A rebate is a peculiar kind of money. It belongs to you, in principle. It may even be written into law, blessed by a utility and promoted on a cheerful government website. Yet at the moment you need it most, when a contractor is sitting across the kitchen table with a five-figure quote, the money is usually elsewhere. It may arrive in weeks. It may arrive in months. First come the forms.
Samir Pendse has built Coral around that interval between promise and payment. The New York company he co-founded in 2023 turns verified incentives for heat pumps and other efficient building upgrades into immediate discounts. Coral advances the rebate, the contractor subtracts it from the bill, and the homeowner gets to consider the price that matters now. Coral then deals with the administrative afterlife: eligibility, evidence, submission and reimbursement.
There is no new compressor hiding in this story, no gleaming battery chemistry and no heroic redesign of the American house. The invention is temporal. Pendse looked at a benefit that arrived late and asked what would happen if it arrived on time.
The recurring problem
Money that exists, but cannot quite be reached
Pendse arrived in climate through finance. Early in his career he worked in new product development at Accion US Network, the microfinance nonprofit serving small businesses that conventional lenders often miss. He later joined Boston Consulting Group, where his work included helping build small-business lending products. At Snowe, the home-goods startup, he led strategy and business operations.
Read backward, the career has an unusually tidy plot. Each stop concerned useful capital, operational friction and the smaller business or household stranded on the wrong side of both. The names of the borrowers changed. The old difficulty did not. Money could be available in theory while remaining useless in practice.
Pendse studied economics and political science at Northwestern, then earned an MBA from Wharton, where he co-led the Politics and Public Policy Club. Coral sits neatly where those interests overlap. A rebate is public policy with a user interface. If the interface is a pile of forms and a six-month wait, the policy may be generous and still fail at the point of decision.
“Most homeowners are not trying to get a heat pump. They just need heat in their home.”Samir Pendse
That sentence supplies the company’s compass. A person with a dead furnace in January is not enjoying a leisurely seminar on building decarbonization. The house is cold. The decision is urgent. The alternatives are compared by price, reliability and how quickly someone can restore comfort. A future rebate is weak medicine for a present invoice.
The fieldwork
Hundreds of contractors, one stubborn answer
Before Coral found its model, Pendse and co-founder Nizar Dhamani went looking for the actual constraint. They spoke with hundreds of contractors, joined them in the field and listened to how efficient systems were sold. The refrain was not that heat pumps lacked advocates. It was that the price was hard to carry. Even when long-term energy savings were persuasive, a homeowner still had to survive the upfront number.
That changed the assignment. Software could help identify a rebate, but information alone would not make the rebate immediate. Contractors also had a cash-flow problem. Smaller installers could not casually wait months for reimbursement, nor could they afford endless staff hours correcting submissions. If a promised incentive was denied, the installer could be caught between an angry customer and a utility rulebook.
From quote to reimbursement
Coral therefore became part software company, part compliance desk and part financial bridge. Its platform checks incentives, gathers documents and files the claim. Its capital turns the expected payment into a discount today. What looks simple on the customer’s quote rests on the unlovely work of knowing which program applies, which equipment qualifies and which proof will satisfy which administrator.
Pendse seems to enjoy the unlovely work. On podcasts, he speaks less like a prophet of domestic electrification than an operator irritated by a broken process. He is happy to describe the forms, the reimbursement lag and the dealer fees that make a theoretically sensible purchase harder than it should be. His humor is dry; his preferred drama is a number getting smaller.
The sales argument
Comfort first. Carbon comes along for the ride.
Pendse is candid about not leading every conversation with climate. Different people enter the transaction with different motives. A contractor wants to close a good job without becoming a rebate scholar. A homeowner wants dependable heating and a manageable payment. An investor wants a durable market and defensible infrastructure. The environmental benefit is real, but insisting that every customer begin with it would confuse moral satisfaction with product strategy.
This is persuasion by subtraction. Remove the unfamiliar acronyms. Remove the uncertainty about whether a check will come. Remove the extra amount a household must finance while waiting. What remains is a piece of equipment, a comfortable home and a price that can be compared with the familiar alternative. Pendse does not treat this simplification as cosmetic. In a rushed replacement decision, clarity is part of affordability. Confusion has a price, even when it never appears as a line item.
His message is plainer: make the efficient option cheaper and easier. Coral says contractors using its platform report sales-conversion improvements of 25 to 30 percent. The number matters because it converts policy intent into installed equipment. A rebate that produces no purchase is a brochure. A rebate that changes the quote can change the house.
This is also where Pendse’s empathy becomes commercial. He describes climate founders as needing to behave like chameleons, not because the underlying mission changes, but because the useful language does. Talk to the person in front of you. Respect what they are trying to solve. A homeowner should not have to adopt a founder’s vocabulary before receiving a better deal.
The same pragmatism shaped the fundraising. Pendse has said Coral pitched fintech investors as well as climate investors. That is logical: the company is underwriting timing risk, moving capital and building a compliance system. The decarbonization benefit does not make the financial mechanics less exacting. If anything, the maze of utility and government programs makes them more so.
The expansion
A $7.5 million wager on useful bureaucracy
In March 2026, Coral announced a $7.5 million seed round led by ResilienceVC. The investor group included Twelve Below, Floating Point, Accion Ventures, Blackhorn Ventures, Remarkable Ventures and New Climate Ventures, with a strategic investment from Watsco Ventures. The latter is attached to North America’s largest HVAC distributor, a useful ally when your product must travel through the trade rather than around it.
By then, Coral said it powered more than 100 installers across the Northeast and had helped sell almost 4,000 heat pumps. Its network included work with Watsco and Mitsubishi Electric Trane HVAC, while Accion later noted integrations spanning Watsco, Mitsubishi and ServiceTitan. The new money was earmarked for national expansion, more kinds of upgrades, including water heaters and batteries, and financing products that can reduce the remaining cost after incentives.
The partnership map also reveals Pendse’s instinct for distribution. Coral does not need to persuade every homeowner from a standing start if its tools already sit beside the people, equipment and software involved in the sale. The installer brings trust. The distributor moves the hardware. The manufacturer knows the eligible models. The workflow platform already holds the job. Coral’s opportunity is to connect the incentive without asking the rest of the industry to reinvent itself.
Accion taught Pendse about serving borrowers overlooked by familiar systems. Coral applies the same instinct to homeowners and small contractors navigating incentives that technically exist but are practically hard to use.
Expansion will make the original problem larger before it makes it easier. Every state, utility and program brings its own conditions. Equipment lists change. Forms disagree. A company that promises certainty must absorb this complexity without leaking it back to the contractor. The paperwork is not incidental to Coral’s product. It is the terrain.
That is why Pendse’s story is less about leaving finance for climate than carrying one question into a new room. Who can use the money, and when? Microfinance posed it for small enterprises. Lending products posed it for bank customers. Heat-pump rebates pose it for families staring at an expensive replacement on the coldest day of the year.
Coral’s answer is modest enough to sound obvious: give them the benefit when the decision is made. Obvious ideas are often merely ideas whose paperwork has been edited out.
