COI Energy solves a conundrum: Letting businesses sell unused electricity — catch it at TechCrunch Disrupt 2025
When it comes to supplying electricity to large enterprises with multi-building campuses, the allocation system is archaic. Unlike homeowners, who pay for what they actually use, campuses buy a standard monthly capacity. This capacity must, by common-sense necessity, be based on max usage needs. This is true even if the company only consumes such max usage rarely, like a single busy season.
That was a situation that bothered the hell out of COI Energy founder and CEO, SaLisa Berrien. After earning her degree in mechanical engineering (and later an MBA), she spent 25 years as an energy engineer at major utility companies like PECO, Con Edison, and Exelon, as well as at a few clean energy startups.
Berrien chose this field because, as a child, there were times when her parents couldn’t pay their electric bill. “We were in the dark a lot. And as a kid, my self-esteem was low,” she told TechCrunch. Other kids who knew her situation teased her.
So when she got her degree and took a job with an electric company, “All my friends were like, ‘You’re crazy. That is a stagnated field. It’s a white, male-dominated, older-men field. Why are you doing this?’ And for me, it was personal, because I knew what it felt like being a kid,” she said. Berrien wanted to make electricity more efficient, more affordable, more available so no child ever went without.
She worked on customer operations, smart grids, clean energy programs.
“As an engineer, I would go in and make recommendations on how they could improve the energy performance of their buildings, how they can eliminate bottlenecks on production lines,” Berrien said.
She learned how to use big data to optimize energy efficiency. But no one was addressing the basic problem: Companies were reserving, and paying for, far more energy than they used.

Commercial customers continually asked her why they were being overcharged. “I agree,” she said. “Why can’t you just pay on demand for what you’re using?”
Berrien’s answer resulted in three patents (and counting) and founding COI Energy on that tech, assembling a team that includes building management, energy engineers, and a former energy exec. She hired people skilled in everything from regulation to pricing.
COI’s solution is a marketplace where enterprises within the same utility company can sell some of their energy allotment when COI’s data predicts they won’t need it. COI is a Startup Battlefield Top 20 finalist and will be pitching its tech at TechCrunch Disrupt 2025, this week in San Francisco.
COI installs a patented energy gateway at every customer site to measure energy usage. It ties into the building’s systems and into SCADA systems. It is hardware-agnostic, meaning it can work with any existing utility or building energy system, Berrien said. After collecting data for a period, the platform predicts how much electricity a company will truly require. “We can predict out 90 days,” she said.
The enterprise can then determine how much of the unused energy it would like to release. COI pays the businesses for that capacity, and buyers on the marketplace pay COI to obtain it. “If a customer gives us 100 kilowatts, we will pay them for that 100 kilowatts, and then the buyers would buy that from us.”
COI is still in its pre-seed stage, having raised $3.5 million from investors like former Talen Energy exec Paul Farr, Morgan Stanley Inclusive and Sustainable Ventures, Kachuwa Impact Fund, Chloe Capital, and some crowdfunding on Republic.
The startup is, however, already generating revenue through five pilot customers, all of whom have a minimum of 50 buildings. It is operating in California, Florida, Massachusetts, and New York, and has a waitlist. Plus, Berrien said, COI is in talks to be a solution provider to Switzerland as it enacts a national energy policy where businesses and homes can share capacity, starting in 2026.
Moreover — remembering her plight as a little girl — Berrien’s startup has dedicated 1% of the savings that the businesses earn on the platform to be donated to nonprofit organizations that help the underprivileged with their energy needs. These are organizations that help pay bills, provide weatherization, and offer energy programs like solar.
“We’re paying it forward with what we call Kilowatt for Good,” Berrien said.
Her goal is to offer tech that helps overwhelmed energy systems now. “Instead of wasting capacity, you’re sharing it. So we’re making the planet better. We’re making our bottom lines better. And then at the same time, we’re helping and uplifting our communities,” she said.

Waymo starts autonomous testing in Philadelphia
Waymo is adding another four cities to its growing list of robotaxi rollouts. The company announced Wednesday it has begun testing its autonomous vehicles (with a safety monitor) in Philadelphia, and that it will start manual driving to collect data in Baltimore, St. Louis, and Pittsburgh.
Waymo did not offer a timeline for when it plans to launch commercial services in those locations, nor do we know whether the Alphabet-owned company will partner with other companies to operate robotaxis in each one. That has been the move in cities like Atlanta and Austin, for example, where Waymo has partnered with Uber to advance its robotaxi rollout.
But the new locations join a list of over 20 cities where the company is either offering rides, prepping a commercial launch, or testing. Waymo is also now offering rides on freeways in Los Angeles, Phoenix, and the San Francisco Bay Area. The company plans to be doing one million rides per week by the end of 2026.
Waymo has done all this while claiming to be operating at a level five times safer than humans, according to data the company recently released.
But the expansion has not come without its issues. The National Highway Traffic Safety Administration is investigating how the company’s vehicles operate near school buses, after a Waymo was filmed driving around a stopped bus in Atlanta in September.
This week, Austin news outlet KXAN published a report showing Waymo’s vehicles have driven past school buses that were in the process of unloading or loading children multiple times — including after Waymo claims to have shipped software updates to address the problem.

Spotify Wrapped 2025 adds its first multiplayer feature with ‘Wrapped Party’
Spotify Wrapped is back. After last year’s widely criticized flop that included an AI podcast as its highlight, the streamer’s highly anticipated annual review feature has returned to its roots. This year, Spotify is doubling down on what it knows works best: deep dives into your streaming data, creative experiences, messages from favorite artists, and other social features.
The company claims that Wrapped 2025 is its biggest, as it’s introducing nearly a dozen new features in addition to its old standbys, like top songs and artists. Plus, it’s offering more visibility into users’ data than in years past. For the first time, Spotify Wrapped is adding a live multiplayer feature to compare your listening data with friends.
Wrapped Party, Wrapped’s first live interactive experience, allows you to invite up to nine friends to compare listening stats.

Also new this year, your Top Songs Playlist will include the play counts for each of the top songs, so you can actually see how much time you spent with your favorite tracks.
Other standout features this year include an interactive Top Song Quiz, a Listening Age feature, and Wrapped Clubs, which match you to one of six unique listening styles.
The company believes these additions will not only bring back the personalized, engaging experience that users have long expected from Wrapped, but will take it a step further by making it more interactive than before.
In the Top Song Quiz, for instance, you can try to guess which top song soundtracked your year before seeing the results.

The new interactive Wrapped Party feature isn’t just about comparing the personal streaming data you’ve already received to your friends’ data, as that’s something people already do on social media. Instead, the feature presents unique data stories for your group, like who’s the “most obsessed fan,” the “early bird,” the most “picky listener,” or even something as nice as the “dinner table explainer,” meaning the person who listens to the most news podcasts.

Spotify says these awards update dynamically every time you join a Wrapped Party, so no two sessions are ever the same — even if you run through them again with the same group of friends.
The new Wrapped Clubs, meanwhile, will group you into one of half a dozen listening styles, like the “Soft Hearts Club,” the “Club Serotonin,” the “Full Charge Crew,” the “Cosmic Stereo Club,” and others. You’ll also receive a role in the club based on your listening data. You might be a club leader if your listening choices strongly matches the club’s values, a scout if you’re always seeking out new releases, or an archivist if you listen to music from past eras.

Another feature, Listening Age, compares your 2025 music listening to others in your age group. To calculate your age, the feature considers the release years of the tracks you listen to most. From there, it identifies the five-year span of music that you engaged with more than other listeners your age.

As in prior years, you’ll see your top songs, top artists, top genres, and, for the first time, top albums. If you engaged with audiobooks and podcasts, you’ll see metrics for those as well. Artists, writers, and podcasters will have their own version of Wrapped as before. And top fans will again receive video messages from their favorite artists, podcasters, and, now, authors.
You’ll also receive a playlist of your top songs of the year, as before.

What you won’t find in this year’s Wrapped is any feature that advertises it was made with AI.
In a press briefing on Tuesday, Spotify’s Senior Director of Global Marketing, Matt Luhks, admitted the company received a “lot of feedback” about its 2024 AI-focused Wrapped experience, saying it was a “mix of positive and ‘more constructive feedback,’” despite the feature driving more engagement than prior years.
“We take all of that in. We use that as information, insights, [and] inspiration for how we approached Wrapped this year,” he said in a press event ahead of today’s launch.
“What our users tell us about Wrapped means a lot to us, so it was really informative in how we approached Wrapped this year. And what we tried to build was the most creative, most innovative, most engaging Wrapped ever,” he added, setting a high bar for the 2025 edition of the now 11-year-old annual year-in-review feature.
“We’re the original and, we believe, still the best,” Luhks said.

Still, AI was a part of the Wrapped experience. Though the company claims the overall experience was not made with AI, it does leverage a LLM (large language model) to add a storytelling layer to Wrapped’s facts and figures, and natural language summaries in other parts of its experience, looking back on your data.
Spotify’s attempt to fix Wrapped after a notable stumble comes as the streamer faces increased competition from Apple, Amazon, YouTube, and others, which have all launched their own annual review features, inspired by Wrapped.
“Everyone seems to have their own version of Wrapped. Now, there’s a lot of reviews and replays and rewinds out there, but we believe that Wrapped still sets the bar for these year-end recaps,” Luhks said.
Along with the consumer experience, Spotify shared its top artists, songs, albums, podcasts, and audiobooks for the year, with top winners that included, respectively, Bad Bunny (top song and album), Joe Rogan (“The Joe Rogan Experience” podcast), and Rebeca Yarros (author of “Fourth Wing”).

Nothing looks to its community to raise $5M, wants to be ‘IPO-ready’ in 3 years
Hardware maker Nothing is letting its user base buy its stock as part of a new community investment round of $5 million. The new round, which opens on December 10, will enable consumers to buy the company’s shares at its Series C valuation of $1.3 billion.
The company said it has so far raised $8 million in total from over 8,000 people across two previous community investment rounds. It held its first community funding event in 2021, aiming to raise $1.5 million.
“This isn’t about raising capital, it’s about giving our community/fans a chance to invest while we’re private and join us on the journey,” a spokesperson for Nothing told TechCrunch.
Community investors have a rotating seat on the company’s board, but it is unclear what else they get for investing in the company through such rounds.
Nothing raised $200 million in its Series C back in September from investors including Tiger Global, GV, Highland Europe, EQT, Latitude, I2BF and Tapestry. The company has raised $450 million to date.
The community round comes as Nothing makes changes to its corporate structure as it tries to increase its share of a smartphone market dominated by giants like Samsung and Apple. The company is spinning off its budget CMF brand, and plans to explore AI-centric devices while it keeps building smartphones and audio products. And Nothing claims it crossed $1 billion in cumulative revenue this year, up 150% from 2024.
The startup is working to be “IPO-ready” in three years, CEO Carl Pei told TechCrunch in an email. “The timing will depend on market conditions and what makes sense for the business at that point in time,” he said.

“What’s important is that we’re already operating with that discipline now. We’re building the systems, the governance, the financial discipline that a public company needs. It forces us to think longer-term and make smarter decisions that prioritise sustainable growth,” Pei added.
It’s not clear if Nothing aims to raise another round before an IPO. When asked about its fundraising plans, a Nothing spokesperson said the company is not thinking about raising capital immediately, but it wouldn’t be averse to those conversations.
Those interested in investing in the community round can use platforms like Wefunder and Crowdcube to participate.
