A soft launch is aimed for Q2, with a wider marketing push to follow in Q3, in time for the start of the next English Premier League and major European sport league seasons.
The agreement is expected to have a "moderate to high impact" on Scout Gaming's H2 revenues.
Scout Gaming's CCO Joakim Renman said: “I’m very excited to have the privilege of launching our fantasy sports product on ATG.se, thus reaching a wider potential player base than ever before.
"ATG has in a short time proven to be very agile in its expansion into new products, therefore it is not a surprise they now are first to seize the opportunity of being an early mover in a fast-expanding trend within fantasy sports."
ATG's head of sports betting, Christian Erlandsson, added: “We try to constantly offer our customers exciting new experiences and are keen to add fantasy sports as, what we hope will be, a key vertical offering for ATG moving forward.
"We have watched this game format grow in popularity around the world and believe Swedish customers will also appreciate this exciting product. With our almost 50-year legacy of offering pool games and recent expansion into sports betting we believe we have primed for a successful rollout of daily fantasy sports to the Swedish sports audience."
In an exclusive interview with Gambling Insider, Tekkorp Capital CEO Matt Davey previously explained why his firm had invested in Scout Gaming, which "has approached the daily fantasy sports market in a way we think scales."
