How we engage

From first conversation to embedded partner. In four deliberate moves.

01 · Discover

Map what exists.

A confidential review of your books, advisors, and reporting needs. We map what exists before we touch a thing.

TYPICALLY · 1–2 WEEKS
02 · Onboard

Build the foundation.

Source systems connected, chart of accounts established, controls implemented, reporting in place. Built in our environment, validated, then deployed into yours.

TYPICALLY · 3–6 WEEKS
03 · Embed

Own the work.

Run the monthly close, maintain oversight, deliver reporting. The conversations that matter happen with the people who own the work.

ONGOING
04 · Quarterly Review

Adjust with intent.

Strategic check-in across capital, controls, and roadmap. Adjust scope, bring in senior support where appropriate, retire what's no longer needed.

Featured Product · Spero Intelligence

Spero Intelligence: The financial operating layer behind every engagement.

A purpose-built workspace for senior finance teams. Connected to the books, the bank, the cap table, and the people running the business. AI-native, audit-ready, and quietly precise.

  • Live financial visibility. Cash, runway, burn, and unit economics streamed direct from source systems.
  • Board-ready reporting. Monthly packages, KPI decks, and lender memos generated and reviewed in hours, not weeks.
  • Embedded analyst layer. AI agents that surface anomalies, draft variance commentary, and prepare your team for every conversation.

Brand Ethos

Finance, as it should be in the modern era.

01

Institutional-grade

Senior judgment, controls, and discipline, with the precision of a professional-grade services firm.

02

AI-native

Workflows, decisions, and deliverables designed from the ground up around real-time intelligence. Not bolted onto legacy spreadsheets.

03

White-glove

A senior finance team that knows your business intimately. No tickets, no handoffs, no roster of names you'll never meet.

Spero exists to redefine what modern financial leadership looks like. We deliver institutional-grade finance with the care, discretion, and accountability of a true white-glove partner. Embedding ourselves alongside founders and executive teams as trusted stewards of capital, strategy, and scale.

By combining human judgment with AI-driven analysis, we move faster, see deeper, and surface clarity where traditional finance teams rely on lagging indicators and manual effort. Clients experience the confidence of a senior finance team that knows their business intimately, while benefiting from systems that continuously learn, adapt, and scale.

Leadership

A team that owns the work. Accountability built in.
