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.
In 2024, the "Data Engineering" service market became saturated. With every IT firm claiming to be a "Snowflake Expert" or "AI Specialist," it became impossible for buyers to distinguish between true expertise and sales fluff.
DataEngineeringCompanies.com was built to solve this. We are an independent research dedicated to mapping the data ecosystem.
Our Core Beliefs
- 1. Rates should be public. The "Contact Us for Pricing" dance wastes everyone's time. We publish estimated rate ranges so you can qualify partners instantly.
- 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. Engineering over Sales. We profile firms on factual attributes — platform certifications, published rates, team size, and case studies — not ad spend. Paid placement never affects inclusion or order.

LinkedIn profileDEC 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 factual, publicly verifiable attributes: platform certifications and partnership tiers, team size, published rate ranges, platform focus, and available case studies. There are no numeric scores and no composite rankings — profiles exist to give you the facts, not a verdict handed down from above.

You can't buy your way onto this list, a higher spot, or a better verdict. Listing and order are never for sale.
A paid "Full profile" just means a firm filled in its full story — it never changes whether we recommend it or how it appears here.
We make money when firms hire our sister agency (100signals) for their own marketing. That revenue comes from work done outside this directory, and it never affects where a firm appears or what we say about them here.
