Eagle Eye, which specialises in electronic coupons and loyalty schemes, is aiming to raise about £6 million through the initial public offering (IPO).
The Guildford-based firm has also agreed to buy mobile technology outfit 2ergo for £2.5m in cash and £2m in shares.
Chief executive Phill Blundell said: “Eagle Eye is growing rapidly in the fast expanding market for digital coupons and payments. The acquisition of 2ergo accelerates that growth through acquiring blue chip customers, valuable intellectual property and an experienced management team.
“The IPO will provide us with the capital to maintain our UK market leadership and enter lucrative overseas markets.”
