Behind sip.coach stands ESTAYA Beyond GmbH, a German software company. We build AI sales training that sales organisations can trust: conversation quality is never a gut call here, it is measurable, comparable, and auditable. Developed and hosted in Germany.

The idea and methodological framework behind sip.coach originated with Roland Hölscher. Based on the initial prototype developed by Roland Hölscher and Ron Autenrieb, the concept is being refined into a market-ready enterprise platform in collaboration with ESTAYA Beyond GmbH.
Christopher Blaschke studied mathematics, physics, law, and business administration. He previously co-founded and managed an AI software company with offices in Leipzig, Frankfurt, and Prague, advising DAX corporations and mid-sized enterprises on digitization, automation, and AI. At ESTAYA Beyond, he oversees the technology architecture and product development for the sip.coach platform.

Sales reps practice with AI conversation partners that respond like real customers. Every conversation is evaluated across 5 dimensions and condensed into a deterministically aggregated overall score (3 scoring runs, median, reported scoring spread). The result is development that remains fully traceable.
They shape every product decision: from the scoring algorithm to the server location.
Subjective coaching feedback does not scale and does not compare. That is why we condense the AI evaluation into a deterministically aggregated overall score with self-consistency assessment (3 scoring runs, median, reported scoring spread): traceable and reproducible: a shared language for conversation quality.
Sales conversations contain sensitive business and personal data. We store data in the EU; certain processing steps (voice AI) are handled by carefully selected data processors, secured through data processing agreements and EU Standard Contractual Clauses. We comply with GDPR Art. 15 & 17, are aligned with the EU AI Act and report in aggregated, works-council-friendly form, without individual monitoring.
Our training is grounded in established sales methodologies: needs-discovery questioning (Situation · Problem · Implication · Payoff), qualification frameworks, pain-first selling, insight-led selling, solution-focused selling, budget & decision check. No invented frameworks, no buzzwords. Substance, not hype.
For German insurers, banks, and healthcare organisations, auditable data handling is not a nice-to-have. It is a procurement requirement. We built sip.coach with that in mind from day one.
A platform of six modules: with the breadth that real training demands.
We build sip.coach so that the overall score is deterministically aggregated and fully traceable, and that German data storage remains transparent, so that works councils and compliance teams are brought along from day one.
sip.coach grew out of a simple observation: sales teams do not practise enough, because real practice is expensive, awkward, and hard to measure. We change that.
No two managers evaluate every step of a conversation the same way. Role plays with colleagues practise the game, not the customer. An objective benchmark was missing.
The AI evaluates the dimensions; aggregation into the overall score is deterministic: with self-consistency assessment (3 scoring runs, median, reported scoring spread), transparent and verifiable for compliance and works councils.
Data sovereignty was not bolted on afterwards. German data storage, secured data processing, GDPR Art. 15/17, and alignment with the EU AI Act are part of the architecture, not the marketing.
