If you’re making a new gas turbine, how big should it be?
Decades ago, the computing industry figured out that large arrays of blade servers were both cheaper and more reliable than a small number of expensive mainframes.
Yet the energy world is still largely powered by gigantic “frame” turbines that are hard to make and difficult to install.
I think the future of energy—particularly for off-grid “behind the meter” generation —is small modular production.
But how small should you go? If you go too small there is a big loss in efficiency (due to things like higher relative blade tip losses).
But there’s a sweet spot in the 40-50MW range where the turbine has most of the efficiency of a gigantic unit yet is also much more manufacturable and deployable. This is the sweet spot is in total cost per unit energy, inclusive of capital expenditure.
This is why Superpower sits at the ever magical 42MW.
Payloads on a ride to space. 🚀
Vikram-1's Test Flight-1, Mission Aagaman, carries multiple technology demonstrations: @grahaaspace's SOLARAS S3 satellite, Cosmoserve Space's in-orbit robotic arm Embrace, an in-orbit demonstration from Germany's @DCUBEDspace, and Skyroot's own SCOPE satellite.

🚀 Announcing Vikram-1 Test Flight-1: Mission Aagaman, India’s first private orbital rocket launch.
📍 Satish Dhawan Space Centre, Sriharikota
🛰️ 450 km, 60 degree inclination, Low Earth Orbit
📅 Launch Window: July 12 – August 4, 2026
Vehicle is now fully stacked at India’s historic First Launch Pad (FLP).
The countdown to a new chapter in Indian spaceflight begins.
One rocket, a billion believers. Thank you ISRO & INSPACe for enabling this..

Vikram-1's Stage 1 is stacked at the First Launch Pad, Satish Dhawan Space Center, Sriharikota. 🚀
For India, this is the first time a privately designed, developed, and manufactured orbital rocket has been stacked on this pad.

The dura is the brain's armor: a membrane so tough that a surgeon normally cuts through it with a scalpel. For the first time in our clinical trials, we inserted the electrode threads of our implant straight through the dura and into the cortex, keeping the dura intact.
Here's how we did it 🧵
Rocket Lab is acquiring Iridium Communications Inc – one of the most transformative deals in the space industry.
By combining our launch capability and satellite manufacturing with @IridiumComm’s global satellite communications network and rare spectrum, Rocket Lab becomes a fully integrated, self-launching, tier-1 space power, delivering critical communications capability to millions of users worldwide.

Leak shroud testing – the six-sided metal enclosure around the nozzle is designed to simulate the engine bay of the integrated rocket to identify any fuel or oxidizer leaks during a full mission duty cycle burn.
This is a key test to help retire risk for stage static fire and flight.🚀
The VICTUS HAZE mission explained.
Phase 1: Launch on demand 🚀 The @USSpaceForce's @USSF_SSC called, told us to launch, and just 16 hours 42 minutes hours later, Electron successfully left the pad from LC-1.
Phase 2: 🛰️ With Pioneer spacecraft checkouts complete 34 hours ahead of schedule, the chase is on to rendezvous with another satellite on orbit; one that doesn't want to be found.
It’s been a minute.
2015–2018
- Exited FreeCharge. Spent time learning and investing.
- Pondered about: Why can't trust be rewarded? Started with $1M of personal capital.
- Launched CRED to reward people for paying credit card bills on time.
2019–2025
- Built a system run by a team that values ownership, judgment, and craft.
- Grew from 0 to 17M members by aligning incentives with behaviour.
- Built several products during COVID lockdowns.
- Raised $900M+ from global investors. Did 4 ESOP buybacks.
- Made Indiranagar and IPL ads slightly more interesting.
- Received a full stack of regulatory licences.
- Lost 35 kilos.
- Scaled from 0 to ~$325M ( ~₹3,200 crore) in annual revenue across payments, lending, insurance, commerce, wealth, and credit cards.
2026
- First profitable quarter (yet occasionally asked what our business model is)
- Raised another $900M from Meta in primary and secondary capital.
- Announcing our 5th ESOP buyback.
Today
CRED is ready for its next phase. I am stepping back and @miten steps in as interim CEO, partnered with an incredibly talented team. He has been heading strategy and finance and suffering me since 2020. I’m stepping away from the operating role and will continue as a shareholder. My commitment doesn’t change. Just the role.
Extremely grateful to our members, partners, regulators, and investors who made this possible. And to our board, Shailendra, Micky, Saurabh for their extraordinary conviction.
Team CRED, I’ll still expect you to be a 10x version of yourselves.
As for me, I’ll be joining Meta to lead WhatsApp globally.
Meta comes in as a minority investor in CRED. No access to member data.
While it’s come very far, the delta between WhatsApp today and its full potential is massive. I look forward to working with Mark, Chris, and the leadership across Meta for the next step in WhatsApp’s journey. Will, thank you for scaling something the world relies on quietly, and for making this transition smooth.
Onwards.
Continuous sunlight is scarce on the Moon unless you know where to look. 🌑
The lunar poles contain "peaks of eternal light," areas bathed in near-continuous sunlight. Power Tower mounts on Blue Moon MK1's top deck and extends solar arrays to 26 meters total height to capture that energy and deliver sustained power for Moon Base operations.
Check out this video of Power Tower during a successful deployment in an analog lunar environment.
The infrastructure era of lunar exploration starts now.
The Space Force called, and we launched. From call up to lift-off in just 16 hours 42 minutes 🎯 Rocket Lab has made history - the fastest response time ever for a @USSF_SSC Tactically Responsive Space mission.
I haven't read this for about 10 years, but I just looked at it after someone linked to it and I was surprised how many of these things are starting to happen. Still no next Steve Jobs yet though.

The shortest distance ever discussed in science is the Planck length. It's the shortest distance that can be measured. Our universe's pixel size.
So how small is it? A sphere with a Planck length diameter is to a human egg cell what a human egg is to the observable universe.
