Sphaerist has helped clients in diverse fields, including audit software, pharmaceutical supply-chain risk monitoring, AI call analysis, robotic process automation, education technology and distance learning, information security, telecommunications networks and services, clean water, cloud computing, university technology transfer, mobile applications, intelligent devices and wearables, sports and other data analytics, market research, professional services, publishing, materials science and engineering, brewing, toys and games, and many others.
Sphaerist’s approach to its work is informed by deep experience in technology-centric M&A. We are especially mindful of strategy alignment, intellectual property chain of title, risk allocation, and clarity of drafting. We build strategies, policies, and agreements to serve current business objectives, but always with an eye toward eventual due diligence review.
Sphaerist helps set priorities and manage projects and budgets wisely, while reinforcing value-building behavior, like IP protection, privacy-by-design, and good contracting practices.
For M&A, patent and trademark prosecution, source-code audits, corporate finance, and litigation, we work closely with highly specialized firms. We manage multi-disciplinary projects as our clients’ general counsel – to control costs, focus communications, advocate for business objectives, and reduce internal distractions.
