About StartupCookie

Big-agency output. Two people. On purpose.

StartupCookie is an AI-native content & GTM agency for B2B SaaS. Co-founders Barbara Jovanovic and Sam Claassen run every engagement themselves. Custom AI agents handle the production work, so two senior people can ship what a full team normally does.

How we work

Agents do the production. Humans do the judgment.

Barbara and Sam run every engagement themselves. Two senior people, a deliberate client cap, and no layers in between.

AI-native by design

We build custom agents that handle the repeatable production work. That leverage is how two people ship the output of a full content team, without hiring one.

Senior-only, no account managers

Every strategy call, edit, and decision comes from a co-founder. Nothing gets handed off to a junior team, because there is no junior team.

Maximum six clients at a time

We cap the roster at six clients. The cap keeps both co-founders close to every account, and it is why the model works.

Simple terms

You can stop any month, with no long-term commitment. Onboarding takes 2 weeks from kickoff to first published asset. You give 1-2 hours per week of input, and programs compound in 90-120 days.
