Built by Engineers, Led by Purpose
Poinsettia Circle LLC was founded on the conviction that great technology outcomes come from thoughtful architecture, disciplined engineering, and genuine partnership with our clients. Based in Danville, California, we serve organizations across the United States who seek a higher standard of technical execution.
Our Practice
We operate at the intersection of systems engineering, software development, and strategic technology advisory. Our engagements range from greenfield architecture design for emerging companies to complex system modernization for established enterprises. Every project benefits from the depth of experience our team has accumulated across financial services, healthcare, logistics, e-commerce, education, and public sector domains.
Poinsettia Circle LLC is registered in the State of California and operates as a Professional, Scientific, and Technical Services firm under the Computer Systems Design and Related Services classification. Our development team, Poinsettia Circle, brings together engineers with backgrounds in distributed systems, cloud architecture, cybersecurity, and enterprise software — providing clients with a single point of accountability for complex technical initiatives.
Our Principles
Every project begins with a rigorous architectural foundation.
Security is not an add-on; it is engineered into every layer.
We measure success by business results, not technical outputs.
Clients have full visibility into progress, challenges, and decisions.
