The Twilio Agency
400+ CDP projects. Top-tier partner status. A decade of turning martech into revenue.
We're growth consultants who know systems—not system integrators who dabble in strategy. Born from Mammoth Growth in 2015, we've spent a decade helping companies turn their martech investments into measurable business outcomes.
How Did GrowthBench Start?
GrowthBench was born from Mammoth Growth, a company we founded in 2015 with a simple mission: help companies grow using modern martech with CDP at the center.
Our founding insight still holds true today: "You don't have the data you need or believe the data you have." Back then, there were only dozens of martech tools. Today there are thousands—and we've built a proven framework to make them work for you.
In 2025, Mammoth Growth split into two focused companies. Mammoth Growth became the leader in agentic data engineering. GrowthBench continued the martech mission—and when Twilio fully integrated Segment in 2026, we went all-in as their top-tier partner.
Today, we're Twilio's leading consulting partner—built on a decade of Mammoth Growth's expertise and 400+ implementations. Same practitioners. Same values. Sharper focus.
Our Journey
The Journey Begins
Founded as Mammoth Growth with a clear mission: help companies grow using modern martech with CDP at the center. Our founding insight—"you don't have the data you need or believe the data you have"—still drives us today.
The Segment Era
Became one of the earliest Segment implementation partners. As the martech ecosystem grew from dozens to hundreds of tools, we helped companies navigate the new paradigm.
Data Warehouse Practice Launches
As companies adopted modern warehouses, Mammoth Growth launched a dedicated practice focused on dbt, Snowflake, and BigQuery—bridging the gap between CDP and data engineering.
Two Companies, Two Missions
Mammoth Growth split into two focused companies: Mammoth Growth became the leader in agentic data engineering, while GrowthBench continued the mission of modern martech excellence.
The Twilio Era Begins
As Twilio fully integrated Segment into their platform, GrowthBench pivoted to focus exclusively on modern martech with Twilio at the center—becoming a top-tier partner with 400+ implementations behind us.
The Principles That Guide Our Work
Infrastructure Over Projects
You don't "finish" data work. You build systems that maintain themselves and scale with your business. We design for the long term.
Execution Over Implementation
Anyone can configure a tool. The value comes from using it to execute your growth strategy. We focus on the outcomes, not just the setup.
Prioritization Over Sprawl
You can't do everything at once. The companies that win focus ruthlessly on what matters most, ship it, learn from it, and move to the next priority. We help you sequence for impact.
Outcomes Over Outputs
We don't measure success by deliverables. We measure it by what changes in your business. If metrics don't move, we haven't done our job.
