About Tether

We exist to make buildings better.

Tether is a building performance company, born in Auckland, working across New Zealand, Australia, and the United Kingdom. We turn what buildings actually do into decisions, projects, and proof - and we stay until the outcome is verified.

Where we started

Born where bad buildings hurt the most.

“The first thing we ever measured was whether families were sleeping in cold, damp homes.”

Tether began in Auckland in 2017, inside a Housing New Zealand research programme into energy hardship in social housing. Before we ever priced a saving for a landlord, we measured what poor buildings do to the people who live in them.

That start set the standard for everything since: measure what matters, tell the truth about it, and make the fix provable. The company still runs on evidence, not estimates - and still holds the belief that better buildings are worth fighting for.

How we got here

Nine years, one direction.

Chapter 01 / 2017

Founded in Auckland.

Tether started as a building data company, born out of a Housing New Zealand research programme into energy hardship in social housing.

Chapter 02 / 2018-2022

From data to operating evidence.

Monitoring capability built across IEQ, occupancy, energy, water, gas, and BMS - always tied to a decision an operator or owner could act on.

Chapter 03 / 2023

Reframed around outcomes.

Save money, make money, certify, report, and comply became the master framework. Sustainability moved from headline to guardrail.

Chapter 04 / 2024

Three entities, three markets.

Tether B.V. and TetherHQ Limited stood up alongside Tether Limited, built to launch Tether into the UK and Europe and to establish the trading and reseller agreements that carry the platform there.

Chapter 05 / 2025

Endorsed product brands launch.

Better Buildings by Tether and MouldWatch by Tether launched as endorsed product brands. Ricoh and the Quidos Group / BEClimate channel deployments went live with Powered by Tether attribution.

Chapter 06 / 2026

Primed for scale.

MouldWatch lands and expands across 3,000 social homes. Better Buildings by Tether launches in September. Tether grows across all three markets.

What we believe

The thesis underneath the company.

  1. 01

    Performance increasingly affects access to capital, insurance, tenants, valuation, and compliance. Energy, carbon, indoor conditions, certification, and proof of improvement are moving from property-management detail to financial evidence. We would be wrong if building performance stays a low-priority facilities issue with no effect on capital.

  2. 02

    Customers do not want more disconnected dashboards, audits, reports, sensors, or marketplaces. They want outcomes they can act on: lower costs, stronger assets, certification achieved, reporting delivered, compliance kept, and proof ready when someone asks. We would be wrong if the market starts valuing standalone tools more than delivered results.

  3. 03

    Single-link platforms in this market get commoditised. Data alone, audits alone, reporting alone, finance matching alone are too easy to replace. The durable position is the operating layer that connects the full chain. We would be wrong if customers prefer fragmented specialists and continue to coordinate the chain themselves.

  4. 04

    Sustainability as a standalone sales message is weakening; the durable customer demand is commercial. We only support outcomes that improve environmental performance, but we sell what customers actually need. We would be wrong if customers consistently buy sustainability for its own sake without commercial reason.

  5. 05

    Building owners already trust banks, energy companies, insurers, assessors, property managers, and consultants. The fastest path to scale is becoming the intelligence and outcome layer behind those channels: one master brand, endorsed product brands, white-label deployments, and Powered by Tether attribution. We would be wrong if customers strongly prefer to buy direct.

Footprint and entities

One master brand. Three legal entities. Three markets.

Tether operates through Tether Limited, Tether B.V., and TetherHQ Limited. One platform sits underneath all three. Brand attribution stays consistent, even when partners own the customer-facing front door.

We hire for one thing above all: the patience to hold the chain together when others hand the customer back to the market.
