A small crew, at the edge of what technology can already do.
Why we exist, where we came from, and where we're heading.
How we work
Before we tell you who we are, here's what actually matters: how we work.
We review
What your business needs to hold up, before proposing anything. No blind quotes.
We define
The scope. You approve each stage before we move to the next.
We move forward
With a concrete deadline on the table from day one — store, site, or integration.
That's all you need to believe at the start. The rest — who we are and why we do this — you can read if you want, but it's not a requirement for trusting the deadline.
Why we exist
This isn't just about selling online stores. Access to technology was never split evenly, and with AI the market moves faster than ever — large companies have teams, budget, and now models that keep working while everyone else sleeps. Small businesses compete anyway, with their hands even more tied than before.
Lifting up your local economy: that's the whole mission.
Not for everyone — for whoever's crossing this stage and needs calibrated instruments, not a pitch.
Where this conviction comes from
> I grew up in a working-class neighborhood in Chile, with no head start — and learned early that the internet evens that out.
That's where I learned to look on the other side of the screen for what my surroundings didn't offer: piracy and P2P cracked my world open past my own neighborhood, and taught me to make opportunity where none existed. That same habit is what let me actually launch — I left Chile, lived in Argentina, and today work out of Rio de Janeiro. Exosfera became a formal company in Chile in 2020, but the path started earlier. Today, after two years also working as part of Jumpseller's internal team, at a real startup's pace, Exosfera has something solo freelancing never gave it: shape, structure, a tighter heading. We're still a crew of one — but the goal, going forward, is to add a global crew that shares the same conviction.
Who's behind it
Carlos Esparza
Founder · Exosfera
I started in a low-income neighborhood in Chile, with no head start. Today I work from wherever I choose to live — in my case, Rio de Janeiro — because the same technology we help install in other businesses is what let me cross that distance first.
Exosfera was born in Chile in 2020, but the road started earlier: years of independent work — under my own name, then under different brands — building sites, stores, and campaigns for small businesses. Every stage brought me a step closer to understanding what an entrepreneur really needs to sell online without getting lost in the technology.
That search led me to specialize in Jumpseller. Today, besides running Exosfera, I'm part of the platform's official support team — direct insight into how it works under the hood, and the best practices for implementing it. Almost two years there. A background in telecommunications engineering. Experience training people in digital marketing and e-commerce, including programs with public and private institutions.
In Brazil, we're Jumpseller's only official partner — the first real point of contact between the platform and businesses just discovering it.

What kind of project you can build with us
With us, you can get
- A Jumpseller store up and running in 10 days — platform, payments, shipping, and catalog, all handled, without the technical side becoming the barrier.
- An informational site or a custom system — the scope gets defined with a diagnosis, not blindly.
- Your site talking to the rest of your ecosystem — Google Tag Manager, analytics, a one-off integration.
What we don't do
- Fully custom design from scratch, with no base to build on
- Social media management
- Photo or video production
If that's what you're looking for, we're not your crew — and we'd rather tell you now than halfway through.
