What Is Line.Build's Mission?

Line.Build's mission is clear and ambitious: to accelerate the transition to a greener and more energy-efficient economy. To achieve this, the founders recognized a significant barrier - the cost of technology adoption, especially in areas like heat pumps. Despite the availability of funds, such as utility rebates, the process of discovering and applying for them was far from straightforward. This realization fueled their determination to find a solution.

How Is Line.Build Transforming the Energy Efficiency Landscape?

Line.Build has emerged as a game-changer by addressing a crucial problem: the high cost of building decarbonization. Buildings are responsible for nearly 40% of US greenhouse gas emissions, making retrofitting for efficiency a vital step in mitigating climate change. However, the expenses associated with this transformation have been a roadblock for many.

The Problem: Fragmentation and Overhead

One major issue that Line.Build tackles is the hyper-fragmentation of available incentives and financing options. These resources are scattered across utilities, federal funds, grants, and green lending programs, making them difficult for contractors and consumers to access. Contractors, often responsible for helping consumers navigate this labyrinthine landscape, face increased overhead costs as they hire operations teams and consultants to meet demand. This situation not only impacts their bottom line but also affects their conversion rates, as consumers seek to maximize savings.

The Solution: A Unified Platform

Line.Build emerges as a beacon of hope in this complex scenario. It serves as a single source of truth for all available funding options. Contractors can access all incentives and financing options available to their customers simply by providing a few key details, such as the project address and scope. Line.Build then consolidates and simplifies requirements, making suggestions that help contractors maximize savings for their customers. This approach not only streamlines the process but also increases conversion rates for contractors, a win-win situation for all.

Streamlined Application Process

Once a customer is ready to proceed with a project, Line.Build offers the convenience of a common application for all eligible programs. Gone are the days of navigating multiple websites, printing documents, or mailing applications. The platform's user-friendly design is available in multiple languages and accessible on both web and mobile devices, ensuring ease of use and accessibility for all.

How Does Line.Build Empower Contractors?

Contractors play a pivotal role in the building decarbonization process. Line.Build empowers them with tools designed to make projects more affordable for their customers while simultaneously boosting conversion rates.

In a world where every dollar saved matters, these suggestions can make a significant difference. Maximized savings equate to maximized conversion rates, an outcome that benefits both contractors and their customers.
