Venture Building
Building companies from a thesis, not from a brief.
We originate, validate and build ventures - our own and, selectively, with corporate and founder partners. The discipline is the same either way: prove the demand before building the company around it.
The model
How does the venture-building model work?
A venture starts as a thesis about a market, not as an idea for a product. We look for a problem that is real, expensive and structurally unsolved, usually because a technology has only recently made a solution possible.
From there the work is sequential and each stage has a kill condition. We research the market, validate the concept with the people who would pay for it, build the smallest product that tests the core assumption, and only then build the company around what survived.
Ventures are built inside the platform, with specialist partners and operators brought in for what each stage requires. Where a corporate or founder partner is involved, ownership and the operating structure are agreed before the build begins - not after it works.
What we do and do not do
We do the origination, research, validation, product definition, brand, partnerships, go-to-market, fundraising preparation and early ecosystem building. That is where our judgement and network are worth something.
Deep technical engineering is delivered through specialist partners. We are explicit about that rather than implying an in-house engineering team we do not have.
What we do
The venture-building work.
Identify opportunities
Thesis development from market structure, regulatory change, technology shifts and the problems we keep encountering in advisory work.
Research markets
Demand, incumbents, substitutes, economics, regulatory posture and the specific reason the problem is unsolved today.
Validate concepts
Structured conversations with the people who would buy, use, distribute or regulate it - designed to disconfirm, not to confirm.
Build MVPs
The smallest product that tests the core assumption, built with specialist technical partners and scoped to produce a decision.
Develop go-to-market
Positioning, first customer segment, proof, pricing, channels and the commercial motion that gets to first revenue.
Create partnerships
The distribution, infrastructure and credibility partnerships that early ventures need before they can generate them alone.
Test product-market fit
Real usage, real retention and real willingness to pay, measured against what was predicted rather than against ambition.
Support fundraising preparation
Narrative, materials, metrics discipline and investor readiness. We prepare ventures to raise; we do not act as a placement agent.
Build early ecosystems
The first community of users, partners, advisors and advocates - the layer that makes a venture credible before its numbers can.
Stages
Each stage can end the venture.
Thesis and validation
Market research and structured validation against a written set of assumptions. Most theses stop here, which is the point.
Build and test
MVP, first users, partnerships and pricing. We are testing whether anyone changes their behaviour, not whether the product works.
Company and market
Operating model, go-to-market, ecosystem, fundraising preparation and the structure the venture needs to stand on its own.
Kill conditions are written before each stage starts. A venture that stops at validation has done its job cheaply.

Ways to work together
Three ways ventures get built here.
Own ventures
Originated, funded and built inside the platform, from thesis through to market.
Corporate venture building
Building a new venture with a corporate partner, where the opportunity sits outside the core business but depends on its assets.
Founder collaboration
Working with a founding team on validation, go-to-market, partnerships and fundraising readiness, with terms agreed up front.
Common questions
Venture building here.
Is Subirachs Ventures an investor?
No. Subirachs Ventures builds and operates ventures rather than investing in third-party companies. Fundraising support is preparation - narrative, materials and investor readiness - not capital, and not placement.
Do you build ventures with corporate partners?
Yes, selectively. Corporate venture building works when the opportunity depends on assets the corporate already has - distribution, data, licences, customer relationships - but sits outside what the core business can pursue. Ownership, governance and the operating structure are agreed before the build starts.
Do you build the technology yourselves?
Product definition, architecture decisions and delivery management sit with us. The engineering is delivered by specialist technical partners selected for each venture. We are deliberate about not claiming in-house engineering depth we do not have.
What happens if a venture does not work?
It stops. Every stage has written kill conditions agreed before it begins, and stopping at validation is a successful outcome for that stage - it is the cheapest possible answer to an expensive question.
Have a thesis, an asset or an opportunity?
If there is a market problem you keep running into, that is usually the right place to start the conversation.
