One car The two-ton car was about to slowly crush a small device that looked like a travel case, and the latter was connected to a mobile phone showing a charging screen. This may be a destructive experiment with evil interests. What you, who are waiting for the tragedy, never expected is that this small device was unscathed after being crushed by such an environment and still supplied power to the mobile phone. Maybe you have guessed that this gadget is actually this power bank. Your intuitive feeling is: the quality of the thing is really good.
▲Crowdfunding video screenshot, Zendure travel case series power bank undergoes stress test
This marketing video first appeared on the famous crowdfunding website Kickstarter, and the name of the power bank shown in the film is Zendure A Series. Once crowdfunded, it quickly gained support from more than 2,000 people. However, some people have questioned the authenticity of this video: a Middle Eastern tycoon once drove a luxury car over this power bank. As a result, the power bank was still hard, so he posted the video on Instagram, which attracted a lot of attention.Zendure also began to gradually become known.
Burundi Sugar Daddy The idea to create Zendure originated from Bryan Liu, a top student at Peking University and former marketing director of Halma. Bing Bin). At that time, smartphones were not very popular in the United States. The demand for power bank products was booming, and the existing products on the market actually had too many shortcomings: small power, ugly design, worrying quality and safety hazards. However, At the same time, it also reflects the valuable business opportunities in the North American variable position power supply market.
After Bryan Liu left Halma, he tried selling goods on eBay for a period of time. Later, he hooked up with his junior student Tom Haflinger, whom he met when he was an exchange student at Menlo College. The latter had just resigned from Apple, and the two were in the United States together. Silicon Valley created Zendure in 2013.
▲The two founders, Bryan Liu on the right, serves as CEO
Although the Zendure brand is registered in Silicon Valley, Brand Planet believes that its gene is an international Chinese brand. Since Zendure began to focus on the US market, the Silicon Valley headquarters was actually only responsible for marketing in the US market, with Tom Haflinger serving as marketing director. Zendure has branches in Guangzhou and Shenzhen, called Jianghai Technology, which are responsible for operations and R&D respectively. Bryan Liu is the largest shareholder.
The quality of tools is the biggest difference
The biggest differentiator of Zendure products is “sturdiness and durability”, which also explains the origin of the name Zendure: “Zen” means “Zen”, Emphasis on elegant aesthetics; “Endure” means “firm”, emphasizing the quality and durability of things. For example, the Zendure travel case series power bank mentioned below is the only product in the world that can be run over by a car without being damaged. In terms of appearance, it is simply designed as a fashionable travel case, specially built for people who travel. After all, the power bank is most useful when traveling.
▲SuperTank variable position power supply, capacity 27000 mAh
According to the user satisfaction questionnaire initiated by Zendure, the reason why consumers choose Zendure is the quality, capacity and durability of the tool. In terms of brand positioning, Zendure is oriented towards the high-end market and focuses on technology. It is between ANKER and Belkin, but it is better in design, while another competitor, mophie, is more design-oriented.
However, Zendure is not only a mobile phone power bank, but also has the ambition to be a leader in the charging industry. After the analysis of brand planet, ZendureThe selling points of certain charging products are really eye-catching: for example, 100WPD fast charging, 27,000 mAh notebook variable position power supply Supertank, which supports four devices at the same time, and the key point is that it can board an airplane; Passport global plug, that is, one plug It is applicable to 150 countries and regions around the world, and will automatically repair it when the fuse is burned out.
▲Passport pro global plug
Although Bryan Liu was born in marketing, he seems to be a bit stubborn about his products. In fact, the variable position power supply market has actually experienced an upgrade. It is increasingly difficult to achieve a single channel and cost-effectiveness. The products that survive in the end must be products with high quality and technical content. Coupled with a clear positioning and a stable domestic supply chain, Zendure said the company “has never experienced too many setbacks.”
Breakthrough: Use crowdfunding to validate the market and acquire customers
As a start-up company that has only been established for five years, Zendure has gone from being unknown to gradually opening up the market. Brand Planet believes that its breakthrough is through crowdfunding. The situation has stopped.
Zendure has streamlined its Burundins Sugardaddy product line and concentrated resources to create a competitive and even explosive product. Fundraising websites such as KickstBurundins Escortarter and Indiegogo serve as platforms for verifying minimum viable products. The five star products developed by Zendure are Use them to understand whether the product truly solves user pain points and market demand. On the other hand, crowdfunding can attract the attention of technology media and continuously increase media exposure.
▲ Some of Zendure’s crowdfunding projects on Indiegogo
Starting from the first travel case series power bank launched by Zendure in 2013, the crowdfunding amount has accumulated to US$1.66 million so far. , attracted tens of thousands of participants. These people are often early adopters. If a product with both quality and design can be recognized by them, they will often actively distribute it to friends and plant seeds to ignite word-of-mouth. And 84% of Zendure users said they would strongly recommend its products to their friends.
According to Zendure’s introduction to Brand Planet, the most loyal fan base currently originates from crowdfunding projects. As geeks, technology bloggers and avid digital enthusiasts, they are extremely demanding on electronic products and experiences. In particular, they have a lot of electronic devices that need to be charged. They need larger capacities, faster charging speeds, and more power than ordinary people. Port more products.
▲ Zendure has as many as 1 million reviews on Yutube. Many of them are in Arabic, which shows that the Middle East market is one of Zendure’s main markets.
So Zendure first targeted these core customers and met all their expectations for the product. Zendure, like OnePlus, modifies and iterates products in a timely manner based on fans’ opinions and feedback. For example, the laptop fast charger just mentioned that can be taken on board a plane was developed based on suggestions from fans.
However, Zendure also revealed to brand planet the experience gained during crowdfunding: the first wave of customers is very rare, and when crowdfunding, it is necessary to fulfill promises and pay attention to building trust with customers. At that time, I lacked experience in the first crowdfunding, and I promised to upgrade the battery cells after raising US$200,000. However, due to the wrong cost budget, you will lose a lot of profits if you upgrade, and you will lose your reputation if you don’t upgrade. In the end, Zendure fulfilled its promise and guaranteed the consumer experience.
In the United States, there are many DTC brands that have been launched through crowdfunding. For example, the multi-functional travel jacket BauBax raised US$5.6 million on Kickstarter for the first time, becoming one of Kickstarter’s most popular crowdfunding projects. However, the first crowdfunding could not be delivered in time due to production capacity issues, so BauBax chose shipping. Although the cost increased by 4 times, it gained the trust of the first wave of customers. The subsequently released BauBax 2.0 raised US$10 million in crowdfunding.
Let’s talk about a few more successful crowdfunding projects:
The first product, the A series, as the most stress-resistant variable position power supply, raised more than 200,000 US dollars on Kickstarter;
Zendure Passport International The travel socket raised more than 300,000 US dollars on Kickstarter and won the Good Design design award;
ZenBI Escortsdure Supertank notebook modification Location Power has raised over $1 million in crowdfunding across the internet.
From crowdfunding to Amazon, offline channels are equally important
In addition to obtaining funds for each new product through crowdfunding, Zendure has chosen Amazon as an important channel since April 2014, selling directly to European and American consumers. who. Brand Planet also discovered that Zendure quickly established an online mall using Shopify, a website building tool commonly used by European and American DTCs, and its plug-ins, improving the international payment system, forums, SEO optimization, promotion and other functions.
As mentioned earlier, Zendure believes that location-changing charging equipment cannot rely entirely on online or a single platform.Zendure has now expanded online channels including Amazon in the United States, Europe, and the Middle East. In order to meet the needs of actual application scenarios, offline markets such as shopping malls and airports have also begun to be deployed. Zendure has also opened flagship stores on Tmall and JD.com. The sales performance on JD.com is better. After all, it has only been sold for less than 3 months since the crowdfunding in April 2019.
▲ Zendure’s sales on JD.com
Burundi Sugar After 6 years of accumulation , Zendure has achieved a 1% share of the global market and is expected to usher in a growth spurt in 2019, with sales tripling compared to previous years. However, Zendure also admitted that there will be no doubling in the future, but there may be a growth rate of about 50%. It is worth mentioning that due to good growth and solid cash flow, Zendure has not stopped any financing. Zendure also expressed to Brand Planet that there is a possibility of mutual cooperation if the values are different for the venture capital structure.
Brand Planet Summary
First, the changing position of the power supply and electronic accessories market can be said to be the breakthrough for Chinese brands to go overseas. We can see many excellent brands such as ANKER and AUKEY appearing online in the United States. The market may be smart equipment, smart homes, or even fashion and fast-moving consumer goods in the future, relying on China’s increasingly perfect supply chain and R&D. (By the way, Belkin has been acquired by Hon Hai Group in 2018)
Second, for this category, the key to successful brand shaping is to establish trust and Burundi Sugar DaddyThe application experience exceeds expectations. Trust is built on the quality of things. However, any brand can use the quality of things as a selling point, and the brand needs to clearly and intuitively display the selling point through active communication. Secondly, human beings are lazy and always hope to solve all problems with a button. The emergence of technology products is to help consumers easily solve various unpleasant problems in application scenarios.
Third, crowdfunding is a good way to verify the market, acquire loyal customers, and achieve word-of-mouth communication, especially for technological products, if they have some screaming performance. BRANDSTAR
