Data Engineering Companies Index

Bringing Radical Transparency to Data Consulting

We believe that hiring a data engineering partner shouldn't be a black box. You deserve to know who is good, what they cost, and what they actually specialize in.

The "Data Engineering" service market is crowded. With every IT firm claiming to be a "Snowflake Expert" or "AI Specialist," it is hard for buyers to distinguish true expertise from sales fluff.

DataEngineeringCompanies.com was built to solve this. We are an independent research dedicated to mapping the data ecosystem.

Our Core Beliefs

  1. 1. Rates should be public. The "Contact Us for Pricing" dance wastes everyone's time. We show a firm's hourly rate and minimum project size only when a cited source confirms it, and otherwise mark it not verified, so you know what to ask for in a written quote.
  2. 2. Specialization beats Generality. A firm that does "Everything for Everyone" is rarely the best choice for a complex dbt refactor or a Databricks migration.
  3. 3. Evidence before claims. We profile firms on platform focus, industries, and team-size estimates, show hourly rates and minimum project sizes only when confirmed, and mark which claims we have checked against a primary source. Sponsored placements are clearly labeled and kept distinct from editorial profile data.

The Index is an independent project run by Peter Korpak. His agency, 100signals, handles marketing work for data and software firms — completely separate from what appears in this directory. No other named staff work on the directory.

How we profile firms

Each firm is profiled on platform focus, industries, team-size estimates, and fit guidance. Hourly rates and minimum project sizes appear only when confirmed in field evidence. Claims checked against a primary source are marked confirmed on the profile; the rest are labeled unverified, and an unconfirmed team size is marked not verified. There are no numeric scores and no composite rankings — profiles exist to give you the facts, not a verdict handed down from above.
