# What Is SQL?

> In sales and venture diligence, SQL usually means Sales Qualified Lead—a prospect vetted by sales as ready for a serious conversation, not merely marketing interest.

**SQL** in startup metrics stands for **Sales Qualified Lead**—a prospect sales has judged worth pursuing, usually against clear criteria.

## How it works

Marketing generates **MQLs** (Marketing Qualified Leads) from content, ads, or events. Sales then qualifies them: budget, authority, need, and timeline—or whatever framework the company uses. An SQL enters the pipeline with an expected close path. Tracking SQL → opportunity → closed-won shows whether top-of-funnel activity converts to revenue.

Investors compare SQL counts to quota, ACV, and sales headcount to sanity-check claims like "pipeline is strong."

## Why it matters

- **Founders:** Define SQL criteria in writing so marketing and sales do not argue about numbers in board meetings.
- **Investors:** Rising MQLs with flat SQLs often means weak qualification or product-market fit issues downstream.

## Common mistake

Confusing SQL with the database language Structured Query Language in a fundraising deck. Context matters; on a sales slide, SQL almost always means leads.

## Related ideas

MQL, pipeline coverage, CAC payback, and sales efficiency.
## When you will see it

Sales-led B2B startups report SQL counts in board decks alongside pipeline coverage and win-rate trends.

## Questions to ask

- What criteria move an lead from MQL to SQL—documented or ad hoc?
- What is SQL-to-close conversion by segment and rep?
- Are incentives aligned so marketing does not inflate top-of-funnel without quality?
## Practical takeaway

Treat **sql** as something to define precisely in writing—not assume everyone in the room shares the same meaning. In term sheets, board decks, and LP updates, tie the concept to a concrete decision: a vote, a price input, a fund policy, or a metric formula. When definitions drift, teams misprice risk, miss leverage, or waste cycles on the wrong conversation.

## FAQ

### What is sql in simple terms?

In sales and venture diligence, SQL usually means Sales Qualified Lead—a prospect vetted by sales as ready for a serious conversation, not merely marketing interest. It is a label you will hear in deal conversations, cap tables, and fund marketing—not abstract theory.

### Why does sql matter?

Investors review SQL volume and conversion when judging go-to-market efficiency. Founders and investors both need a shared definition before term sheets, diligence, or exit talks get serious.
