Consumer edtech / non-fiction book summaries

Blinkist

The founders cut non-fiction books down to fifteen-minute 'Blinks' that could be read or heard on a commute.

For about two years after Blinkist 1.0 launched in 2012, the product that later reached millions of readers was barely holding on. Blinkist's own account is blunt about it: money was short, downloads were low, the product had problems, and nobody knew how to reach the right people. The four founders, who had been friends since university, kept going anyway.

The idea came from a habit, not a market study. Sebastian Klein has recalled taking notes while reading non-fiction books at university. Together with Holger Seim, Tobias Balling and Niklas Jansen he turned that habit into a company on August 21, 2012. A podcast fragment even hints at an earlier, vaguer name, but it is too garbled to rely on, and the founders' own telling is that they began with a broad idea about learning before they narrowed it.

A consumer subscription for non-fiction summaries is a pleasant business, but hard to turn into a giant one.

That narrowing was the hard part. The first version did not click. Users downloaded, looked, and left. What the founders needed was a format that fit a life with no free time. They landed on the 'Blink': a book boiled down to fifteen minutes that could be read or heard on the way to work.

It worked slowly and then quickly. After the public launch in 2013 the product grew into a catalogue of more than 6,500 titles, available in English, German and Spanish. In 2018 Insight Venture Partners led an $18.8m round, and the company counted about $35m in assets that year. Earlier backers included Greycroft, Headline, IBB and MGO.

The price of success was a narrowing of ambition. A consumer subscription for non-fiction summaries is a pleasant business, but hard to turn into a giant one. In May 2023 the Australian edtech company Go1 acquired Blinkist, a deal reportedly driven by demand from employers who wanted learning content for their staff. The investors joined Go1's shareholder list.

The company's story is told in public by its founders, and little of it concerns family or childhood. What the record shows is stubbornness. Two years of poor numbers, and still a team that stayed together.

The lesson for first-time founders is the one the founders gave themselves: the format that works is rarely the first one you build. The business only appeared after they stopped explaining books and started respecting their readers' time.
