2021. The year that brought us "work from work" Thursdays, Caliper 4, and many new headshots. It has been a year of growth, expanded relationships, new opportunities, and adjustment to the new normal of uncertainty. At times it seemed like we teetered on the edge of controlled and chaotic growth. Fortunately, we continued to source and hire great candidates and have invested in employee on-boarding and development. Our team now exceeds 20 consultants who worked on over 75 projects for 40 clients this past year.
In addition to the pandemic, clients have been challenged with resource constraints, supply chain issues, and rapidly evolving market conditions. Through all of this, most have persevered and continued to see growth while making significant investments into their software and data systems. Your resilience has fueled our growth and we greatly appreciate the trust you place in us as you navigate these challenges. As we continue to grow our team, we do so with you in mind, focusing on our client commitment of lasting relationships, practical insights and exceptional service.
From a services perspective, we grew in all areas of the business including IT strategy, project management, implementation support services, analytics, and integration development. We also continued to expand our hosted Caliper Analytics offering to service Community Development Financial Institutions (CDFI) along with Construction industry clients. We invested almost 3000 hours into product R&D and rolled out a new user interface with Caliper 4. From an industry perspective, we saw significant growth in the nonprofit, CDFI, and life science sectors while continuing to serve construction, professional services, and manufacturing clients.
Externally, we returned to the road in a limited capacity for conferences and client visits. What appeared to be a ramping up of travel has trended the other way as the winter months have set in. We have continued to adjust to the hybrid model. We seem to have settled into regular in-person meetings for various teams on different days along with quarterly all-hands meetings. This cadence seems to be a good blend of the work-life balance our team members seek while preserving our culture and satisfying the desire to interact in person.
As we look forward to 2022, we approach it with optimism. Business investment in software and data initiatives has continued to be strong with high returns associated with these strategic technology projects. 2022 will certainly be another dynamic year for us! We at ATX look forward to a bit of a holiday break before we get started and hope that you all have the opportunity to do the same.
