Full-funnel digital programme that aligned our marketing and sales teams

Jisoo Kwon / CTO - HanRiver Tech Co Ltd
Verified
May 29, 2025

Project summary: Underwriting decisions that should have taken minutes were taking days because of a legacy policy administration system that predated modern API architecture.

The thing I appreciate most in retrospect is that they were honest when something was harder than expected. Twice during the project the team came to us proactively to say that a particular component needed more time to do properly and explained why cutting corners would create problems later. We gave them the time. Both decisions were correct. The resulting product is solid and we have had none of the post-launch instability that plagued our last two technology projects.

PROS

Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project

CONS

We underestimated the internal resource commitment required on our side during discovery — the team warned us, we did not listen fully, and the first sprint was slower as a result

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at HanRiver Tech Co Ltd, a mid-sized organisation in the Insurance sector headquartered in Seoul, South Korea. My remit as CTO covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.
What specific problem or business challenge led you to hire this company?
Growth into new markets had exposed serious limitations in our platform. What had worked for our original user base in Seoul, South Korea was not going to scale internationally, and the Digital Marketing requirements for those new markets were meaningfully different. We needed a partner who had solved that kind of problem before.
What services did the company provide for your project?
Primarily Digital Marketing, though the scope naturally touched adjacent areas. They handled architecture design, implementation, integration with our existing systems, performance testing under realistic load, and knowledge transfer to our internal team. The breadth of what they covered without requiring us to bring in additional vendors was one of the reasons the project ran efficiently.
Why did you choose this company over other providers you considered?
We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in Digital Marketing and specific knowledge of the Insurance sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.
How clearly did the company understand your requirements and business goals?
Extremely well. They asked detailed questions, challenged vague requirements until they were specific, and proposed sensible defaults for decisions we had not yet made rather than just leaving them open. By the time development started there was no ambiguity in the backlog, which is a rare starting position.
How was your overall experience with their communication and project management?
The project management was the best I have experienced in a vendor relationship. We had fortnightly sprint reviews with structured agendas, a shared backlog that we could inspect at any point, a risk register that was actively maintained rather than created at kickoff and never opened again, and a project manager who treated our time as something worth protecting. Communication was proactive, not reactive.
Did the company deliver the project on time and within your expected budget?
Yes. I will note that the original timeline was aggressive and I had privately expected a slip. They managed to hold it by making smart sequencing decisions early on that I only fully understood in retrospect. The budget discipline was equally good — we received a single change request for scope we had introduced ourselves and it was priced fairly.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new Digital Marketing platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The intellectual honesty. They told us when something we wanted was a bad idea and explained why. They told us when a timeline was tight and gave us options. They did not tell us what we wanted to hear in order to win work or avoid a difficult conversation. In a long engagement that kind of relationship is far more valuable than an agency that just says yes.
Would you recommend this company to others, and would you work with them again?
I recommend them to anyone who asks and occasionally to people who do not. The combination of Digital Marketing expertise, Insurance domain knowledge, and delivery discipline is genuinely difficult to find. We found it here and we intend to keep it.

Business intelligence solution that replaced three separate reporting tools

Jordan Mills / Director of Operations - Cascade Manufacturing

Project summary: Our editorial team was managing content across seven different tools with no single source of truth — we needed a unified CMS that could handle structured and rich-media content equally well.

The technical quality of the work is the easiest thing to praise, but what I want to highlight is the communication culture on this team. Every question got a same-day response. Every risk got flagged before it became an issue. When we needed to change direction mid-project — a business decision on our side — they absorbed the change professionally, requoted fairly, and kept momentum going. That flexibility is something you cannot assess in a proposal and it turned out to be one of the most valuable things about working with them.

PROS

Architectural decisions that will serve us for years rather than just solving the immediate problem, knowledge transfer that left our team genuinely capable, no scope creep at all

CONS

We underestimated the internal resource commitment required on our side during discovery — the team warned us, we did not listen fully, and the first sprint was slower as a result

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Cascade Manufacturing, a mid-sized organisation in the Media & Entertainment sector headquartered in Seattle, USA. My remit as Director of Operations covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.
What specific problem or business challenge led you to hire this company?
The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the Data & Analytics expertise to address it properly. We needed specialists.
What services did the company provide for your project?
The full Data & Analytics lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.
Why did you choose this company over other providers you considered?
A direct referral from a peer who had used them for a comparable Data & Analytics engagement in the Media & Entertainment space. That peer's experience had been excellent and their project profile was similar enough to ours that the recommendation carried real weight. Everything we found during our own evaluation reinforced that this was the right decision.
How clearly did the company understand your requirements and business goals?
Extremely well. They asked detailed questions, challenged vague requirements until they were specific, and proposed sensible defaults for decisions we had not yet made rather than just leaving them open. By the time development started there was no ambiguity in the backlog, which is a rare starting position.
How was your overall experience with their communication and project management?
Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.
Did the company deliver the project on time and within your expected budget?
Yes on both counts. There was one sprint where a third-party integration took longer than scoped because of undocumented API behaviour on the vendor side. The team flagged it immediately, proposed two mitigation options, and we agreed on an approach that recovered the timeline within two weeks. That is how scope issues should be handled and rarely are.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new Data & Analytics platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The continuity of the team. The engineers who scoped the work were the engineers who built it. That sounds like it should be standard practice but in my experience it often is not. The institutional knowledge that comes from that continuity pays dividends at every stage, particularly when you are dealing with a complex Media & Entertainment domain where context takes time to build.
Would you recommend this company to others, and would you work with them again?
Yes, without qualification. I have already made two direct referrals to peers in the Media & Entertainment sector who were facing similar Data & Analytics challenges. In both cases I gave the recommendation specifically because I was confident the experience would match what I described — which is a level of confidence I do not extend lightly.
