# Semantic layers (2026 reboot)

> BI semantic layers, redesigned for LLM-driven exploration.

**Sector**: [Data Infrastructure](https://signals.gitdealflow.com/niche-down/data-infrastructure)  
**Build cost**: One-quarter build  
**Deal velocity**: Steady — one deal per month

## Why now

Every BI vendor is racing to ship AI. Most fail because they lack a semantic layer. The standalone product is real.

## What the signal looks like

Repos with dbt / Cube.dev compatibility, LLM-query interfaces, and BI-tool integrations.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Cube.dev shape
- MetricFlow / Transform shape
- Open-source semantic layer libraries

## What this displaces

A Looker LookML file that one person understands.

## Our build-vs-invest call

Hard but durable. Fund only with prior BI or data-modeling background. The moat is the semantic-graph + the BI integrations.

## Frequently asked

### Buyer?

Data + analytics leaders at mid-market companies.

### Pricing?

$1-5k/mo per organization.

### Defensibility?

Semantic graph + LLM-query accuracy + ecosystem.
