Humidity sucks. Transaera has a new way to deal with it
“It’s not the heat that’s killing you, it’s the humidity,” my father said somewhere.
His kids might roll their eyes, especially in the event that they’ve spent any time within the desert Southwest in the course of the summer, but their dad is a minimum of partly right: high humidity not only makes people less convenientalso puts a strain on air-con units. Half of the energy used to power a typical air conditioner is used moisture removal from the air.
For firms like Amazon, Walmart, UPS and FedEx that operate massive warehouses, air-con is becoming a growing problem. Temperatures inside warehouses can rise to uncomfortable levels, potentially dangerously hot.
A startup is working on a solution to the moisture problem. Transaera is developing a unique air-con solution for homes and apartments that uses a special material to remove moisture before cooling the air. Since greater than 2 billion people in hot, humid regions still lack air-con, the corporate hopes it might help meet that demand while reducing the quantity of energy required.
But first, while it refines the buyer product, it’s rolling out larger units to industrial buildings like warehouses. On Tuesday, it installed the primary one on a customer’s roof, the corporate told TechCrunch exclusively. This dedicated outside air system (DOAS) dehumidifies fresh air coming into the constructing, reducing the workload on the air conditioner.
“DOAS is a small piece of the market, but it’s a growing segment,” co-founder and CEO Sorin Grama told TechCrunch. “It’s just an easier entry point.”
The Somerville, Mass.-based startup, founded in 2017, has raised $7.5 million to date, including $4.5 million in a seed round, Grama said. It is currently raising $6 million to support field trials of its hardware.
Transaera’s core technology is a proprietary material that covers the warmth pump’s heat exchangers, which resemble a automotive’s radiator. In Transaera’s DOAS, air entering the unit passes through a special material that removes moisture from the air. The drier air then passes to the evaporator coils, which cool the air to indoor temperatures.
Air conditioners and dehumidifiers generate heat within the technique of removing moisture from the air. Typically, this heat is wasted, but Transaera reuses it to remove moisture from the desiccant material on a porous wheel. As the wheel passes over the incoming air, it absorbs moisture. The loaded desiccant then spins away from the incoming air and thru the waste heat coming off the evaporator coils. The warm air carries unwanted moisture away from the air. In the winter, the system can reverse, helping to maintain indoor humidity as the warmth pump heats the incoming air.
Many other DOAS systems currently found on industrial roofs also use heat pumps to dehumidify supply air, but because they depend on low temperatures to condense water on coils, the air coming out of them will be too cool for what’s contained in the constructing (especially within the spring and fall, when temperatures will not be high enough to require air-con). The units then have to reheat the air, often using natural gas. “It’s a really inefficient, stupid way to do these dedicated outdoor air systems,” Grama said.
Transaera’s approach uses as much as 40% less energy than current top-of-the-line DOASs, he said. The company’s technology is currently on one industrial roof, but Grama said more shall be added soon. There is a few urgency: Because moisture removal requires a lot energy, it accounts for 1% of all greenhouse gas emissions, according to last examination. That’s about half of what aviation generates, a sector that is come under much greater scrutiny. Cutting energy use from dehumidification by 40% would cut that significantly. Dad would approve.

Flipkart co-founder Binny Bansal is leaving PhonePe’s board
Flipkart co-founder Binny Bansal has stepped down three-quarters from PhonePe’s board after making an identical move on the e-commerce giant.
Bengaluru-based PhonePe said it has appointed Manish Sabharwal, executive director at recruitment and human resources firm Teamlease, as an independent director and chairman of the audit committee.
Bansal played a key role in Flipkart’s acquisition of PhonePe in 2016 and has since served on the fintech’s board. The Walmart-backed startup, which operates India’s hottest mobile payment app, spun off from Flipkart in 2022 and was valued at $12 billion in funding rounds that raised about $850 million last 12 months.
Bansal still holds about 1% of PhonePe. Neither party explained why they were leaving the board.
“I would like to express my heartfelt gratitude to Binny Bansal for being one of the first and staunchest supporters of PhonePe,” Sameer Nigam, co-founder and CEO of PhonePe, said in a press release. His lively involvement, strategic advice and private mentoring have profoundly enriched our discussions. We will miss Binny!”

The company is currently developing washing machines for humans
Forget about cold baths. Washing machines for people may soon be a brand new solution.
According to at least one Japanese the oldest newspapersOsaka-based shower head maker Science has developed a cockpit-shaped device that fills with water when a bather sits on a seat in the center and measures an individual’s heart rate and other biological data using sensors to make sure the temperature is good. “It also projects images onto the inside of the transparent cover to make the person feel refreshed,” the power says.
The device, dubbed “Mirai Ningen Sentakuki” (the human washing machine of the longer term), may never go on sale. Indeed, for now the company’s plans are limited to the Osaka trade fair in April, where as much as eight people will have the option to experience a 15-minute “wash and dry” every day after first booking.
Apparently a version for home use is within the works.

Zepto raises another $350 million amid retail upheaval in India
Zepto has secured $350 million in latest financing, its third round of financing in six months, because the Indian high-speed trading startup strengthens its position against competitors ahead of a planned public offering next yr.
Indian family offices, high-net-worth individuals and asset manager Motilal Oswal invested in the round, maintaining Zepto’s $5 billion valuation. Motilal co-founder Raamdeo Agrawal, family offices Mankind Pharma, RP-Sanjiv Goenka, Cello, Haldiram’s, Sekhsaria and Kalyan, in addition to stars Amitabh Bachchan and Sachin Tendulkar are amongst those backing the brand new enterprise, which is India’s largest fully national primary round.
The funding push comes as Zepto rushes so as to add Indian investors to its capitalization table, with foreign ownership now exceeding two-thirds. TechCrunch first reported on the brand new round’s deliberations last month. The Mumbai-based startup has raised over $1.35 billion since June.
Fast commerce sales – delivering groceries and other items to customers’ doors in 10 minutes – will exceed $6 billion this yr in India. Morgan Stanley predicts that this market shall be value $42 billion by 2030, accounting for 18.4% of total e-commerce and a pair of.5% of retail sales. These strong growth prospects have forced established players including Flipkart, Myntra and Nykaa to cut back delivery times as they lose touch with specialized delivery apps.
While high-speed commerce has not taken off in many of the world, the model seems to work particularly well in India, where unorganized retail stores are ever-present.
High-speed trading platforms are creating “parallel trading for consumers seeking convenience” in India, Morgan Stanley wrote in a note this month.
Zepto and its rivals – Zomato-owned Blinkit, Swiggy-owned Instamart and Tata-owned BigBasket – currently operate on lower margins than traditional retail, and Morgan Stanley expects market leaders to realize contribution margins of 7-8% and adjusted EBITDA margins to greater than 5% by 2030. (Zepto currently spends about 35 million dollars monthly).
An investor presentation reviewed by TechCrunch shows that Zepto, which handles greater than 7 million total orders every day in greater than 17 cities, is heading in the right direction to realize annual sales of $2 billion. It anticipates 150% growth over the following 12 months, CEO Aadit Palicha told investors in August. The startup plans to go public in India next yr.
However, the rapid growth of high-speed trading has had a devastating impact on the mom-and-pop stores that dot hundreds of Indian cities, towns and villages.
According to the All India Federation of Consumer Products Distributors, about 200,000 local stores closed last yr, with 90,000 in major cities where high-speed trading is more prevalent.
The federation has warned that without regulatory intervention, more local shops shall be vulnerable to closure as fast trading platforms prioritize growth over sustainable practices.
Zepto said it has created job opportunities for tons of of hundreds of gig employees. “From day one, our vision has been to play a small role in nation building, create millions of jobs and offer better services to Indian consumers,” Palicha said in an announcement.
Regulatory challenges arise. Unless an e-commerce company is a majority shareholder of an Indian company or person, current regulations prevent it from operating on a listing model. Fast trading corporations don’t currently follow these rules.
