About Coffinity

Coffinity was founded by Mike Long in 2000. Mike had served as CFO for two early-stage VC firms and as CFO of a start-up technology company, and he wanted to make an impact with tech companies directly. 

At Coffinity, our goal as your partner is to help give you your best chance to build something great, by implementing robust financial management processes and structures that can scale, and by giving you access to expert financial analysis and strategic guidance.

The team is based in Delaware, the legal home of many great companies and a beautiful place to call home as you can see from the photos.

From Zero to $20M Revenue and a Strategic Exit

As acting CFO with Interactive Clinical Technologies we helped the two co-founders grow the business into a material niche player servicing clinical trials, with zero need for outside equity. We fought through all the challenges: from dicey cash management issues, to rudimentary operating issues, to securing a line of credit, to establishing option plans, to recruiting advisors and ultimately to final negotiation for sale of the company. The sale was to Galen Pharmaceuticals for a multiple of revenue.

Evan Rosenbaum

CPO / Co-Founder, Genies

"Mike Long has been a fantastic member of the Genies executive team. He has helped us grow from a few employees to over 30 by putting in place practices and systems to enable and sustain growth. His insights have helped us scale our revenue, track spending, and do effective financial projections. Mike and team are key parts of the Genies growth story."

Jon Gowa

CEO, Bloom Automation

"Coffinity has been absolutely essential in allowing our robotics start-up to focus on the technology, not the day to day financials. As a CEO, and a VP of Engineering, my roles are already split thin. Unloading everything from our book-keeping to purchase orders and accounts payables, and even proforma generation and counseling, allows us to focus our time on the nuts and bolts."

Jason Campbell

Co-owner, Slack Tide

"Mike and Annmarie have been a trusted and integral partner in the growth of our company. Their knowledge and guidance from the first day we opened to now has helped our company grow exponentially in the 4 years we have been in business. We could not be happier with their work and focus on helping us grow."
