Questions
A working document that tells you — and your co-founder, engineer, or investor — what we'd build, how, by when, and what we explicitly won't build. Agencies normally charge €500–€2,000 to write one. Yours arrives in a few minutes, free, branded, and ready to forward.
Yes, free. No drip funnel, no upsell email. We write your plan because it's the fastest way for both of us to know whether we should work together. If we're a fit, it's the starting point for your build. If not, you walk away with a real working document that helps you go elsewhere.
What you'll have live on Day 28, the specific technical decisions we'd make (data model, auth, payments, integrations), Day 7 pivot review and Day 28 launch milestones, what's in scope, what's deliberately out of scope, the real risks we see in your idea and how we handle them, our three guarantees, and the next step. Around two pages, written in plain language.
It will be honest, not perfect. It reflects what you told us — that's enough for real scope, real technical decisions, and real risks. The 30-minute scoping call on the result page is where we pressure-test assumptions and pick the cadence (Day 28 Live or Day 14 Sprint). Most founders book it after reading the plan.
Your input and the plan are stored in our CRM (Germany-hosted, GDPR-native). We use them to write your plan and prep for the call — nothing else. We don't share them, we don't sell them, we don't add you to a mailing list. Email hello@diepen.io and we delete the record on request.
Then we tell you, and we send you the Founder Validation Playbook instead — a 5-step framework to find the validation signal you need before paying anyone to build. Free, no signup. Come back to /scope when you've worked through a couple of the steps.
Because that's how the work happens. Leander writes the code (25+ shipped products including Handelsblatt, CHECK24, helpcheck). Miraya does the design and reviews UX throughout (26k LinkedIn, 128k Instagram, six years working with founders). The plan you receive is the actual scope we'd execute — not a sales doc. No account managers, no project coordinators, no handoffs.
