Projects

Questions?

How do I get started working with Flexum?
The first step is to get in touch and jump on an intro call with our founders Myron and Anton. Typically, we’ll start a 1-2 day spike to design or build something small, but meaningful, to make sure we’re a good fit for each other.
What makes Flexum different?
Flexum is a boutique product agency that’s laser-focused on helping entrepreneurs and intrapreneurs build winning products. We do so with a design-led process, transparent pricing, and a drive to add value from day one. At core, we’re entrepreneurs like you and know what it takes to build differentiated products and find product/market fit.
How are projects managed?
Every customer has a dedicated contact person and the founders are also always involved. We’re a boutique agency so you get a lot of personal attention. We use a variety of products to help manage progress and knowledge, but we’re not religious about the choice of tools. We’re happy to adapt to your preferences, but will suggest a few of our defaults at the outset.
How quickly can I scale a team?
It depends. We always have capacity to onboard new clients and extend teams. If you’re looking to get started, build great products and step on the gas when we find product/market fit, then we’re the right fit. However, if you need to build a team of 3 designers and 12 engineers yesterday, we can help, but it’ll take time.
