Three ways to move important software forward.

Design, engineering and infrastructure stay connected throughout the engagement, with Pius accountable for the complete result.

  2. 02

    Modernise or rescue a platform

    Stabilisation, architectural improvement and progressive modernisation for systems that support revenue or operations.

  3. 03

    Provide senior technical direction

    Discovery, architecture, audits, technical roadmaps, due diligence and embedded CTO-level guidance.

We focus on the hardest part.

Senior-led from discovery to launch and support.

A compact delivery model with direct accountability, specialist expertise and decisions your team can maintain.

  1. 01

    Understand the constraint

    We map commercial priorities, users, inherited systems and delivery risks before choosing an approach.

  2. 02

    Design the product and architecture together

    We consider visual identity, interaction, data, integrations and infrastructure as parts of the same system.

  3. 03

    Build for the team that inherits it

    Clear boundaries, documentation, observability and support make the work easier to operate after launch.

What clients say.

Approved reflections from the people responsible for the work.

“Pius challenged a few of our early assumptions, which improved the product considerably. The work stayed commercially focused throughout and the final system has become an important part of the business.”

Chief Executive Officer, UK technology companyFounder and client

“The technical judgement was consistently strong. Trade-offs were explained clearly, difficult problems were handled properly and the implementation felt considered rather than rushed.”

Chief Technology Officer, Software companyTechnical lead

“Communication was direct and dependable. We always knew what was happening, decisions were made quickly and we never felt passed between different people.”

Founder, Venture-backed startupProduct owner

We help agencies deliver ambitious ideas.

Pius can join a pitch, test feasibility, rescue a difficult build or own the technical delivery behind the scenes.
