◈ HYDRAA PRODUCT OF ULLUR LLC

BUILT FOR YOUR HOME. READY TO ACT.

Life happens.
Water damage
shouldn’t.

Meet HYDRA. The patent-pending Fully Autonomous, Multi-Sensor Plumbing Protection System. It acts autonomously in seconds and reports to the app in real time.

Working prototype. Engineering and certification come before home installations.

01 / PROTECTION THAT THINKS AHEAD

While you live your life,
HYDRA watches the water.

A cold night. A hidden leak. HYDRA is designed to respond before you reach for your phone. Explore the logic below.

TRY A SCENARIO

Water on. Worries down.

In normal conditions, the main stays open and the freeze trickle stays off.

  2. 02 Act autonomously in seconds
  3. 03 Report to the app in real time

HYDRA APP · ILLUSTRATIVE REPORTAll clear

Main open. Freeze trickle off.

A / CONTAIN

A leak stays local.

The affected zone closes first. The rest of the house keeps water. Leak response always takes priority, even during a freeze or manual override.

B / KEEP MOVING

Cold calls for action.

At 32°F or below, an automatic metered trickle keeps the line moving. Temperature never closes the main. Pressure relief works independently of power.

C / LOOK AHEAD

A nightly check-in.

A scheduled 3:00 AM pressure test looks for pinpoint leaks and running toilets. Pressure is monitored and alerted on; software does not control its release.

02 / EVERY GALLON MATTERS

Big protection.
A smaller trickle.

An open faucet is a guess. HYDRA is designed to meter a small, automatic freeze trickle.

WATER-SAVINGS DESIGN TARGET
Compared with the 3 gal/hr open-faucet baseline.

A target, not a measured result. HYDRA’s 0.5 gal/hr delivered discharge flow has not yet been measured. Savings shown are illustrative arithmetic, not verified field savings.

Same cold spell.
Different water story.

*Single-faucet comparison; home illustration assumes one faucet. Rates: 3 gal/hr baseline versus 0.5 gal/hr design target. A 72-hour freeze is an assumption.

03 / BUILT. TESTED. STILL PUSHING.

Four pipes.
One very cold night.

Four lines in the same freeze chamber. Same temperature. Same duration. Two protected by HYDRA. Two unprotected controls.

CONTROLLED COLD TEST−39.5°F

Temperature driven down and held until the probe reached its measurement limit.

Founder-reported outdoor rig test, as documented in the Hydra briefing. Control bursts were physical observations; the control lines had no sensors. This is prototype evidence, not independent certification or a guarantee of performance in every home.

What happened when a leak was triggered mid-freeze?

With the chamber between 9°F and 27°F, water was sprayed onto one protected line’s leak sensor. That line entered LEAK, its valve stayed closed for 38 minutes, and its trickle stopped. The other protected line kept trickling normally. Source: Hydra briefing.

04 / A DIFFERENT APPROACH

More layers.
One connected response.

Compare the jobs each approach is designed to do. HYDRA brings zone isolation, freeze response, pressure relief and scheduled testing together.

05 / MEET THE INVENTOR

Built through hands-on work.
For the places we call home.

Meet Jeremiah Christian Stark, the person building HYDRA. Based in Little Rock, he does maintenance work at many locations across Arkansas.

He built the prototype by hand, self-funded, alongside his full-time job. The work comes from hands-on experience with plumbing and the problems that arise when water goes where it shouldn’t.

HYDRA is still in development. The four-pipe test is an important step; the next is turning that working rig into a finished, engineered and certified product before home installations can begin.

HYDRA is patent pending and has been accepted into ARiSE, the AEDC-backed program run through Conductor.

THE NEXT CHAPTER

Real progress.
A clear path forward.

Seeking $200,000–$600,000 in non-dilutive funding to turn the test rig into a manufacturable product and complete certification. No equity is being offered.

  1. 01 / PROTOTYPE

    Built & tested

    Founder-built rig and controlled cold-test evidence.

  2. 02 / ENGINEERING

    Product development

    Finalize a manufacturable design.

  3. 03 / CERTIFICATION

    Clear the gate

    Potable-water certification, plumbing compliance and electrical listing before installation.

  4. 04 / AFTER CERTIFICATION

    Pilots & first sales

    Build real-world home performance data.

Planned model: hardware plus $50/month for the app, 24/7 monitoring and free service visits for installed equipment failures. Hardware pricing and availability are not announced. No installations are being booked here.

QUESTIONS. IDEAS. CONVERSATIONS.

Let’s talk about HYDRA.

Curious about the prototype, the testing or what comes next? Jeremiah welcomes a conversation.

HYDRA is in development. Home installations will follow final engineering and certification.
