Interfere’s mission is to build the “self-healing layer of the internet”: software that detects bugs, figures out a root cause, and ships its own fix – all before a human can open logs. Unlike traditional observability tools that aim to make logs easier to read, Interfere will eliminate the need to read logs at all.

How this is counted
Companies are the ones Y Combinator lists in its own directory, with the batch it published. A latest raise is the company's newest round beyond the batch itself; its amount links to where it was reported, and totals sum the rounds that link to a source. Founders are the people on record at each company. The same data as JSON: /api/v1/accelerators/yc. All accelerators.
