RightKit

Saul Fleischman didn't start RightKit to raise venture capital or build a unicorn—he built it to solve a problem he and other social media marketers faced. Back in January 2012, the social media marketing workflow was fragmented: marketers would work in professional tools like Hootsuite, Buffer, or Sprout Social, but had to leave those tools whenever they needed hashtags. RightTag, the original browser extension, solved this by letting users right-click and instantly get hashtag suggestions without leaving their workflow.

What started as a single tool grew into something bigger than expected. Over 8.5 years, RightTag accumulated between 20-25 million visitors and converted 431,000 of them into registered users. However, Saul discovered a critical monetization problem: people didn't want to pay for RightTag. The core issue was psychological—users thought of browser extensions as free tools (like Adblock), even though this one delivered value. The Chrome extension alone has over 20,000 users but low conversion to paid tiers.

Rather than force people to pay for RightTag, Saul took a bold approach: he broke the original tool into four separate products (RightTag, RightWrite, RightForage, RightBoost) and built additional tools around specific use cases. More importantly, he launched an API with 19 endpoints serving different markets—from company logo retrieval to image generation. Each endpoint could be priced independently based on the value it delivered. The package bundle, introduced just two months before this interview, became the most successful product in five years, bundling all tools at a 45% discount. Pricing ranged from $49/year for basic RightTag (hashtag help only) to higher tiers, with the API starting at $49/month for Tier 1 access. The model shifted from per-user subscription to usage-based credits, where customers pay for access to a tier of API calls rather than just what they consume—paying for peace of mind that they won't hit rate limits.

The API became the surprise winner. Unlike the browser extension that required expensive customer service, the API was largely self-serve. With somewhere between 10-100 million actions processed per month across all endpoints, the API generated significantly more revenue than any individual product. Saul calculated that at Tier 1 ($49/month for 50,000 credits), the business was doing at least $6,000+ in monthly revenue from the API alone, though he declined to share exact figures. The RightKit Package showed $2,600/month in a March 2020 update on Indie Hackers—the last publicly disclosed figure.

After 8.5 years, RightKit operates as a lean, fully bootstrapped team of 5 (with 4 engineers) based in Prague, Czech Republic, with Saul running operations from Osaka, Japan. They've never raised capital and have no interest in doing so—Saul and his CTO Michal studied venture deals and concluded the loss of control wasn't worth it. The team is profitable with infinite runway, processing tens of millions of API actions monthly across 19 different product endpoints. Saul remains optimistic about growth, focusing on expanding the package bundle and strengthening existing API solutions rather than chasing outside investment.
