Highlights from the enterprise software startups I helped build
rocket taking off through the clouds
Welcome to a brief tour of my startup experience.
I led product development and kept customers happy at three enterprise software startups: Flex.io, Gold Prairie, and Kirix.
Some say building a startup is like trying to assemble an airplane while you're flying it, but I think it's more like shooting the rapids on a surfboard. Here are some highlights from this journey.

What I did at Flex.io
Flex.io was a cloud service for integrating data from Web apps directly into Microsoft Excel and Google Sheets. It gave spreadsheet users a way to get live, refreshable data from the cloud without having to write code or go through an IT project.
I led the product development team, focusing on user experience (UX) and product-market fit.
With the team, I also built a product showcase and spreadsheet template portal for key cloud integrations, including BigCommerce, Crunchbase, HubSpot, Intercom, and Shopify.
Highlights
Flex.io combined a number of technologies that were completely new at the time, from serverless, API-driven data feeds to new features in Excel. This provided some memorable moments:
  • Demoing an early version with serverless data feeds and a CLI at PyCon Startup Row
  • Working as an early test partner with the Microsoft Office product team to leverage their new Dynamic Arrays feature in Excel
  • Collaborating on creating new services with forward-thinking customers, like Crunchbase

What I did at Gold Prairie
Gold Prairie was a Fintech solution for identifying and preventing payment errors, such as duplicate payments and missed discounts. It operated as an automated, internal financial control for accounting staff at large organizations.
I led product development and managed all aspects of the product lifecycle from initial market validation to delivering the solution and building customer relationships.
After 10+ years of growing the company, including raising a small investment round, we successfully exited via a private sale in 2019.
Highlights
Gold Prairie delivered great results and this led to many long-term relationships with our customers (5+ years). Additional things I'm proud of include:

What I did at Kirix
Kirix was an award-winning productivity tool for transforming, cleaning, and analyzing data. It also incorporated a built-in web browser for opening and working with CSV files on the web.
Kirix was a team effort by a small group of founders. I focused primarily on product strategy, product development, and marketing.
Highlights
Kirix garnered media attention and impressed a lot of people, but in many ways it was ahead of its time. We were pioneering data preparation before that became its own product category. Some highlights include:
  • Winning the Product Excellence Award at LinuxWorld Boston 2005 for the "Best Desktop-Productivity-Business Application," beating Sun Microsystems's StarOffice
  • Generating media coverage from InfoWorld, The Register, Computerworld, and other tech news sources
  • Delivering a unique, innovative data analytic feature set, including dynamic calculations across 100+ million records, linking data sets, and browsing Web-based data
