No challenge is too big or too small for our monkeys. Whether you are a small start-up, or a large firm, we offer solutions such as complete web-based services, web-based components, integrations, customization projects as well as web consultancy.

Our development process is both iterative and quick. We deliver on our promise to provide excellent service through our agile development model that remains client-focused at all stages of any given project. We ensure the quality of our work by working closely together with our customers — offering them our support around the clock. Nothing is more rewarding than working with the Monkeys.

Rules of the Jungle

We might be monkeys but we don’t deliver crap. Fast Monkeys is specialized in delivering superbly reliable, sexy, functional web services that work like magic. We ensure the quality of our work by working closely together with our customers — offering them our support around the clock. Nothing is more rewarding than working with the Monkeys.

Close to Customers

We work with you, not only for you. Our way of working is customer-centric, modern and flexible. We like to spend time close to our customers in order to develop a solution that is exactly what the customer wishes. We also work in your premises when needed.

Quality Assurance

We ensure the quality of our work by extensive testing that is written before the actual implementation of the code. This makes our projects run extremely reliable on any given moment. Spare yourself from the stressful and pointless bugs and maintenance costs.

Metrics-Driven Development

Doesn't matter how great of a web product you own, you still need customers to make it a success. We believe that metrics are the key in solving the bottlenecks in your customer acquisition, allowing you to continue to develop your product even after our delivery. Let the monkeys measure it and see the mounting results yourself.

Quick Iteration Cycles

Each of our project starts with setting up a test environment which is accessible for the client. The test environment is updated a minimum of once a week, which is why you always know exactly what’s going on. This way we understand your changing needs and can update the requirements on the go - as the vision grows clearer for both of us.


We take security very seriously. We take it in our hearts to protect our customers data and constantly look for ways to make things even more bulletproof. For our servers we use only one of the safest and most durable providers available - Heroku.
