Fast-paced and well-coordinated. They used a clear milestone-based structure and kept scope tight, which was critical for our 5-week timeline.

What did you find most impressive or unique about this company?

Their product rethink of our oracle and dispute setup prevented what would have been a serious post-launch incident. They think beyond the code.

Are there any areas for improvement or something Cowchain could have done differently?

A more detailed liquidity simulation tool during scoping would help founders better estimate bootstrapping needs before launch.

What did you find most impressive or unique about this company?

The referral-loop tied to NFT progression was their idea, not ours - and it became the single most effective growth mechanism we have.

Would be valuable to have a built-in post-launch analytics dashboard to track in-game economy health in real time.

Describe the scope of work in detail. Please include a summary of key deliverables.

Cowchain built our full AI-powered DeFi portfolio management infrastructure. Key deliverables: - AI agent engine for autonomous position management across DeFi protocols - Protocol integration layer connecting lending, LP, and yield-farming platforms - Automated rebalancing logic triggered by market conditions and target allocations - Auto-compounding module for yield optimization across active positions - Risk management guardrails with configurable exposure and spending limits - Real-time portfolio monitoring dashboard with position-level breakdown - Smart contracts for agent-authorized on-chain actions - REST API and SDK for external integrations

What were the measurable outcomes from the project that demonstrate progress or success?

Product reached $2.3M in assets under management within the first quarter. Average portfolio yield improved by 27% after auto-compounding logic went live. Onboarded 1,400+ users in the first month after launch.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Very structured process - weekly demos, meets, async Loom updates for technical decisions, and fast response times. Never missed a milestone.

What did you find most impressive or unique about this company?

Their understanding of protocol-level risk and optimization strategies in the AI agent's decision logic was rare - most Web3 dev shops don't think that deep about DeFi mechanics.

Are there any areas for improvement or something Cowchain could have done differently?

Would love broader multi-chain protocol coverage out of the box to reduce integration time for future protocol additions.

Describe the scope of work in detail. Please include a summary of key deliverables.

Cowchain handled the end-to-end product build for our client's Banking Card.

What were the measurable outcomes from the project that demonstrate progress or success?

Launched Telegram Mini App that drove $35M in transaction volume within the first 10 weeks post-launch. Onboarded 12,000+ card users in the first two months. Zero compliance incidents - all KYC/AML flows passed regulator review on first submission.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

They were extremely well-organized. Daily standups, clear sprint milestones, and proactive communication when blockers arose. Delivered in 6 weeks as promised.

What did you find most impressive or unique about this company?

They surfaced compliance problems we hadn't scoped - BIN rules, spending limits per region, KYC tiers - and solved them before they became blockers.

Are there any areas for improvement or something Cowchain could have done differently?

More pre-built compliance templates for different jurisdictions would speed up future projects even further.
