Incentives and financing for energy efficiency upgrades
Line.Build is software for contractors to seamlessly find and apply for financing and rebates for energy efficiency upgrades. With buildings accounting for almost 40% of US GHG emissions, retrofitting for efficiency is essential to reduce emissions and load on the grid, but expensive. Over $80B of rebates, incentives and financing is available but hyper-fragmented across utilities, federal funds, grants, and green lending programs. Line consolidates disparate sources of funds and simplifies finding and applying for incentives and financing. Line is designed to be user-friendly, available in multiple languages, and accessible on both web and mobile devices. Additionally, it provides an API that seamlessly integrates with existing quoting tools, enhancing efficiency and convenience.
As reported in public records reported — not modeled.
Solid bars are reported offering amounts reported; hatched bars are the modeled post-money valuation est. — both on one shared scale so you can read raise-vs-worth at each round directly. Use the toggles to overlay data labels and the niche-peer / market average value lines.
No round amounts on record to chart.
No staged rounds to sequence.
Round size and date are reported; the stage label is inferred from round size. Valuation is modeled from stage benchmarks. Directional, not a quoted figure.
Not enough modeled valuation points to chart a trajectory.
Benchmarked against 69 companies in Energy. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.
Raised more than 54% of sector peers (real $). Modeled value above 54% of peers (estimate).
Stage is inferred from round size est., not reported on the filing — a round's dollar size maps to a bucket: Pre-Seed <$1.0M · Seed $1.0M–$4.0M · Series A $4.0M–$15M · Series B $15M–$40M · Series C $40M–$100M · Series D+ $100M–$400M · Growth/Late >$400M.
