Testimonials
“Julia, Maxine, and Aviva are world-class builders with incredible sensitivity to both scientific rigor and commercial objectives. I can't recommend them more highly.
During their time at Yard Stick, they tackled everything from critical operational refactors to expanding our data integrity pipelines and contributing to research that is an asset to the industry as a whole.
They possess a unique 'full-stack' intuition. They understand the high-level business stakes, the scientific know-how to ensure the quality of our data and drive innovative solutions, and the technical requirements to make it all scale. They are fast, collaborative, and consistently deliver interfaces that work in complex field and lab contexts.
Hire them!.”
— Chris Tolles, CEO, Yard Stick PBC
“Aviva and the Terrene team were excellent to work with throughout the process.
They were extremely responsive and quick to turn things around even on short notice, which made a big difference for our timeline. It was clear from the start that they are very knowledgeable in this field, and they took the time to really understand the specific challenges we were dealing with. The strata they produced were high quality and thoughtfully developed, and the collaboration was smooth from start to finish.
We’re also very excited to now have our own software product as a result of this work, which will be incredibly valuable for our program moving forward!.”
