What Is Mosaic?
Mosaic is a Strategic Finance Platform — a category it largely helped define — designed for growth-stage companies that have outgrown spreadsheet-based financial planning but are not yet ready for enterprise-grade ERP systems. Founded in 2019 by Bijan Moallemi, Brian Campbell, and Joe Garafalo (former finance professionals from Palantir), Mosaic was built by practitioners who understood the pain of managing financial operations in scaling companies with inadequate tooling.
The core problem Mosaic addresses: at the Series B and beyond stage, finance teams spend the majority of their time assembling data from disconnected systems — pulling from QuickBooks, Salesforce, Gusto, Stripe, and Snowflake into Excel models — rather than analyzing and advising the business. The assembly work is time-consuming, error-prone, and creates models that are stale within days of completion.
Mosaic's solution is a financial planning and analysis platform that maintains live connections to all the systems a finance team relies on, refreshes data automatically, and provides modeling, forecasting, and reporting capabilities on top of always-current data.
By 2026, Mosaic has expanded significantly from its financial modeling origins into a comprehensive Strategic Finance Platform covering headcount planning, revenue forecasting, AI-powered variance analysis, and self-service departmental reporting — with artificial intelligence features that reduce the manual interpretation burden that previously occupied senior finance team time.
Financial Data Integration
Data integration is the foundation of Mosaic's value proposition. The platform maintains live connections to:
Accounting systems: QuickBooks Online, Xero, NetSuite, Sage Intacct. Actuals sync daily (or more frequently for supported integrations), ensuring the financial model is always grounded in current GAAP data.
CRM: Salesforce, HubSpot. Pipeline data flows into revenue forecasting models, linking the commercial team's deal projections to the finance team's revenue forecast.
Payroll and HR: Gusto, Rippling, ADP, BambooHR, Workday. Headcount data, compensation, and benefits costs sync automatically, keeping the headcount model current without manual updates.
Revenue and billing: Stripe, Recurly, Zuora. Subscription metrics — ARR, MRR, churn, new bookings, expansion — calculate automatically from billing system data rather than requiring manual metric compilation.
Data warehouse: Snowflake, BigQuery, Redshift. For companies with more sophisticated data infrastructure, Mosaic connects directly to the data warehouse, enabling metric definitions that span multiple source systems.
The practical impact of this integration depth: when a sales rep closes a deal in Salesforce, it appears in the Mosaic revenue model the same day. When payroll runs in Gusto, compensation actuals update in Mosaic automatically. Finance teams report spending 60-70% less time on data assembly after implementing Mosaic.
Financial Modeling and Planning
Three-Statement Model
Mosaic's three-statement model maintains a live connection between your income statement, balance sheet, and cash flow statement — all grounded in actual data from your accounting system.
The model structure separates actuals (locked historical data from your accounting platform) from forecast (driver-based assumptions that project forward). When actual results come in, they replace the forecast automatically, and variance analysis is calculated without any manual intervention.
Forecast assumptions in Mosaic are driver-based rather than line-item estimates. Instead of forecasting revenue as a static number, you define it as a function of drivers: new ARR from sales team, expansion rate from existing customers, churn rate by cohort. When these drivers change, the entire model updates in real time. This makes scenario analysis fast — changing the hiring plan automatically updates the salary expense, employer taxes, and cash runway projection simultaneously.
Headcount Planning
Headcount planning in Mosaic is one of its most well-regarded features. The headcount module maintains a department-by-department view of current employees, open roles, planned hires, and backfill needs — all with compensation band assumptions that flow into the financial model.
Department managers can access their own headcount dashboards, request new roles through the platform, and see the projected cost impact of their hiring plans. Finance reviews requests against budget and adjusts the hiring plan in a collaborative workflow rather than through email back-and-forth.
The HRIS sync means actual hires and departures flow into the headcount model automatically — the plan-versus-actual comparison for headcount is always current.
Revenue Forecasting
For SaaS companies, Mosaic's revenue forecasting module builds a cohort-based ARR model directly from billing system data:
- New ARR: Projected from the CRM pipeline with close rate assumptions by deal stage
- Expansion ARR: Modeled from historical net revenue retention by customer cohort
- Churned ARR: Modeled from historical churn rates with adjustments for contract renewal timing
- MRR/ARR waterfall: Automated calculation of the standard SaaS waterfall — beginning ARR plus new plus expansion minus churn equals ending ARR
This model updates automatically as Salesforce opportunities progress, as Stripe invoices confirm or flag churn, and as monthly billing cycles close. Finance teams no longer need to manually reconcile CRM pipeline data with billing actuals to produce an ARR forecast.
Scenario Analysis
Mosaic's scenario analysis allows the creation of named scenarios — Base, Upside, Downside, Conservative Hiring — each with different driver assumptions. Scenarios can be compared side-by-side in a single view, and can be shared with board members who receive read-only access to the scenario deck.
The board-shareable scenario feature is particularly valuable in the capital efficiency environment of 2024-2026, where boards frequently request sensitivity analysis on hiring plans, ARR growth assumptions, and cash runway under different market conditions.
AI-Powered Features in 2026
Mosaic's 2025-2026 AI roadmap has delivered several features that meaningfully reduce the manual interpretation work of finance teams:
AI Variance Explanations: When monthly actuals are loaded, Mosaic's AI analyzes significant budget-versus-actual variances and generates natural language explanations. Instead of a finance analyst spending two hours digging through expense reports to understand why marketing spent 30% over budget, the AI identifies the contributing transactions, quantifies each driver, and drafts the variance explanation. Finance reviews and edits rather than starting from scratch.
Natural Language Querying: Finance teams and department heads can ask questions in plain English — "What was our fully-loaded headcount cost in Q1?" or "Show me ARR growth by channel for the last 6 months" — and Mosaic's AI generates the corresponding view. This reduces the reporting request backlog that commonly overwhelms small finance teams in growth-stage companies.
Anomaly Detection: Mosaic continuously monitors financial data for anomalies — unexpected spikes in a cost category, revenue recognition patterns inconsistent with historical norms, payroll amounts that deviate from expected ranges. Detected anomalies are surfaced as alerts before the monthly close, allowing corrections before financial statements are finalized.
Dashboards and KPI Tracking
Mosaic provides a library of pre-built dashboard templates for common growth-stage metrics:
- SaaS metrics dashboard: ARR, MRR, net revenue retention, CAC, LTV, magic number, burn multiple
- Cash dashboard: Runway, burn rate trend, cash flow from operations
- Headcount dashboard: Department headcount, fully-loaded cost, hiring plan progress
- Department operating dashboards: Customizable views for marketing, sales, engineering, G&A with their relevant KPIs
Dashboards can be configured to deliver automated reports on a weekly or monthly schedule to department heads, eliminating the manual distribution burden while keeping business leaders informed without requiring them to log into Mosaic directly.
Board and Management Reporting
Board reporting is one of Mosaic's highest-value use cases. The platform generates board package components — financial summaries, KPI updates, scenario analysis — in a format designed for board consumption, pulling live data from the integrated systems.
The traditional board reporting process at growth-stage companies involves a finance analyst spending 2-3 days before each board meeting assembling data from multiple systems into a PowerPoint presentation. Mosaic compresses this to a review-and-publish workflow: the board package is generated automatically from live data, the finance team reviews and annotates, and the package is published directly from Mosaic rather than requiring a separate presentation tool.
Headcount Planning Deep-Dive
The headcount planning module deserves specific attention because it addresses one of the most labor-intensive finance workflows in scaling companies.
Department-level collaboration: Department managers submit headcount requests through Mosaic with their justification, target hire date, compensation expectation, and business impact rationale. Finance reviews all requests in a unified queue, models the cost impact against available budget, and approves or modifies hiring timelines.
Compensation modeling: Each planned role carries compensation band assumptions (pulled from market data or company-specific bands) including salary, equity grant value, benefits cost, and payroll taxes. The fully-loaded cost of each hire is visible in the model from the moment the request is submitted.
Scenario comparison: Compare the financial impact of a conservative hiring plan versus an aggressive one, with the cash runway and operating leverage implications visible side-by-side. This data-driven framing transforms headcount debates from advocacy exercises into financial tradeoff analyses.
Finance Team Collaboration
Mosaic includes collaboration features designed for the cross-functional nature of financial planning:
- Departmental dashboards: Custom views for each department showing relevant budget versus actual data, without exposing full company financials
- Comment threads: Annotate specific cells or metrics with questions and explanations, creating an audit trail of budget decisions
- Approval workflows: Headcount requests, budget amendments, and forecast changes route through configurable approval chains
- Version history: Every model change is tracked with author and timestamp, enabling rollback and audit capability
Pricing
Mosaic does not publish standard list pricing. Based on market information and user reports:
Implementation services are typically included in the first-year contract. Annual price increases are common as usage expands. Budgeting $20,000-$30,000 for the first year is a reasonable planning assumption for most Series B companies evaluating Mosaic.
Pros and Cons
Pros:
- Live data integrations eliminate the data assembly work that consumes finance team time
- Three-statement model grounded in actuals enables real-time variance analysis
- Headcount planning module streamlines the most labor-intensive finance workflow
- 2026 AI features (variance explanations, NL querying) meaningfully reduce analytical burden
- Board reporting delivered directly from the platform reduces preparation time significantly
- Pre-built SaaS metric frameworks reduce implementation time for software businesses
- Scenario analysis on live data enables rapid response to changing business conditions
Cons:
- Significant investment — $15,000-$80,000+ annually is prohibitive for pre-Series A companies
- Implementation requires 4-8 weeks and a dedicated finance team member to configure correctly
- Platform complexity can be overwhelming for small finance teams or part-time CFOs
- Non-SaaS business models require more custom configuration to fit the platform assumptions
- AI features are useful but still require finance team review to catch errors
- Some accounting system integrations have data refresh delays that affect real-time accuracy
Mosaic vs Competitors
Mosaic vs Pigment: Pigment is a newer, Europe-headquartered FP&A platform gaining traction for complex enterprise planning needs. Pigment's modeling engine is more flexible for intricate custom models; Mosaic's data integrations and SaaS-specific templates are more turnkey for US growth-stage companies.
Mosaic vs Planful: Planful targets the larger enterprise market with a broader feature set including consolidation and statutory reporting. For companies between Series B and pre-IPO, Planful is often over-engineered and over-priced; Mosaic's focus on the growth stage makes it a better fit.
Mosaic vs Jirav: Jirav is a direct Mosaic competitor with similar positioning and pricing. Jirav's strength is its CPA and accounting-firm distribution network, making it more commonly recommended by fractional CFOs and advisory firms. The products are comparable; the decision often comes down to the implementation partner's preference.
Mosaic vs Spreadsheets: For Series B+ companies, spreadsheets are not genuinely competitive — the data assembly burden, version control problems, and lack of real-time actuals create too much operational risk. For Series A companies, the comparison is more nuanced: a highly disciplined spreadsheet model with manual monthly updates is viable but creates systemic limitations that become acute as reporting requirements grow.
Who Should Use Mosaic?
- Series B through pre-IPO companies with a dedicated finance team of two or more
- SaaS businesses that want automated ARR and subscription metric modeling
- Companies with headcount planning complexity across multiple departments
- Finance teams spending more than 40% of their time on data assembly rather than analysis
- Businesses with monthly board meetings that require current financial packages
Final Verdict
Mosaic is the strongest FP&A platform for growth-stage companies in 2026. Its combination of deep data integrations, SaaS-optimized financial models, AI-assisted variance analysis, and collaborative headcount planning addresses the core pain points of scaling finance teams precisely. The investment is substantial but generates clear ROI for companies at the right stage.
