Makezu is an app that helps bootstrapped startups, entrepreneurs, and small businesses send personalized messages to target customers on Twitter. Hélène Lucien, the co-founder and CEO, met her partner Anne-Sophie de Gabriac while running another startup, and neither of them has a development background. They used no-code tools like Bubble to build Makezu quickly, which took 6 weeks to develop. The app finds potential customers on Twitter based on keywords or major life events and sends personalized messages when they express interest in the product. With Makezu, businesses can track campaign metrics such as message sent, clicks obtained, and social profiles reached. Hélène discovered no-code tools like Bubble while running another startup and was looking for solutions to set up marketing operations without recruiting developers. She chose Bubble because it enabled her to create a product quickly and test the idea before deciding whether to continue building. Makezu has gained traction with 110 beta testers, sending over 1336 messages with an average click rate of 8%-38%. The company plans to improve user experience, expand value propositions, and connect Makezu to other social networks and advertising platforms.
