A studio MVP isn't "the cheap version of the product." It's the smallest piece that a stranger can actually finish—built by a studio with a written scope, a fixed price, a deadline, and someone on the other end when it fails on Monday.
That's the definition. It's not the entire product in miniature. It's not a deck prototype to show off and then put away. It's not the team's tool of the month disguised as a product. And it's not a marketing landing page with a form.
This page defines. The decision guide — when to do and when not to — is in When does an MVP make sense?. The boundary with the internal tool is at MVP or internal tool. The commission lives in MVP for startups, within the same custom software. Wallion does not open a root URL /mvp For ranking: the module hangs from the hub.
The short answer
An outside user. Customer, shop, workshop, buyer. Not the team. If it's only used by people at home, it's not an MVP—it's almost always a internal tool.
One action. It fits in one sentence. “Reserve.” “Request a quote.” “Upload the report.” If the sentence includes “and also,” it’s still not the minimum.
A sign written before construction. He came back, paid, and asked for the next piece even though you wouldn't sell it to him. You've used no judgment, you've just handed over code.
A studio that is closing. Scope, price, weeks, owner of the "fact". Not a "let's see". Not a Proof of Concept that nobody touches the week it's released.
If that line can't be written — “A [stranger] does [an action] and I see [a sign]” — don't ask for an MVP. Ask for help figuring out the scope, or wait. If the line is from the team and from day 28, read the internal tool page, not this one.
What it is / what it is not
What is it. A minimal product with real users, built as a custom software commission: painful trimming out, a flow that a stranger can complete, and criteria written before the first line of code.
“Studio-based” matters. It’s not no-code without an owner. It’s not a freelancer who disappears when payment fails. It’s a studio (Wallion, Barcelona) that defines the scope, sets a budget, delivers in weeks, and is left on the other side if it doesn’t start on Monday—under the license model published in the offer.
What it is not.
- It's not a prototype. A Figma or a deck that's shown off and then put away learns nothing. If nobody touches it the week it's released, it's just product hype.
- It is not an internal tool. The company's month is not a market. Replacing the sheet for closing is another task, another band, another criterion. Guide: MVP or internal tool.
- It is not the complete product. Dream panel, five integrations, app on three platforms: that's it after, If the first one is used. If the cut doesn't hurt, you didn't cut.
- It's not a marketing landing page. A page with a CTA is not a minimum product. An MVP lets the stranger I finished an action.
- It is not Mobility, Glowapp or Nummo. These are not Wallion products from this service.
How it looks at a small business table (Barcelona / Spain)
There's no need for a case study with a logo. The pattern is the table: a founder who still closes sales manually, someone from operations with a WhatsApp message that's "almost the product itself," and sometimes a partner (consulting, ERP, A3-type stack) quoting the next module when the Excel spreadsheet or chat can't handle it anymore.
In Barcelona, the metropolitan area, and the rest of Spain, that same group of people often asks for the same thing, albeit in different words: “an MVP.” Sometimes the need is real—an external buyer, a clear action plan, someone who will test it the week it launches. Sometimes it's “we need to digitize” without any clear scope, or “a product for the team” that isn't a target market. Wallion frequently speaks with this type of client: a limited external investment, a thorough assessment before development, and a fixed price in writing. No fabricated clients or volumes. The standard is the group itself.
If the "user" is Maria from administration and the criterion is "to close out the month," then you're not dealing with an MVP. If the user is a business, a workshop, or a customer who doesn't get paid by you, and the signal is that they'll return or pay, then yes, you are.
When it makes sense vs. when it doesn't
That makes sense. when there's a bet that might fail soon; the scope fits in one sentence; someone from outside will use it the week it comes out; and you can write what No Enter the meeting without fighting.
It doesn't make sense. When you want to replace the entire month (tool, or several projects); when you can't say what's left out; when nobody is going to touch it; when the "MVP" is a product backlog disguised as a minimum; or when you need reinforcement/staffing and you call it a product — say so, don't hide it.
The long guide lives in When does an MVP make sense?. This one defines; that one decides.
What does “done” mean?”
“Done” doesn’t mean “we liked it in the demo.” It means: a stranger completes the action from start to finish the week it comes out — without the founder acting as glue via WhatsApp.
At a minimum: a usable safe path; data you can read later (who, when, if they returned or paid); a written sign before to build; a lock owner in the studio; someone on the other end when it fails — not a zip and a “good luck”.
If the stranger can't finish without calling, you haven't delivered an MVP. You've delivered a draft with hosting.
Public prices (Option D — without inventing other figures)
Only the figures from the site. The €6,900–€14,900 price range is not the price of an MVP.
- Diagnosis — €1,900. Written scope, prototype, fixed budget. If you continue, it will be deducted from the construction cost.
- Construction — €6,900–€14,900. An internal tool / a flow after the diagnosis. It's not the price of a large app, an MVP, or staffing.
- Building an MVP: price fixed in writing after the Diagnosis — same model (scope + number + date), another figure, not that band.
- License — from €390/month if Wallion maintains what has been built (hosting, security, regulatory and API changes, small change cap, support during business hours — depending on the offer).
Apps, MVPs, and staffing: Diagnostic → fixed written → optional license. Do not confuse the tool number with the minimum product number. Offer: MVP for startups. Hub: custom software.
Failure modes
“MVP” = cheap product. You asked for five screens, three platforms, and the dream panel, "but at the bare minimum." The compromise doesn't hurt. It wasn't an MVP: it was a product that wasn't a priority.
Eternal PoC. There's a prototype. It's taught. It's stored away. Nobody touches it. You learn nothing.
Tool with product name. Only the team uses it. You measure the month. You call it an MVP because it sounds like a startup. Poorly named—and poorly budgeted if you're comparing the wrong band.
Signal invented after the fact. You build first. Then, "Did they like it?" Without prior written criteria, the MVP award only serves to confirm that you've built something.
Staff in disguise. Live backlog, you need hands, you're asking for "an MVP." Say it. Don't mix tables.
Compare with Mobility, Glowapp or Nummo. They are not this service.
What Wallion does (and when not to buy it)
Wallion builds MVPs within custom software, to price fixed in writing After the initial assessment (€1,900, discountable if you continue). Building the MVP does not use the internal tool's public bandwidth. License, if we maintain the built version: from €390/month.
Model, in one sentence: a stranger, an action, a written sign; painful reach; closed number; date of “done”; someone on the other end when it fails.
Don't buy an MVP with Wallion when the user is only the team; when you can't write what doesn't fit; when nobody will touch it the week it comes out; when you want to replace the whole month; or when you need staffing and you call it a product.
If you say "this is a tool, not an MVP" on the call, it should be said in the first conversation. Geo: /software/barcelona.
Decision list (before ordering)
Mark each point. If any are left blank, do not sign "MVP".
- Is there a stranger — or just the team?
- Can the action fit into a sentence without "and also"?
- Is the sign (returned / paid / ordered the next one) written before to build?
- Will anyone from outside the company use it the week it's released — not just members?
- Can you list what No Come in without fighting?
- Are you measuring external usage, or the month-end closing? (If it's the month → tool.)
- Are you comparing the €6,900–€14,900 range (tool) or a fixed written MVP?
- Are you asking for a diagnostic with a range phrase, or a pilot without an owner?
- Do you need minimum product or hands in a backlog (staffing)?
- Is the "fact" that a stranger finishes the flow — or that you like the demo?
Without those answers, “MVP” is an adjective, not a mandate.
Questions that buyers do ask
Is it the same as an "agile" startup MVP?
Share the minimum requirements with real users. Change the project description: written scope, fixed price, deadline, responsible studio. It's not an endless sprint with no one responsible for closing the deal.
When is he not an MVP?
When only the team uses it, nobody touches it, or you can't say what's left out. Guides: when it makes sense, MVP or internal tool.
Does the €6,900–€14,900 price range cover the MVP?
No. That band is an internal tool/flow. The MVP is going to price fixed in writing.
Is the €1,900 diagnostic lost if we don't continue?
If you continue, the price is discounted. If not, you've paid for a diagnostic with a prototype and a written contract—not an empty deck.
What does the license include starting from €390/month?
The offer includes: hosting, security, regulatory and API updates, a limit on minor changes, and support during business hours. Major changes: fixed timeframe.
