One operator. Full vertical range. A platform instead of a bench.
Thriai exists because the fractional CFO market has a structural problem: the senior person who wins the engagement hands the work to someone junior. We solved it by replacing the junior bench with a governed data platform and AI agents, and keeping the senior person on the account.
Eric Anderson
Founder and principal. Eric has run finance at every altitude a growing company needs: full accounting and HR operations as a controller, FP&A management at a SaaS identity company with enterprise customers, board packs, compensation design, pricing analysis, and diligence on two exits and an equity raise.
He also builds. In production, not in slides: an in-house planning and reporting stack on DuckDB and dbt with penny tie-outs, an OAuth-secured semantic layer that a CFO queries through AI every week, a cloud BI platform, CPQ and CRM administration, and AI cost governance across multi-agent delivery with QA gates.
That combination is the firm. Most fractional CFOs cannot build the platform. Most AI consultancies have never closed a month. Thriai is the overlap.
Depth, specifically
- ARR rollforward, NRR and GRR methodology, churn and cash forecasting for SaaS
- Compliance-driven expansion motions in enterprise identity software
- Salesforce and CPQ architecture, quote-to-cash audits with findings in dollars
- Governed finance data: dbt, DuckDB, semantic layers, MCP-based AI access
- M&A diligence data rooms, board and investor reporting
Thriai does not perform audits, reviews, or tax return preparation. Those go to partner CPA firms we coordinate with.
Thriai, pronounced thry-A-I.
In Greek myth the Thriai were three sisters on Mount Parnassus, near Delphi, who taught Apollo to divine the future by casting pebbles. Their name comes from the verb for it. Counting pebbles is also the root of the word calculus. A firm that forecasts by counting things carefully, with a little intelligence built into the name, seemed about right.
How we work
Senior only
The person you meet on the first call is the person who owns your close, your forecast, and your board package. Transaction processing runs through vetted partners inside our quality gates, never through an unsupervised junior.
Evidence, not trust
Every number that reaches you has passed automated tie-outs against source systems. When something is off, the pipeline says so before you do.
Yours to keep
The platform is built in your repo, in your cloud, in open tooling. If we ever part ways, you keep a working finance stack rather than a partner's spreadsheet.
