Index 01
Make it rain.
Make agriculture less uncertain.
Sirius is researching a new generation of cloud seeding to strengthen water security, agriculture and climate resilience across Brazil.
Explore our mission01 · Vision
Water does not have to be predictable to be understood.
Crops, reservoirs and cities depend on how much water arrives and when. Sirius was founded to rigorously study the precipitation opportunities already present in the atmosphere.

02 · Science
Not creating clouds. Reading the moment when a cloud can do more.
Cloud seeding acts on clouds that already exist. The system begins long before any operation by observing humidity, temperature, wind and cloud structure.

From signal to outcome
Observe before acting. Measure before promising.
Four stages turn atmospheric conditions into a documented decision, including when the right decision is not to operate.
01
Observe
Combine radar, satellite and atmospheric data to identify potential windows.
02
Decide
Apply objective eligibility criteria and do not operate when they are not met.
03
Test
Structure authorized pilots with qualified partners and a predefined protocol.
04
Measure
Compare treated and untreated events, report uncertainty and publish inconclusive results.
03 · Technology
Method first. Scale second.
Autonomous infrastructure only makes sense when every decision can be explained. Capital follows evidence, not the other way around.

What Sirius proposes to build
From reading the sky to field infrastructure.
Sirius proposes an atmospheric technology platform connecting meteorological intelligence, radar and satellite data, autonomous drones and field validation. Deployment begins with modeling and authorized pilots, evolves into telemetry and integrated operations, and advances toward regional scale as the evidence supports it.
Technology roadmap
Each phase answers a critical question before increasing operational commitment.
Phase 01
0 to 12 months
Modeling
Build the initial decision system, define no-operation criteria and complete the regulatory roadmap.
Phase 02
12 to 24 months
Pilot
Structure the first field campaign with a licensed operator and a predefined protocol.
Phase 03
24+ months
Infrastructure
Evaluate proprietary dispersal capability and dedicated radar when the evidence supports expansion.
Indicative timelines, subject to scientific validation, applicable authorizations and the availability of qualified partners.
04 · Impact
One atmosphere. Three possible futures.
A water-intelligence infrastructure for water, energy and production. Sirius studies precipitation opportunities where supply systems, reservoirs, power generation and agricultural calendars share the same climate reality.
01
Agriculture and cooperatives
Pilots designed around the most critical windows in the agricultural calendar.
02
Energy and reservoirs
Basin studies where water availability and atmospheric conditions may justify a pilot.
03
Water resources
Institutional programs with governance, public criteria and independent measurement.
05 · Regions
Water changes the landscape. Method changes the horizon.
From the Cerrado to Brazil's semiarid region, each territory requires its own assessment, local governance and infrastructure proportional to risk. There is no universal operation for different climates.

06 · Validation
Evidence to move forward with confidence.
Every pilot is designed to produce actionable knowledge through clear criteria, consistent comparison and results that inform the next decision. Transparency is part of the technology.
01
Operate only when atmospheric conditions justify intervention.
02
Clearly distinguish published evidence from results produced by Sirius.
03
Define criteria, comparison methods and metrics before each pilot.
04
Turn every positive, negative or inconclusive result into learning.
05
Integrate science, safety and compliance from the design of each operation.
Legitimate questions. Clear answers.

07 · Partners
Evidence before fleet.
The angel round will fund the first modeling phase and preparation for a pilot operation with qualified partners.
