Investment thesis
QuestMark invests at the expansion stage, typically writing initial checks of $5-15 million with reserves for follow-on, and can deploy $25-30 million alongside its limited partners and co-investors. It typically leads financings but will co-invest with growth-oriented partners. The firm favors companies with strong, real recurring revenue and momentum in a proven go-to-market strategy, investing to accelerate clear market leadership. It also funds acquisitions and is open to partial secondary purchases that preserve stakeholder alignment. Areas of particular interest include enterprise software, vertically-focused and mobile cloud software, tech-enabled business services, security, financial technology, consumer internet, and healthcare IT.
