Maddermore is an AI-powered SaaS platform designed to help remote sales managers improve team engagement and reduce sales rep stress through behavioral science and data integration. Co-founded by Matt Schenker (licensed therapist and management trainer) and an enterprise sales veteran, the company is currently in beta after a year of research involving 400+ sales team interviews. With a newly onboarded founding CTO from medical AI, they aim to launch an MVP within 6-9 months while running paid pilots with existing customers.

Adam Robinson launched RB2B in March 2024 as a B2B lead generation tool after building Retention.com to $23.8M ARR with 6 employees. Using controversial LinkedIn storytelling (including posting about a cease-and-desist letter), he generated 1,600+ leads pre-launch with a 10% free-to-paid conversion rate. RB2B grew from $0 to $200K MRR by September 2024, adding an average of $60K new MRR per month, driven primarily by organic LinkedIn content and a simple freemium model.

Jungle Scout is a product research and market intelligence tool for Amazon sellers, founded by Greg Mercer in 2015. Starting with just $1,000 and no coding experience, Greg built a Chrome extension to automate his own product research process, then validated demand by posting demos in Facebook seller groups. The business has grown to 35+ remote team members with multiple seven figures in annual revenue through content marketing, educational resources, and influencer partnerships, despite higher-than-average churn rates due to the episodic nature of product research.

Referral Rock is a SaaS platform that helps businesses design, launch, and manage customer referral programs. Founded by Josh Ho in December 2013 after overhearing a conversation at a car dealership, the company grew from 500 free users to $70K MRR through bootstrapped, organic growth driven by inbound marketing, content, and inside sales. Today the 14-person remote team operates at near 5% churn by focusing on customer success and consultative selling.

Bonjuro is a SaaS product that helps businesses build customer relationships at scale through personalized video messages. Founder Matt Barnett initially used the system while running a market research agency, recording personalized videos on his ferry commute to convert leads across time zones. After a client requested the tool, he built a basic MVP in a weekend and charged $15/month, achieving 40,000+ users through viral product mechanics, influencer partnerships, and intense customer focus including personalized welcome videos for all signups.

Salesflare is a sales CRM built by Yaroon Cortout and co-founder Michael Farmer that automates data capture from emails, meetings, and other sources, eliminating manual CRM updates. Starting from Yaroon's own pain point using Salesforce at a marketing agency, the product evolved from a Salesforce integration play into a standalone CRM for small B2B companies, particularly marketing and software development agencies. Through 2+ years of manual sales, PR efforts, a Product Hunt launch (200-300 trials, #1 CRM ranking), and a massive AppSumo campaign (6,000 signups in 3 weeks), the company has grown to serve over 2,000 customers and raised over $1 million.
