Iris Associates was an American software development company founded in 1984. It developed the software for Lotus Notes (subsequently IBM Notes). Iris worked under contract with Lotus Development Corporation until 1994, when it was bought by Lotus.

Success of Lotus Notes

Only a year later, in the face of the rapid decline of its desktop business, Lotus itself was purchased by IBM for approximately US$3.5 billion and Notes became branded as IBM Notes. Approximately US$3 billion of this price is generally attributed to the purchase of the Notes business.

At the time of the IBM purchase, Lotus reported that Notes had approximately 2.2 million users. In 2004, nearing the 20th anniversary of the founding of Iris Associates, IBM reported that Notes has over 110 million users.
