By Kamil Banc | April 16, 2026

## Claims

1. **20,000 Employee-Built AI Tools** (source summary): BBVA employees built 20,000 AI tools in 18 months through a bottom-up enterprise adoption approach.
2. **Framework Published in HBR** (source summary): BBVA's five-move AI adoption framework was published in Harvard Business Review as a replicable playbook.
3. **The Policy-Behavior Gap** (source summary): Many companies officially ban AI tools while employees secretly use them, creating a policy-behavior gap.
4. **Largest European Bank AI Programme** (source summary): BBVA built the largest bottom-up enterprise AI programme in European financial services.
5. **Most Replicable Regulated-Industry Playbook** (Kamil's interpretation): Kamil Banc considers BBVA's playbook the most replicable enterprise AI approach for regulated industries.

## Evidence

### Quote
> "That gap between the official policy and the actual behaviour is the whole game." - Kamil Banc

### Key Statistics
- **20,000**: Number of AI tools built by BBVA employees through the bank's bottom-up adoption programme
- **18 months**: Timeframe in which BBVA employees built the 20,000 AI tools
- **Five moves**: Number of steps in BBVA's AI adoption framework, which was published in Harvard Business Review

## Context
The article examines BBVA's enterprise AI adoption strategy, highlighting how a bottom-up approach enabled employees to build 20,000 AI tools in 18 months. The author, Kamil Banc, draws on his experience advising US companies on AI culture to frame the common tension between official AI bans and actual employee behavior. BBVA's five-move adoption framework, published in Harvard Business Review, is presented as a transferable model for organizations in regulated industries. Practitioners can apply the key insight that closing the gap between formal policy and real employee behavior is central to successful enterprise AI adoption. However, the article's full framework details are behind a paywall, so readers should consult the referenced HBR publication for complete methodology.
