMO to prepare for the brand's UK launch and a re-launch in Ireland.

  • Brand refresh & strategy: Led a full brand refresh to position ONESONIC competitively in both Ireland and the UK.

  • Operational restructure: Worked with the CEO to redefine internal roles and responsibilities for optimal performance.

  • Agency selection: Oversaw the briefing and selection of a new creative agency, PR agency, and website design partner.

  • Marketing programmes: Developed and implemented an influencer strategy, a performance media plan, and a content strategy executed by ONESONIC's in-house team.

  • Budget optimisation: Ensured maximum ROI from the marketing spend, with KPIs being developed to track broader performance beyond sales.
