Startup Operational Support

Simplify your operations, amplify your success.



Nice to meet you, my name is Sivan Arbiv

I thrive when I am able to support people around me to be their best selves - personally and professionally. I have a great ability to connect with people and can often anticipate their needs before they’re expressed. I love coming up with out-of-the-box solutions to complex challenges, and making the unreal - real.

I hold a B.A. in Human Resource Management and have 15 years of experience leading operations, finance and HR functions. I live and breathe the high-tech world and thoroughly enjoy supporting startups in their growth from inception.

I founded S.O.S., Startup Operational Support to utilize my knowledge, professionalism and experience to fill the market’s needs of outsourced operational support to small and medium-sized startups. 

S.O.S. aims to promote the success of your business by providing you with operational management services. With operations running smoothly, your valuable time and energy is freed up to grow your organization, while doing what you really want, love, and specialize in.


In addition to consulting in the fields of HR, Operations & Finance,
