Our favorite startups from 500 Startups’ 18th class

500 Startups’ 18th demo day wrapped up this afternoon in San Francisco. The companies that presented ranged from financial technology all the way to yet another attempt to try and fix conference calls.

500 Startups has to compete with a lot of other accelerators like Techstars and Y Combinator, and in order to be successful it needs to generate hits from these classes. The firm has had some successes — cloud-based call center software startup Talkdesk being one of the most successful — but there’s always a lot of variety in the companies that launch.
