Filecoin ProPGF Batch 2 (General Track): $3.22M Allocated to Core Infrastructure and Ecosystem Builders

PLFIF is excited to announce the results of Filecoin Public Goods Funding (ProPGF) Batch 2 - General Track, with $3,220,200 allocated across 16 projects supporting critical infrastructure, developer tooling, ecosystem growth, and coordination within the Filecoin network.

Batch 2 reflects a maturing funding strategy: more selective, more capital disciplined, and strongly aligned with long-term network resilience.

🌱 About ProPGF

Protocol Labs’ Filecoin Public Goods Funding (PGF) programs support projects that strengthen the Filecoin ecosystem and broader open-source infrastructure.

Funding is distributed through:

• ProPGF - Prospective funding for forward-looking initiatives
• RetroPGF - Retroactive rewards for demonstrated impact

While RetroPGF evaluates past impact, ProPGF is designed to strategically allocate capital toward future ecosystem priorities through milestone-based funding and structured review.

ProPGF runs in recurring cycles and continues to evolve as Filecoin’s capital formation layer matures.

📊 Batch 2 at a Glance

• 102 total applications
• 53 shortlisted
• 42 advanced to final review
• 16 projects funded
• $3,220,200 allocated
• The majority of grants are structured over 6 months, with select soft commitments extending toward 12 months

This represents a 15.7% acceptance rate, reflecting the rigor of the review process and the competitive nature of the round.

🧮 Capital Discipline & Negotiation

Across the 16 selected projects:

• Total requested: $4,632,800
• Total approved: $3,220,200

Note: Batch 2 reflects a more capital-disciplined approach: of the $4.63M requested across selected proposals, $3.22M was approved. This reflects a selective funding approach - prioritizing scope clarity, milestone alignment, and long-term ecosystem impact.

The committee conducted structured negotiations across scope, milestones, and budget sizing to ensure:

• Capital efficiency
• Alignment with ecosystem priorities
• Clear accountability through milestone gating

Average grant size: $201,262 Median grant size: $129,000

This reflects a portfolio approach — balancing large, high-leverage infrastructure bets with smaller, targeted interventions.

🏗 Funding Allocation by Category

Batch 2 demonstrates a clear prioritization of core network stability and dependencies.

Capital Distribution:

• Infra & Core Dependencies: 62.4%
• Tooling & Developer Ecosystem: 16.1%
• Ecosystem Growth: 16.3%
• Coordination: 3.1%
• Integrations: 2.0%

Over 60% of capital was allocated toward core infrastructure — nodes, maintenance, retrieval systems, indexing, and protocol-level dependencies — signaling strong emphasis on network robustness.

📈 What Batch 2 Signals

Compared to earlier cycles, Batch 2 reflects:

• Stronger selectivity (16 out of 102 funded)
• Greater capital concentration into core infrastructure
• Clear negotiation discipline
• Emphasis on long-term network sustainability

This was not a broad experimentation round. It was a stability and resilience round.

📉 For Teams Not Selected

We recognize the high quality of many proposals that were not funded in this cycle.

ProPGF operates within a defined capital envelope and prioritizes strategic alignment, scope readiness, and budget feasibility.

Importantly, we are currently working on a separate grant initiative outside of ProPGF, designed to support projects that may be better suited for a different funding structure or scope.

Our team will be reaching out directly to selected applicants as this program takes shape.

We strongly encourage teams to remain engaged and apply in future cycles.

💸 What Happens Next

• Agreements and KYB completion
• Milestone tracking via Karma
• Grantee Slack onboarding
• Structured reporting and transparency

Initial disbursements begin shortly.

🔭 Looking Ahead

As Filecoin continues to mature, so too does its capital allocation strategy.

ProPGF is evolving toward:

• Greater funding transparency
• Stronger milestone accountability
• Better capital efficiency
• Alignment with long-term network KPIs

Batch 2 marks another step toward building sustainable capital infrastructure around Filecoin.

We’re excited to support this cohort and look forward to sharing more about the long-term roadmap for ProPGF in upcoming posts.
