Tabby Stack is a data engineering consultancy built by practitioners. We grew from a simple observation: companies need senior data help, and they need it fast.
Senior specialists only. No juniors learning on your dime.

Your team owns everything at handoff
We operate as a lean core team supported by a vetted network of senior contractors. We don’t scale with junior associates. We scale by matching the right senior specialist to the right problem. It’s a model that keeps quality high and overhead low, and we pass those savings directly to you.
If your team can’t maintain it without us, we haven’t done our job.
We measure success by business results, not hours logged or lines written.
Every engagement ends with a handoff. Your team owns everything we build.
We listen first, then prescribe. Not every problem needs a new tool.

dbt Labs
Certified Partner
Using dbt since 2017, when it was still in Fishtown.
The Fishtown connection is real. Our founder was literally down the street from Fishtown Analytics (now dbt Labs) in Philadelphia when dbt was a command-line tool with a handful of users. Tabby Stack started as a pandemic side project in 2020. Companies kept calling for the same thing: senior data help, fast, without the overhead of a Big Four engagement. What started as one freelancer grew into a network of senior specialists who share the same philosophy: build clean, document everything, and make yourself replaceable.
