We are a website that lists every repertory, independent, and specialty movie screening happening in Los Angeles. Film fans come to Revival Hub to discover unique movie-going experiences: a Q&A screening with their favorite director, a rooftop screening of a nostalgic 80s movie, an all-night horror movie marathon, or even a 16mm silent film screening at a historic theater. We currently have over 12,000 monthly unique visitors, 5200+ Instagram followers, and 1200+ email subscribers, almost entirely within Los Angeles. We've gathered this strong local following with a very simple website and concept, and we think there is an opportunity to build a much bigger and more useful platform for dedicated film-goers and the independent venues and programmers that cater to them. We're currently looking to partner with a software engineer / web developer to build an event discovery platform that connects movie-lovers to the best theatrical experiences in their cities. Similar to how dice.fm helps curious music fans discover local shows at smaller, more niche venues, Revival Hub aims to be the platform that helps film fans discover memorable movie-going experiences. We want to test this platform in Los Angeles with the goal of expanding nation-wide.

We're an applied research company building autonomous, collaborative, and socially intelligent agents.

OA Softwares was founded on a simple belief: businesses shouldn't have to outgrow their technology before they can outgrow their competition. As companies grow, they often find themselves constrained by disconnected tools, manual processes, and software that was never designed for the way they actually operate. We exist to solve that problem. OA Softwares is a platform engineering and digital transformation partner that helps ambitious businesses build the digital capabilities they need to scale. Rather than simply delivering websites or applications, we work alongside founders and leadership teams to understand their business, identify opportunities where technology can create measurable value, and engineer solutions that support long-term growth. Our work spans custom software, web and mobile applications, customer and partner portals, AI-powered digital experiences, business process automation, and modern digital platforms. Every solution is designed with scalability, performance, and business outcomes in mind. We're also building OA differently. We're creating a company where engineers, designers, strategists, and growth professionals collaborate to solve real business challenges—not just write code. We believe great technology comes from understanding people, businesses, and the problems they're trying to solve. Our ambition is to become the technology partner businesses turn to when they're ready to build what off-the-shelf software can't. If you're excited about building products that create real business impact, we'd love to build the future with you.
