The tech startup gold rush continues, and there’s no stronger sign of the times than the amount of venture capital money being raised by these young companies.

In the first quarter of 2018, US venture capital funding across all industries grew 49% from the year before up to $22.1 billion, according to the Goldman Sachs Views from the Valley report, which is based on data from CB Insights.

Deal sizes grew dramatically as well, with investors funding seven unique mega-deals, valued at over $500 million each, during the quarter. In all of 2017, there were only two such mega-deals, according to the report.

While US investments were up 21% from the fourth quarter of 2017, the number of deals was nearly stagnant – up just 5% from the quarter before. The average deal size in the first quarter was $14.1 million, up from $12.3 million the quarter before, and far above the historical average of $8.2 million per quarter, according to the report.
