About AdAstra

Built to handle
what most firms
can't.

AdAstra is a practice anchored in financial operations leadership, with a trusted network of specialists across legal, accounting, ERP, and fundraising that can be brought to bear on a client situation when the work requires it.

The result is an advisory practice that can walk into genuinely complex situations — cross-border transactions, mid-implementation ERP rescues, imminent fundraises, covenant compliance — and handle them without sending you elsewhere for half the answer.

The AdAstra network

The right specialist
for every situation.
In the room when needed.

Every engagement is led by AdAstra's financial operations practice. But the situations our clients face rarely stay neatly inside one discipline. A fundraise needs clean financials and a clean cap table — which means legal review. An ERP implementation touching international operations needs a compliance lens. A PE process needs quality of earnings support alongside the financial clean-up. AdAstra brings the right people to the table, drawn from a trusted network built over 17 years of working relationships.

Legal

Corporate & commercial counsel

Contract review, commercial law, and corporate structure advisory. When a client situation requires legal eyes on a vendor agreement, a fundraising instrument, a new entity structure, or a covenant — we have a trusted commercial attorney who can engage directly with the client's counsel or take the lead.

Accounting & Tax

CPA — audit, tax, and technical accounting

When an engagement requires formal audit preparation, technical accounting opinions, tax structuring, or a second set of eyes on a revenue recognition policy — we have a CPA partner who has worked alongside AdAstra in complex engagements and understands how the practice operates.

ERP Implementation

SAP implementation specialist

For clients operating in or migrating to SAP environments — one of the most complex ERP ecosystems in enterprise software — we have a dedicated SAP implementation partner with hands-on project delivery experience. This is not a referral. It is a working relationship built on prior engagements.

Fundraising & Capital

Fundraising strategy & investor relations

AdAstra handles the financial infrastructure side of a raise — clean books, defensible revenue recognition, board-ready reporting. Our fundraising partner handles the capital markets side: pitch strategy, investor targeting, and the narrative that sits on top of the numbers we build.

Product

Product strategy & operations

For clients where the financial model is inseparable from the product architecture — SaaS pricing changes, marketplace unit economics, product-led growth transitions — we have a product expert who bridges the gap between what finance needs to model and what product is actually building.

Financial Operations

AdAstra — the practice anchor

Every engagement is led and owned by AdAstra's financial operations practice. The network specialists are brought in when the work requires it — not by default, not to inflate scope, and not without the client's awareness. The engagement lead stays constant throughout.

How the model works

One engagement lead.
The right team
behind it.

AdAstra engagements are not staffed like a consulting firm — layers of associates managed by a partner who shows up for the kickoff and the final presentation. Every engagement has a single lead who owns the work, understands the client's situation, and is accountable for the outcome.

Network specialists are brought in selectively — when a specific situation requires their expertise, when the client's existing counsel or accountants need a counterpart, or when a parallel workstream requires dedicated resource. The client always knows who is involved and why.

This model is how a small practice handles genuinely complex situations. Not by pretending every problem fits one toolkit, but by knowing exactly which specialists to call and having the relationships to make that call work on a real timeline.

Single engagement lead throughout

One person owns the relationship, the scope, and the outcome. No handoffs to junior staff. No account manager sitting between you and the person doing the work.

Specialists engaged by situation, not by default

Network partners are brought in when the work genuinely requires them — not to inflate scope or justify fees. Most engagements stay within the core financial operations practice.

Working relationships, not referrals

Every specialist in the AdAstra network is someone we have worked with directly in prior engagements. We know how they operate, what they're good at, and when not to call them.

Defined scope, transparent pricing

Engagements are time-bound with clear deliverables and transparent pricing. When a specialist is brought in, the scope and cost are defined upfront — not discovered later.

Founding background

Phillip Coomes, MBA

Founder & Managing Partner

AdAstra was built from 17+ years of finance and accounting leadership across climate technology, Fortune 500 logistics, international government infrastructure, and SaaS — the kind of breadth that comes from actually doing the work in genuinely different environments, not advising on it from the outside.

The founding insight was simple: growth-stage companies consistently face the same financial infrastructure problems — broken ERPs, unready financials, cross-border compliance gaps — and consistently lack access to the kind of senior, operational expertise that can actually fix them. AdAstra was built to close that gap.
