WHEN TO CHOOSE

Which option fits your situation?

Choose an AI Consultant when

  • You need speed and flexibility without hiring full-time
  • You want a roadmap that connects AI to business outcomes
  • You need someone to bridge business, data, and engineering teams

Choose an AI Agency when

  • You have a well-defined project with clear deliverables
  • You need a specialist team for a short-term execution
  • You already have a strategy and need hands to build it
  • You prefer a fixed-price or retainer engagement model

Build In-House when

  • AI is core to your product or competitive advantage
  • You have the budget to attract and retain AI/ML talent
  • You need daily, deep domain iteration on models
  • You have enough data and engineering maturity internally

FAQ

Common questions about AI consulting

Should I hire an AI consultant or build an in-house AI team?

Hire an AI consultant when you need speed, objectivity, and cross-industry experience without long-term headcount. Build an in-house team when AI is core to your product and you have the budget to attract and retain AI talent.

What is the difference between an AI consultant and an AI agency?

An AI consultant diagnoses problems and designs a strategy-first roadmap. An AI agency typically executes specific projects under a retainer or project fee. A consultancy focuses on business outcomes and vendor-neutral advice; an agency often focuses on delivery and billable hours.

How much does an AI consultant cost in Singapore?

AI consultants in Singapore typically charge S$150–500 per hour or S$10k–50k+ for fixed-scope audits and roadmaps. Monthly advisory retainers range from S$5k–15k. In-house AI hires can cost S$8k–20k+ per month before tools and infrastructure.

Can an AI consultant also implement the solution?

Yes. Many AI consultancies, including ZGaze Digital, offer end-to-end services: diagnose the opportunity, design the solution, build the integrations, and run optimisation. This avoids the handoff gap between strategy and execution.
