Format Unlike the Turkish TV series that were broadcast in the same period, Fi was broadcast on Puhu TV, an online series platform on internet, with 60-minute uncensored episodes. Episodes of the series were published on Puhu TV's platform in 4K resolution Ultra HD and free of charge. Because the series was broadcast on the internet and there was no opportunity to advertise on the internet as it was on television, there were advertisements of some brands on many scenes of the series' episodes. Examples include a commercial for Vodafone labeled as "Vodafone Arena" in one scene, and Can Manay's decision to buy a Samsung phone after seeing an advertisement for the phone with the motto "removing the borders".

The main story of the series revolves around Can Manay, the main character, and tells the story of the transformation of all the characters over time. Writing for the media site MedyaBey, Şadan Kaba described Fi as a story centered around "Can Manay and other characters" and believed that producing the series in the format of 60-minute episodes would be an advantage as it would eliminate the risk of running out of time and material. In addition, the erotic scenes in many of the episodes of Fi were the subject of discussion on social media. Milliyets writer Sina Koloğlu wrote in his article that while broadcast on television these scenes needed to change and suggested that the production team should make two different versions for this type of scenes.

Production

Development In an interview, author of the novels series Azra Kohen talked about having met with many production companies about turning her books into a film or TV series and said that initially she did not want her books to be turned immediately into a TV series and had decided to wait for at least 5 years. However, after having a discussion with Ay Yapım she changed her mind. Ozan Güven said in a meeting in May 2017 that the project was first proposed 1.5 years ago and that the main cast had not been formed at the time but the project itself had been initiated. The author of the novels later mentioned that the novels had been written as a series of self-help books, which she did not except to be turned into a successful work at the time, and added that she had "already [written] the books with a visual perception" and therefore she had designed the storylines accordingly. The author also mentioned that the person who had changed her mined about turning the books into a TV series was in fact Pelin Diştaş, and said: "Apart from Ay Yapım, Pelin Diştaş was a quite important figure [...]". The author attended meetings held by production companies in order to recognize "different categories of people" until she came to Ay Yapım, and also added, "If it was not for this team, without the staff of Ay Yapım, there would have been no series made from these books".

When the project was announced online for the first time, it was referred to as "Fi Çi Pi" on social media, but Azra Kohen, the author of the novel series, said the series would have only one name. The official name of the series was announced by puhutv as Fi in March 2017 and the first promotional poster was published. Nükhet Bıçakçı adapted the novel series to prepare the screenplay of the television series. The first promotional video of the series was released on 10 March 2017. On 31 March 2017, the release date for the first three episodes was announced. On 25 March 2017, it was reported that telecommunication company Vodafone would sponsor the series, and it announced to its customers that they could watch Fi for 6 months without paying any internet fees.

In December 2017, author Azra Kohen appeared on Radyo Trafik Marmara's radio program Yazarın Dilinden and announced that the TV series would finish with two seasons in total. She added that she did not want the series to continue by saying that the series was planned to last 4 seasons but the second season had become deviated from the books and that the only thing remaining constant were the characters. In the interview, Azra Kohen said that in the first season "after the first three episodes the reference points had remained the same, [...], but they tell a completely different story afterwards". But the production company was planning to complete the project with two seasons from the beginning due to the lack of action in the first two books and Habertürks writer Mustafa Doğan claimed that it was the production company, not Kohen, who had decided to finish the series earlier. Kohen, in turn, said that in the contract with the production company it was mentioned that "The series cannot in any way go away from the essence of the book and its characters and cannot go beyond its meaning" and she had taken the decision to terminate the series and also wrote a book about her experiences during this process.

Casting The first choice to portray the character Can Manay was Ozan Güven since the beginning, and it was confirmed by Kohen's colleague Ebru, who stated: "We were so obsessed with Ozan Güven that we would have done anything to make him accept the role". The other two alternative choices for the role were Cem Yılmaz and Okan Bayülgen. Members of the main cast gave an interview to Vogue Türkiye which was published in April 2017. Ozan Güven stated that he had accepted the role "due to its different nature compared to the repeating monopoly of Turkish TV series".
