London-based social media and content planning tool ContentCal has raised an additional £610,000, bringing the total amount raised to date to £1.6m.

ContentCal raised from a syndicate of angel investors and existing shareholders.

The cash will be used to further the startup’s technology and marketing activities.

Today’s news follows on from a raise last year and in that time, ContentCal says it’s been preparing for expansion into global markets. The company also claims it’s signed up more than 6,000 businesses.

Alex Packham, founder and CEO of ContentCal, commented on the news: “I’m really pleased to announce our new funding round, largely coming from existing shareholders with some new investors also contributing.

“We continue to see growth in terms of users and revenue for the ContentCal platform, with businesses truly benefitting from what we have created. We are now actively exploring options for our Series A funding round to fuel further growth and I’m excited for the path ahead for the business,” Packham added.

In just over two years, ContentCal has grown from a team to two to 26 people and is being used by companies including BMW, Bouygues, Racing Post, Honda, Oxford University, Water Aid, Royal Mail and SSE.

The startup offers a single platform from which businesses and teams can manage the planning, publishing and collaboration of social media content.
