Email marketing service provider MailChimp announced last week a new $1 million dollar fund for startups building products that integrate with the service's MailChimp API. MailChimp's program is somewhat unique in that they won't be asking for equity from the companies they fund. It's a pretty attractive deal for prospective partners and a trail-blazing move for a platform in an increasingly competitive industry.
LeadLedger, sales intelligence platform, recently launched the Sales Lead Generation API. The API enables companies and sales forces to access lead information, competitive data, client details, and more from third party apps and existing workflows. Developers can integrate prime sales data into existing tools or build new apps to track and monitor sales progress.
