Building intelligence, from the pour onward

Intelligence for a building's entire life.

A 50-year operations platform that starts at the concrete pour -- not a retrofit bolted on after the ribbon-cutting.

Building intelligence from design through occupancy and fifty years of operation.

The problem is structural, not technical

A 50-year lifecycle begins blind.

Facility managers inherit buildings with no decision history. No embedded sensors -- operational intelligence starts from zero the day a building opens. Construction and operations run as two disconnected systems.

  • Buildings consume 40% of global energy -- the largest single sector
  • ~30% of construction data is lost at commissioning and handover

Data ownership is the actual moat

Precision agriculture is the precedent: farmers adopted yield-tracking platforms under pressure, and their soil profiles and productivity data became the vendor's property -- a decision made at the point of highest need, before anyone read the terms. A decade later they're in state legislatures fighting to get that data back.

AEC is at the same decision point today. Current terms of service from major platform providers claim aggregate ownership over customer content, or the right to use it for internal analytics and disclose derived insights to third parties. The building owner who paid for the infrastructure doesn't own their own operational history once they adopt one of these platforms.

Siltana's business doesn't depend on monetizing the building's operational history.

EctropyThe construction intelligence platform that binds each decision to its place, its cost, and its people.

Built on Ectropy's open core, the platform is designed so a facility manager can audit, self-host, and verify every decision in the archive.

Nobody else is building the bridge

Building management software and construction software are sold by different vendors, to different buyers, on different timelines -- so the handoff between them is where a building's intelligence gets lost.

Retrofitting sensors into a building that's already occupied is slower, more disruptive, and structurally worse than embedding them at the pour -- which is the case for installing at construction instead of after the fact, independent of any specific price comparison.

OhjausOpen-standard sensor infrastructure for embedded applications.

Ohjaus-supplied sensor hardware, designed to be embedded during construction -- not retrofit.

Sensors, fleet, and work orders, all spatially indexed to the same BIM

Embedded at the pour, not retrofit after occupancy.

50+ year structural health monitoring, centimeter-accurate UWB positioning for robot fleets, and environmental sensing intended to install at the pour.

Multi-vendor fleet management designed to unify cleaning, security, delivery, and inspection robots under one registry, navigating from BIM-derived maps instead of a site-specific integration for each vendor.

Voxel-indexed work orders, full asset lifecycle tracking, energy analytics from BMS integration, and emergency response with first-responder pre-plans, designed to be spatially indexed back to the original BIM.

Who Siltana is for

Building owner
A complete decision record designed to belong to you, not the platform that installed it -- self-hostable and auditable, built on Ectropy's open core.
Facility manager
Operational intelligence that starts at the pour instead of from zero on day one -- a 50-year record, not a blind handoff.

Where Siltana is today

Siltana is pre-product: the platform above is designed, not yet shipped. The building's complete decision record is designed to belong to the owner, not the platform that installed it.
