What we stand for
Quoting specialisation
&act does one thing: drafting quotes. The entire platform is built around that.
Inside sales first
Every feature originates in the day-to-day of real inside sales reps, not in strategy workshops.
DACH substance
Hosting in Germany, German tonality, GDPR-compliant out of the box. No Silicon-Valley vocabulary.
Our mission
&act was founded in Munich in 2025 with a simple observation: the German Mittelstand rarely loses deals on the product. Response time decides: 30 minutes per quote, three working days of waiting, while competitors respond in hours.
We have specialised in inside sales for DACH industrial companies and wholesale — specifically quoting. SAP, Dynamics, proALPHA, Salesforce, Sage. PIM, ERP, CRM, Outlook. Variant configuration, discount tiers, customer terms. We build for exactly that day-to-day.
The ambition: to make systematically usable the knowledge that today only lives in the heads of senior colleagues. Without giving IT, data protection or product management a headache.
