# Enrichment processors

These processors fill your grid with company and contact data from outside providers. Most need that provider's [credential](/connected-apps/overview) on the column.

## Company data

* **PitchBook Company Summary** returns profile data like headcount and financing status, with **Private Company Financials** and **Latest Financing** for deeper financial detail.
* **Glassdoor Ratings** and **Trustpilot Ratings** pull employer and customer review scores, no credential needed.

## Contact data

* **Apollo Get Contact** finds a person's work email and profile details.
* **RocketReach Get Contact** finds emails, phone numbers, and social links.

## Email verification

* **Verify Email** checks whether an address is valid before you send to it. It comes in two versions, one under **MillionVerifier** and one under **ZeroBounce**, use whichever provider you have.

<Tip>
  Chain providers with the [Waterfall processor](/grids/processors/advanced) so each row only spends [credits](/getting-started/plans-and-credits) on the sources it actually needs.
