ABOUT SISU

 

SISU is a modern outsourced Finance & Accounting (F&A) services firm purpose-built for startups and growth-stage companies. We combine the scalability of contract staffing with the strategic oversight of experienced CFOs and Controllers.  Unlike traditional staffing firms that only place resources, SISU builds out the processes, structures, and reporting frameworks that ensure seamless implementation and long-term scalability. This approach allows clients to benefit from cost-effective staffing solutions without sacrificing the rigor, reliability, and accountability expected from an in-house finance organization.
