Senior Software Engineer

About Agaton

Agaton is the leading deep voice AI platform for enterprise sales and customer service teams. Our proprietary technology analyses every customer conversation, not just what's said but how it's said, surfacing the buying signals, unmet needs and churn risks in calls companies already make. We turn that into better conversations, making both human and AI agents measurably stronger, so teams drive more sales, stronger retention and higher quality.

Founded in 2024 by Andreas Kullberg and John Kristensen, Agaton has offices in Stockholm and New York, serving global brands such as Telenor, Axo Group, Telia, AIG and Tele2. The Agaton team previously held key positions at Google, Spotify, Salesforce, Slack and Tink.

Agaton is backed by Inception Fund, Alstin Capital and Sequoia Capital Scout Fund, alongside angels including Silo AI founder Peter Sarlin, HubSpot's Kieran Flanagan and King co-founder Sebastian Knutsson.
