Great hiring takes both speed and judgment. Elly.ai built a platform where AI and expert recruiters work the same search together. Congrats on launch day @kristenhabacht
Big launch day🐶

NEW: The AI Data Center "Boom" is Kinda Fake..
But the power bottleneck is still very real.
Inside the energy company using rocks & sunlight to fix AI’s power problem right now.. not in 10 years: @ExowattEnergy
Most "announced" data centers will never get built (ahem, Stargate). The ones that do? Running on gas generators. And the U.S. grid has no answer for what’s coming.
Hannan Happi, CEO & Co-Founder of @ExowattEnergy, joins Sourcery for a rare facility tour of their 40,000 sqft Miami HQ — walking us through the tech, the team, & why the AI power crisis is far worse than the headlines suggest.
Exowatt has raised $140M from a16z, Atomic, Felicis, Sam Altman, Leonardo DiCaprio, Starwood Capital, Thrive Capital, & more, all betting on a deceptively simple idea: concentrate sunlight with Fresnel lenses, store the heat in rocks at 1,000°C, and dispatch electricity on demand. 24 hours a day, no grid required.
Their P3 system is built from sand, dirt, and steel. Like a large magnified glass and a rock. No lithium. No cobalt. No China. Target cost: 1 cent per kilowatt hour.
In this episode:
→ Why most announced data centers are phantom projects
→ The real bottleneck that replaced GPUs: skilled labor
→ How a 200-year-old engine is at the heart of their stack
→ What hyperscalers actually say about sustainability (it's not pretty)
→ Lessons from Tesla on iteration, modularity & vertical integration
→ Why Miami — and why now
With a 90+ GWh demand backlog and commercial deployments live in 2025, this might be one of the most important energy companies emerging in the AI era.
Founded in 2023 by Hannan Happi & Atomic CEO @jackabraham, Exowatt's mission is to make sustainable renewable energy always available and almost free.

My 8 Sleep has easily been the best health investment I've made.
Per my whoop data:
Hours slept vs hours needed: 72% to >91%
Sleep efficiency: 85% to >93%
Overal Sleep performance: 72% to >90%
Excited for an even more powerful version @m_franceschetti !

Did we mentioned it's built in Miami?
Exowatt launches today! ☀️
The power requirements to scale AI are astronomical. Within a decade AI will require 650TWh of new power generation – more than the electricity demand of South Korea. In the U.S. alone, data centers will require the equivalent amount of electricity to power 40 million households by 2030.
Exowatt P3s can generate electricity at scale at just a $0.04 LCOE and with entirely renewable tech. That’s lower than the cost of most fossil fuels and doesn’t account for subsidies. We have already amassed a 1.2 GW backlog, worth $Bs from the mega tech hyperscalers, energy and data center companies.
The system works by capturing the sun’s energy in the form of heat, storing it in a heat battery and converting it to electricity via a heat engine even when the sun is no longer out. This changes the economics of solar by solving a problem called the “Duck Curve” where all conventional solar producers are forced to sell their power at the same time while at maximum output, driving the electricity cost sometimes to zero or negative intraday and leaving no supply at night. Data centers need to operate 24/7 and typically have 60% of their OPEX from energy costs, so an inexpensive and ever available alternative is very important to them. Data centers are straining to bring capacity online and without solutions like Exowatt, are being forced to turn to fossil fuels like coal, oil and natural gas.
We hope you’ll join us in pushing forward an abundant and non fossil fuel powered future!⚡️

At the time of this, I joked that Satish @Redpoint had been on the Midas List 6 more times than me (6 vs 0). Now 7. A rare interview with the rare VC who never VC brags, tweets, blogs, pods. Hear how he invested in Snowflake @ $50m, what makes a great leader vs. manager, and more

Most subscription companies don’t realize that half of their customer churn is accidental and can be recovered. @ButterPayments 🧈 boosts top-line for consumer and SaaS businesses by ~10%, addressing this ~$440B problem. @ShenLucinda @axios with more here axios.com/pro/fintech-deals/…
