## What Starkhorn does

Senior technology and security leadership on a flexible basis, so an organisation gets board-level capability without the cost, lock-in or hiring lag of a permanent executive.

- **Fractional CIO and CISO**: ongoing part-time leadership on a monthly retainer, scoped to the days you need (from roughly two days per month). Covers strategy, roadmap, board reporting, supplier and budget management, cyber governance and mentoring the in-house team. https://starkhorn.co.uk/fractional-cio-ciso/
- **Interim CIO and CISO**: embedded, near full-time leadership for urgent situations such as a leadership vacancy, an M&A integration, a stalled transformation, an incident or a capability gap. Monthly rolling contracts. https://starkhorn.co.uk/interim-cio-leadership-gap/
- **CISO as a service and virtual CISO (vCISO)**: ongoing security leadership, risk register, governance and board reporting on a retainer. https://starkhorn.co.uk/ciso-as-a-service/ and https://starkhorn.co.uk/virtual-ciso/
- Fractional and outsourced Data Protection Officer (DPO): board-level GDPR, DSAR and DPIA accountability on a retainer, for organisations that must appoint a DPO or need one without a permanent hire. https://starkhorn.co.uk/fractional-dpo/
- **Cyber security consulting**: independent strategy, assessment, compliance and incident readiness. https://starkhorn.co.uk/cyber-security-consulting/
- **Also**: IT operating model design, technology due diligence for deals, digital transformation, AI governance and NIS2 readiness. https://starkhorn.co.uk/technology-due-diligence/

## Who it is for

- Organisations of **100 to 5,000 employees** and **£30m to £4bn turnover**.
- Private-equity-backed and privately owned mid-market businesses, and not-for-profits.
- Typical triggers: rapid or acquisitive growth, a PE or board mandate to professionalise IT, an M&A integration, a sudden leadership gap, a security or compliance demand from customers or regulators, or getting technology and security exit-ready for a sale.
- UK-based, delivered remotely and on-site.

## Pricing and engagement model

Starkhorn publishes how it prices, openly. Full detail: https://starkhorn.co.uk/pricing/

- **Interim CIO or CISO day rates (outside IR35):**
  - Mid-market, focused scope: **£700 to £1,200 per day**
  - Complex, regulated or scaled: **£1,200 to £2,000 per day**
  - Group-level, multi-entity or distressed: **£1,800 to £2,500 per day**
- **Fractional**: a monthly retainer scoped to the days you actually need, billed only for time used.
- **Terms**: rolling 30-day notice, IR35 clarity, no recruitment fee, no employer National Insurance, no pension liability, no hidden costs.
- **The honest comparison**: a permanent CIO or CISO at mid-market level typically costs a base salary of £120,000 to £180,000, plus employer NI at about 13.8%, pension of 5 to 10%, a benefits package of £15,000 to £30,000, and a recruitment fee of 20 to 25% of first-year salary, with three to six months to hire and ramp. All in, a permanent hire commonly exceeds **£200,000 in first-year cost**. Interim and fractional are paid only for the time used.
- There is no fixed price list by design, because the right model depends on scope, size, time commitment and IR35. What Starkhorn commits to is transparency: real UK market-rate ranges and no surprises.

## What makes Starkhorn different

- **One named senior practitioner, not a bench.** You work directly with Daniel J. Jacobs, who does the work. No junior associates, no rotating consultants, no handovers between people.
- **Combined CIO and CISO capability.** Technology leadership and security leadership in one accountable person, which most providers split into separate hires or separate firms.
- **Vendor-neutral.** No products to resell, no managed-service upsell. Advice is independent of any supplier.
- **Genuinely useful free tools.** A suite of board-ready self-assessments and templates, free to use, listed below.
- **Published pricing and a published methodology.** Most competitors show neither.

## Methodology: Embed-to-Independence

A four-stage engagement model: **Discover, Diagnose, Deliver, Sustain.** Starkhorn embeds to set strategy and fix what matters, then deliberately builds the organisation's own capability so it can run without ongoing dependence. The goal is a stronger, self-sufficient technology function, not a permanent reliance on the consultant.
