What is an AI Worker?

An AI Worker is an autonomous AI agent that works like a real teammate: it has a personality, specialized skills and memory, runs tasks end to end and integrates with your tools (Slack, Teams, Gmail, Notion…).

How many AI Workers are available?

15 specialized AI Workers are available, covering marketing, development, design, data, human resources, finance and customer support.

Can I try it for free?

Yes, a free trial is included with no commitment. You can add or remove AI Workers at any time and cancel whenever you want.

Yes. Your data is encrypted end to end, hosted in isolated environments, and never used to train models. Workers Delos is GDPR-compliant and SOC 2-certified.

AI ROI: How to Calculate and Prove the Business Value of AI

By Delos Intelligence — 2026-07-22

Most enterprises struggle to quantify AI ROI. The result: underfunded AI programs, cancelled pilots, and difficulty getting buy-in. Here is a practical framework for calculating and communicating AI business value.

The ROI Communication Problem

A data science team builds an excellent AI model. It reduces processing time by 60%, cuts error rates by 80%, and handles 3x the volume. But when they present this to the CFO, the response is: so what does that mean in dollars?

Most AI teams are excellent at measuring technical metrics and poor at translating them into financial terms. The result is that AI programs get underfunded, pilots get cancelled, and genuinely valuable projects die because nobody could make the business case clearly.

The Four Categories of AI ROI

1. Productivity ROI

The most straightforward category: AI enables people to do more in the same time, or the same work with fewer people.

Formula: (Hours saved per year x Fully-loaded hourly cost) - AI investment

Example: An AI document processing system saves 10 hours per week per employee across 50 employees. At $75/hour fully loaded, that is $1.95 million per year in productivity gain.

2. Cost Reduction ROI

AI reduces direct operational costs: fewer errors (lower rework costs), lower infrastructure costs through optimization, reduced vendor costs.

Formula: (Current annual cost - AI-optimized cost) - AI investment

Example: AI cloud cost optimization reduces cloud spend from $5M to $3M annually, a $2M saving on a $300K AI investment.

3. Revenue Impact ROI

AI generates new revenue or protects existing revenue: better conversion rates, reduced churn, new products enabled by AI.

Formula: (Revenue attributable to AI) - AI investment

Example: AI personalization improves conversion rate from 2.1% to 2.8%, on $50M revenue that is $350K in additional annual revenue.

4. Risk Mitigation ROI

AI reduces the probability or severity of costly outcomes: fraud prevention, compliance violations, security breaches.

Formula: (Expected loss without AI x Risk reduction %) - AI investment

Example: AI fraud detection prevents $2M in annual fraud on a $200K investment. Net ROI: $1.8M.

Building the Business Case

The most effective AI ROI presentations combine all four categories into a total value narrative:

1. Baseline the current state with specific numbers

2. Project the AI-enabled state with conservative assumptions

3. Calculate net ROI across all four categories

4. Show the payback period and confidence level

5. Compare to alternative uses of the same investment

Use ranges, not point estimates. A range of $1.5M to $2.5M with clear assumptions is more credible than a precise $1.97M.

Benchmarks by AI Type

Based on aggregated enterprise implementations:

Process automation AI: ROI payback in 6-12 months, 3-5x return over 3 years
Customer-facing AI: ROI payback in 12-18 months, 4-8x return over 3 years
Decision support AI: ROI payback in 9-15 months, 2-4x return over 3 years
Predictive maintenance AI: ROI payback in 6-9 months, 5-10x return over 3 years
