Our Values

Be persistent

What we aim to do is not always going to be easy, and problem-solving, no matter how big or small, is essential if we are going to achieve our mission. Whether it be a technical challenge you are struggling to unblock, a new client you are trying to win or a logistical puzzle you need to solve, the only way we will grow as a company and as individuals is by persistently working things through to a solution. Success seldom comes from the first attempt, but it almost always comes from the 1000th, and the difference between success and failure often isnt intelligence or the aha moment or the brilliant idea: its having the perseverance to continue pushing and never giving in to failure.

Be accountable

We operate in a fast-paced, highly collaborative and increasingly autonomous environment at Hypervolt. We are on the journey from a scrappy startup to a market leader, but no matter how big the company gets, treat it as your own. Be accountable for its progress, and look after it as you would your creation. If you know things can be improved, articulate it, say it, and dont go along in the silence of knowing we could have done better. If we make a mistake, find a way to say it. Theres no value in keeping it to yourself; we will succeed or fail together.

The Ello Sir Ethos

We should always strive to treat people how they wish to be treated and remember the voting power of customers. They are the true bosses and the actual employersthe market.

Dare to dream

Every technological advancement we use today was once a crazy dream that a few persistent pioneers truly believed. Most things have to be seen to be believed, but some things have to be believed to be seen! Steve Jobs, on building the Apple Mac, the best-selling computer of all time.

Stay hungry; stay foolish.

The hunger and ambition for continuous success are the orbital solar beam-powered reactor at the core of our success, and our ability to stay foolish and humble and continue to let ourselves be educated by our market will help us reach the full potential of our ambition. Only through the most selfless dedication to our dreams will we achieve the most selfish successes.

True Greatness is Blind

Great ideas and execution can come from anyone and anywhere at any time.
