DIGIVELL Growth & Tech Labs
5
(3 reviews)
Growth & Tech Lab | Engineering Measurable Commercial Growth
Recommended
DIGIVELL operates as a Growth & Tech Lab rather than a traditional advertising agency. We bridge the gap between engineering, analytics, technical SEO, and performance marketing to turn customer acquisition into predictable, scalable revenue. Operating across Sofia, London, and Istanbul, we partner with ambitious brands to build robust digital infrastructure, optimize conversion funnels, and execute high-ROI acquisition campaigns. What sets us apart: • Integrated Capabilities: Technical development, conversion tracking (server-side tagging, API/payment integrations), SEO architecture, and paid media managed under one roof. • 100% In-House Delivery: We do not outsource our core services. Every audit, campaign, and technical implementation is built and managed by our specialized in-house team. • Dedicated Accountability: A single senior growth lead responsible for direct communication, agile execution, and transparent reporting. • Measurable Commercial Focus: We prioritize qualified acquisition and bottom-line growth over vanity reach metrics. Whether restructuring paid acquisition across Google and Meta, engineering high-converting web platforms, or building international go-to-market positioning, we build systems designed to scale.

Mind Studios

(4 reviews)
Long-Term Technology Partner for Growth-Stage and Mid-Market Companies
Recommended
Founded in 2013, Mind Studios is a custom software development company working with growth-stage and mid-market businesses across the US, UK, Europe, and MENA. The portfolio spans logistics platforms, real estate marketplaces, healthcare systems, and fitness ecosystems - operationally critical products built for companies where technology is central to how the business runs. The team engages at the architecture stage, before the critical decisions get locked in. Business analysis, technical scoping, and honest pushback on briefs that won't hold up at scale are standard. The goal from day one is a system that doesn't need to be rebuilt in two years. What distinguishes Mind Studios is what happens after launch. Scaling infrastructure, iterating on features, extending systems as the business grows - this is where most of the value gets built, and where long-term client relationships form. The average engagement runs over two and a half years. Many go considerably longer. 100+ specialists. 13 years in business. 70% client retention rate.
