Trustworthy Valuations

At Derivatas we stand behind our work. If you are ever challenged to defend the valuations performed by Derivatas, we will assume responsibility for explaining and defending our valuations with auditors, the IRS or the SEC.


  • Derivatas was initially referred to us by a BIG 4, and they came highly regarded. The Derivatas professionals know exactly how to work with our BIG 4 auditors along with our finance team to foster a collaborative and trusting environment. Their deep expertise and strong relationship skill have carried us through several audit cycles already. Can’t say enough how much we love working with them!

    Cinthia Sheu VP Finance, Vivo Capital
  • Derivatas provided a 409a valuation for a client requiring a significant change versus a prior valuation by another firm.  They helped us understand why the new valuation methodology would be necessary for the company to survive a future audit and avoid a potentially damaging outcome.  Working with Derivatas was both enjoyable and enlightening, and I will be using them with all my clients in the future.

    Scot Mollot Interim CFO in Silicon Valley
  • The Derivatas team has always provided an easy to follow analysis in a clear and detailed overview format. They provide a knowledgeable interface with auditors and a quick turnaround on reports. They are reliable and have saved us a lot of time and headaches.

    Daniel Barakat VP Finance, e.ventures
  • We had a great experience working with Derivatas. Your team was so helpful, and you saved us a lot of time and money. And our auditors were very complimentary of the quality of your report.
