Accelerate Ecosystem Growth
Ecosystem growth means attracting builders — and keeping them after the incentives stop. In competitive fields like AI or crypto, you can't wait months to know what worked. OSO shows where new builders enter, how they move, and when they fall off. Instead of anecdotes or vanity metrics, you get retention curves and early indicators of durable growth.
Get StartedHow It Works
OSO tracks cohorts of users, developers, and applications across your ecosystem and peer ecosystems. We connect their activity to specific programs and investments, so you can see what drives real growth.
Monitor Entire Ecosystems
OSO measures every aspect of your ecosystem, from funding to developers to dependencies to user activity. Understand impact your way with multi-dimensional metric models.
Speed Up Time-To-Insight
With hundreds of built-in data models, quickly see how your strategies are working. Create new models and analysis with ease with OSO AI Agent.
Understand The ROI of Your Efforts
Speed up your experimentation feedback loop by understanding the impact of your growth strategies. See how your performance stacks up against the competition. Take advantage of built-in causal inference techniques.
Integrate With Ease
Connect our datasets to your internal CRM and databases with secure privacy controls. With dozens of data integrations, we make it easy to enrich your proprietary datasets.

Ethereum
Mapping the world's largest smart contract developer ecosystem
Ethereum leads all blockchain ecosystems in developer activity, yet OSO's longitudinal analysis across 11 years of GitHub data reveals a strategic paradox: the experienced professional core is growing steadily while the newcomer pipeline has collapsed nearly 70% from its 2021 peak. Understanding which signal is the real story — and what to do about it — is where data-driven ecosystem management begins.

The experienced core is healthy — but the pipeline is depleted
Developers with 1+ year of tenure show cycle-independent growth, confirming Ethereum's professional base is structurally sound. However, newcomer inflows peaked in the 2021 bull market and have since fallen ~70%, reaching roughly 40–60 new qualified builders per year across the top 40 DeFi protocols by 2024. Long-term ecosystem health depends on replenishing this pipeline before the attrition math turns negative.
Solana is not poaching Ethereum talent
Net cross-ecosystem migration between Ethereum and Solana over five years amounts to just 10–30 developers — effectively zero. When builders leave Ethereum DeFi, they overwhelmingly go inactive, not to a rival chain. The competitive threat from Solana is in newcomer acquisition (both ecosystems compete for the same shrinking entry-level pool), not in experienced developer defection.
Developer tooling is the highest-ROI talent pipeline
Over 65% of qualified DeFi builders had prior open-source experience before joining their home protocol, and tools like Foundry, Hardhat, and Truffle are the leading on-ramps. Investing in developer tooling quality functions as recruiting infrastructure — it attracts the most retainable segment of future builders before they've chosen an ecosystem.
The 3-month threshold predicts long-term retention
Analysis of the Speedrun Ethereum onboarding program (17,000+ participants) shows that sustained engagement past the 3-month mark is the strongest predictor of long-term ecosystem contribution. Experienced recruits (12+ months of prior coding history) show 50%+ long-term retention; newcomer-focused programs with high early churn produce negligible lasting impact. The implication: program design should optimize for depth of engagement, not breadth of enrollment.
