Our Story
Built by Those Who Understand
The Beginning
TallyFlex was born from firsthand observation of the data collection challenges in ABA therapy. As a software engineer with deep connections to the ABA community, I witnessed the daily struggle of passionate BCBAs and RBTs trying to balance comprehensive data collection with meaningful client interaction.
The Problem
Evening after evening, I observed dedicated therapists spending hours wrestling with paper data sheets, crashed spreadsheets, and clunky software. The irony was painful: in a field where data drives every decision, the tools for collecting that data were failing the very professionals dedicated to helping children with autism.
The Catalyst
The breaking point came when an entire week of behavioral data was lost due to a corrupted file. Watching a therapist recreate that data from memory at 11 PM, I realized that adaptation to poor tools wasn't innovation. With 15 years building enterprise data systems, I knew we could do better.
The Mission
TallyFlex was built with one question in mind: What would give behavioral health professionals their time back, so they can focus on changing lives? Today, we serve over 10,000 ABA professionals who no longer have to choose between comprehensive data collection and meaningful client interaction.
