5(12 reviews)Profitable Amazon and DTC growth, run by senior specialists daily.
Olifant Digital is a full-service Amazon agency and Amazon PPC agency managing $100M+ in annual Amazon client revenue across 50+ accounts. Founded in 2018, the agency works with established brands across the US, UK, and EU, providing Amazon PPC management, SEO, listing optimization, A+ content, catalog operations, and product launches as one integrated system. All accounts are managed exclusively by senior Amazon specialists with 7+ years of experience, with no junior account managers involved. This senior-only model is a key differentiator in the Amazon agency space. Olifant Digital uses a TACoS-first PPC methodology focused on total Amazon profitability rather than ad-attributed ROAS alone. Its 1-1-1-1 campaign structure (one campaign per ASIN, match type, ad type, and targeting group) enables precise SKU-level control and removes data blending. PPC is fully integrated with conversion and operational optimization. Listing SEO, A/B-tested creative, A+ content, profitability tracking, inventory oversight, and account health monitoring all run alongside campaign management to ensure scalable performance. The agency also operates Olifant AI, a proprietary Amazon PPC and account management platform that tracks keyword rankings, indexation, listing quality signals, and SEO performance daily, enabling fast optimization before issues impact revenue. Olifant Digital has 30+ published case studies with verified results, including: • Ekster — $688,406 added annual profitability • WedgeGuys — +$305,771 monthly revenue, 17% lower ACoS • Elite Jumps — +124% monthly revenue in 3 months • MatchaBar — +$114,305 monthly revenue increase • Balanced Tiger — +171% monthly revenue, 50% lower ACoS Every engagement includes a 60-day money-back guarantee if results do not improve.

5(3 reviews)Software built at the frontier of what's now possible.
RecommendedTake Off Labs is an AI-native software studio. We design, build, host and maintain products end to end, with AI woven through the process rather than bolted on at the end. Fourteen years of shipping, more than a hundred companies, across healthcare, fintech, e-commerce, real estate, logistics and maritime. We also build and run our own products, Doc2Data.io for document AI and Microsites.AI, which means the architecture decisions we recommend are ones we live with ourselves. How we work: prototypes that map real user journeys, AI-augmented build from the first commit, deployment on our own pipelines, error tracking and monitoring wired in from day one, and continuous improvement after launch. One studio owns the whole lifecycle, so nothing falls between teams. We scope with our own tooling and commit to fixed prices that hold. When scope changes, it goes through a formal change request rather than quietly appearing on an invoice.

UASOFTDEV is a founder-led staff augmentation of AI-Ready Dedicated Teams and Senior Software Engineers for small-mid companies. We believe AI doesn't replace experienced engineers. It makes the right engineers dramatically more effective. That's why every developer we provide uses AI as part of their daily workflow with tools like Claude, Cursor and GitHub Copilot, while all architecture, technical decisions, code reviews and production releases remain under experienced human ownership. Main engagement models. Staff Augmentation for companies looking to extend their existing engineering team with senior talent, and AI-Ready Dedicated Teams for businesses that need a complete delivery team with technical leadership capable of owning products, features or entire engineering initiatives. Every engagement is led directly by our Founders. Aleksey, CEO, works closely with clients to understand product goals, business priorities and team dynamics. Oleksandr, CTO, personally evaluates every engineer for technical excellence, communication and problem-solving skills. Our work is built around four core values: quality, clarity, transparency and a personalized approach to every client engagement. The process is simple: after a discovery call, we match engineers to your technology stack, product domain and culture, present a CTO-vetted shortlist and run contracting alongside onboarding. Staffing typically happens within 60 hours. Today, our teams support startups and product companies across Europe, UK and North America. UASOFTDEV's track record includes a 97% first-candidate acceptance rate, a 95.65% first-match success rate and an average client engagement of over 13 months.
