Congratulations to portfolio company @boltohq on its recent $5.1M seed round! 👏

As the go-to platform for global recruiting, they’re streamlining talent sourcing, payroll, and HR into one seamless solution. Learn more!⬇️

[Mern Singh @mrinalsingh02]

Today, I'm thrilled to announce @BoltoHQ's $5.1M seed funding round from Y Combinator, General Catalyst, and others.

We launched just under 8 months ago.

Since then, companies of all sizes, from seed stage to publicly traded enterprise, have adopted @BoltoHQ as their go-to solution for global recruiting.

Why?

@BoltoHQ consolidates the global recruiting stack under one roof:

- AI-enabled talent sourcing and matching
- Global Payroll
- EOR

This enables us to offer significantly lower prices than our industry peers and save companies countless hours.

Now, we're going after our bigger vision – building the world's first fully end to end global recruiting and HR platform.

This year is going to be our biggest yet.

Special thank you to some of our early customers for taking a chance on a fresh startup:

@AdiAgashe and @neel_a_mehta from @Fiber_AI
@francistogram from @MeetAssembly
@pareto_ai
@rebetapp

Huge thanks as well to our investors for believing in us:

@DaltonC from @YCombinator and the teams at @GeneralCatalyst, @Amino_Capital, @MoradoVentures, @AlumniVentures, and of course our amazing angels!

Finally, stay tuned for a full overview of the reimagined @BoltoHQ product coming later this week 👀

Now, back to building.

In this video, @AaloAtomics CEO Matt Loszak puts nuclear fuel to the test in collaboration with UT Austin and its UZrH nuclear reactor.

Watch the full video below!

[Matt Loszak @MattLoszak]

This nuclear fuel (UZrH) has an incredible property: It can't melt itself down.

But why isn't it used in reactors everywhere?

In this video, we visit UT Austin's UZrH nuclear reactor and put it to the test: we actually TRY to make it melt down. Then we explore the history of UZrH, the challenges of using it in a power-generating reactor, and the upside if these challenges are overcome.
