AIDOLS 90-Day Build vs Traditional Consulting
Published · Updated · AIDOLS Research Team
The AIDOLS 90-day engagement is the Build tier: a $75K–$150K fixed fee, a first measurable result in 2–3 weeks and a production deploy at 90 days with a 40%+ efficiency target. Traditional consulting bills hourly, phase by phase. If the deployed system does not generate ROI exceeding its fee within 90 days, the fee is refunded in full.
| Dimension | AIDOLS 90-day engagement | Traditional AI consulting |
|---|---|---|
| Timeline | First measurable result in 2–3 weeks; production at 90 days | Often several quarters, phase by phase |
| Fee | Fixed: Build $75K–$150K | Time and materials; Big Four benchmarks $400–$800/hour, MBB $500–$1,000+/hour |
| Guarantee | Build fee refunded in full if the deployed system's ROI does not exceed its fee within 90 days | Rarely advertised; negotiated per contract |
| Team | Small senior engineering team that builds what it scopes | Sized to the program; often separate strategy and delivery teams |
| Primary output | A system in production, measured against an agreed baseline | Assessments, strategy, roadmaps and implementation support |
| Your team's involvement | Interviews, access, sign-off on the baseline and handover | Heavy: your team executes the recommendations |
| Risk allocation | AIDOLS carries the fee risk | Client carries the delivery risk |
Most AI consulting engagements follow a familiar script: months of assessment, a strategy document, phased implementation recommendations, and a final invoice that is hard to connect to a measurable outcome. The AIDOLS 90-day engagement (the Build tier on the pricing page) was designed as a direct alternative: fixed fee, fixed timeline, a working system and a written guarantee.
This comparison lays out how the two approaches differ so you can decide which fits your business. For the wider model behind it, see what AI-native consulting is.
What you're comparing
Traditional AI consulting (large strategy firms, the Big Four, systems integrators and many boutiques) follows an advisory model. A team assesses, develops strategy, recommends technology and guides your team through implementation, billed on time and materials. Market rate benchmarks run from $150–$300 per hour for boutique firms and $300–$500 for mid-tier firms to $400–$800 for the Big Four and $500–$1,000+ for MBB firms (see the AI consulting cost guide). Outcome guarantees are rarely advertised.
The AIDOLS 90-day engagement is engineering-first. A small senior team maps how the workflow actually runs, gives a written verdict on what each bottleneck needs (software, a process change, or AI), and builds and deploys AI where it pays, in your environment, within 90 days. The fee is fixed at $75K–$150K. For a Build, if the deployed system does not generate ROI exceeding its fee within 90 days, the fee is refunded in full.
When to choose the 90-day engagement
- You need a working system, not a report. The output is a deployed system measured against an agreed baseline, not a roadmap your team has to execute over the next year.
- Budget certainty matters. A fixed fee means you know the total before signing.
- You can't wait several quarters. The first measurable result lands in 2–3 weeks and the production deploy at 90 days, with a 40%+ efficiency target on the scoped workflow.
- You want accountability in writing. The refund guarantee puts the fee at risk, not your budget.
- Your team is stretched thin. The system integrates with your existing tools; your team provides interviews, access and sign-off, not a project office.
When to choose traditional consulting
- You need organizational change management. If the primary challenge is cultural (getting teams to adopt new ways of working, restructuring departments), a consulting firm's change-management expertise is valuable.
- You want to build an internal AI team. Traditional firms can help you hire, train and structure an internal data science or ML engineering function. The 90-day engagement builds a system; it does not build your bench.
- The problem is strategic, not operational. Whether to enter a new market, acquire a company or restructure your technology organization is strategy work.
- Regulatory complexity needs established relationships. In heavily regulated industries, a firm with long-standing regulatory relationships can be the right choice for the parts that need human judgment and a recognized name.

The cost reality
| Cost component | Traditional consulting | AIDOLS 90-day engagement |
|---|---|---|
| Assessment | Billed by the hour, often its own phase | Included; or a standalone Sprint at $15K–$25K |
| Strategy and roadmap | Billed by the hour, often its own phase | The written verdict is part of the engagement |
| Build and implementation | Billed by the hour, or by your own team | Included in the fixed fee |
| Total cost | Depends on hours and duration | Fixed: $75K–$150K |
| Outcome terms | Rarely advertised | Full refund of the Build fee if the deployed system's ROI does not exceed its fee within 90 days |
| After go-live | You build, run and maintain | Handover with monitoring and runbooks; optional Scale at $25K/month |
The gap widens with time. Every month spent in assessment and strategy is a month the workflow keeps running the old way.
What "a system in production" actually means
Traditional consulting produces deliverables: assessments, strategies, architecture diagrams, vendor evaluations, implementation roadmaps. They are useful inputs, but they do not generate value on their own. Your team still has to build, deploy and operate the system, and that execution gap is where many AI implementations stall.
The 90-day engagement produces a working system in your environment, connected to the tools the work already runs in, processing your actual data, and measured against the baseline agreed at the start. Typical scopes are operational: intake and triage, document processing, exception handling, reporting that someone currently assembles by hand.
The system is handed over with monitoring, runbooks and documentation. Clients who want AIDOLS to keep operating and extending it can move to the Scale tier.
The guarantee question
Traditional consulting firms avoid guarantees for a structural reason: their output is advice, and the success of that advice depends on your execution. See why traditional AI consultants cannot guarantee results for the full argument.
AIDOLS can put its fee at risk because it controls the delivery chain on a narrow scope: it maps the workflow, agrees the baseline, builds the system, deploys it and measures it. The 40%+ efficiency figure is the production target measured at day 90. The guarantee is the refund: for a Build, if the deployed system does not generate ROI exceeding its fee within 90 days, the fee is refunded in full. See fixed-fee AI consulting for the complete terms.
Making the decision
Ask yourself three questions:
- Do I need advice or a working system? If you need someone to tell you what to do, hire an advisor. If you need one workflow running differently within a quarter, choose the 90-day engagement.
- Can I wait several quarters before seeing results? If yes, a traditional program is a viable path. If not, the 90-day engagement is the faster route.
- Am I paying for effort or for results? Time-and-materials billing pays for time regardless of outcome. A fixed fee with a refund guarantee pays for a result.
For most mid-market companies, the 90-day engagement delivers more value, faster, with less risk. The traditional model still has a place, particularly for large enterprises managing complex organizational change, but it no longer has to be the default for companies that want AI in production rather than on a roadmap.
