Why European founders choose Kilobyte
01
GDPR-native from V1
Consent, DSRs, data mapping and privacy-by-design baked in — not a compliance sprint after Series A.
02
Multi-market by default
i18n, multi-currency and VAT-aware billing so you can expand from Berlin to Barcelona without a rewrite.
03
CET business hours
Real time-zone overlap with your London, Berlin or Paris team — no async 12-hour lag.
04
Investor-ready polish
Design and demo flows tuned for Index, Atomico, Accel — the aesthetic bar European VCs expect.
From idea to funded, launched product — in one squad
MVP in 10 weeks
A shippable, investor-ready MVP built by a senior product + design + engineering squad — not a junior body-shop.
Fundraise-ready product
Design polish, demo flows and metrics that make VCs lean forward on the first call.
Founding CTO support
Fractional CTO, hiring plans and technical DD support until you bring engineering in-house.
Global-ready architecture
Multi-region, multi-currency and localisation-ready from day one — expand without a rewrite.
AI-native by default
LLM copilots, embeddings and evals wired in from V1 — not a feature added six months later.
Growth engineering
A/B tests, analytics, SEO and referral loops so PMF is a metric, not a gut feeling.

International startup FAQs
Most 10-week MVPs land between USD 60K–120K depending on scope. We give a fixed-price quote after a paid discovery week.
For select early-stage rounds we blend cash + equity. It is opt-in on both sides, never a default.
You do. 100% assignment on every deliverable, transferred at each milestone.
