Frequently Asked Questions (Startup MVP Development)
Transparent answers on pricing, timelines, technology, and engineering handover.
How much does it cost to build a seed-stage MVP in London with Xharvoc?
A fixed-scope, production-ready MVP delivered within 8 to 10 weeks typically ranges between £15,000 and £35,000 depending on complexity, third-party integrations (e.g. Open Banking, Stripe, AI pipelines), and data governance requirements. We provide fixed-price milestone contracts so you never encounter surprise billing.
Do we own 100% of the intellectual property and code?
Yes, completely. Under our London corporate engineering contracts, all custom source code, database architectures, API schemas, and deployment configurations are 100% assigned to your company upon milestone completion. We enforce zero vendor lock-in.
Why should we choose Xharvoc over hiring full-time engineers in London?
In London, hiring a senior full-stack engineer takes an average of 45 to 60 days, plus recruiter fees of 15–20% and base salaries exceeding £95,000–£120,000. Xharvoc deploys an experienced, senior engineering squad immediately under the direction of an experienced systems architect, delivering your live product in 8 weeks at half the initial capital outlay.
What technical stack do you recommend for high-growth MVPs in 2027?
We engineer modern MVPs using React, Next.js / TanStack, TypeScript, Supabase (PostgreSQL), and Cloudflare Edge Workers. This stack guarantees sub-200ms latency globally, zero cold-starts, robust role-based security, and near-zero server infrastructure costs during early customer validation.
Can our product pass investor technical due diligence?
Yes. Every line of code is structured to pass rigorous VC and angel investor technical scrutiny: clean TypeScript typing, automated migrations, modular microservice architecture, strict UK GDPR compliance logging, and ISO 27001:2022-aligned data governance controls.
