FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.

TestSprite is an intelligent AI Testing Agent and Automation Platform designed to revolutionize the software testing lifecycle. Its core offering is the TestSprite MCP Server, a Model Context Protocol integration that connects directly to your IDE's AI assistant, such as Cursor or Windsurf. This deep integration allows developers to initiate fully automated testing workflows without leaving their coding environment, using simple natural language prompts. By simply asking "Help me test this project with TestSprite" or dragging the project folder into the chat, developers can leverage TestSprite's powerful engine to handle the entire testing process. The platform operates through an intelligent, eight-step workflow. It begins by reading product requirements and analyzing the project's codebase to understand its structure and features. From this analysis, it automatically generates a normalized Product Requirements Document (PRD), comprehensive test plans, and executable test scripts for frameworks like Playwright and Cypress. Tests are then executed in secure cloud environments. A key differentiator is its ability to not only provide detailed reports but also to enable automatic fixes, as the IDE can use its analysis to patch issues. This approach eliminates the traditional burdens of manual test case creation, complex setup, and debugging. The benefits are substantial: developers can ship code 10x faster with professional-grade (90%+) code quality, while teams achieve broader test coverage and significantly reduce manual QA effort.

We specialize in Title IX, ADA/504, civil rights, and equity programs, offering interim leadership, policy development, and professional training solutions nationwide.

Harell Data is building the intelligent infrastructure for the next era of scientific discovery. While AI has revolutionized digital industries, progress in the physical sciences-from drug discovery to material science-is currently bottlenecked because the most valuable training data remains isolated, unorganized, and difficult to access. We are solving this by providing an end-to-end ecosystem that enables the secure sharing of proprietary datasets alongside the high-performance compute and orchestration layer required to train large-scale models. By bringing compute to the data within a single, integrated environment, we are creating the foundational stack that transforms raw scientific data into the next generation of domain-specific foundation models.

Sahova is building the first AI-native operating system for construction. We believe the future of construction isn't another project management tool—it's an intelligent operating system that understands every project, document, conversation, and workflow. Our mission is to simplify and advance how builders and contractors run their businesses through AI.
