What happens after I get in touch?
Someone who works in the area you asked about will come back to you within 3 working days to arrange a first conversation. That conversation is about understanding the problem, so nobody will send you a proposal before they have listened.
Do I need a detailed brief before contacting you?
No. Most of our engagements start with a symptom rather than a specification: a report nobody trusts, a platform nobody fully uses, a deadline that will not move. Describe what is going wrong and we will help work out what it needs.
Is the first conversation free?
Yes. It carries no charge and no commitment, and it is where we tell you honestly whether we think we are the right people to help.
Can we sign a confidentiality agreement before sharing details?
Yes. Much of our work is covered by confidentiality agreements, and we are used to signing one before a client shares anything sensitive.
How quickly can you start?
That depends on the work and on who is available. We would rather give you a realistic start date than an optimistic one, so we confirm availability in the first conversation rather than promising it beforehand.
How do you price your work?
Pricing follows the shape of the work and the seniority it needs, so we agree it against a defined scope rather than quoting from a rate card. Once we understand the problem, you get a written proposal setting out exactly what is included.
Where are you based, and which languages do you work in?
Our teams are based in Zagreb and the United Kingdom, and we work with clients in several European countries, on site or remotely depending on what the work needs. We work in English and Croatian.
I would like to work at Koios. Where should I go?
Our careers page lists current openings. Please apply there rather than through this form, so your application reaches the right people.
