Customer Success Stories - Gigantti


Sellforte produced a case study together with Gigantti, the biggest home elecronics retailer in the Nordics, and Screensforce, a marketing body for commercial television in Finland. The case findings include the following highlights:

  • TV is the largest sales driver when considering effectiveness, scalability and media spillover & saturation effects
  • SEM is the most efficient medium in immediate sales generation
  • In conjunction with TV, direct mail reinforces a robust Top of Mind position

In addition to measuring the exact media ROI, Sellforte discovered the importance of different campaigns in building a strong brand image.

Client Context

  • In 2018, Gigantti's turnover was 563.5M€, and it employs over 1100 in Finland
  • Gigantti's motto is 'It’s simply stupid to pay too much'
  • Gigantti is a part of Dixon’s Carphone group, a concern with a turnover of 10.52 billion GBP and 2139 stores across the globe

  • Today, Gigantti carefully considers how tactical and brand marketing support each other
  • Until recently, there have been no tools to measure all marketing with common metrics

Client Objectives

Gigantti aimed to establish a systematic measurement process with common metrics for all its marketing activities:

  • Gigantti's media mix is extensive, and sales are constantly monitored. Observing the effectiveness of marketing is particularly crucial in the busy and highly competitive home electronics sector
  • Previously, Gigantti's marketing team received accurate data from its digital marketing but lacked tools to measure all marketing with unified and comparable metrics
  • A key objective was to determine the impacts of TV and leaflet advertising on campaigns
  • Secondly, Gigantti sought more insights into how tactical and brand advertising support each other

Solution Outputs

Sellforte’s software calculated the incremental sales and margin uplift that each media group generated, excluding the impact of the offers themselves.

Client testimonial

For me and my team it’s now easier to prove our decisions when we’re having the numbers and hard data behind the decisions. So when I’m going to the board meeting or presenting stuff in the management meeting it’s way easier now because we can really have the grounds.
