We build software
that works.
An independent software studio on the Spanish Mediterranean. We design, build, and operate focused SaaS products and data APIs relied on by teams across Europe and beyond.
Built in-house. Operated daily.
Every product solves a specific, high-signal problem—from B2B deal intelligence and evidence-graded APIs to language mastery.
The daily multi-signal lead feed for B2B sales teams. Every morning, Fundup AI surfaces companies in motion: a funding round just closed, open roles are surging, a leadership seat is being filled, or an acquisition just landed. Each lead arrives with a clear reason to act and a real-time match against your Ideal Customer Profile. Not a database to search through; a feed you open every day, ready to act on today.

Peninsular Spanish for adults who are done with games. The plateau where most learners quietly quit, often with a 400-day streak still running. Suelto is built for what comes after: the grammar you avoid, the words you were never taught, the listening that still feels too fast. It finds the gaps between what you understand and what you can actually produce under pressure, and makes them usable. No streaks, no badges, just the truth about your Spanish.
VisitThe real tech stack of any company, with the evidence behind it. StrataDB reads what companies have to disclose and what they actually run: subprocessor lists, privacy policies, website code and job postings. Each source is graded and kept separate, never blended into a guess, and every claim carries its source and date. Search it on the site, or plug it into your own tools through the REST API and MCP server.
VisitThe investor database with the evidence behind every link. VCinfo tracks verified investors and their checked portfolio companies: declared on the firm's own site, seen in funding rounds, confirmed on the company's site. Each link is graded and kept separate, never blended into a guess, and every claim carries its source and last-checked date. Browse it on the site, or plug it into your own tools through the REST API and MCP server.

Our standard for software.
Every product we ship starts with a real problem and ends with software people rely on daily. We choose focus over feature bloat, and we measure success by whether users come back tomorrow.
Small team, full ownership
Every product is architected, operated, and supported by the same engineers. No handoffs, no account managers, no layers between user feedback and production code.
Ship daily, improve weekly
We deploy continuously and iterate based on real usage telemetry and customer conversations—not speculative roadmaps written quarters ago.
Revenue from day one
We build sustainable software that pays for itself. No vanity metrics, no artificial growth loops, and no indefinite runway burns.
Simplicity as a feature
If it takes a manual to use, we haven't finished building it. Our products are opinionated, fast, and obvious from the first click.
Want to build with us?
We're growing the studio with builders, engineers, and operators who care deeply about speed, autonomy, and getting the details right.
