About Us

Best-in-class business valuations

Derivatas was founded in 2011 by experienced valuation professionals who decided there must be a better way to generate valuations than the time consuming, expensive process that was prevalent at the time. Derivatas developed the first sophisticated software platform for venture valuations, saving hours of tedious work, while at the same time eliminating errors and guaranteeing 100% accuracy in the calculations. The platform and the reports generated save time and money not only in the valuation process, but also in the audit process which follows. Since our inception, we have grown to provide countless mark-to-market valuations for venture funds worldwide and 409A valuations for early stage companies.

Our Services

Unrivaled speed and accuracy

We are specialists in valuations for venture capital funds and the companies they finance – it’s all we are about. Our focus makes us the best at what we do.

Valuations for venture and angel funded companies (IRC 409A)

Since 2004, the IRS has required that stock options be granted at "Fair Market Value” under Internal Revenue Code 409A, and GAAP accounting rules require that the valuation be allocated to each class of security. The process is complex and requires specialized expertise. Even the most experienced CFO’s are seldom trained in this process, so utilizing a specialist firm such as Derivatas is almost a requirement. Penalties from the IRS can be severe for the company and also the recipient of the options, and a poor valuation paper trail can derail a fund raise or liquidity event. A valuation from a reputable third-party firm such as Derivatas gives you “safe harbor” with auditors, the IRS and the SEC. Our belief is that managements of early stage development companies have better things to do than spend time, energy and money on compliance issues such valuations. Derivatas is dedicated to making your life easier at every step – and more economical as well.

Mark-to-market valuations for venture capital funds (ASC 820)

Venture capital funds historically have conducted annual and quarterly valuations of their portfolios internally. In recent years, auditors have been increasing pressure on funds to hire third-party valuation firms to perform the valuations. This process is ongoing and evolving, as more and more venture funds move toward independent valuations. In past years, the cost of valuations has discouraged using third party firms for mark-to-market valuations. Derivatas is breaking new ground in offering affordable valuations for venture funds. Few valuation firms have the experience, insights and skills to work with venture funds on their valuation process. Portfolio valuations require an ability to work with investment professionals and auditors in addition to financial teams. Derivatas has the experience and sensitivity to provide exceptional service at all levels in this process. Our valuation reports for VC clients have been called the “Best In Class” by BIG 4 auditors.

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 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.
