Web development for SaaS, Web3 and product teams

Senior product design, engineering and launch support

Flat 18 is a senior web development studio for teams building or improving digital products. We combine product design, full-stack engineering, integrations and launch support, with LLMs used carefully to speed up the right work.

When a product team needs a delivery partner

  • You need one accountable team for UX, UI and full-stack delivery
  • An MVP or internal product needs a reliable route to launch
  • A half-built product needs clearer scope, stronger engineering and fewer hand-offs
  • Performance, accessibility, integrations or maintenance are holding the product back

What we can take on

We can take a product from concept to launch, or take over a partly built service and give it a clearer, safer path forward.

  • Product discovery, UX and interface design
  • Frontend, backend, APIs, authentication and data layers
  • Third-party integrations, deployment and release planning
  • Performance, accessibility, security and maintainability reviews
  • Documentation, handover and ongoing development support

How delivery stays on track

  1. Frame: agree the product goal, users, constraints and delivery risks.
  2. Plan: turn the work into clear milestones, prototypes and technical decisions.
  3. Build: deliver in small reviewable increments with senior engineering oversight.
  4. Harden: test the product, tighten performance and document the important decisions.
  5. Launch: deploy, monitor and hand over with a clear support plan.
