Skyroot Aerospace became India’s 1st Space Unicorn

[catalyx space @catalyxspace]

Most founders start in a garage.
We started on a rooftop.

Just an idea, some hardware, and 0 money.
7 months later, we launched a spacecraft.

This is that story.

Happy Holi from Team @catalyxspace

[Rifath Shaarook @riftron_]

Anti-Valentine update nobody asked for.
Shipped anyway.

Next big thing: April 2026.

Can’t say what it is (yet).
But you’ll want to see it.

Want in early → join the waitlist.

RT @catalyxspace: CatalySpace’s first mission is now officially listed in the U.S. Space Force’s BR-DGE Rideshare Program.

This marks the…

[Rifath Shaarook @riftron_]

Vertical integration gets thrown around a lot.
But this is what it actually looks like.

Catalyx facility. Coming soon.

Life at Catalyx :)

You should join.

Superheroes are real.
They just work in silence.

So, we made this for them.
And maybe… for you too.

[Rifath Shaarook @riftron_]

Superheroes have always existed.

From the first wheel to the first flight, from computers to AI, it was them all along, changing the world.

And the truth is, they still live among us.

This is our bat signal to each one of them.

It’s time to build again.

[Keerthan Chand Aluvala @ChandKeerthan]

1 year ago, @riftron_ and @heysaqh went to the US for the first time to join the @Techstars Accelerator. We took the risk, pushed boundaries, and built what @catalyxspace is today. A big announcement coming tomorrow. Can’t believe how far we’ve come in just a year. Stay tuned.

[Rifath Shaarook @riftron_]

Funding Announcement: @catalyxspace has raised a $5.4M seed round to build the complete back-end infrastructure for space — enabling both upmass and downmass for the next era of orbital logistics. This brings our total funding to $7.1 million.

Exactly one year ago, my friend @heysaqh and I left everything behind in India and arrived at LAX, hoping to build our new space company in the U.S. Meanwhile, our friends @clinton_atspace and @ChandKeerthan focused on developing spacecraft hardware back home in India.

We joined the @techstars space accelerator and later @hf0 , raising a $1.7M pre-seed round in December 2024 from HF0 and @fdotinc, before moving to San Francisco — the city I love most.

The entire team relocated to SF in January for HF0. Since then, we’ve 5X’d our revenue, built a re-entry capsule, launched our first spacecraft, and completed our drop and landing tests.

We’ve grown to a 20-person team and begun constructing a new spacecraft manufacturing facility in India.

Today, we’re thrilled to announce our $5.4M seed round, led by @outlandervc , with participation from @ArkaVentureLabs, Lex Reddy, KDX, @scaletogether,
Higher Life Ventures, @NiveshaVentures, Pranatech, Bria, @hf0 and @Techstars.

Thanks to the Almighty for everything and everyone who has believed in us.

This round will help us demonstrate our next-generation re-entry and landing technology, scale our GTM, and execute upcoming missions.

Multiple missions are already lined up — each bringing us closer to making orbital logistics as seamless as air cargo.

We’re not just launching satellites — we’re building the operating system for space logistics.

Time to get back to building, testing, and launching.

The future of space isn’t one-way.

Upmass. Downmass. Infinite possibilities.

[Sid @SidHaldar_]

In SF I had the opportunity to have a conversation with @riftron_ from @catalyxspace or as I like to call him - The Indian Elon Musk

In our conversation we talk about:

- How he’s creating the OpenAI moment for space
- Growing up in his father’s science lab
- Accidentally building the world’s lightest satellite at age 16
- The team behind Catalyx
- SpaceX agreement
- Bringing space to SF

Since then I've gotten to know the team much better and they're the hardest working yet most humble people I've seen.

Super grateful for this chat and to have been around their energy.

Catalyx Space Leadership Update

We’re strengthening our leadership bench to accelerate R&D and scale operations.

-Clinton (@clinton_atspace), Co-Founder and previously VP of Mechanical Systems, is stepping in as Chief Technology Officer (CTO) to lead tech and drive the next generation of Catalyx Space systems.

- Niharika (@niharikanaveen), previously Chief of Staff, is stepping in as Chief Operating Officer (COO) to oversee operations as we scale globally.

Catalyx is entering a new phase: from rapid prototyping to full-scale execution. With this leadership in place, we’re doubling down on speed, integration, and impact - and we’re ready for what’s next. 🚀

[Rifath Shaarook @riftron_]

We did it! @catalyxspace has successfully completed our capsule drop and landing test from 16,000 ft in Nevada.

Our re-entry capsule, Rex, nailed the landing, proving our critical subsystems. It was fully vertically manufactured.

Next up: on-orbit demo in next 12 months.

Watch Rex in action 👇🚀

[Rifath Shaarook @riftron_]

@catalyxspace has successfully conducted a second mid-air drop and landing test of its re-entry capsule this morning in Nevada.

This time with better on-board and ground tracking cameras. Crazy mission video coming out soon.

We ship space hardware as if it’s software. Fast AF.

[Founders Inc @fdotinc]

Catalyx is bringing Space to SF.

If you've always wanted to build in orbit, they'll ship:
> hypersonic sensors
> bio pharma tests
> papa john's pizza

And they can bring it all back to Earth, insane.

Their DMs are open ⬇️
