It provides confidential spiritual guidance, personalized devotions, biblical studies, and support for daily challenges — including mental health topics like anxiety, PTSD, and grief — from a faith-based perspective. It supports 12+ Bible translations with audio, generates personalized study plans, and adapts responses per denomination (Baptist, Pentecostal, Protestant, Catholic, non-denominational). ### The Pivot Story SoulStream started in December 2018 as Book Vitals (later Basmo), a reading tracker app. After 4.5 years without achieving product-market fit, the team integrated an "Ask Question from Any Book" AI feature. Data analysis revealed the Bible was overwhelmingly the most-asked-about book. This data-driven insight sparked the pivot to Bible Chat in 2023, which achieved explosive growth immediately. ### Technology Built by Marius **Adloops** — AI-powered marketing automation platform that automates the entire ad lifecycle across 8 ad networks (Facebook, TikTok, Snapchat, Pinterest, Apple Search Ads, AppLovin, Google Ads).

I don't want to get anywhere. I just live my life. I try every day to do what I like." - "I don't feel unhappy working 16 hours a day at the office." - "Simple. We come from a background where we know how to scale apps. It didn't catch us by surprise." - "Skills can be learned, but if you're rigid, don't accept feedback, never ask for help, and have an 'I know everything' mentality, you don't fit." ## Partnership with Laurențiu Bălașa Marius and Laurențiu Bălașa (CEO) are complementary opposites. Marius is pragmatic, non-emotional, and precision-focused — excellent for decision-making. Laurențiu is emotional, visionary, and long-term oriented.

Marius stayed through the darkest period out of loyalty and friendship. ## Social Impact - SoulStream umbrella: "AI Apps for Minimizing Human Suffering" - 90%+ of Bible Chat features remain free and unlimited - Afterschool programs in Necșești, Romania - Distributed 1,000+ meals in the Philippines - Hacker25.com — Romanian community for aspiring app developers ## Media Coverage EY Romania, Tech.eu, The Recursive, Romania Insider, HotNews, Wall Street Romania, start-up.ro, ZF.ro, Adapty case study, Business Room Podcast, Romanian Startups (YouTube).
