A focused collaboration that lasts as long as the project needs. We validate the business, test assumptions, and ship either a PoC or a finished product. Every project is custom—design-only, team augmentation, or full product org. We've embedded for years, delivered end-to-end for crypto PSPs, staffed multinationals, and hired our own replacements without slowing delivery. You leave with a repo, demo, architecture notes, prioritized backlog, decision memo, working PoC, or clear next steps.
Venture Studio — Bring the Idea Pitch us.
We tailor capital, team, and equity to what moves fastest. Founders first, corporates and new companies welcome. We shape team, capital, and scope together—working session to map the opportunity, then build and iterate. You own the IP.
If your product touches chains, wallets, or tokens, we apply that experience precisely—architecture, data strategy, security, and compliant user flows. Token models are optional and justified on their merits. If your scope is off-chain or fintech-adjacent, we keep things simple and ship accordingly.

Subvisual is prototyping an interactive web-based solution for clinical data management, which is being used by oncologists and hospital staff. The team is refining the software using Java and Ruby.
The solution continues to receive positive feedback, which is largely due to Subvisual’s ability to translate complex specifications into a user-friendly platform. Other highlights include effective project management, high responsiveness, and a dedication to improving end-user experience.

client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the CEO of OncoStats, a company that builds software for oncology. We deal with structuring and restoring clinical information from doctors and nurses. Our systems analyze that information to better provide frequent decisions for a variety of patients.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Subvisual?
I needed to find a company that could help us develop the initial version of our software.
SOLUTION
What was the scope of their involvement?
In the beginning, we built the initial prototypes and then iterated a version that was interactive. Then, we built a demo version of the product, which we could present to medical staff who would use the software and give us feedback on their user experience. We use only web-based technologies. We mostly work on Java or Ruby-based languages. Subvisual allocated 1–3 developers and a lead designer. They scaled up and down as the project changed.
How did you come to work with Subvisual?
We were looking for a local company. Subvisual was a small team with a few years of experience. They had a good reputation for building something with an amount of care that isn’t what you usually see from a software development team. We came to them through a personal contact and started discussing what our company needed. They thought they could give us a good product. Subvisual currently holds part of OncoStats, so they are a partner in the company.
How much have you invested with Subvisual?
We have spent €100,000 over the course of our relationship.
What is the status of this engagement?
We started working with them at the end of 2014, and the work is ongoing.
RESULTS & FEEDBACK
Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?
We’re starting to install our software in a couple of hospitals in Portugal. Most of the feedback is from doctors that have been using our software. The feedback has been tremendously good
How did Subvisual perform from a project management standpoint?
We used Slack to communicate and Trello for project management.
What did you find most impressive about Subvisual?
They have a good work method that is based on evidence. These evidence-based methods are used by other successful companies, like Google design sprints and OPR. They’re a relatively small team in a work environment that is very familiar, so it’s very easy to communicate. I was able to give feedback directly to the designer, which is only possible when you work with a small team.
Are there any areas Subvisual could improve?
We’re dealing with a complex subject matter. A software company like Subvisual will not have much experience building software for healthcare. Subvisual wasn’t familiar with a lot of the vocabulary that we used. They improved in that as the project progressed, but it could still be better.

Our Story
Since 2012, we've built products and companies that matter. We're a product and venture studio, not just a dev shop. We believe founders come first, every project is custom, and quality doesn't require templates. We've backed ventures that raised over $100M, embedded with multinationals, and shipped everything from crypto infrastructure to fintech platforms. Remote-first from Portugal, working globally. What sets us apart: we're as invested in the company you build as the code we ship.
