Fibo went through Y Combinator in the Winter 2017 batch, describing itself as SaaS calendar and messaging for SMBs. Y Combinator's company directory lists it as Inactive. The directory does not say why a company stopped, and this page does not guess.

Its batch
Winter 2017 had 116 companies in YC's listing: 54 Active, 29 Acquired, 0 Public and 33 Inactive, so Fibo is one of 33 companies from that batch listed as Inactive (28%). Across YC batches at least two years old, 23% of companies are listed Inactive.
Statuses are Y Combinator's own listing in its public company directory, read on the date shown. YC's directory can drop companies altogether, so the Inactive counts here are a floor, not a full count of companies that stopped. Acquired and Public are as YC lists them; neither says anything about the price or the outcome for founders.
The record: Fibo in the Y Combinator directory. Measured 2026-09-26 from Y Combinator's company directory.
