Test automation our developers adopted as a tool rather than a compliance burden

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

Project summary

B2B customer churn was concentrated in accounts that rated our self-service portal poorly. A redesign was necessary before the next wave of contract renewals.

Complex project, zero drama. That is how you know the project management is real.

The platform has been live for six months and is handling three times the transaction volume we scoped for. That is not because we underestimated — it is because the architecture choices made during discovery were genuinely forward-thinking. Most vendors design for exactly what you tell them. This team designed for what you are likely to need. We are already scoping the next phase and there was no question about who we would use.

Project summary

Our product thinking was strong. Our execution capacity in this specific domain was limited. We needed deep expertise, not a generalist willing to learn on our time.

Architecture review that saved us from a vendor decision we would have regretted

The platform has been live for six months and is handling three times the transaction volume we scoped for.

This team designed for what you are likely to need. We are already scoping the next phase and there was no question about who we would use.

Project summary

Partner-level reporting required visibility into matter data that our current systems could not provide without significant manual extraction and aggregation.

A vendor that earned a place on our preferred supplier list through delivery, not sales

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

Project summary

Our compliance team had flagged gaps that needed fixing before our next regulatory review. The work was too specialist for our internal team to absorb without dropping the product roadmap entirely.
