HEADS UP

THIS IS A SWEAT EQUITY DEAL

THAT MEANS A TON OF WORK, ZERO CASH, ONLY EQUITY.. FOR NOW

I REPEAT - A TON OF WORK, ONLY EQUITY FOR NOW

Why no pay you may wonder?

Well, we're not looking for just another employee, we're looking for an entrepreneurial spirit that want to join for equity with more stake and more to gain, more like a co-founder than an employee.

You would be joining the core-team of extremely talented professionals with decades of proven success, with a product in closed beta, and a product-launch around the corner.

So, have you been dreaming of starting a web3 company, but rather want to join a team where you can hit the ground running, this is for you.

We're on the lookout for the crème de la crème, the rare gem who shines brighter than the rest, prepared to face a challenge that's not just tough but deemed impossible by most. But you? You're the kind who sees "impossible" as just another word for "not done yet." Brace yourself for days when you'll be tempted to call it quits and seriously consider throwing in the towel.

Know this - no amount of equity or paycheck can match the heart and soul we're asking you to pour into this. Your drive should stem from a profound connection to our mission and a self-starter attitude that doesn't hinge on outside praise. You'll need that inner fire, a relentless zeal that drives you to action day in and day out.

We're after someone with undeniable grit—the kind that keeps you going when the going gets tough. And, of course, ready to tackle the relentless grind, putting in the hard work day after day. More than that, we need a doer who springs into action and gets things done—today, not tomorrow. No room for procrastinators or those lost in daydreams here.

Did all this scare you away - that's fine, better now than later.

Are you still here - Fantastic

Here is where it gets exciting
While it's all hands on deck with no immediate financial reward other than equity - the work, the team, the challenge, the product, and the mission is rewarding as h-ll, and we're setting our sights on a future where hard work pays off, really really good. Once we've secured funding or better yet, when our organic revenue covers team overheads and salaries, you'll see the tangible results of your sweat equity. It's crucial that you understand your role is key in reaching these milestones.

If this resonates with you, and you're nodding along, thinking, "That's totally me - I'm in," then you may just be the one we're looking for and should continue reading and hit that apply button.
