How Trustmary Score is calculated
Trustmary Score is an overall assessment of a company's customer experience on a scale of 0–100. It is calculated by combining data from multiple reliable sources through three main components:
The score is based on feedback and reviews from the last 24 months. The more recent the feedback, the more it affects the score.
SATISFACTION
Satisfaction tells how satisfied customers are on average. Recent ratings weigh more than old ones. The average rating of Vainu over the last 24 months is 3.8, based on 71 ratings (feedback or review), of which 55 are identified.
SUCCESS CONFIDENCE
Success confidence tells how consistently the company succeeds. Poor ratings lower the figure even when the average is good. Of the people who rated Vainu, 80.3 % are satisfied (a positive or neutral rating) and 19.7 % are dissatisfied.
FRESHNESS AND VOLUME
Freshness and Volume tell whether the score can be trusted right now meaning if there are enough ratings, and if they are still coming in. Full points are common in this section when the company has enough recent data to evaluate. Days since the newest rating: 7. Ratings in the last 3 months: 14.

Undvik denna dyra tjänsten som kan göras bättre med helt vanlig AI. Det är svårt att få bra resultat om inte man lägger otroligt mycket tid på filtrering m.m. och deras onboarding är minst sagt bristfällig. När man vill säga upp tjänsten så nekar dom om man inte gör det mer än 60 dagar innan den förnyas. De har ingen förståelse för att man kanske bör fokusera på nöjda kunder istället för att fullständigt vägra att vara bemötande.
Vår upplevelse av Vainu har varit fullständigt oacceptabel. Inte nog med att tjänsten enligt oss inte är i närheten av att vara värd pengarna – vi har dessutom fått fakturor som vi anser helt saknar grund och därför har bestridit. Att som kund behöva lägga tid och energi på att hantera fakturor man inte anser sig vara skyldig att betala är under all kritik. Vi har tappat allt förtroende för Vainu och sättet detta har hanterats på. Hade vi vetat innan avtalets start vad vi skulle behöva gå igenom hade vi aldrig blivit kund.
Vi kom överens om att köpa 3 000 leads/exporter för cirka 30 000 kr och testa plattformen i ett år. Vi var tydliga med att vi inte var intresserade av ett löpande system. Automatisk förlängning och fortsatt betalningsskyldighet kommunicerades aldrig tydligt i försäljningsdialogen. När vi senare invände mot fakturan upplevde vi Vainu som i princip omöjliga att ha att göra med. De bemötte inte vad som faktiskt sagts i säljprocessen utan hänvisade återkommande till klausuler i avtalet. Vi upptäckte dessutom inte problemet förrän ärendet redan hade gått vidare till Kronofogden, eftersom fakturan hade skickats till ett inaktivt bolag i vår koncern. Det har orsakat oss onödiga problem och skada i relation till samarbetspartners. Trots detta upplever vi att Vainu vägrar ta ansvar för hur försäljningen och hanteringen gått till. Var extremt noga med bindningstid, automatisk förlängning och uppsägning innan ni skriver på.
