What ISI Tech Consulting is

We are an IT consultancy with over seven years of work and more than 1,000 systems managed.

Why it exists

ISI Tech Consulting exists because of what traditional consultancies get wrong: no transparency, no straight answers, bureaucracy and rounds that end in nothing. The four facts below can be checked on this site, without picking up the phone.

We publish who we are not a fit for

All eight service pages carry a column on the client who does not fit, and none of them is boilerplate.

We document as we work

We do not document at the end, when nobody remembers why each decision was made. What we hand over can be maintained afterwards without depending on us.

The assessment is paid work

Nobody can price what they have not inventoried. Charging for the short assessment phase is what makes the figure stand up, instead of one corrected halfway through.

Asking is not billed

We always answer, and a call to ask something does not appear on a line item later. What gets billed is the work done.

Who we work with

We work with businesses, individuals, associations and public administrations, across Spain and with clients in any country. What decides whether it is solved remotely or somebody has to go and look is the problem, not the distance.

Where the documented work is

One sector for each documented case.

Who we turn away

Anyone arriving with undocumented infrastructure or software who wants a fixed quote the same day: the job ends in more hours than billed. Anyone who only looks at the price, because the next step is cutting what holds the work up. Anyone who wants the fire put out without letting us see what started it, because the cause remains.
