Blok is using AI personas to simulate real-world app usage

Self -powered coding tools such as the indicator, re -code and Lovable developers help those developers to write many code lines every day to charge products faster. However, applications makers still rely on charging full beta versions of their applications or using simulation programs to measure how the upcoming features work.

BLOK, a ghost company, allows developers to use artificial intelligence to simulate different user characters to test the application features and learn how to improve their applications.

The company was founded by Tom Sharman and Olivia Higgs in 2024. Both were a serial entrepreneur and worked on emerging companies together in areas including travel and learning.

To date, the startup company raised $ 7.5 million over two rounds. The seed round of $ 5 million remained by Mac Venture Capital, with the participation of people working in Discord, Google, Meta, Apple, Snapchat and Pinterest. The pre -seed Blok tour with the protagonist with the participation of Rackhouse, the Ryan Hoover’s Weekend, and empty projects.

“Blok is often compared to OTPTIMIZly, but these tools are more interactive. He said that Blok takes them out by providing a predictive layer of testing for applications.

“We have supported BLOK because we believe that the development of products at a turning point. The team is shipped faster than ever, but they are still making important decisions based on A/B tests and intestinal instinct.

Higz said that the need for the test increases with the increasing complexity of the facades over time. I stated that they met more than 100 productive engineers to understand the problems facing the product teams.

“There is a real need to increase the test because the visual interface bar is increasing. We see people interact with technology through chat, so if you provide the visual user interface [elements] In this mix, you should make sure that you do not provide unnecessary friction in the user’s workflow. “

Sharman said that large and small companies face various problems. Although small companies do not have groups to test their products and get live notes, large companies want to avoid filling features in their applications and make them rational.

He said: “We are trying to reach a place where companies do not need to issue their advantages on an experimental basis and wait a few weeks or months until the results appear.”

When the customer begins working with Blok, they download their amplituds, MixPanel or Segment. Blok then performs behavioral modeling and creates different user characters for applications to test them. These people will cover almost most of the application users.

Next, the development team provides a design design and experience details – including the hypothesis they want to test and the goal of the user they want to achieve – to Blok, the user’s personal agents and then try to run the simulation several times. In the end, Blok will show visions on how users use a specific feature and make recommendations.

These ideas include a comprehensive report on experience and details about what happened well and what can be improved. The difference can also consider report and suggestions from wisdom. In addition, since 2025, there is Chatbot you can request inquiries about your experience.

BLOK has placed its product behind a waiting list and works with a preliminary group of customers, and develops largely in financing and health care. Startups said that these areas are ideal for targeting because they cannot experience bad experiences in public places and play with the product a lot.

The startup of the companies is paid through the Saas model, but it also gets to know how to balance the account costs. The company aims to reach millions of mid -number numbers this year and open up to more customers.
