Built by people who understand construction sites
SiteStock Sentinel was born from a simple observation: construction teams deserve inventory tools designed for the realities of jobsites — intermittent connectivity, rough conditions, and the pressure to keep projects on schedule and on budget.
We have spent years working alongside project managers, supervisors, and procurement leads to understand the pain of stockouts, overorders, theft, and slow manual reconciliation. The result is a mobile-first system that keeps project inventory accurate and proactively recommends the next actions to keep your projects supplied.
Our mission
To give every construction project team — from single-site subcontractors to enterprise general contractors — the material visibility and automated replenishment they need to eliminate waste, prevent loss, and deliver projects on time.
We believe that practical, reliable tools built for real field conditions can transform how construction teams manage materials. No hype, no feature-dense enterprise consoles that hide the core job in menus — just clear, actionable insights that help you scan, allocate, and approve faster.
What we stand for
Four principles guide every decision we make — from product design to customer support.
Practical
Grounded in real jobsite needs. We prioritize usefulness over novelty — every feature maps directly to how site teams actually work.
Reliable
Predictable, robust performance under site constraints. Offline-first, transparent sync status, and clear recovery paths you can trust.
Clear
Communication and visuals that remove ambiguity. Plain-language labels, concise status updates, and obvious next actions at every step.
Proactive
We anticipate needs and surface next-best actions — reorders, transfers, alerts — so your team acts before issues become critical.
How we build
Make the job obvious
Every screen answers 'What should I do next?' with a single clear primary action.
Show system state
Surface sync status, last update time, and confidence for offline-originated changes.
Favor short, actionable content
Concise labels and one-line helpers. Long explanations belong in documentation, not the UI.
Map to the site
UI choices reflect site roles, project context, and physical workflows — scan, allocate, approve.
Design for failure recovery
Explicit retries, undo where safe, and clear remediation steps for conflicts.
