AI Agent SaaS

Founded and built an AI agent SaaS for automated customer support and lead qualification, including implementation with pilot customers.

• Service → product transformation: productization from the agency into an independent AI agent SaaS. The starting point was a specific customer problem; the product was developed together with the customer.
• Developed and launched AI agents for website inbound, lead qualification, and customer service, reaching €8K MRR.
• Structured and led a remote team across engineering, LLM ops, and customer enablement.
• Case PTC Auto (e-commerce on Shopify): connected an AI support agent to the store, automated product data & support workflows, reducing workload by ~10–15 hours per week per support employee.
• Set up GDPR-compliant data processing for the AI agents: data processing agreements, deletion policies, and customer data storage locations.
• Assessed agents against the EU AI Act (risk class, transparency requirements) and built them accordingly.
• Addressed customers’ compliance and security requirements (questionnaires, evidence, contracts) to make sales possible in the first place.
• Built technical safeguards into the product to prevent agent misbehavior: hallucinations, escalation to humans, and logging.

Workflow-automation SaaS for operations teams (Berlin, 120 people); full-time freelance engagement reporting to the CEO: an initial 12-month interim mandate, extended twice through the AI build-out; owned product for one squad and coached the other product managers on process.

• Led generative AI (LLM) integration into the core product: from LLM-powered steps to natural-language workflow authoring and step-level automation suggestions, plus AI-managed dynamic workflows, shipped behind eval gates with human-in-the-loop fallbacks: AI-drafted workflows grew to 31% of all new workflows, and median time-to-first-workflow fell from 3 days to 4 hours.
• Packaged the AI capabilities as a usage-based add-on priced on executed automation steps, working with sales and marketing on positioning: ~€800K added ARR in the first year, and adopting accounts churned 1.8 pp less.
• Owned the roadmap end to end: replaced feature-request-driven quarterly planning with an outcome-based rolling roadmap built on quarterly bets and explicit kill criteria, presented monthly to the executive team and quarterly to the board.
• Rebuilt the product-management operating system: weekly customer-discovery cadence incl. workshop facilitation, RFC/decision-doc reviews and a single quarterly metrics narrative; coached four product managers, one promoted to senior during the engagement.
• Closed the engagement as scoped: hired and onboarded the permanent VP Product, handed over the process playbook and roadmap, and exited on schedule in June 2026.
