In September 2025, DoraHacks, a global hackathon and developer ecosystem platform, announced the launch of BUIDL AI 4.0: The DevRel AI. This represents another significant advancement following BUIDL AI 3.0's fully automated hackathon community, marking the entry of developer relations (DevRel) into the automated era. Over the past few months, BUIDL AI 3.0 has helped organizations around the world significantly lower the barrier to entry for hackathons. From page setup and automated project review to AI-powered scoring and judging, hackathons have evolved from a demanding operational workload into an innovative activity that any organization can easily launch. However, after a hackathon, transforming the short-lived buzz into long-term developer relationships and ecosystem contributions remains a core challenge for organizers. Hackathons: The Most Effective Developer Relations (DevRel) Tool Hackathons have long proven to be a highly effective tool for attracting new developers, quickly validating ideas, and building community engagement. They quickly ignite participant enthusiasm and showcase technical prowess. However, transforming this short-term buzz into long-term ecosystem value still presents numerous systemic challenges for organizers: difficulties in scalable coaching, a lack of post-event support, and high operational costs. DoraHacks has officially launched BUIDL AI 4.0: The DevRel AI, a paradigm shift from "hackathon automation" to "developer relationship automation." Its core mission is to make every hackathon an engine for long-term developer ecosystem development.
Core Feature Highlights
BUIDL Hub: DevRel strategic command center. Organizers can create BUIDL groups to aggregate potential projects and set clear growth goals.
BUIDL AI Agent: A project-specific AI collaboration partner. It automatically tracks project progress, provides targeted feedback and guidance, and helps developers iterate quickly and grow continuously.
Full Lifecycle Support: From pre-competition recruitment and education, to in-competition companionship and feedback, to continuous follow-up after the competition, BUIDL AI 4.0 ensures that developers don't leave after the hackathon, but gradually become long-term contributors to the organization.
Reinventing Developer Relations
Developer relations are the core mission of every platform technology organization and determine the success or failure of ecosystem building. DevRel work has long faced difficulties in scalability, lack of sustainability, and high costs, all of which have limited the efficiency and depth of community building. BUIDL AI 4.0 is fundamentally addressing these challenges through a new solution:
Scaled Interaction: BUIDL AI 4.0 can maintain in-depth communication with hundreds of projects simultaneously, bringing DevRel work to a new level of efficiency.
Efficient Operations: Automating repetitive tasks significantly reduces operating costs, allowing organizers to focus on high-value strategic decisions. Deepening Ecosystem Development: Through continuous AI coaching and follow-up, more outstanding BUIDLs are able to grow into tangible and valuable achievements after the competition, ultimately transforming into sustainable ecosystem assets. Hackathons have always been the most effective tool for developer relations. BUIDL AI 4.0 extends this value from short-term hackathons into a long-term growth and value engine, enabling any organization to continuously build developer communities and technology ecosystems. BUIDL AI 4.0: The DevRel AI is not only a significant expansion of hackathons, but also redefines the developer relations model. Going forward, DoraHacks will continue to foster the global developer movement, enabling every organization to embrace innovation faster and more broadly through intelligent tools.
