The full answer
Senior-only teams change how a project feels. Fewer decisions need to be escalated, architecture choices are made with an eye on how the product will grow, and problems are raised early rather than discovered late in testing.
Every project has a named engineering lead. That person joins discovery, shapes the technical architecture, runs the two-week sprint cycle and is your main contact throughout. You always know who is responsible and who to speak to.
Seniority also matters for quality. Creuto builds with secure coding practices aligned to OWASP, automated testing as part of QA, and vulnerability assessment and penetration testing before major releases. Experienced engineers apply these habits by default rather than as an afterthought.
This approach is part of the company standard, "Either we build it exceptional, or we don't." It is one reason 99% of Creuto's clients rate it top marks.
When you compare software companies, ask who will actually write the code after the contract is signed. At Creuto the answer is set out in the fixed-scope proposal, which describes the team for your project, and you meet your engineering lead before work starts, so there is no gap between the people who pitch and the people who build.
