I get this question from founders at least once a week. They know they need AI help but don't know whether to hire a consultant, bring someone full-time, or try something in between.
The short answer: it depends on your revenue, your AI maturity, and how many hours of AI work you need per week. Here's the long answer with real numbers.
| Factor | AI Consultant / Fractional | Full-Time AI Hire |
|---|---|---|
| Annual cost | $36,000-$60,000 | $180,000-$310,000 |
| Hours per month | 10-20 hours | 160+ hours |
| Time to start | 1-2 weeks | 2-4 months (recruiting) |
| Time to first results | 2-4 weeks | 2-3 months (onboarding) |
| Commitment | Month-to-month or project-based | Full-time employment |
| Expertise breadth | Multi-industry experience | Deep in one company |
| Risk if it doesn't work | Cancel the contract | Severance, re-hiring |
| Available instantly | Yes (within days) | No (months to hire) |
| Knows your business well | Takes 1-2 months | Takes 2-3 months |
| Best for revenue range | $1M-$10M | $10M+ |
| Expense | Cost |
|---|---|
| Monthly retainer (10-20 hrs/month) | $3,000-$5,000/month |
| Or: project-based engagement | $2,500-$15,000 one-time |
| Benefits, equipment, office space | $0 |
| Recruiting cost | $0 |
| Onboarding time | 1-2 weeks |
| Annual total (retainer) | $36,000-$60,000 |
| Expense | Cost |
|---|---|
| Base salary | $150,000-$250,000/year |
| Benefits (health, 401k, PTO) | $20,000-$40,000/year |
| Equipment and software | $5,000-$10,000/year |
| Recruiting (agency fee or time) | $15,000-$50,000 one-time |
| Onboarding time (unproductive weeks) | $10,000-$20,000 equivalent |
| Annual total (year 1) | $200,000-$370,000 |
A full-time AI hire costs 3-6x more than a Fractional AI Officer. The question is whether you need 8x the hours.
Your revenue is $1M-$10M. This is the sweet spot for fractional AI. Big enough to have real problems AI can solve. Not big enough to justify a $250K salary.
You're not sure what AI can do for you. A consultant can audit your operations and tell you where AI will save money before you commit to a full-time hire. Starting with a $2,500 audit is much smarter than posting a $200K job listing.
You need specific projects done. Build a chatbot. Automate lead scoring. Set up inventory alerts. A consultant handles discrete projects, delivers results, and moves on.
You need it now. Hiring a full-time AI person takes 2-4 months. A consultant starts within days. If the pain is urgent, speed matters.
You want to test before committing. A 3-month retainer with a consultant is a $9K-$15K experiment. A bad full-time hire is a $100K+ mistake.
Your revenue is above $10M. At this scale, you likely have enough AI work to fill 40 hours per week. A full-time person is cheaper per hour than a consultant at that volume.
AI is core to your product. If you're building an AI product (not only using AI for operations), you need dedicated, full-time attention.
You have 10+ AI systems running. At that complexity, daily monitoring and iteration needs someone who's fully embedded in your company.
You need 30+ hours per week of AI work. The math flips at roughly 30 hours/week. Below that, a consultant is cheaper. Above that, full-time is cheaper per hour.
The smartest path for most businesses: start with a consultant, then hire full-time when you've outgrown fractional support.
Phase 1 (months 1-3): Hire a Fractional AI Officer. Audit your operations. Build the first 3-5 AI systems. Prove ROI.
Phase 2 (months 4-6): Systems are running. Consultant maintains and optimizes. You're saving $5,000-$15,000/month. Now you know exactly what skills a full-time hire needs.
Phase 3 (months 7+): If AI workload exceeds 20 hours/week consistently, start recruiting. The consultant can help write the job description, interview candidates, and onboard the new hire.
This approach costs less, delivers results faster, and gives you clear data to justify the full-time hire to your board or partners.
Hiring a junior developer and calling them "AI lead." A $90K developer who took an online AI course is not the same as someone who's built and run AI systems in production. You'll spend 6 months figuring that out.
Hiring a PhD when you need a builder. A machine learning PhD is perfect if you're doing cutting-edge research. For business AI (automation, chatbots, data pipelines), you need someone who builds and ships, not someone who publishes papers.
Hiring full-time too early. If you're not sure what AI can do for you, a $200K hire is a very expensive way to find out. Start with a $2,500 audit.
Using a consultant for too long. If you've been on a retainer for 12 months and the workload is clearly full-time, transition to a hire. A good consultant will tell you when it's time to make that move.
| Your situation | Best option |
|---|---|
| "I don't know if AI can help us" | AI Audit ($2,500) with a consultant |
| "I need specific things automated" | Project-based consultant ($5K-$15K) |
| "I need ongoing AI support" | Fractional AI Officer ($3K-$5K/month) |
| "AI is our product" | Full-time AI engineer ($150K-$250K) |
| "We have 10+ AI systems running" | Full-time + consultant for strategy |
Should I hire an AI consultant or a full-time AI employee?
Consultant if: revenue under $10M, specific projects, need results fast, not sure what AI can do yet. Full-time if: revenue above $10M, 30+ hours/week of AI work, AI is core to your product.
How much does a full-time AI employee cost?
$150,000-$250,000 salary plus $30,000-$60,000 in benefits and overhead. Total: $180,000-$310,000/year. A Fractional AI Officer costs $36,000-$60,000/year for the same expertise at fewer hours.
What is a Fractional AI Officer?
An AI expert who works with your company part-time (10-20 hours/month) on retainer. Builds and manages AI systems, trains your team, keeps AI operations running. Same expertise as a full-time AI leader at a fraction of the cost. Best for $1M-$10M revenue companies.
When should I switch from a consultant to a full-time hire?
When three things are true: you need 30+ hours/week of AI work, your AI systems are mature and need daily monitoring, and the institutional knowledge is too deep for a part-timer. Usually happens at $10M-$20M revenue.
