SumatoSoft provides software development services such as software creation, function development, and models. They currently collaborate with in-house staff on a large project for a major third-party client.
SumatoSoft’s efforts have helped bolster development speed and increase customer satisfaction. They are a young, active, and energetic team, and provide valuable education that has resulted in more knowledgeable employees. They are professional and experienced in Ruby development.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Please describe your company.
Our company is involved in the automobile industry in Russia. We developed an ERP [enterprise resource planning] system – like a DMS [dealer management system]. It’s a system that automates automotive dealer operations.
What is your role and responsibilities?
I am the general director.
OPPORTUNITY / CHALLENGE
What was your goal for working with SumatoSoft?
We were operating for about one and a half years before we started the engagement. SumatoSoft helped to boost our speed of development. Their role was outsourcing a team. We have our team, but it was not enough capacity.
SOLUTION
Please describe the scope of their work.
Their work is all software development. They helped us to develop software. It had a warranty. Part of the team was from SumatoSoft and the other part was our own internal development group, so they developed some functions and models for us.
What was your process for selecting SumatoSoft with which to work?
I have just a positive impression. I knew these guys previously before they became SumatoSoft, and I know them as good professionals. When they organized their own company, we signed a contract with them and started with them. They continue to work with our company.
Can you provide a ballpark dollar figure for the size of the work that they’ve done for you?
It’s a big project worth about approximately 3 million rubles per month, so around $100,000 per month. It is very large and our main customer is a very big dealer group on the Russian market.
RESULTS & FEEDBACK
What were the results of the project?
This is ongoing work. We have some deadlines. Part of this system is already in production. It’s a CRA model that is already in production, and now we are working on a service and spare parts model. We will launch it in the middle of 2015. After that, we will develop other support. Everything is successful with their work and I’m satisfied with their work.
Do you have any statistics or metrics to track improvement from the project?
Our main KPI [key performance indicators] is the happiness of our customers. Of course, we have some details. We are using a system to account our operating productivity, like the number of hours, points, and stuff like that, but it is internal information.
Is there anything unique about SumatoSoft really makes them stand out, compared to other companies?
They are a very young company and very strong and active guys. Very energetic is a better phrase. They can operate very proactively, by not only paper or contract, but also just listening to what the customer wants. Firstly, they try to satisfy us and they’re very professional with Ruby development. We use Ruby. They’re very good professionals. Many members of our team just started and got experience from SumatoSoft. They also help us to develop our people.
Looking back on the work so far, is there any area that you think they could improve upon or something that you might do differently?
They are really quite good. I think that when they grow up, maybe it will be necessary to make some organizational changes for common things and questions as companies grow, but currently, we are satisfied.

Describe the scope of work in detail. Please include a summary of key deliverables.
First, we engaged in approximately 5 informative calls to share our concept and seek SumatoSoft's expert advice on its feasibility. They not only confirmed its technical viability but also presented a clear solution vision that aligned with our objectives. SumatoSoft also provided a concise overview of the bias detection mechanism, and we established the methods for identifying bias within our company. We were satisfied with the outcomes and proceeded to the next steps. The next phase involved a comprehensive discovery process. SumatoSoft's business analyst interviewed six individuals from different departments within our organization, including administration, project management, and human resource management. Much of the effort was devoted to preparing data for AI model training. This involved leveraging datasets from our partner research organizations, acquiring data from HR companies, and gathering in-house data. Additionally, the business analyst described integration methods with HRM platforms through RESTful APIs and designed the dashboard for HR professionals to access. During the development phase, they put the majority of efforts into the:
Natural language processing implementation - NLP was employed to meticulously analyze text-based content, such as job descriptions and performance reviews, for subtle language cues indicative of bias.
Integration with HRM systems - they integrated the solution with the three most widely-used HRM systems.
User-friendly dashboard - they designed a user-friendly dashboard for HR departments with insights from analysis and recommendations. The testing was complicated. They integrated the solution into our HRM system to evaluate its real-world effectiveness.
The results were impressive, with the platform successfully identifying instances of unconscious bias within our recruitment and talent management processes, spanning job descriptions, interview practices, and performance evaluations. Key deliverables: AI-powered bias detection mechanism Product vision Web SaaS solution that integrates with HRM platforms User-friendly dashboard for HR professionals Test plan and test cases Technical documentation
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
We made a notable improvement in the recruitment process, with redesigned job descriptions and interview guidelines. We also observed a more diverse pool of applicants and successful hires.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
SumatoSoft's project management was commendable. They consistently delivered items on time, meeting project milestones as planned. Moreover, their responsiveness to our needs was exceptional. They were proactive in addressing any concerns or adjustments required throughout the project.
What was your primary form of communication with SumatoSoft?
Email or Messaging App
What did you find most impressive or unique about this company?
From the early stages of the project, SumatoSoft demonstrated a proactive attitude, actively seeking opportunities to enhance the solution and anticipate our needs.

This proactiveness greatly contributed to the project's success and exceeded our expectations.
Are there any areas for improvement or something SumatoSoft could have done differently?
