What to Expect from an AI Consulting Engagement
Discovery Phase (1-2 weeks)
Most firms begin with a discovery or assessment phase where they learn about your business, workflows, data, and goals. This phase typically includes stakeholder interviews, workflow mapping, data audit, and opportunity identification.
Strategy and Design (2-4 weeks)
Based on the discovery findings, the firm presents an AI roadmap with prioritized initiatives, architecture decisions, technology recommendations, and estimated timelines and costs.
Implementation (4-16 weeks)
The building phase varies significantly by scope. Simple AI agent deployments can be live in 4 weeks. Complex custom ML solutions with multiple integrations may take 12 to 16 weeks.
Optimization and Handoff (ongoing)
AI systems improve with usage and data. The best firms include an optimization phase where they refine models, tune performance, and train your team to manage the system independently.
Frequently Asked Questions
How do I choose between a big firm and a boutique AI consultancy?
Big firms (EY, BCG, Bain) are ideal for large-scale enterprise transformations where you need governance, regulatory compliance, and global coordination. Boutique firms (BlockNova, RTS Labs, Neurons Lab) are better for mid-market companies that want faster implementation, more direct access to senior consultants, and lower costs.
What should I look for in an AI consulting firm’s case studies?
Look for measurable outcomes: percentage improvements, time saved, revenue generated, costs reduced. Avoid firms that only show logos or describe projects in vague terms. Ask for references you can contact directly.
Is AI consulting worth the investment for small businesses?
Yes, if targeted correctly. Small businesses should focus on high-impact, fast-payback use cases like AI receptionists, customer service automation, or lead qualification. A $10,000 to $20,000 engagement that automates a process consuming 20+ hours per week pays for itself within months.
Can I hire an AI consultant on a project basis rather than a retainer?
Yes. Most AI consulting firms, especially boutiques like BlockNova, offer project-based engagements with fixed scope and pricing. This reduces risk and provides clear deliverables. Retainer models are more common for ongoing optimization and support after the initial implementation.
What questions should I ask during an AI consulting discovery call?
Key questions include: What similar projects have you completed in my industry? What is your implementation timeline for a project like mine? How do you measure success? What happens after the project concludes? Can I speak with a reference client? What is included in the quoted price versus what costs extra?
