AI SaaS & custom software development

AI SaaS and custom software development — web apps, mobile apps, B2B SaaS, and AI SaaS for founders and enterprises worldwide, with security review when buyers require evidence.

What “software build” means here

Block Consulting is not blockchain-only. We design and build web applications, AI SaaS and conventional SaaS, iOS and Android apps, APIs, and internal platforms — then harden them when a CISO, marketplace, or regulator asks for evidence.

Typical buyers: founder-led product companies, developer agencies that need a UK overlay, US startups raising with SOC 2 language in the data room, and UAE teams shipping into VARA, ADGM or DIFC.

Products we build (specific and generic)

Named products we have shipped sit on the AI and blockchain pages. The list below is the wider studio remit — if it is a software product, it is in scope unless we say otherwise on a call.

AI SaaS / LLM SaaS platform

Multi-tenant product you sell: agents, copilots, usage metering, tenant isolation, audit logs.

B2B SaaS (non-AI)

Subscriptions, roles, admin, APIs — CRM, portals, vertical SaaS, workflow SaaS.

White-label or OEM SaaS

Your brand on a platform we engineer; tenants and billing hooks included.

SaaS MVP / seed-stage product

First production version: auth, billing-ready, admin, one core workflow.

Customer-support SaaS / helpdesk AI

Multi-channel chat, RAG over your docs, handoff to humans.

HR / recruitment SaaS

Resume parsing, screening, interview-question generation.

Legal research / knowledge SaaS

RAG over contracts and policy — with logging for EU AI Act paths.

Document intelligence SaaS

Upload, search, extract, Q&A over PDFs and wikis.

Trading / decision-support product

ML signals for crypto or equities — not investment advice.

E-commerce and marketplace apps

Storefronts, agents, and ops consoles.

Fintech web and mobile apps

Onboarding, payments hooks, ledgers — PCI-aware architecture when cards are in scope.

Health-adjacent software (HIPAA-aware)

US health export deals: technical safeguards and evidence notes — not a covered entity or BA by default.

Public websites and landing pages

Marketing sites for the products above.

REST / GraphQL APIs

Public or partner APIs with authZ review.

Frequently asked questions

Can you build an AI SaaS product from scratch?
Yes. Multi-tenant architecture, auth, roles, usage metering, tenant isolation, RAG or agents, admin console, and audit logs. We also produce EU AI Act / SOC 2-oriented engineering evidence when US or EU buyers ask for it.
Do you only do blockchain, or general software too?
General software is in remit: web apps, mobile apps, SaaS, APIs, internal tools, CRMs, fintech, and AI products. Blockchain and smart contracts are one practice alongside that studio.
Can a US or UAE company hire you?
Yes. Contracting is with Block Consulting Ltd (UK). We deliver remotely into US and UAE time zones and scope SOC 2 / HIPAA / PCI or VARA technical evidence when the buyer needs it.
I searched for AI development / AI SaaS / SaaS developers — is that you?
Yes. AI development and SaaS engineering are core studio work: AI SaaS, conventional B2B SaaS, custom software, and mobile apps. Blockchain is additional, not a limit.
