Hotjar Experts in Berlin

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.

• Led marketing and corporate communications team (8 FTE) with budget and team responsibility to 250+ clinic customers and 150K patients, managing all aspects of marketing, brand messaging and public relations
• Led development of multi-channel demand gen and partner marketing with Sales and CSM (LinkedIn, webinars, email, field marketing, medical briefings in orthopedics, neurology, long-covid, oncology), achieving +180% leads, +120% webinar signups, +35% MQL conversion
• Architected new PLG/app marketing playbook with Product and Data to streamline and leverage product launches, achieving +150% 5-star app reviews from patients and +10 NPS
• Launched ingredient branding strategy, securing two major clinic chain partnerships and patient testimonials. Led proactive PR media and KOL campaigns (+20% sentiment)
• Introduced MarTech AI for marketing automation and campaign efficiency (SFDC, ActiveCampaign, Plausible, Figma), aligned with Legal on GDPR, PDSG, ISO:27001 compliance

• PROBLEM: GTM effort is guesswork across fragmented identities and channels, with no closed feedback loop.
• BUILT: Cost-pyramid engine (L0–L3): identity resolution across ~25k entities, explainable intent scoring, and a closed decision loop (propose → execute → evaluate → learn) with calibration.
• IMPACT: Shipped v1.3.1 with a live demo; 99% of operations resolve at the free L0 tier (CI-enforced); $0 to run without any API key.
