Top Tech Startups to Work For in 2027

SellerGeni is redefining how e-commerce sellers win in the world’s most competitive marketplaces. Marketplaces like Amazon have become pay-to-play arenas where visibility determines survival. Yet the tools for managing ads remain complex, expensive, and built for enterprise teams, leaving millions of sellers struggling to keep up. We’re changing that. SellerGeni’s AI-powered platform acts like a virtual performance marketing team. We automate ad campaigns, optimize bids in real-time, and turn fragmented data into clear insights—all so sellers can grow faster and more profitably without managing dashboards or hiring costly agencies. Our technology adapts to each seller’s size, budget, and goals. Whether it’s launching new products, scaling ad spend, or protecting margins, SellerGeni handles the complexity, allowing sellers to focus on running their business. The opportunity is massive. E-commerce advertising is a $100B+ market and growing. Yet most sellers are still underserved by legacy tools that weren’t built for today’s pace or scale. We’re building SellerGeni to become the default solution for marketplace advertising, helping sellers of all sizes compete like top-tier brands. We’re growing rapidly, managing millions in ad spend for thousands of sellers across multiple marketplaces. Backed by deep expertise in e-commerce, AI, and performance marketing, we’re assembling a world-class team to take SellerGeni global. We’re looking for visionary talent and partners to join us in transforming the future of marketplace advertising.

For the past 150 years, pathologists have been inspecting tissue visually under a light microscope to diagnose and grade cancer. This process is subjective--for many cancers, pathologists only agree with each other about 50% of the time.

We tap into that digital data, and use computers to automate and quantify modern pathology workflows.
