Call Center News in 2021

Leading contact center innovators in 2021

The COVID-19 pandemic caused a massive increase in investment for the contact center market. The crisis instantly changed the nature of customer service. Emerging technologies are also key players in this evolution. All of this has seen an explosion in investment in the call center sector. 

One innovating company, Asapp, saw remarkable investment after growing twofold in the last year. The AI-driven customer service company raised $120 million, and saw a $1.6 billion valuation this year. The company is using AI to bridge gaps between the reality of working from home and customer service needs. 

Other call center companies are also investing in technological developments post-Covid. BT recently raised a whopping £2.2 billion. The company, among other things, is investing in fiber internet connectivity for its UK locations. With the goal of further disrupting telecommunications and customer service BT will use this money for the near future.

 Contact Center Future Trends for 2021

Top contact center trends to watch in 2021

The Rise in Cloud Contact Centers

While in-person call centers have been closed due to the COVID-19 pandemic, the demand for them has not. This is where cloud call center software has shone. Contact center companies are seeing increased productivity, security benefits, and better employee satisfaction. In an industry with record turnover, the latter makes this a key trend to watch in 2021 and beyond.

Contact Center AI Integrations

While AI is touching nearly every industry, perhaps none are more impacted than call centers. Accenture predicts AI will increase contact center productivity by 35% in the US alone by 2040.

AI allows for smarter workflow pipelines, making both customer and employee experiences more positive. Automation of routine tasks, more personalized customer experience, and increased targeting are all bolstered by AI. The customer service industry is utterly dependent on satisfaction and AI increases this in all aspects. As such, this is a trend unlikely to go anywhere soon. 

Is Video Chat Replacing Voice? 

While 2020 was the year of the Zoom call, the future may see this stay in customer service circles. This is an emerging trend, with limited adoption, but the potential benefits are strong. In troubleshooting departments, a visual component can be essential to both solving the problem and limiting frustration. Anyone who has tried to talk someone through a process on the phone will understand the difficulty of voice-only troubleshooting.

The exact nature of the future contact center video chat is uncertain. One-way video is an emerging contender. With more individuals used to Zoom and FaceTime, this may be an unexpected lasting impact of the 2020 lockdowns.
