The sellers, Advent Private Equity and Local Globe III Limited, will subscribe for 2.4m new shares in Twenty at 7.2p per share for a total of £0.175m.

Advent Private Equity Fund IV will hold 3.44% of the share capital, Advent Management IV Limited Partnership 0.03% and Local Globe III 0.72%.

Twenty will issue additional shares based on revenue targets over five years, capped at 5.81%.

Moveme made a loss of £2.1m on turnover of £0.25m in the year to January 31 2009.

Twenty's CEO Ian Lancaster said, 'The acquisition of Moveme represents a step change for the group and is consistent with our strategy of developing our business model around providing data and customer intelligence solutions.

'The addition of Advent Private Equity as an investor in Twenty is welcomed as we have gained a strategic investment partner who shares our vision.'

Twenty said the acquisition secured a valuable data asset, providing valuable consumer prospect data on consumers at the point they move house.

'This data has considerable value to utilities, telecoms providers, media and financial services organisations where the house move is a trigger to purchase.'

The Moveme business was enabled by the combination of client relationships held by Twenty group companies, specifically through its strategic relationship with Royal Mail.
