advanced
Multi-Threading (Sales)

Building relationships with multiple stakeholders within a target account to reduce deal risk and accelerate enterprise sales cycles.

intermediate
Multi-Touch Attribution

Attribution models that credit multiple marketing touchpoints for a conversion, distributing value across the customer journey rather than to a single point.

advanced
Multi-Turn Reasoning

AI capability to maintain logical coherence and build upon conclusions across multiple conversational exchanges or processing steps.

intermediate
Multimodal AI

AI systems that process and generate multiple types of data simultaneously, including text, images, audio, and video for richer interactions.

intermediate
Multimodal Reasoning

AI capability to reason across text, images, video, and audio simultaneously, understanding relationships between different types of information.

advanced
Multivariate Testing

Testing multiple variables simultaneously to understand how different combinations of changes affect user behavior, more comprehensive than simple A/B tests.

advanced
N
Natural Language Processing

AI technology enabling machines to understand, interpret, and generate human language for applications like chatbots and content analysis.

intermediate
Natural Rate of Growth

The organic growth rate a company achieves without any sales or marketing spend, indicating the strength of product-led demand.

advanced
Negative Churn

When expansion revenue from existing customers exceeds lost revenue from churned customers, meaning the customer base grows even without new users.

advanced
Net Dollar Retention

The percentage of revenue retained from existing customers including upgrades and minus downgrades and churn, with values above 120% indicating strong expansion.

intermediate
Net Promoter Score

A customer loyalty metric from -100 to +100 measuring willingness to recommend, calculated by subtracting detractors from promoters.

beginner
Net Revenue Retention

Revenue retained from existing customers including expansion minus contraction and churn, indicating growth potential without new customers.

intermediate
Network Effects

When a product becomes more valuable as more people use it, creating a defensible competitive moat and accelerating growth over time.

intermediate
Neural Network

Computing systems inspired by biological neural networks that learn to perform tasks by processing examples, forming the basis of modern AI.

intermediate
No-Code AI

Platforms enabling users to build and deploy AI solutions through visual interfaces without writing code, democratizing AI adoption.

beginner

The single metric that best captures the core value your product delivers to customers, aligning all teams toward one measurable outcome.

intermediate
O
OKRs

Objectives and Key Results — a goal-setting framework linking ambitious objectives to measurable key results, popularized by Google.

beginner
On-Device AI

Running AI models directly on smartphones, laptops, and IoT devices rather than in the cloud, enabling offline operation, privacy, and reduced latency.

intermediate
Onboarding Optimization

Improving the new user experience to reduce time-to-value, increase activation rates, and set the foundation for long-term retention.

intermediate
Open-Source LLM

Large language models released with open weights and training methodologies, enabling customization, self-hosting, and community-driven improvements.

intermediate
