Our Humble Beginnings...

Trivium was started much like any other startup, with a recurring problem and no solution in sight. Beginning in the early 1990s, entrepreneurs were seeking out guidance from our CEO to build and manage Accounting, Finance, and HR teams. These companies did not need full time resources and it was difficult to get part-time contractors to work well with each other.

An Entrepreneurial Awakening

After working on several successful exits, helping in building a venture fund, being on a prominent public company M&A team during the peak of the market, and investing in startups, our CEO continued to see the same issues arise for early to mid-stage companies in the 2000s. It was then that she decided to come up with a solution that would provide peace of mind to entrepreneurs. She began putting together a team of trusted colleagues that were specialists in particular fields with a focus on early to mid-stage companies.

Startup takes Shape

Although Trivium was officially formed in January of 2009, the founding team had been working together for several years supporting companies from inception through the acquisition stage. Since 2009, Trivium has grown organically through referrals from current and prior clients. Since our inception the goal at Trivium has always been the same: provide value, be a partner not a provider, and do for our clients what we would do for ourselves.


The Trivium Engagement process comprises three stages designed to deliver outstanding results.


The Analysis phase is a two-step process. First, we review your current needs to tailor an appropriate level of service and create a statement of work (SOW). – Next, we perform a Strategic Assessment, which addresses the level of service required to implement a support plan that will deliver outstanding value.

The Implementation phase will benchmark ‘best practices’ appropriate to your field, and standardize your business support processes.

Operations and Monitoring

Trivium takes over full-scale operation of in-scope services in this phase with an ongoing commitment to monitor services undertaken and continually improve all aspects of operations.


An organization always requires strong collaborative support functions, but there always stands the concern regarding scalability.

Trivium offers a number of flexible support models serviced by experts in their respective fields. We eliminate learning curve and provide a quick turnaround in providing effective solutions, upon evaluation of client business needs.

We offer multiple levels of support to startups and established businesses; as a result, our clients reduce cost, increase efficiency, and maintain their focus on developing their products or services to grow their business.

Trivium Philosophy

At Trivium, we value the importance of being a good corporate citizen, and as such, we constantly hold ourselves to the highest ethical standards both in the workplace and outside of it.

We set our goals to deliver superior service to help solve our clients’ most pressing business problems. We believe in doing the right thing even if it may compromise our short-term profitability. We don’t waver from the truth or crater under pressure. We are willing to be sufficiently creative and flexible, but always operate under a high moral, ethical and legal standard.

Trivium Core Values


We believe in the absoluteness of integrity and conduct all our internal and external relationships with honesty, and by following the principle of always doing the right thing.

Commitment to client success through excellence in execution

We are committed to doing what it takes to ensure client success. We invest and innovate in the field of business and technology execution to bring leading edge ideas to clients.

Long-term relationships with clients, employees, and partners

We invest in relationships with clients, employees and partners with a long-term perspective and believe our success lies in their success.

# One global firm - with global conduct

We will always maintain a one-firm culture, adhering globally to a common set of professional principles, client service standards and values.

Contributions to a better society

Recognizing our social purpose, we create value aimed at contributing to economic, social and environmental efforts in the communities we serve.


Trivium Corporate Solutions offers a number of flexible support models in accounting, finance and HR. As taxes have always been an integral part of any accounting service package, we began to provide tax consulting and tax return preparation. In response to that growing need Trivium Tax and Compliance spun out of Trivium Corporate Solutions in 2010.

We offer multiple levels of support to startups and established businesses; as a result, our clients reduce cost, increase efficiency, and maintain their focus on developing their products or services to grow their business.

At Trivium T&C, we understand the extreme complexity of the US tax code. We handle our clients’ tax issues so they can focus on growing their businesses, not dedicate their valuable resources to navigating complicated tax rules. Our foremost goal is to make sure our clients are compliant with their current tax filing requirements. We also provide strategic tax planning services and representation before the IRS.
