Power-storage startup raises $4.75 million, after five years of very deliberate bootstrapping

Brisbane startup RedEarth Energy Storage has secured $4.75 million in Series A funding, as it ramps up manufacturing of its all-Australian power-storage solution.

The funding comes from Aussie institutional and family-office investors, and is matched by the Queensland Business Development Fund.

RedEarth was founded in 2013 by Charles Walker and Chris Winter, who previously co-founded battery storage manufacturer Redflow.

The pair built the startup to produce a full energy storage solution tailored to Aussie customers and Aussie conditions.

Most competition in the space try to apply products designed in the US or Europe in the Australian markets, and just โ€œmarket their way around the drawbacksโ€, Walker tells StartupSmart.

โ€œBut Australia is the leading energy storage market in the whole world โ€ฆ itโ€™s a very, very big market, and itโ€™s here to stay, itโ€™s not a fad,โ€ he adds.

Electricity is โ€œthe last great piece of infrastructure to properly moderniseโ€, Walker explains.

Developing a battery is extremely expensive and time-consuming, he says.

So, developing the battery itself was not where RedEarth would be able to add value.

โ€œMaking the system and designing the system here is where you can add value,โ€ the co-founder says.

Walker compares the manufacturing of the system to building a Formula One car.

โ€œYou can pick from all the available technologies,โ€ he explains.

The startup strives to create a system that works for Aussies, and then uses data analysis to keep an eye on that system for the duration of its life. It means RedEarth can let customers know when their system needs servicing, rather than the other way around.

โ€œIf youโ€™re a manufacturer these days you have to keep an eye on what youโ€™re manufacturing โ€” especially if itโ€™s technical โ€” and monitor and use data effectively,โ€ Walker says.

Timing it right

Although RedEarth has been up and running for some six years now, this is the first external funding the startup has received.

The founders made the decision to bootstrap for as long as possible following Winterโ€™s experience at Redflow, where โ€œhe got very dilutedโ€, Walker explains.

โ€œWe decided we would make a company that would make a profit, and we would focus on keeping as much of it to ourselves.โ€

So far, the co-founders havenโ€™t taken a salary, and have invested all of the startupโ€™s revenue back into the business.

Now, theyโ€™ve got to a point where they have products they know they can sell, and some satisfied customers too.

โ€œHappily, thatโ€™s the point to raise money,โ€ Walker says.

โ€œThe reality is, we wanted to prevent as much dilution as possible. But in the end, you just need a volume of money that you canโ€™t produce yourself.โ€

While he admits he and Winter might have had an easier time if they had taken on investment, they were determined to hold on to as much equity as possible, โ€œby absorbing that painโ€, he says.

He also notes the startup benefited from being independent, and somewhat under the radar, as it was iterating and failing.

โ€œWe tried and tested a lot of products during that time,โ€ he says.

If youโ€™re a high-profile startup that has a high-profile failure, โ€œit doesnโ€™t matter if itโ€™s part of the normal engineering process, itโ€™s still a failureโ€.

Itโ€™s going to happen

Now it has almost $5 million of cash on hand, Walker says RedEarth will be โ€œreally coming out of the shadowsโ€.

Already, itโ€™s invested in two new production lines, a new premises and boots on the ground selling the products. Itโ€™s also working on certification of its systems, and establishing fleet management capabilities.

Now, itโ€™s looking to hit new milestones, and to launch โ€œa new product or twoโ€.

Looking to the future, Walker and Winter are working towards creating a community of RedEarth users that can โ€œtrade electricityโ€.

Such a system would allow people who generate their own power to sell any surplus to others in the community, or on the open market.

โ€œThatโ€™s the big product,โ€ Walker says.

โ€œWeโ€™re not there yet.โ€

The co-founders see Australia moving further towards renewable energy solutions.

โ€œAustralia is massive, the population is tiny,โ€ Walker says.

Currently, power travels from a power station, through a very long wire, to power individual homes or areas.

Previously, that electricity would power a lightbulb or two. Now, it has to power air conditioning systems and charge electric vehicles.

โ€œPeople can make and use their own electricity these days, so that is part of the solution,โ€ Walker explains.

โ€œItโ€™s just one of those technologies that is going to happen.โ€

โ€œEveryone can do itโ€

When it comes to running a startup, Walker advises other founders to trust their own judgement. It can be easy for entrepreneurs to get sucked into an idea of how their startup should be run.

โ€œSubconsciously theyโ€™re reticent, because they see other companies doing certain things in a particular way,โ€ he says.

But every startup, and every founder, is different. You donโ€™t have to take the same route as the high-profile, headline-making tech companies.

โ€œUse your intelligence, work it out,โ€ Walker adds.

โ€œYou can do it โ€” everyone can do it.โ€

For Walker and Winter, this was particularly pertinent when it came to financing RedEarth. Several VCs encouraged the founders to take on investment earlier, Walker says.

โ€œYou canโ€™t lecture someone on anti-dilution if youโ€™re doing the diluting,โ€ he notes.

He urges founders to think about the long game, and consider how much of their venture they would like to own once itโ€™s turning a profit.

โ€œWith a VC, you can end up owning very little.โ€

If someone is telling you not to worry about dilution, โ€œif thatโ€™s coming from a diluter, then you have to ignore what theyโ€™re sayingโ€, he warns.

โ€œIf you just do a bit of thinking about it, you can put a plan together and you can achieve it.โ€
