Founded by Gianmarco Giordaniello, Official Member of the Forbes Business Council, Prisma House builds the CRMs, client portals and websites growing companies run on, and starts every build from the strategy.
-- LONDON, UNITED KINGDOM, 23 October 2026 — Prisma House, a London-based studio that builds custom CRMs, business systems and websites for growing companies, today launched its new website, prisma-house.com. The studio designs software around how a company actually works, and starts every project from the marketing strategy rather than from a template.
Prisma House was founded by Gianmarco Giordaniello, Founder and CEO and an Official Member of the Forbes Business Council 2026. He started it after building and running his own media and publishing businesses, along with the CRM, platforms and websites they run on.
"Most growing companies run on software built for someone else's business. They pay per seat for a CRM their team works around, and for a website designed before anyone decided what it should sell," said Gianmarco Giordaniello, Founder and CEO of Prisma House. "We shape the strategy, then we build it, and the client owns every line."
What Prisma House buildsCustom CRMs and back-office systems, client portals, websites and website redesigns, content management systems, SaaS products, and AI agents that take over repetitive operational work. Examples with real screens are available at prisma-house.com/work.
How engagements startMost projects begin with the Strategy & Scoping Sprint: two weeks, fixed price. Prisma House maps how the business works, defines what to build and why, and delivers a scoped plan with a clear budget, including an honest recommendation when off-the-shelf software is the better choice. Clients own everything that is built: code, data, hosting and documentation.

When should a company build a custom CRM instead of using HubSpot or Salesforce? When its process is genuinely unusual, when per-seat licences grow faster than the value they deliver, or when the team works in spreadsheets around the tool. If a standard CRM fits, Prisma House recommends using it.
Who owns the software Prisma House builds? The client: code, data and hosting.
