Two Powerhouses. Now One.
In December 2022, GSI acquired Flawless Inbound Inc., a move that created the most complete enterprise technology partner in the market. Here's who each company is, and why together they're greater than the sum of their parts.
GSI, Inc. — The Enterprise Backbone
Founded in 2004 and headquartered in Atlanta, GA, GSI is an Oracle Platinum Partner and full-service enterprise technology consultancy with 100+ certified experts averaging 15+ years of real-world experience. GSI has been named to the Inc. 5000 list of fastest-growing companies and is trusted across North America for mission-critical ERP, cloud, and managed services.
Flawless Inbound — The HubSpot Specialists
Founded in 2014 in Edmonton, AB, Flawless Inbound built its reputation as one of North America's premier HubSpot partners — with over 250 clients across the US and Canada, 30+ HubSpot certifications, and a rare Advanced Implementation Certificate. Their specialty in RevOps strategy and NetSuite/HubSpot integrations is unmatched in the industry. Liliane Youssef, CEO and co-founder, continues to lead as President within GSI.
Straight from the Top
We are honored to have the Flawless Inbound family join the GSI family. We've worked very closely with them and have tremendous respect for their people, their expertise, and their outstanding client relationships. With this union, our clients now have access to the most comprehensive mix of HubSpot solutions and services in the industry.
Flawless Inbound's vision is 'Exponential Growth,' and we believe joining forces with GSI will be a key accelerator to this vision. Our employees, clients, and partners will benefit from GSI's wealth of knowledge, processes, and resources. We're excited to help create an industry leader in the HubSpot marketplace.
