Client Success Stories
Idea Maker has done an amazing job of delivering and responding to our needs.
The team was very responsive and easy to work with. They are professional, talented, and experienced team. They were able to meet all our requirements.
Idea Maker is distinguished for their personalized collaboration and white glove services. The team is dependable and reliable, sticking to the project's plan, offering feedback, and pushing back on the right things.
The way they understand the requirements we present to them is fairly solid. Both in terms of bringing their own interpretation in nailing the requirements and their design sense. By the time we launched, I had gotten significantly more value from our collaboration than what we had discussed in the original specs.
This is a boutique development firm where the Founder is directly involved with the project and the primary contact. This is unlike many development firms where you are simply handed off to developers that are not stakeholders. This is an important distinction that results in much better project accountability.
I have never had a site like this built before. I felt that Idea Maker and Tom had built numerous sites like this, and they were pros.
Idea Maker's portfolio is what drew us in. Their design style was in alignment with what we were after. We had initial consultations with 3 companies that we had narrowed it down to. Once we had our initial meeting with Tom at Idea Maker we knew we had the right choice to make. Their communication style works well for us.
Their customer service is excellent — they’re incredibly accessible and available, which I appreciate. Furthermore, they have enough experience and bandwidth to fulfill all my needs. They’re one of the best vendors I’ve worked with.
