How LeanMarketing Scaled to 27 Crypto Clients and $1.04M Monthly Ad Spend with Blockchain-Ads

Scale a high-margin crypto agency practice across DeFi, CEX, and blockchain verticals
LeanMarketing is an ROI-focused performance marketing agency specialising in the DeFi, CeFi, and blockchain verticals. The agency operates a lean, high-margin model built around cost-efficiency and consistent client performance. Over four years as a Blockchain-Ads partner, LeanMarketing has grown its client roster to 27 active accounts. These accounts are running 97 campaigns across crypto exchanges, DeFi protocols, and Layer 1 blockchain brands. The agency prioritises transparent reporting and full-funnel campaign architecture across its entire client portfolio.
Attribution Note: LeanMarketing operates as a direct partner on Blockchain-Ads, managing campaigns across multiple client accounts from a single platform. This case study documents LeanMarketing's partner program experience and illustrates the results agencies can achieve when running restricted-vertical client campaigns through Blockchain-Ads. Individual agency outcomes will vary based on client vertical mix, managed spend volume, and campaign structure.
LeanMarketing needed a platform that could deliver consistent, measurable results across restricted crypto verticals for a growing roster of clients. All without the policy friction and targeting limitations of mainstream ad platforms.
Four obstacles defined what that required:
Mainstream platforms do not allow crypto advertising in the verticals LeanMarketing's clients operate in. Google and Meta restrict token launches, DeFi protocols, and crypto exchange advertising in most jurisdictions. LeanMarketing needed a platform purpose-built for the crypto and blockchain space that could handle the full scope of its client portfolio under a single partner agreement.
Blockchain-Ads provided the platform and commercial structure the agency required through four capabilities:
LeanMarketing builds campaigns from awareness through to conversion for each client, using Blockchain-Ads' tracking infrastructure to measure performance at every stage of the funnel. Each client receives a complete campaign setup covering audience targeting, creative deployment, and conversion tracking from day one.
The agency runs highly targeted campaigns serving ads exclusively to mobile crypto users, large wallet holders, and early DeFi adopters using Blockchain-Ads' on-chain targeting features. This approach ensures that client ad spend reaches qualified audiences regardless of the vertical. Whether it's a CEX acquisition campaign, a DeFi protocol user acquisition push, or a Layer 1 token holder campaign.
LeanMarketing optimises each campaign toward conversions using retargeting to re-engage users who have shown intent but not yet converted. Creative testing and precise budget management across the portfolio allow the agency to maintain an average CPA of $180 across 27 active clients. At the same time running 97 campaigns spanning multiple crypto sub-verticals.
