Today, contract life-cycle management platform Ironclad Inc. announced it raised $100 million in a Series D funding round. In four short years, the Silicon Valley-based company has raised $181 million in a crowding contract management market.

Ironclad's recent investment round was led by venture capital firm BOND with participation from Lux Capital. Funding in the Series D round was also secured from Accel, Sequoia Capital and the Y Combinator Continuity, investors that previously  participated in Ironclad's $50 million Series C round in September 2019. Sequoia Capital also led Ironclad's $23 million Series B funding round announced in January 2019, according to a press release.

The new investment represents exponential growth for a company that less than four years ago completed a Series A funding round worth $8 million.
