Startup Founders: What's Your Secret to Building a Strong Waitlist? (B2B SaaS for SMBs). I will not Promote

Hey r/startups! I'm building a SaaS solution for small and medium-sized businesses in the US, and we're currently in alpha. While we're making good progress with the product, I'm looking to create momentum and build a strong waitlist of potential users before our beta launch. I'd love to hear from founders who've successfully built waitlists, particularly in the B2B/SMB space. What strategies worked for you? Some specific questions: * Did you use referral systems or early-bird incentives? * Which marketing channels proved most effective for reaching SMB decision-makers? * How did you maintain engagement with people on your waitlist? * What tools or platforms did you use to manage your waitlist? If anyone here has experience building a waitlist for a similar market, I'd especially appreciate hearing about both your successes and failures. What do you wish you had known when you started? Thanks in advance for sharing your insights! Best, AK  I will not promote
