How Optimus Ventures Acquired 1,450 Investors and Reduced CPA by 77% with Blockchain-Ads

High-net-worth investor sign-ups and wallet connections
Optimus Ventures is a DeFi investment platform connecting high-net-worth individuals with vetted early-stage blockchain projects. The platform provides curated seed stage access, two-way vesting with smart contract protection, and an Elite Investment Club for $OPTCM token holders. It targets experienced crypto investors with meaningful capital to deploy who seek structured, lower-risk exposure to early-stage DeFi opportunities.
A note on attribution: Optimus Ventures' paid acquisition on Blockchain-Ads is managed through affiliate partners, each running independently with their own market focus and creative approach. This case study covers one such campaign and reflects what Blockchain-Ads can deliver for Optimus Ventures-aligned partners targeting high-net-worth crypto investors globally.
Optimus Ventures needed to reach high-net-worth investors who would not only sign up but connect wallets and engage with vetted DeFi projects. All of this while driving down an initial CPA of $294 to a sustainable acquisition cost for continued scale.
The campaign faced four compounding obstacles:
Standard display networks could reach crypto and finance audiences but not verified high-net-worth wallet holders with DeFi protocol history and early-stage investment behaviour. Optimus Ventures needed users already comfortable with seed stage investments and token-gated access models who would immediately understand the platform's value proposition. Interest-based platforms had no reliable signal for portfolio size or DeFi investment depth.
Blockchain-Ads gave the campaign the targeting infrastructure it needed through four capabilities:
The campaign launched globally across high-net-worth and DeFi protocol user wallet segments with display formats.
Four creative angles ran simultaneously:
CPA opened at $294, with Phase 1 delivering 20% of total campaign conversions as the campaign gathered signal across audience segments and regions. The objective was to identify which angle drove the lowest cost per sign-up among HNWI and DeFi investor segments.
Data from Phase 1 identified DeFi protocol users and high-net-worth wallet segments as the strongest converters. The vetted projects and seed stage access angles outperformed the ROI and Elite Club angles on sign-up rate among investors already evaluating early-stage DeFi opportunities. Budget shifted toward these two creatives.
Two new angles were introduced:
Testing the new angles caused CPA to rise briefly to $301 in Phase 2, which delivered 12% of total conversions. That’s because the campaign recalibrated around the strongest performing creatives and segments.
The campaign concentrated spend on the investor protection and vetted projects angles across verified HNWI and DeFi-active wallet segments globally. Retargeting layers re-engaged users who had signed up but not yet connected a wallet or engaged with a project listing. The two-way vesting creative, "2 Way Vesting: Investors Protection," drove the highest retargeting wallet connection rate among users already inside the platform. Phase 3 delivered 68% of total campaign conversions at a CPA of $68. This represents a 77% reduction from the Phase 1 opening rate and the majority of the campaign's 346 wallet connections.
