# a11l

> a11l is fractional product leadership for digital products by Alexander Karl, Berlin. He takes a product area off your desk and owns it, two to three days a week inside your team, for scale-ups (Series B+), PE-backed companies and enterprises in DACH and Europe. Products customers love, numbers investors can trust.

Key facts: Fractional Product Lead, not a consultancy and not a coach; hands-on inside the team; in your cadence from week two; weekly written check-in, decision log and release-scoped roadmap in your tools; AI-native delivery (codified workflows, prototypes); goal is a handover to your full-time lead. Not the fit for managing a PM team or finding product-market fit from scratch. Contact: a@a11l.io, +49 157 5312 5112, https://calendly.com/alexanderkarl/30min. Languages: German, English, Russian, Ukrainian.
