Sideline Swap is a two-sided marketplace for buying and selling used and new sports gear founded in 2015 by Brendan Candon. The company grew from $400k in transaction volume a year prior to over $3 million in total lifetime transaction volume, with $2 million processed in the first seven months of 2017, growing 30% month-over-month through a flywheel of supply acquisition (15,000+ sellers) and demand generation (23,000+ buyers) powered by social media and influencer marketing. Brendan raised $3 million in total funding and built a team of 10, projecting $5-6 million in revenue for 2017 while maintaining an 80% average order value.

First customers: Direct outreach to college athletes, professional athletes, and people in the sports industry who had accumulated gear; leveraged existing networks and connections.

MealSurfers was a two-sided marketplace connecting home cooks with customers seeking affordable, healthy meals in downtown Toronto. Founded by Ali Jiwani in 2015, the startup grew after a CBC Radio interview brought thousands of signups but struggled with low customer retention (less than 10% repeat purchases), regulatory challenges from Toronto Public Health, and lack of focus on its business model. Ali eventually exited the company after about 2 years, selling it above market price to a private fund.

Founded in 2013 by Ethan Appleby, the platform had 5,000 active artists and 100,000 lifetime buyers by March 2016, generating $1.6M in revenue in 2015 from nearly $5M in total art sales. Apple selected Vango as one of its top apps.

Side Line Swap is a community marketplace where middle school, high school, and college athletes buy and sell used sports gear. Founded in 2012 as a side project and launched formally in June 2015 after raising $120,000 in friends and family funding, the company has grown to over 2 million in gross sales with 12,000 monthly active users and is growing 15-50% month-over-month. The team leverages content marketing and social media (150,000 Instagram followers across six sport-specific accounts) to drive user acquisition and are raising a $1.5M seed round.

Creative Market was a marketplace for buying and selling handcrafted design content (fonts, graphics, icons, etc.) launched in 2011 by Aaron Epstein and co-founders. The team leveraged their existing 1 million-user Color Lovers community and executed a sophisticated seven-strategy playbook to simultaneously build buyer and seller demand: teaser page with $5 credits, viral referral program with tiered incentives, free goods program, favorable 70/30 commission terms, and relationship-based marketing. The marketplace grew to launch day with 70,000 signed-up buyers holding $350,000 in potential credits, generated $3,000 in sales on day one, and was acquired by Autodesk for an undisclosed amount 16 months after launch.

First customers: Teaser page with $5 in free credits and viral referral program, promoted through Color Lovers existing community of 1 million users

Lieferoo was a marketplace for peer-to-peer logistics and awkward items that couldn't be shipped as packages, founded by Aazar Shad in Germany in 2014. Despite validating the idea with ~100 travelers and building an Airbnb-like platform, the startup failed due to poor marketing (relying only on organic Facebook growth without paid ads), bad team fit (co-founders lacked commitment), and cultural barriers in Germany's distrust of online peer services. The startup shut down after 1.5 years with minimal financial loss but significant time investment.
