At Deep Blue, we offer both through our GC On Demand and Legal On Demand services. These are flexible, fast-to-deploy solutions tailored to your stage, your risk profile, and your budget.

Both models are adaptable, and they can serve different needs. Here’s what you need to know:

What’s the Difference?

Fractional Legal Support

A part-time lawyer - often a former GC or senior in-house counsel - who integrates with your team and supports you over the long term. Typically 10-20 hours per week.

  • Ideal for: Ongoing legal needs when you don’t have headcount for a full-time hire.
  • Profile: Strategic, senior, and commercially minded
  • Length: 6+ months, flexible and scalable
  • Structure: An on-demand. flexible solution

You get continuity, strategic input, and legal support that scales with your business.

Interim Legal Support

A full-time legal professional for an agreed timeframe - covering a specific absence, workload spike, or urgent need.

  • Ideal for: Parental leave, team gaps, special projects, or transactions
  • Profile: Plug-and-play in-house lawyers from senior level to GC
  • Length: 3–12 months (or longer if needed)
  • Structure: Usually 3-5 days per week

You get a quick injection of legal resource to cover a defined gap.

Why It Matters

Legal hiring isn’t always linear. Sometimes you need high-calibre support fast, without locking in a long-term hire. Other times, you need someone strategic, but not full-time.

That’s why we built GC On Demand and Legal On Demand - to help founders, COOs, and legal leaders access flexible legal talent at every stage of growth.
