$200,000 USD + Equity & Benefits About TestBox
TestBox was founded with a bold mission: to fundamentally transform how software is bought and sold.
Today, most enterprise software is still sold through static demos and slide decks. TestBox replaces that with real, interactive product experiences powered by synthetic data, intelligent orchestration, and our proprietary product graph. Instead of imagining how software might work, buyers can actually test it in realistic environments before they buy.
We've raised
$27M in funding to date , with
Airtree leading our Series A
and participation from
Skip Capital, Glitch Capital, K8, and SignalFire . This funding allows us to accelerate our vision of building the infrastructure that powers modern software transactions.
To share more about the vision for TestBox and the product direction ahead, our CEO recently announced the Series A and several new product developments.
Watch the announcement here.
At TestBox, we're not just improving demos. We're creating the next generation platform for how software is evaluated, purchased, and implemented, enabling teams to move from first interaction to successful onboarding faster and with greater trust.
We're a fast-growing startup built by a team that values experimentation, velocity, and customer impact, and we're just getting started.

Design and implement the suite of robust backend services that form the foundation of our new platform, ensuring they are resilient and scalable. Partner with leadership to drive key technology and design decisions, and to establish backend engineering best practices. Help foster a culture of high-quality code, great design, and a commitment to building for the long term. Who You Are You are a
systems thinker , who defaults to designing for resilience, scalability, and observability. You are pragmatic and product-aware, able to balance building elegant systems with the iterative needs of a fast-moving startup. You are passionate about
