Gradient’s heat pumps get new smarts to enable old-building retrofits
New York City and others like it are filled with old buildings that are for the most part fine, except they’re not all that comfortable to live in. Built in an era when massive boilers were cutting-edge technology, the buildings are usually too hot or too cold, but seldom just right.
There are companies trying to rectify that using clever horseshoe-shaped heat pumps. Superficially, they’re similar to window air conditioners, except they don’t block the view and they can heat as well as cool.
Gradient makes one of those heat pumps, but now it’s adding a twist: In multifamily buildings, it can link every one of its window units together. The startup shared with TechCrunch exclusive details about the new Nexus software and service.
“Multifamily buildings are an ignored sector,” Vince Romanin, chief technology officer at Gradient, told TechCrunch. “It’s a place where we can do better for the user.”
The startup is mostly targeting old buildings that need HVAC upgrades. Gradient has worked with the New York City Housing Authority to install its heat pumps in public housing, and it ran a pilot in Tracy, California, in a newer two-story affordable-housing complex. It’s also talking with colleges and universities, many of which have dorms that weren’t built with hot autumn weather in mind.
Old buildings often have one electric meter, which can tempt residents into overusing their heating or air conditioning. Nexus gives some control back to building managers. They can set guardrails to prevent people from overusing the heat or AC — either intentionally or otherwise — while still allowing them to be comfortable. In one instance, a building manager set the heating limit at 78˚ F, and the next day energy consumption dropped by a quarter.
Romanin said Gradient’s heat pumps are the “lowest-cost option” for old buildings with boilers that are reaching end of life, a common occurrence in New York City. As a bonus, units that previously only had a steam radiator now get air conditioning, future proofing the units against worsening heat waves.

By installing a window unit rather than a minisplit, retrofits can happen within hours. They also don’t require electrical upgrades, Romanin said. In buildings with old electrical wiring that can’t support a full 12 amp load on a single outlet, Nexus can reduce the draw, said Mansi Shah, senior vice president of product and software at Gradient.
That strategy can extend beyond the building too. When the grid is overwhelmed by demand, which can happen on hot summer days, Gradient is working on a way to dial back its heat pumps while still maintaining occupant comfort. By using information about the building along with feedback from sensors in the heat pumps, the company hopes to predict which units can reduce their air conditioning demand, like those on the shady side of a building. That sort of demand response can help the grid serve more heat pumps without requiring costly upgrades.
“There’s a lot of people who said when we electrify everything, the grid won’t handle it,” Romanin said. “I think that it is very possible to electrify everything and make the grid better, make the grid’s job easier, and make electrons cheaper.”

Peak XV says internal disagreement led to partner exits as it doubles down on AI
Peak XV Partners, a leading venture capital firm in India and Southeast Asia, has seen a fresh round of senior departures. These follow other leadership exits over the past year as it pushes ahead with plans to deepen its focus on AI investing and expand its footprint in the U.S., while keeping India as its largest market.
The latest departures stem from an internal disagreement with senior partner Ashish Agrawal (pictured above, left) that led to a mutual decision to part ways, Managing Director Shailendra Singh told TechCrunch. He added that two other partners, Ishaan Mittal (pictured above, right) and Tejeshwi Sharma (pictured above, center), chose to leave alongside him.
Singh said Peak XV did not want to go into the specifics of the disagreement and was focused on moving forward. “Just out of privacy, and out of, like, trying to be classy about it,” he said. Singh added that such departures were not uncommon at large, multi-stage venture firms and that Peak XV wanted to move on quickly after several years of working together.
All board seats held by the departing partners would be transitioned “imminently,” Singh said, noting that the firm already had overlapping representation across several portfolio companies. He said Peak XV was not concerned about continuity, noting that multiple general partners and operating partners were already involved across many of those boards.
The departures mark the exit of long-tenured investors from the firm. Agrawal had been with Peak XV for more than 13 years, while Mittal spent over nine years at the firm and Sharma more than seven years, per their LinkedIn profiles.
Agrawal wrote in a LinkedIn post that he had decided to “take the entrepreneurial plunge” and was teaming up with Mittal and Sharma to start a new venture capital firm. He described the move as an opportunity to build a new institution with longtime partners and thanked Peak XV’s leadership for what he called a “truly wonderful partnership.”
During his time at Peak XV, Agrawal led investments across fintech, consumer, and software, including Groww, one of the firm’s most prominent IPO exits in 2025. He also backed multiple early- and growth-stage companies alongside Mittal and Sharma, contributing to Peak XV’s broader portfolio build-out over the past decade.
Agrawal, Mittal, and Sharma did not respond to messages for comments.
Peak XV has also moved to strengthen its senior leadership from within. The firm on Tuesday promoted Abhishek Mohan to general partner, expanding its investment leadership bench, while Saipriya Sarangan was elevated to chief operating officer, taking charge of firm-wide operations.
The leadership changes come amid a standout year for Peak XV’s portfolio exits. Five of its companies — Groww, Pine Labs, Meesho, Wakefit, and Capillary Technologies — went public in November and December 2025, generating roughly ₹300 billion (around $3.33 billion) in unrealized, mark-to-market gains for the firm, in addition to about ₹28 billion (about $310.61 million) in realized gains from share sales during the IPOs.
In addition to the latest departures, Peak XV has seen a broader churn in its senior ranks over the past 12 months. Last year, long-time investment leaders Harshjit Sethi and Shailesh Lakhani exited the India team, while Abheek Anand and Pieter Kemps departed from the firm’s Southeast Asia operations. The firm has also seen leadership changes across its marketing, policy, and operations teams in recent months.
Singh dismissed a view circulating in the market that many of the partners who drove Peak XV’s largest exits were no longer at the firm, calling the narrative “not statistically true.” He said several of the firm’s most significant outcomes had been led by long-tenured partners who remained at Peak XV, and argued that the firm’s exit track record did not hinge on any single individual.
Peak XV currently has seven general partners, along with multiple partners and principals, according to Singh.
The VC firm, which split from Sequoia Capital in 2023 and currently manages over $10 billion in capital across 16 funds, has made about 80 investments linked to AI, Singh said, highlighting its push to deepen its focus on AI funding. It is also preparing to open a U.S. office within the next 90 days as it expands its global footprint, per Singh, while continuing to view India as its largest and most important market.
Singh stated the firm believed AI would reshape venture investing more profoundly than previous technology shifts, arguing that successful AI investing required investors with deep technical understanding rather than “generalist” experience. He added that Peak XV was looking to add more AI-native talent, including researchers and engineers with backgrounds in machine learning and large-scale model development.
The firm has invested in more than 400 companies, and its portfolio has seen over 35 initial public offerings and several M&As to date.

PayPal hires HP’s Enrique Lores as its new CEO
PayPal said on Tuesday it is hiring HP’s Enrique Lores as its CEO and president, replacing current chief executive Alex Chriss. Lores, who has been the chair of PayPal’s board since July 2024, will also take up the role of president.
PayPal said the appointment was made because the company’s pace of change and execution was “not in line with the Board’s expectations” given broader market trends.
Chriss joined PayPal in September 2023 from Intuit, succeeding Dan Schulman. PayPal’s CFO and COO, Jamie Miller, will take over as interim CEO until Lores joins the company.
The appointment comes as PayPal on Tuesday reported lower than expected revenue and profit in the fourth quarter, as consumer spending dipped amid a broader cost of living crisis and a softening labor market. The company also forecast a dip in its full-year profit, which surprised investors, as Wall Street had broadly expected the company to forecast growth instead.
PayPal’s shares were down about 17.9% in premarket trading on Tuesday.
Lores, who served as president and CEO of HP for over six years, said that apart from product innovation, PayPal will hold itself accountable for delivering quarterly accounts.
“The payments industry is changing faster than ever, driven by new technologies, evolving regulations, an increasingly competitive landscape, and the rapid acceleration of AI that is reshaping commerce daily. PayPal sits at the center of this change, and I look forward to leading the team to accelerate the delivery of new innovations and to shape the future of digital payments and commerce,” Lores said in a statement.

Fitbit founders launch AI platform to help families monitor their health
Fitbit founders James Park and Eric Friedman have announced the launch of a new AI startup called Luffu that aims to help families proactively monitor their health. The duo are developing an “intelligent family care system” that will start with an app experience and then expand into hardware devices.
Two years after their exit from Google, Park and Friedman are betting on AI to help lighten the mental burden of caregiving. According to a recent report, 63 million, or nearly 1 in 4, U.S. adults are family caregivers, up 45% from 10 years ago.
Luffu uses AI in the background to gather and organize family information, learn day-to-day patterns, and flag notable changes so families can stay aligned and address potential well-being issues.
“At Fitbit, we focused on personal health—but after Fitbit, health for me became bigger than just thinking about myself,” Park said in a press release. “I was caring for my parents from across the country, trying to piece together my mom’s health care across various portals and providers, with a language barrier that made it hard to get complete, timely context from her about doctor visits. I didn’t want to constantly check in, and she didn’t want to feel monitored. Luffu is the product we wished existed—to stay on top of our family’s health, know what changed and when to step in—without hovering.”

The pair note that today’s consumer health market is filled with tools for individuals, but that real life health is shared across partners, kids, parents, pets, and caregivers. Family information is scattered across devices, portals, calendars, attachments, spreadsheets, and paper documents.
With Luffu, people will be able to track the whole family’s details, including health stats, diet, medications, symptoms, lab tests, doctor visits, and more. Users can log health information using voice, text, or photos. Luffu proactively watches for changes, and surfaces insights and alerts, such as unusual vitals or changes in sleep.
The pair told Axios that people can ask questions using plain language to ask about their family’s health, such as “Is Dad’s new meal plan affecting his blood pressure?” or “Did someone give the dog his medication?”

“We designed Luffu to capture the details as life happens, keep family members updated and surface what matters at the right time—so caregiving feels more coordinated and less chaotic,” Friedman said in the press release.
People who are interested in Luffu can join the waitlist for the limited public beta.
