UndSonntag
Systems, execution, and decision-making at the intersection of product and engineering.
I help teams reduce ambiguity, increase shipping velocity, and build operating rhythms that hold under pressure.
How I help
Most teams don’t fail on effort. They fail on structure: unclear goals, fuzzy ownership, weak feedback loops, and decisions made without a model.
Clarity on what to build
Sharper problem framing, deliberate prioritization, and a metric model that survives real tradeoffs.
Execution without fragility
Cadence, interfaces, and quality loops that keep shipping consistent—even under constraints.
Pick what to sell
Narrow to one ICP + one painful job, craft an offer, and define the fastest path to “yes” before you build.
Sell before you build
Proof-first experiments, early pricing, and a simple distribution loop so you’re not guessing in code for 6 months.
Ways I Work
Two modes: de-risk decisions for teams, and de-risk go-to-market for founders.
Clarity Sprint (Product × Engineering)
1–2 weeks
- Turn ambiguity into a decision model: problem, constraints, success metrics
- Expose ownership gaps, decision bottlenecks, and weak feedback loops
- Deliver a prioritized plan with clear owners + checkpoints
Operating Rhythm Setup
2–4 weeks
- Install delivery cadence + rituals that reduce churn and keep shipping consistent
- Definition of done + quality loops (release, QA, incident learnings)
- Decision + execution templates (tradeoffs, RFCs, handoffs)
Wedge & Offer Sprint
1 week
- Narrow to one ICP + one painful job (no “everyone” positioning)
- Craft a clear offer statement + scope boundaries
- Define the fastest path to first “yes” before you build
Validation & Pricing Sprint
1–2 weeks
- Proof-first experiments: what to test, what counts, what to ignore
- Early pricing hypothesis + objection handling
- One repeatable distribution loop to run weekly
Add-On: Technical Product Review
Single session or short series — architecture/product interface review, risk & dependency map, pragmatic recommendations.
