So what

MongoDB's fiscal fourth-quarter revenue jumped 71% year over year to $85.5 million -- a meaningful acceleration from the company's 57% revenue growth in Q3. Even when excluding the company's recent acquisition of cloud database provider mLab, organic revenue accelerated, management noted in its earnings call.

Atlas, the company's multicloud database service, helped drive results as the offering surpassed an annualized revenue run rate of $100 million -- less than three years since its launch.

"At approximately one third of our revenue, MongoDB Atlas' tremendous growth highlights its compelling value to enable customers to focus on innovation and offload the operational burden of database management," said MongoDB CEO Dev Ittycheria in the company's fourth-quarter earnings release.

Importantly, MongoDB's non-GAAP net loss per share was $0.17, narrower than a loss of $0.27 in the year-ago period.
