Kafka has established Woodgate Consultants to provide strategic comms and marketing advice for corporate, financial services and individual clients.
Most recently, Kafka was global head of marketing at Swiss investment bank UBS, leaving in February when an internal reorganisation had put his role at risk of redundancy.
He joined UBS in mid-2010 after four years heading EMEA corporate comms at Goldman Sachs. He has also previously led corporate affairs at the London Stock Exchange and worked for Fidelity International, Nomura and Hoare Govett.
Kafka said that Woodgate would tap into the demand from the public, governments and regulators for 'behavioural change and much clearer accountability from business'. The firm will provide comms audits and strategy, brand development, contingency planning for crises and client relationship marketing.
Woodgate will also offer personal comms training to clients' senior management.
Initially, Woodgate will have no other full-time employees and will use external support on a consultancy basis where required.
Kafka said of his consultancy: 'The challenge for business today, in the new era of social media, is to restore public confidence while growing profitability.
'Comms activity through all channels, both internal and external, is an essential requirement for companies and senior management to promote transparency and understanding, reflecting long-term behavioural and cultural change.'
He said he was already in 'advanced discussions' with a number of potential clients.
