• In just one month, DevsData LLC helped ListKit hire four niche technical experts across Europe with a tailored recruitment strategy.
• This case study shows how DevsData LLC navigated a complex talent market and refined role definitions to unlock top-tier candidates for a fast-growing B2B data platform.

Introduction

ListKit, a company specializing in email infrastructure and deliverability systems, partnered with DevsData LLC to expand its technical team. The collaboration focused on building a specialized team to support the company’s core operations.

As a leading B2B data provider, ListKit helps businesses build hyper-targeted contact lists without the need for manual verification. Its expansive database of over 500 million triple-verified leads powers omnichannel cold outreach, enabling sales teams to launch more effective email and cold call campaigns.

With a user-friendly platform, a strong emphasis on data integrity and privacy, ListKit simplifies the lead acquisition process. In 2024, the company generated $2.6 million in revenue, and today it supports over 1500 companies in creating meaningful connections and reaching ambitious growth targets. To handle its next stage of growth, the company decided to increase its team, adding four engineers with DevsData LLC’s support.

Project summary

ListKit needed to broaden its internal expertise to reinforce its email infrastructure and day-to-day operations. Adding four more engineers was a major step for a company of its size, as it considerably increased its technical capacity. The new hires were expected to bring strong skills in backend systems and email deliverability while fitting well with ListKit’s remote-first way of working.

Through the support of DevsData LLC, ListKit successfully hired four key team members:

• Two Backend Developers to enhance the architecture and performance of its email systems,
• One Email Postmaster to monitor and maintain high deliverability and sender reputation
• One Email Operations Manager to optimize workflows and drive consistent campaign execution.

The recruitment spanned multiple European countries and required careful adjustment of compensation to diverse market conditions. It also demanded a tailored approach to identifying candidates.

Challenge

The recruitment process faced a significant hurdle due to the particular job titles in ListKit’s initial job descriptions. These titles were tailored to the company’s internal terminology, which limited the candidate pool since they did not align with standard industry roles. For smaller companies, especially, using widely recognized job titles is often more effective, as it broadens visibility and helps candidates quickly understand the requirements.

Additionally, the search covered several European countries, each with its own talent market dynamics, salary expectations, and legal frameworks. This geographic spread introduced further complexity, requiring a flexible and localized approach to candidate sourcing and evaluation.

DevsData LLC’s approach

DevsData LLC employed a meticulous approach to overcome the recruitment challenges, ensuring a tailored and efficient process:

1. Job title analysis and optimization

DevsData LLC found that ListKit’s original job titles were overly specialized, which significantly narrowed the candidate pool. To address this, the recruitment team conducted a thorough analysis of industry-standard terminology using platforms like LinkedIn and Stack Overflow. This process helped uncover widely recognized job titles that accurately reflected the required skills and responsibilities, broadening the appeal to qualified candidates without compromising the expertise needed.

2. Strategic geographical focus

ListKit was open to expanding its team beyond its home market, which made it possible for DevsData LLC to search across several European countries. The decision was driven by the need to access a wider pool of engineers with specialized expertise in backend systems and email deliverability, while also balancing compensation levels with company resources.

After reviewing talent availability and market data (including Glassdoor, Payscale, and local recruitment portals), DevsData LLC concentrated its efforts on Serbia, Romania, Estonia, and Hungary. Serbia and Romania provided broad access to skilled backend developers, while Estonia and Hungary stood out for their innovative tech communities and high English proficiency. Since these hires would join a US-based core team, DevsData LLC also considered time zone overlap and candidates’ ability to collaborate effectively in a distributed setup.

3. Streamlined communication and collaboration

DevsData LLC maintained a transparent and responsive communication channel with ListKit. Weekly progress updates and detailed candidate profiles ensured that ListKit’s feedback was quickly incorporated. This iterative process allowed DevsData LLC to refine candidate shortlists promptly, avoiding the common pitfall of prolonged profile reviews. The agency also used structured interview frameworks to align with ListKit’s expectations for technical skills and for working productively with colleagues across different regions.

4. Comprehensive candidate vetting

Candidates underwent a rigorous screening process to ensure alignment with ListKit’s needs. For Backend Developers, DevsData LLC assessed proficiency in technologies like Python, Node.js, and email protocols (e.g., SMTP, DMARC). The Email Postmaster candidates were evaluated for experience with email server management tools and compliance frameworks, while the Email Operations Manager candidates were screened for operational expertise and data-driven decision-making. Technical assessments, including coding tests and scenario-based questions, were complemented by behavioral interviews to confirm alignment with ListKit’s distributed team setup.

5. Localized salary benchmarking

Balancing ListKit’s budget constraints with diverse market expectations, DevsData LLC conducted detailed research to benchmark fair compensation in each target country. The earlier selection of Serbia, Romania, Estonia, and Hungary was not only based on talent availability and skills, but also on cost-effectiveness relative to ListKit’s financial framework. By aligning hiring geographies with budget realities, DevsData LLC structured compensation so that offers remained competitive for local candidates while staying sustainable for the company. For example, salary packages in Estonia were adjusted to reflect its higher cost of living compared to Romania, while still fitting within ListKit’s overall limits. This approach reinforced fairness, competitiveness, and cost-effectiveness across different markets.

Results

DevsData LLC successfully completed the recruitment project within one month, filling all four specialized roles with qualified professionals. The final hires included:

• Two Backend Developers with expertise in email infrastructure and system optimization
• One Email Postmaster focused on server reputation, compliance, and deliverability
• One Email Operations Manager responsible for campaign performance and workflow efficiency

A key contributor to the project’s success was the refinement of job titles early in the process, which helped align the roles with standard industry terminology and increased candidate visibility.

Combined with a streamlined recruitment strategy and well-defined role descriptions, this refinement enabled DevsData LLC to accelerate the hiring process and successfully fill all positions.

Business impact

With all four roles filled within a month, ListKit quickly strengthened its internal capabilities in email infrastructure, deliverability management, and operational execution.

The newly formed team contributed to faster implementation of system improvements, more reliable campaign performance, and enhanced control over sender reputation, which are key pillars of ListKit’s offering as a leading B2B data provider. This recruitment effort helped ListKit continue its growth while serving an expanding client base.

The case highlights how DevsData LLC delivered highly specialized technical talent rapidly across multiple markets.
