Houston-based HighRadius Corp. secured $125 million in a series B growth funding round that pushed the software solutions provider to unicorn status, or a startup valued at $1 billion or more.

Technology investment firm Iconiq Capital LLC led the funding round, with participation from existing investors Susquehanna Growth Equity LLC and Citi Ventures Inc.

HighRadius intends to use the new capital to accelerate its continuing platform development and to expand its geographic reach.

Atlas Technology Group advised HighRadius for the transaction.
