Good contact is key, so during the project we will be in regular contact with you, i.e. the person who is responsible for product development (Product Owner). Usually this is the CEO, CTO, marketing manager, etc. On our side, the first line of contact is the Project Manager, who manages the project and has control over all processes. He is the one you can address your questions to, and if necessary, he will arrange a meeting with the development team or redirect to a team member.
