Why you shouldn't think twice about hiring us


Smart investment, high speed

Building a team to get a product v1 out of the door will take you much longer than hiring us. Being fast and good comes with time and we have that experience.


Pay for when you really need it

Paying for an in-house tech team if you don't need them in certain phases is a waste of resources.


React to the scarcity of professionals

People like us are hard to get. Teams like us are even harder to get and hardest to retain. Most company cultures aren't attractive for professionals like us to work for full-time.


Phase Flexibility

Products go through different phases which need different people. Hiring employees and having to let them go after a year usually isn't worth it. If you're sure you'll master your current phase with a team like us, we are your best bet.


Total Investment efficiency

A $1 spent on Bonsai is a $1 spent on a software creator. We don't have an overhead team of salespeople, managers and shareholders to compensate who only drive project costs up and deliver you no direct value.


Skin in the game

Our team size is the sweet spot for the work we do and we have full ownership of our company. What's a better indicator of your project getting the full attention and love it needs?

I’m saving tons of project management time with Bonsai, because they listen very carefully, ask the right questions upfront and have an eye to engineer excellent web applications you will only get from senior people. They’re specialized and absolutely premium when it comes to UI/UX heavy React based web apps.
