[Matias Nisenson @MatiasNisenson]

🥰 two @myelinvc portfolio companies now collaborating:

@AstroMechanica × @TerraformIndies

[Matias Nisenson @MatiasNisenson]

Go buy a Throne!! Congrats @ScottHickle!

[Matias Nisenson @MatiasNisenson]

I'm not a big sports person, but we invested in this company (Arcturus) because the tech was v cool!

Let's see if they can get the big leagues to adopt it.

[Matias Nisenson @MatiasNisenson]

We backed another very cool company at @myelinvc: Material.

Most hardware is poorly designed for one boring reason: batteries! @Material_HM hopes to change this.

Short thread 👇

[Gaston @maffeigaston]

Energy storage is getting a real overhaul, and at @myelinvc we’re proud investors in @Material_HM.

They make batteries a design enabler: shape the cell to match the product, not the product to match the cell.

Can’t wait to see what can be built when batteries stop being the constraint that defines the device and engineers get a better, faster, denser option in their toolkit.

[Martin Varsavsky @martinvars]

In San Francisco! Other than building my companies I also invest and mentor extraordinary founders. DM open today.

[Myelin VC @myelinvc]

@becoming_ai @MatiasNisenson 🙏🏻🤝 Congrats on the launch!

[Becoming @becoming_ai]

Incredibly grateful to have had your support from the beginning. Especially given the subject matter experts you and your team are. @MatiasNisenson

[Matias Nisenson @MatiasNisenson]

One of the coolest companies we’ve backed at @myelinvc is finally coming out of stealth.

@becoming_ai launches today. If we can predict how organisms change over time, it changes everything: medicine, aging, and treating disease at the root.

Congrats @divyacohen and team!

[Nexo @Nexo]

Nexo has acquired @buenbit, one of Latin America’s leading digital asset platforms – a major milestone in our global expansion strategy.

Buenbit is a cornerstone of crypto adoption in Argentina and Peru, known for its user-friendly, compliance-first approach. 🧵

[Garrett Scott 🕳 @thegarrettscott]

We have three big @pipedream_labs announcements today. The 3rd is the most ambitious project we've ever attempted.

Here’s a quick summary thread:

[Garrett Scott 🕳 @thegarrettscott]

On Monday, we are making the biggest Pipedream announcement yet.

Thanks to everyone who helped us get here, can't wait to show y'all what's next!
(Sound on 🔊)

[Matias Nisenson @MatiasNisenson]

Shit just got real (pun intended). Congrats @ScottHickle!

Myelin II (@myelinvc) portfolio company @ThroneScience closes a $4m seed round!

[Matias Nisenson @MatiasNisenson]

This is @outpostspace, one of our portfolio companies and easily one of the coolest.

Send payloads to space and bring them back to Earth.

Watch the video to see their autonomous paraglider with landing precision of 5 meters in action.

[Myelin VC @myelinvc]

Let’s build airplanes!

[Ian Brooke @ianbrooke]

The best part about fundraising is when it ends and I can get back to building.

This raise marks the end of just working on engines and the start of building airplanes — couldn’t be more excited

[Freethink @freethinkmedia]

What if we connected a ‘delivery tube’ to every home?
That’s the idea behind @pipedream_labs - a logistics company that is trying to replace big, inefficient delivery trucks with robots and tunnels.

00:00 – This is a tube that grants wishes
01:48 – Welcome to Hard Reset
03:23 – Follow us to Pipedream Labs in Austin, Texas
04:02 – Building a city-wide network of tubes
04:55 – Pipedream Labs’ prototype graveyard
06:30 – Last-mile logistics is expensive and car-dependant
09:16 – Pipedream could make mail delivery safer
09:51 – The engineering problems with Pipedream
11:30 – How Pipedream is testing tube tech in Georgia
12:55 – Here’s how these pipes are installed
14:30 – Pipedream’s in-house prototype of this tech
17:50 – Pipedream’s long-term plan

[Matias Nisenson @MatiasNisenson]

If you’re a builder in Palo Alto, reach out to Martin.

You won’t regret it! 🐐

[Martin Varsavsky @martinvars]

I am in Palo Alto with time to see founders for early stage investments. DM me!

[Matias Nisenson @MatiasNisenson]

🥰 One of the greatest joys of investing in other founders is having more milestones to celebrate.

Today, we’re celebrating https://t.co/MmBKorRlvj and its incredible team, led by Vicki and Ruby. After lots of hard work, they’ve launched an innovative cat treat made from rabbit protein, without harming a single rabbit.

How do they do it? AI-powered precision fermentation. This technology uses yeast, programmed with the DNA instructions to produce specific proteins. These microorganisms are grown in fermenters, where they efficiently produce the target protein (in this case, rabbit protein) in a controlled environment.

The result is real, high-quality protein, identical to what nature provides, without killing a single animal.

Sounds like sci-fi but it’s real and you can get it for your cat at https://t.co/MmBKorRlvj
