Fractional ownership sells. Running it is the hard part.
ASTIN is the operating layer for property-specific co-ownership. It holds the ownership state, allocates a calendar that is worth different amounts in different weeks, records what each owner decided, attributes revenue and cost to the right share, and carries a transfer through to the point where a licensed party executes it.

The sale is the easy half
Selling a share in a villa or an apartment is a solved commercial problem. What follows is not. Four to eight owners, one calendar, one set of running costs and one eventual exit generate an administrative load that spreadsheets absorb badly and disputes expose quickly.
A calendar of unequal value
New Year in Dubai and a Tuesday in August are not the same asset. Split the year into equal night counts and you have built a dispute into the structure before the first booking.
Revenue that loses its owner
When unused weeks are let, the proceeds are usually pooled. The owner who released the week and the owner who used theirs are then treated identically, and nobody can reconstruct why.
Documentation nobody can find
Title, valuations, inspections, insurance, budgets and the co-ownership agreement live in inboxes. Every new co-owner and every exit restarts due diligence from nothing.
An exit with no process
A share sale needs a valuation, a buyer, a pre-emption step, a document pack and an authorised party to execute it. Without a defined workflow, each one is improvised.
One record per asset, five connected functions
ASTIN keeps a single operational record for each property and drives the whole life cycle from it. Change an ownership share and the calendar allocation, cost split and owner statements move with it.
Four operators, one record
ASTIN is a B2B product. The people who log in are the ones who actually run the asset — plus the co-owners they answer to.
Premium units that are slow to sell whole.
The unit becomes accessible to buyers who cannot or will not take the whole ticket, with the post-sale operating model defined before the first share is signed.
Capital tied up in an asset you still want to use.
Capital released without losing use of the asset, and an arrangement that survives disagreement because the rules were explicit before the money moved.
Divided ownership, with an operating model behind it.
A differentiated offer at the premium end, and a defined path for the resale transaction rather than an ad-hoc one.
Inventory that arrives clean.
Co-owned stock becomes as operable as single-owner stock, and month-end reconciliation stops being a manual exercise.
Exercised on a real asset, not a slide
ASTIN was run end to end in a live operating environment in Gran Canaria: a specific property, a real independent minority investor, a real co-ownership arrangement, and a share transfer that a notary completed under Spanish law. The system carried the process up to that act and recorded the result.
That exercise validated the workflow, not a commercial rollout. What remains for production deployment is set out in full.
- Asset onboarding
- Ownership structure
- Co-investor onboarding
- Calendar allocation
- Cost and revenue attribution
It is not a commercial rollout, and there is no customer. The scope was one asset, one jurisdiction and one independent counterparty.
A software business, not a launch
ASTIN is built by Profelis Consulting, a Polish software company that has been delivering engineering work for clients abroad since 2019. ASTIN is its own product rather than something licensed in and resold — which means the people who answer your questions are the people who wrote it.
- Delivering abroad since 2019
- Continuous contracted engineering, not project-by-project work.
- Luxembourg, Belgium, the United Kingdom
- Where that work has been delivered from Poland.
- Founder-led engineering
- The person who writes the software is the person you deal with.
- ASTIN is our own product
- Built and owned in-house, on the same practice that serves our clients.
Start with one asset
A first deployment does not need a portfolio. One property, one ownership structure and one season are enough to prove the operating model on your own numbers.
