Any tips for marketing B2B SaaS products to drive testing / adoption?

Myself and my team are building a B2B SaaS product for web development and we are nearing our beta launch. We've built an AI Project Management tool specifically designed to save project managers and web developers time by automating the most time consuming parts of the web development process, including project scoping, project tracking, budget tracking, developer management, workflow processes, and status updates. Do you have any suggestions, be it channels, methods, or just general tips for marketing our product, to drive testing and adoption so we can get some feedback and begin to grow?
