Guilder is the AI platform that turns weeks of research, phone calls, and rebate paperwork into a single guided experience. Share your address, utility bill, and a photo of your equipment — we handle the rest.
The average motivated homeowner spends 40+ hours researching electrification upgrades and still ends up stuck. Hundreds of overlapping programs. Dozens of contractor quotes. No guidance on sequencing. Most never start. The ones who do, overpay — and leave federal, state, and utility money on the table.
Drop an address below for a live preview — roof geometry, sample upgrades, projected savings. About ten seconds, no signup.
We built Guilder so you'd never have to fill out a 40-field form or schedule a $300 energy audit. Give us three pieces of information — the rest is automatic.
We pull satellite imagery, county assessor records, local climate data, and solar irradiance for your exact parcel. No questionnaire. No site visit.
Upload a PDF or snap a photo. We extract 12 months of kWh and therm data to build a baseline of how your home actually behaves through every season.
Snap a photo of your water heater, furnace, AC, or the label on the back of the washer — plus any paperwork that came with it. We read the model and date plate, match it in our database, and know exactly what to replace it with.
Everything a homeowner needs to electrify — diagnosis, incentives, sequencing, contractors — unified into a single guided experience. No site visits. No phone calls. No spreadsheets.
Most "free home assessments" are glorified ZIP-code lookups — averages pulled from a table. Guilder does something different: every recommendation comes out of an engineering-grade simulation of your house, not a generic one.
Distinct data points feed every analysis — satellite-derived roof geometry, parcel records, 12 months of utility data, solar irradiance, equipment specs, climate norms, and dozens of values we compute from those.
Site visits required. The competing "free audits" need scheduling, a home visit, and a sales pitch. Ours runs in under a minute from your couch.
Of your actual usage data informs every number — not a generic average for your zip code. Your winter peak, your summer baseline, your mid-day load.
Every competitor addresses one piece of the process. Guilder unifies diagnosis, incentives, sequencing, and contractor execution into a single platform that actually gets projects across the finish line.
Synthesizes satellite imagery, county assessor records, NREL solar irradiance, appliance specs from your photo, and actual utility usage into a precise physical and energy model — without anyone visiting your house.
Continuously scans 400+ federal, state, utility, and municipal programs. Identifies every program you qualify for and pre-fills applications automatically — including ones most homeowners never hear of.
Engineering-grade simulation — real thermodynamics, not averages — ranks improvements by ROI for your specific home and climate. The right things, in the right order.
Pre-vetted HPIN, BPI, and NABCEP-certified local pros bid on a project already fully scoped. Performance-ranked by completion rate, price accuracy, and homeowner satisfaction. Underperformers are removed.
Every home is different, but the physics aren't. These are the seven electrification and efficiency upgrades Guilder models, ranked by average impact across typical New England single-family homes. Your roadmap will vary — but this is the hierarchy.
Solar marketplaces only help if you already know you want solar. Contractor networks give you a name and a number. Government sites list programs and leave you to decode them. Guilder is the only platform that connects diagnosis, incentives, sequencing, and execution into a single path.
Everything you need, nothing you don't. The interface surfaces decisions — not data. You see the number that matters, the action to take, and the tradeoff behind each choice. That's it.
Residential buildings produce 13–15% of US greenhouse emissions. Unlike power plants, that footprint can't be fixed centrally — it has to be fixed house by house. The technology exists. The money is on the table. We're the missing piece that turns desire into action.
Start with your home →Most lead platforms sell you a name and a phone number. Guilder sends you a homeowner with a fully scoped project, stacked incentives, and an optimized upgrade plan. You show up to close, not to educate.
We're starting in Fairfield County, CT — where high-value housing stock, proactive state incentives, and a mature certified-contractor base let us validate the model fast, then scale.
