TestBox is first Customer-led software buying platform that makes buying software faster and easier so you can make more confident purchase decisions.

TestBox gives decision-makers a simple way to compare software options side-by-side with data (powered by OpenAI) that looks and feels like theirs.

TestBox was founded in 2020 by Sam Senior and Peter Holland. The company is headquartered in San Francisco, California, with an office in Boulder, Colorado.


TestBox is focused on helping customers test popular customer support software with plans for expanding into sales and marketing tools in the coming months (and eventually into other software categories).


TestBox is launching a new product called TestBox for Sales, which enables them to provide a fully configured trial environment for their prospects.


TestBox's product uses GPT3 technology to build a synthetic dataset based on the types of data that you would find in that particular type of software. So in customer software, that would include customer name, items the customer has bought, the last interactions and so forth.


TestBox is backed by Felicis Ventures, SignalFire, Firstminute Capital, and others. The company raised $10M in an additional Seed financing on Jun 08, 2022. This brings TestBox's total funding to $12.7M to date.
