The 28 project holders: who you sell to

What decision this changes
thesisOur reading
What follows does not come from a source that states it: it is what we read when we cross the figures on this page. Every number behind it is above, with its confidence mark and its source.
If you are selling a service
The project list tells you where the work is. This one tells you who signs the purchase order, which is not the same thing: the RIGI holder is usually a vehicle with a different name and tax ID from the brand you know.
What to do today: before sending a proposal, check the Ownership column. For a listed company you can read the capex plan in its quarterly report and know what it is about to buy; a private one you have to ask.
If you are already in the sector
The 35 service companies below are not colour: they already hold the relationship and have set the price. Meeting them head-on in their own specialty is the most expensive way in.
What to do today: cross this list with the niches. Where a niche names no incumbent, the gap belongs to a local supplier, not to a multinational.
Which of these companies can you sell to?
Tell us what your company does and we tell you which project holders your sector fits into, who already supplies them and where it is best to get in.
Analyze my companyHow to read this, and what it does not say
Where it comes from. From the 63 records in data/empresas/, with the confidence mark and source they already carry. No figure is computed on this page: it collects and groups.
Holder or service company is decided by the sector, not by us. Same rule the province panel uses: oilfield services, steel and pipe are suppliers; everything else is a holder. A company that does both falls on the side of its declared sector.
“Listed” refers to the Argentine vehicle, not the group. Several holders are local companies that do not list even though their parent does; the column says so and the detail is in the record. An empty field is never published as “not listed”.
What it does NOT say. This is nobody’s supplier register and not the full list of companies in these provinces: these are the ones that show up in the projects in this portfolio. A company missing here is not a company that is absent.
