Reference excerpt

Hello was an American technology company that sold sleep tracking devices and a sleep tracking application to help monitor sleep. The company was founded in August 2012 and shut down in June 2017.

History Hello was founded on August 28, 2012 by Thiel Fellow and CEO James Proud. A successful Kickstarter campaign from Hello in 2014 raised $2.4 million from more than 19,000 backers, making it one of the most successful Kickstarter campaigns of all time. A preliminary financing round from Silicon Valley backers raised another $10.5 million. In June 2015, the company raised $40 million in a financing round from Temasek Holdings and Hello was valued between $250 million and $300 million at the time. Other backers included Facebook Messenger chief David Marcus, Facebook's virtual reality vice president Hugo Barra, Facebook executive Dan Rose, former Twitter CEO Dick Costolo, and Spotify's head of special projects, Shakil Khan.

Sense Hello spent over a year developing a wearable sleep tracking device, but the company ultimately decided on creating a bedside device instead because Proud thought customers would be more likely to keep using the product. Hello released their sleep tracker, Sense, on February 24, 2015; 21,000 units were sold during its launch. The Sense product includes a bedside device, a "Sleep Pill" that tracks a user's sleep by clipping onto a pillow, and a sleep tracking app. Sense has sensors that track temperature, light, sound and allergen particle data and can also play sounds to help the user fall asleep. The product gives the user a sleep score every night and wakes the user up at the right point in their sleep cycle. On November 1, 2016, the firm released a voice enabled version of the Sense sleep tracker.

Shut down While trying to look for a buyer, Proud announced on June 12, 2017, in a blog post on Medium that Hello would be shutting down and the company laid off most of their employees that same day. Hello was also reportedly unable to pay its bills. The company said they were in talks with Fitbit for them to acquire the company, but failed to reach a deal. According to BBC News and Buzzfeed News, Hello shut down due to a lack of consumer demand for Sense, unenthusiastic reviews for the product, and competition from bigger brands. Although Hello shut down in June 2017, the company's website, Hello.is, remained online until January 2018.

Worked examples

Example 1 — a first encounter with Hello (company)

Start with the simplest possible case. Write down what Hello (company) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hello (company) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hello (company) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hello (company)

In research: Hello (company) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hello (company) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hello (company) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct manufacturing companies based in the San Francisco Bay Area, Electronics companies disestablished in 2017, Electronics companies established in 2012, so understanding it makes those chapters shorter.
In everyday life: Look for Hello (company) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
