Branch Energy puts your parking space to work
A battery beside a Texas business can earn its keep on the grid. Branch Energy turns that small patch of land into lower electricity bills and backup power - then pays for the equipment itself.
EnergyHub is building a power plant in your thermostat
The Brooklyn software company turns thermostats, batteries and electric cars into capacity utilities can call on. Its revealing lesson: a useful gadget becomes valuable infrastructure when enough people agree to use it together.
Andrew Webber Found a Second Market for Electricity
A newspaper story about California paying Arizona to take surplus electricity sent a former Marine and Wall Street investor down an unlikely path. His answer was to bring computing to the power - and teach data centers when to get out of the grid's way.
The $100 Box That Turns 400,000 Homes Into a Power Plant
A former commodities trader noticed homeowners were flying blind on their own electricity. So he sold them a $100 box - and started wiring 400,000 basements into a grid-scale power plant.
Emulate Energy
Emulate Energy is a Lund, Sweden cleantech company that builds white-label software turning everyday household devices - EV chargers, heat pumps, home batteries and solar inverters - into a coordinated, grid-ready fleet. Its platform lets utilities, retailers and grid operators connect, control and monetize distributed energy resources: cutting household bills, shaving grid peaks and unlocking flexibility-market revenue without asking customers to change tariffs or behaviour. Founded in 2020 on control-theory research from MIT and Lund University, Emulate runs live programs across Europe and the US.
Shwan Lamei
Shwan Lamei is co-founder and CEO of Emulate Energy, a Lund- and Boston-based software company that turns everyday household devices - heat pumps, EV chargers, home batteries, solar inverters - into a coordinated 'virtual battery' that utilities can dispatch on flexibility and balancing markets. Trained as an industrial engineer at Lund University, he spent 15 years in industrial B2B sales and corporate development at SWEP and Dover before starting Emulate in 2020 with a childhood friend whose MIT postdoctoral research became the technical seed of the company. In April 2025 Emulate closed a EUR 5M Series A led by Helen Ventures to scale its DER orchestration platform across Scandinavia, the DACH region and the United States.
Rahul Kar
Rahul Kar is the founder and CEO of Hammerhead AI, a Redwood City startup that uses reinforcement-learning control agents to squeeze stranded power out of AI data centers. After helping build and scale AutoGrid - the distributed-energy software pioneer acquired by Schneider Electric - Kar launched Hammerhead in November 2025 with a $10M seed round led by Buoyant Ventures. His thesis is blunt: the real bottleneck for AI is not chips or models, it is power, and most data centers run at 30-50% of their allocated capacity. Hammerhead's ORCA platform orchestrates power, cooling, and compute in real time to unlock roughly 30% more usable capacity without touching the grid.
Sidewalk Infrastructure Partners (SIP)
Sidewalk Infrastructure Partners (SIP) is an infrastructure developer and holding company that builds and operates businesses reshaping how energy and digital systems work together. Founded inside Alphabet in 2017 and spun out as independent in 2019 by Sidewalk Labs veterans Jonathan Winer and Brian Barlow, SIP raised $400 million in 2020 backed by Alphabet and the Ontario Teachers' Pension Plan. It identifies bottlenecks in physical infrastructure, then pairs technology with capital to create new operating companies - most recently Renew Home, a roughly one-gigawatt residential virtual power plant, and Verrus, which designs large-scale data centers that flex their grid draw on demand.
