## Career
### Summly

In March 2011, D'Aloisio launched an iOS app named Trimit, which used an algorithm to condense text such as emails and blog posts into a summary of 1000, 500, or 140-character text. With 100,000 downloads, the app was featured as on the Apple App Store. Shortly afterwards, Trimit attracted the attention of business magnate Li Ka-Shing, who provided 16-year-old D'Aloisio with US$300,000 in venture capital investment. After gathering feedback, D'Aloisio re-designed the app and renamed it Summly in December 2011.
Summly aimed to solve perceived problems with the way news articles are presented on smartphones, with the initial version of Summly being downloaded by over 200,000 users. He hired a team from Israel, including a scientist named Inderjeet Mani, who specialised in natural language processing, to improve the app. With corporate support, in November 2012, D'Aloisio received US$1 million in new venture funding from celebrities such as Yoko Ono, Ashton Kutcher and Stephen Fry, in addition to Li Ka-Shing. In March 2013, D'Aloiso sold Summly to Yahoo! for approximately US$30 million, according to allthingsd.com, but price wasn't officially disclosed. He joined Yahoo! as a product manager the same month.
The Summly algorithm first decides whether a document is summarizable by using a classifier model that is trained on a dataset of summarizable documents and unsummarizable documents (such as works of fiction). Then, a scoring system is used to identity and prune uninformative and incoherent sentences until the summary drops below the word limit. The coherence score is obtained by assigning weights to the presence of features in the sentence. For short summaries, the informativeness score of a sentence is determined by language-independent features such as its position or length. For longer summaries, a support vector machine learns to detect sentences with the highest ROUGE-1 scores. For other summaries, a random walk is used to determine salient nodes in a graph (a la PageRank) where sentences are represented as nodes with exponentially decreasing weights for those that appear later.

### Yahoo News Digest

In January 2014, D'Aloisio announced the launch of Yahoo News Digest at the Consumer Electronics Show in Las Vegas. An evolution of Summly, Yahoo News Digest provides mobile users with a summary of important news of the day in the form of a twice-a-day digest. The articles are automatically and manually curated, as well as summarised into key units of information, known as "Atoms", which include maps, infographics, quotes and Wikipedia extracts. The Verge praised the app, stating, "Yahoo! News Digest is the boldest and most visually impressive app the company has released since Yahoo! Weather last year." It was the winner of the 2014 Apple Design Award. D'Aloisio resigned from Yahoo! in October 2015.

### Sphere

In late 2015, D'Aloisio co-founded a new startup called Sphere Knowledge with Tomas Halgas, who he met at Oxford. Whilst yet to be made public, Sphere is said to be knowledge-sharing service where users can swap information via instant messaging. As of March 2019, the Financial Times reports that the company has raised US$30 million. In October 2021, multiple news outlets including TechCrunch, The Telegraph, The Times and BBC reported that Sphere had been acquired by Twitter, and that the majority of the 30-person team would be joining the company.
