Successfully launching a sales prospecting & engagement tool from 0-1 to help sales teams - reduce tool overload and increase revenue opportunities.
For the full director’s cut, I recommend viewing this case study on desktop. The mobile friendly version is streamlined —great for a quick scroll, but the full story plays out best on the big screen.

Cadence is a sales prospecting & engagement platform that enables multi-channel outreach, tracks engagement, and automates workflows through real-time CRM integration. Built for sales teams, its flexibility also suits marketing and staffing use cases.
Designing and shaping Cadence — from early concepts to functional MVP, beta market launch, and finally a growing, stable product.
Clearly it is not easy being on the sales team.
Tools for different actions and communication channel
Different conversations in different channels for different leads
Time-consuming tasks like follow-ups, reminders, and updating CRMs
Data spread across platforms
Identifying the best leads
Managing hundreds or even thousands of leads becomes overwhelming.
Teams still relying on spreadsheets or outdated methods lack a centralized database
Tracking tasks by hand one by one is exhausting and prone to errors.
Without a centralized system, it is difficult to track progress and measure success
Having identified the challenges faced by sales teams we examined popular tools like Outreach.io, Salesloft, and Lemlist which offered some great features, but still left some gaps
First things first, the strengths, things that worked (essentially features that are a must have for tools in this market)Let’s talk about the must haves and the gaps
Channels like videos calls, SMS, Whatsapp, LinkedIn were missing.
Bulky interfaces and enterprise-level focused set-ups made if difficult to navigate.
Extra integrations meant additional fees.
Most platforms don’t bridge the difference between inbound and outbound leads.
Tools weren’t always designed for the unique workflows of every sales team.
The idea that this system can be generalized to be used by teams other than sales.
After having identified the pain points and market gaps the first step into this massive project began with one simple question: How would this tool actually be used?. The initial concept positioned it as a "first touch point tool" for sales teams.
Sales teams aren't one-size-fits-all. They can be structured by roles, geography, product, or channels. To create Cadence, we zeroed in on two critical aspects: roles and lead sources. Using Ringover's sales team as a benchmark, we identified the following :
Sales teams have different sales processes varying depending on the industry, company size, account type, product etc. But a blueprint sales process that almost all sales team would follow is :
By conducting user interviews with various members of the sales team, we were able to develop targeted use cases for specific roles that we could focus on. These conclusions are more focused on the user responsibilities of the role than a user persona, keeping that in mind -
So after the why and the how we began iterating for the designs. Initially we focused on inbound leads. We had roles for Sales reps, managers and company admins. The objective was to give the tool to a select number of users and teams in Ringover and collect feedback on how we could build the tool further.
After nearly a year of rapid iterations and testing, we launched Cadence’s beta to Ringover users, gathering feedback to measure growth and address pain points. Over time, we refined features, improved the experience, and aligned it with Ringover’s brand. Today, Cadence stands strong among sales prospecting tools, thriving with companies that value flexible workflows.
The cadence page is the center piece of our tool (I hope the name doesn’t make it too obvious). Users can create multi step sequences mixing between automated and manual steps for a bulk number of leads. A visually familiar folder structure allows users to keep a tab on all the Cadences created in the company. To launch a new cadence simply create a cadence, add your prospects and launch it. The cadence immediately starts generating tasks for the users associated to the prospects inside the cadence. It helps you cut down on repetitive tasks and keep a track of your progress for each prospect.
So you've probably heard the saying “never judge a book by its cover.” The UI looks good (hopefully) — but does it hold any substance? Let's open this book and recall on all the discussed pain points, market gaps, and feature requests to see how Cadence truly delivers.
1. Multi-channel chaos, tool overload and repetitive tasks
2. Data centralization, lead prioritization, Scaling and traditional systems
3. Tracking, Reporting and analyzing
Cadence started as a first-touchpoint tool and quickly evolved into a full-fledged engagement platform, expanding beyond sales into recruitment and marketing. As a designer, it taught me the value of understanding user pain points deeply. Today, it’s one of Ringover’s fastest-growing, most-used products—driven by continuous feedback and iteration.
Designing Cadence was fun and challenging, especially because it was my first real world project with actual users and tangible impact. Here are some of my learning from this experience :
In design, user feedback is vital—but acting on every request isn’t the goal. Early on, I treated suggestions as mandates, trying to tailor solutions too literally. Through my mistakes I learned the real task is uncovering the core pain points behind those requests. Users focus on their workflows; my job is to see the bigger picture—balancing technical feasibility, product goals, and business value. The key is solving for shared needs without overcomplicating the system or straining development.
As the sole designer, I regularly presented to diverse teams—each with different priorities. I quickly learned that how I present matters just as much as what I present. I learned to tailor my presentations to align with the goals each team wanted to achieve through my designs.
As designers, being able to clearly explain your decisions is crucial—especially in simple, non-technical terms when working with cross-functional teams. I also found that understanding the technical side of other fields makes it easier to communicate ideas and stay aligned. This is even more important with users; by learning about standard sales processes and sales funnels, I could better grasp their workflows and design solutions that truly met their needs.
Collecting feedback is vital, but vague comments like “I don’t like the color” or “Something feels off” often felt subjective and unactionable. My initial instinct was to push back, but I learned that as designers, our role is to ask better questions and extract value. Instead of asking “why,” I started prompting users with comparisons like, “Is there a tool you find intuitive? What works well about it?” This helped uncover real insights and align designs with user expectations.
Always down to chat—about subbed & source material supremacy, cool usability observations, Mark S. & Helly R. hot takes, or a spontaneous Euro trip...... work stuff too, obviously.
