About us

Innovation is fuelled by the power of possibilities. A few years ago, it was virtually impossible to innovate because building software needed a degree, it was simply too expensive, too complex, too risky and ultimately too inefficient. That’s why only 16% of projects were ever done on budget and 78% failed.

We're changing that. We’re flipping software development on its head and kicking out the notion that you need to be an expert or do boot camps to learn how to make your app.’s platform lets you order the perfect software app for whatever problem you’re trying to solve. Our AI-powered assembly line brings together Lego-like reusable features and experts from around the world to bring world-class ideas to life – ANYONE’s world-class ideas.

Building software needs to be like ordering pizza – pick what you want, get recommendations for the features you need and simply wait till it's cooked and ready for you.

Our human-assisted AI platform helps anyone build, run & scale tailor-made software. Everyone from the bakery in Riyadh and nursery in London, to large fortune 100 companies like the BBC or Pepsi.


Life at Builder

It’s a place where everything moves at lightning pace and most definitely not for the faint-hearted. We celebrate diversity, push everyone to do more with less and yet provide a culture that allows everyone to experiment, push boundaries and learn by doing. Every Builder runs to our core value system of HEARTT (Heart, Entrepreneurship, Accountability, Respect, Trust & Transparency) and we’re always looking for team players, with a point of view, a sense of humility and a let’s-get-stuff-done attitude.

Our scale-up is at the intersection of a quirky startup where designers and machine learning specialists work on problems together to savvy commercial teams working with finance folks to invent new business models. #WhatWouldYouBuild

We are looking for a versatile & out of the box innovator who will be at the forefront of cutting-edge AI technology that is disrupting a combined $800 billion (and growing) industry for software build and operate services, selling into both the B2C and B2B markets.
