The history of Dialectica

Although the founders have a background at Alphasights, buyside firms and Goldman Sachs, Dialectica is particularly strong with consulting firms. It is mostly focused on serving clients in Europe from its office in Athens.

Aside from standard phone consultations with experts, Dialectica also offers to engage its advisors for longer-term assignments and can produce written deliverables such as surveys and reports upon request.

Dialectica closest competitors in the European consulting segment include Guidepoint, Prosapient, Focal Fact, and Atheneum.

In 2023, Dialectica saw an exodus of senior leaders including the CFO, Product VP, and the respective Heads of all regions (EMEA, APAC, North America, and LatAm). The previous year, Dialectica had written in its annual report:

Also in 2023, Dialectica alumni started two new expert networks:

Both firms have grown rapidly in their first year in business, in partnership with Inex One. This is attractive to clients, as they offer a high-quality service at more attractive economics. This is nothing new. Dialectica took Alphasight's high-end service model (high-quality HR practices in hiring, training and retention of staff) out of high-cost London to lower-cost Athens. They could higher top-talent at a fraction of the cost of London, and apply more resources to every project. This was a successful model. But Athens is now getting crowded with large offices from competitors such as Guidepoint and GLG. The competition further intensified in Q4 2023, as Guidepoint terminated its 60+ employee Düsseldorf office, moving all European operations to Athens.

Infoquest and Reticula are applying a similar business model, but operating their high-end service model from even lower-cost locations in Türkiye and Lebanon.
