The financial operations function in most social justice organizations is under-resourced, under-tooled, and underestimated. It is also where the organization's full story lives — every grant lifecycle, every budget decision, every staff allocation, every payment received and spent. One pattern runs through all of it: accounting and development have to move in lockstep, or the story the organization tells its funders, its community, and its own leadership comes out fragmented. Slingshot is built on that pattern, from inside the seat where the fragmentation hurts.
Most movement organizations run their financial operations on tools designed for conventional nonprofit accounting — or adapted from corporate platforms — neither built for the specific complexity of fiscally sponsored movement organizations with dual-entity structures. The result is workflows that bend around platform limitations rather than platforms that serve the work.
Add the complexity of fiscal sponsorship, C3/C4 dual-entity structures, multi-year grant tracking, and the cash vs. accrual gap that most staff never get clear guidance on, and the finance function becomes a bottleneck rather than an intelligence hub.
I have run these systems from inside. The finance seat sees what leadership typically does not: grant lifecycle patterns that telegraph which funders will renew and which will quietly disappear, budget variance as an early organizational signal, compliance records as a core layer of institutional memory around financial and regulatory risk. That is direct experience, not sector analysis. The tools most organizations depend on were not built to surface any of it, and the platforms they run on quietly capture organizational knowledge for corporate models instead of returning it to the mission. Data sovereignty is the architectural response to that capture.
Slingshot is the stack. The Slingshot Duo — MIAgent Solar and MIAgent Lunar — is its anchor: a working prototype built around how a movement organization actually operates. Lunar holds the accounting side: program budgets, monthly actuals, GL (general ledger) structure, fiscal sponsor reconciliation. Solar holds the development side: grant lifecycle, payment timing, compliance posture, funder reporting. They share one data layer and they share intelligence. Lunar sees Solar's upcoming deadlines. Solar sees Lunar's spending patterns.
Each agent surfaces risks, models scenarios, and drafts output tailored to whoever is asking. Together they surface the intelligence that used to require constant coordination between finance and development staff — coordination most organizations never had the capacity for. Added team members extend the duo with new core skills on top of the shared data layer; standalone agents run on their own ground — see the full MIAgent Catalog on the Tools page for the roster around them. I built Slingshot while running these financial operations, not by studying them from outside. The argument behind these tools is written out in full.
Movement organizations were being forced into accounting software designed for enterprises, while accounting and development sat in separate systems that did not speak to each other. The result: two functions that should have been in lockstep telling one story were instead reconciling spreadsheets and missing the larger picture entirely.
Build two MIAgents that share one data layer. Your MIAgent Lunar covers the accounting reality: C3/C4 splits, fiscal sponsor reconciliation, GL structure, monthly actuals. Your MIAgent Solar covers the development reality: grant lifecycle, payment schedules, funder-specific compliance, funder reporting. Same organization, same numbers, two lenses that finally agree.
When the accounting and development functions are wired together and made legible to organizational leaders, the organization unlocks its own voice. Resource stewardship, impact tracking, and funder reporting stop being three different conversations. MIAgent Lunar and MIAgent Solar are the proof that purpose-built tools shaped around how the org actually operates are tractable and ownable today.
Three commitments shaped every decision in Slingshot. None of them are features — features get added and removed. These are constraints that could not be traded away without the tool becoming something else. Each one answers a question the sector has been avoiding.
Slingshot is shaped around three audiences inside the organization.
The demos use a fictional organization. The problems they address are real. If your organization is navigating fiscal sponsorship, dual-entity compliance, or multi-year grant complexity — let's talk about what adaptive infrastructure could look like for you.
