Mission-critical

Sift is building the observability layer for hardware, turning fragmented sensor data into real-time, AI-ready insights for mission-critical systems.

Every mission to space eventually has to answer the same question: will this hardware still work after it leaves Earth?

Software that controls hardware is only as reliable as the conditions it was tested against.

Sim Wang went to Rensselaer to become a rocket scientist. Twenty years of simulation, digital twins, and autonomous driving later, he joined Sift to work on the problem that ran underneath all of it: engineering data.

Your agent can now talk directly to Sift, alongside your code, notebooks, and local data. Ingest, explore, and analyze hardware telemetry without leaving the workflow you already use.

Plantd turns the world's fastest-growing grasses into carbon-capturing structural panels. To support their unique manufacturing process, their engineers use Sift to monitor every machine in the factory, tie anomalies to specific panel batches, and catch problems before they cause downtime.

A useful telemetry record follows the way an investigation unfolds: from the live value, through the history around it, into the work your team shares in its Sift tenant after the test.

Curate a set of nominal test runs, align them on the events that matter, and automate review against that baseline as your campaign grows with Sift Families. See how Sift Families can accelerate your test cadence.

Longshot Space is building a kinetic launch system where success or failure hides in a fraction of a second. See how they use Sift for data fidelity and granularity because the details that decide success and failure can't get averaged away.

Sift, the data infrastructure platform for physical AI, has achieved FedRAMP High certification in partnership with Knox Systems, the largest federal managed cloud provider. The authorization gives federal agencies access to a purpose-built platform for hardware sensor data — with automated anomaly detection, real-time review, and long-term retention across programs — clearing the way for Sift to expand into national security and defense work.

The most impactful practice in modern software development is now available for hardware. Sift enables continuous validation for complex machines. This is how CI/CD principles and Sift’s Rules give engineers continuous releases, greater certainty, and less risks and costs.

Propulsion development lives or dies by test cadence. When the data pipeline is fragmented , the iteration loop slows. The Exploration Company (TEC) tests with Sift, accelerating two of Europe’s most ambitious propulsion programs: the Mistral green hypergolic thruster and the Huracan electric-pump-fed cryogenic rocket engine.

Sift is expanding to two cities with new senior leaders across engineering, sales, and design to bring modern data infrastructure to rockets, robots, and autonomous machines.

A hardware team's most valuable asset is the accumulated judgment of its engineers. The instinct to protect it by freezing the design is ironically what destroys it. Here's how the best teams manage risk through change and turn attrition risk into engineering acceleration.

When your mission is on the line, every second counts. See how we made search 20x faster: from regex to real time.

You'll outgrow your Grafana backend before you outgrow Grafana. Here's how to keep the dashboards you love without the infrastructure pain.
