Launchbit

LaunchBit was an advertising startup founded in 2012 and incubated through 500 Startups, co-founded and led by CEO Elizabeth Yin. It launched as an email ad network that let B2B and software-as-a-service advertisers reach audiences through niche email newsletters, and helped publishers monetize email — a medium BuySellAds founder Todd Garland described as "pretty tricky to monetize." In March 2014 LaunchBit pivoted toward a customer-acquisition and lead-generation platform for SaaS companies. BuySellAds.com acquired LaunchBit in September 2014 for undisclosed terms, and the company no longer operates independently: as of a July 2026 probe, launchbit.com serves the BuySellAds corporate website for every path. LaunchBit published no public API, developer portal, or SDKs, so this profile is retained as a historical/acquired record rather than an active API provider.

Launchbit is profiled on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Email Marketing, and Lead Generation.
