Ian Culverhouse has dipped into the transfer market to bring highly-rated defender Joe Robinson to the Walks.
The 22-year-old centre-back has arrived from Cambridge City, where he made 23 appearances this season, and goes straight into Lynn's squad for the home visit of Leiston on Saturday.
Director of football Robbie Back said: "Joe is a player who we've been looking at for some time and he fits the mould we are looking for here at King's Lynn.
"He's a confident lad, a good talker and has been captain for a number of clubs. He is ambitious and wants to play as high as he possibly can.
"More importantly, he has experience of this level having played for Bishops Stortford last season where he made a good impression with Ian.
"He wants to improve under the guidance of Ian and Paul. We spent a good hour-and-a-half with him earlier this week and we are pleased to get him on board."
Robinson learned his trade at Ipswich Town, having been part of the academy since he was 12, but after loan spells at Woking, Boston United and St Albans City, he was released at the end of the 2016-17 campaign.
From there, the youngster signed for Bishops Stortford and made 44 appearances, scoring five goals, in the 2017-18 season.
The club hope to be in a position to announce a second signing later this week.
An interview with Lynn's new arrival will appear online later this evening.
