GNAP
Gina Tost, a journalist with experience covering mobile technology and startups, built GNAP as a platform to solve a coordination problem in the mobile app promotion space. The platform acts as a transversal marketplace connecting three parties: app advertisers looking to promote their apps, publishers and bloggers wanting to monetize their audience, and networks needing diverse, cost-effective campaigns.
The business model is straightforward—bloggers embed smart links or white-label app stores on their content (like a blog post about photo editing apps). When readers download apps through these links, GNAP pays the blogger on a cost-per-install (CPI) basis, ranging from $0.80-$1 for Android in Barcelona to $2-$3 for iPhone in the US. GNAP takes a 30% commission from advertisers spending a minimum of $100 per month. The company had integrated with every major player in the ecosystem, giving them a transversal view of the market.
GNAP grew entirely organically through word-of-mouth. Gina explicitly stated: "everything is organic. We are not spending anything on marketing." The Barcelona tech ecosystem embraced the platform, and by early 2016, GNAP had become "kind of famous here" locally despite being a B2B company. This organic growth was particularly impressive given they were competing in a complex, multi-sided marketplace.
By January 2016, the company had reached significant traction: they were working with 350 advertisers and over 700 publisher sources (bloggers and content creators). In total 2015, they processed $750,000 in advertiser spending and generated approximately $320,000 in revenue. In a single month (January 2016), they processed about $100,000 in advertiser spend, suggesting growth momentum. More than 10,000 bloggers had earned at least $10 through the platform, with many earning substantially more.
The company had raised $100,000 in seed funding 18 months prior and remained profitable, funding growth from operations. As of the interview (early 2016), Gina announced they were raising a Series A round of $500,000 at a $5 million post-money valuation ($4.5M pre-money) with two venture funds. The team of five was all based in Barcelona and planned to use the capital to build out their marketing efforts and scale the business.
- •The founder's deep expertise in mobile technology and startup journalism gave credibility and insider knowledge that attracted both advertisers and publishers to a complex three-sided marketplace from day one.
- •Word-of-mouth growth in a B2B marketplace typically requires solving a real coordination problem so effectively that users naturally evangelize it, which GNAP achieved by connecting previously fragmented app promotion channels.
- •The usage-based pricing model (CPI commissions) aligned incentives across all three parties—bloggers earned more when they drove quality installs, advertisers only paid for results, and GNAP captured 30% of advertiser spend—creating a self-reinforcing ecosystem.
- •Achieving $30k MRR profitably with zero marketing spend while raising a Series A demonstrates that marketplace network effects and organic traction are more valuable to investors than customer acquisition metrics in competitive spaces.
- 1.Build deep domain expertise in your target ecosystem before launching: spend time as an insider (journalist, operator, or consultant) in the industry you plan to disrupt so you understand pain points and key stakeholders authentically.
- 2.Design a marketplace pricing model where all parties benefit from increased volume, not just your company, so users naturally refer others to grow their own earnings or reduce their costs.
- 3.Focus initial go-to-market on a concentrated geographic or community hub where you can become locally famous through relationships before attempting broader scaling, allowing word-of-mouth to prove the model works.
- 4.Integrate with all major existing platforms and networks in your ecosystem rather than forcing users to choose sides, which reduces friction and positions you as a transversal solution that makes the whole system more efficient.
