Laurenz Nascimento leads Sales Engineering at Radiant Security — an AI-powered Security Operations Center that helps security teams detect, investigate, and respond to threats faster. His small team supports a global sales organisation spread across the US, Brazil, Peru, Israel, and Portugal. Every demo that goes in front of a prospect runs through them.
For over two years, that meant running on Demostack. And for a while, it held. But Radiant Security's product moves fast — new alert types, new investigation workflows, frequent UI changes — and the demo environment couldn't keep pace. By the time a demo was built and distributed to the sales team, it was already six months behind what the product could actually do. Keeping it current meant rebuilding from scratch each time, not updating in place. A single significant update could consume two days of preparation time — time spent rebuilding rather than selling. The result was a growing collection of smaller, piecemeal demos patched together to cover the gaps — none of them complete, none of them fully interactive, none of them reflecting the current product.
The cost was invisible but constant: every sales call was a demonstration of yesterday's capabilities.
The structural problem ran deeper than maintenance speed, though. Radiant Security's most compelling demo content doesn't live in one place. The strongest alert examples, the most persuasive investigation flows, the scenarios that land hardest with specific buyer profiles — they're distributed across different customer tenants, staging environments, and partner instances. With Demostack, those examples stayed where they lived. There was no way to pull them together into a single, coherent story.
Interesting examples live in different environments. The ability to build a coherent story for a demo is what made us switch to Demoboost.
Sharing sandbox environments with prospects compounded the problem further. Radiant Security's product isn't quick to evaluate — a full deployment takes weeks, time most prospects won't commit to early in the sales process. Without a shareable sandbox that reflects the real product, every early-stage evaluation was an uphill conversation.
Where Demostack required working within the boundaries of a single cloned environment, Demoboost gave Laurenz two things that changed how he builds and maintains demos entirely: modular updates and multi-environment composition.
Building by composition meant Laurenz could now pull screens from production, staging, or a specific tenant — an alert captured here, an investigation flow from there — and wire them together into a single navigable demo that tells exactly the right story, regardless of where each piece originally came from. The best content from across the entire product landscape, assembled into one coherent experience.
The second shift was modular maintenance. When a UI change ships — and at a fast-moving cybersecurity startup, that is a near-constant reality — Laurenz updates the affected screens and leaves the rest intact. He no longer rebuilds. He patches, confirms, and moves on. Updates that previously consumed days — or weeks for a large sandbox — now take hours. Across a typical update cycle, that's 10 to 20 hours returned to the team.
It gave me the ability to update smaller parts of a current demo without starting from scratch, which was necessary to keep up with product updates. As an SE, I want to always show the newer capabilities.
The flagship sandbox grew to over 500 screens, drawing from multiple environments and covering a full range of alert types, evidence flows, and investigation paths. A prospect can click through a complete, realistic investigation — from triage to escalation — without Radiant Security provisioning a live environment, and without the SE team needing to be in the room.
Within two weeks of starting, all prospect-facing demos at Radiant Security were running through Demoboost.
The sandbox unlocked two sales motions that were previously difficult to support.
The first is prospect evaluation without deployment. For buyers who cannot or will not commit to a full implementation just to assess the product, the sandbox gives them a realistic, fully explorable experience — the alerts, the evidence, the investigation flow — with no infrastructure on their end. It answers the question every security SE dreads: can we just see how it actually works before we decide anything?
The second is partner enablement. Channel partners can now demo Radiant Security's product independently, in an environment that looks and behaves like the real product, without needing a dedicated SE on every call. For a small presales team supporting a global sales organisation, that is not a convenience — it is how the team scales.
The way account executives adopted the sandbox tells its own story. Laurenz shared a direct link. They bookmarked it. No login, no setup, no coordination required — just a click, and they were in the demo. For a sales team that had grown used to unreliable environments and last-minute prep calls, that reliability changed how they sell. Demos that previously required the SE team to be present now happen independently, across time zones, without them.
Updates that used to take days or even weeks can now be done in a matter of hours, which greatly improves the SE experience and speeds up the time to demo exciting capabilities. As a startup, the product updates so quickly that this is a must-have.
Looking ahead, Laurenz is tracking sandbox engagement data — which screens prospects spend the most time on, where they navigate next, and how those signals map to deal outcomes — with the goal of shortening the sales cycle at the business level. The demo is no longer something the team needs to be present for. It is something that works while they are building the next version.
