Fractional, With a Full-Time Attitude™

C-Suite Advisory for private companies.

Tideway Advisory – Fractional & Interim CFO & COS Services in Calgary and Alberta

Why Tideway Exists

As businesses grow, the challenges rarely fit neatly into a single role. Leadership teams often find themselves:

• pulled into constant firefighting
• making decisions without clear financial visibility
• struggling to balance daily operations with long-term priorities

Tideway exists for companies navigating this kind of complexity. Sometimes growth has plateaued. Sometimes capacity is stretched or leadership gaps have emerged. Other times the business is moving through transition such as a financing event, an acquisition, succession planning, or preparation for the next phase of growth.

In these moments, financial leadership on its own often isn’t enough. Good reporting doesn’t solve execution breakdowns, unclear ownership, or decision fatigue. At the same time, execution without financial clarity can create activity without direction.

That’s why Tideway was built to combine Chief Financial Officer (CFO) and Chief of Staff (COS) leadership. The CFO lens brings financial clarity, discipline, and decision support. The COS lens ensures priorities translate into action, alignment, and follow-through across the organization.

Together, this integrated approach brings clarity, leadership, and execution into one embedded partnership - helping businesses operate with consistency, resilience, and confidence. How Tideway shows up depends on the moment, but the objective is always the same: better decisions, stronger execution, and durable value creation.

How We Work

Whether we’re fractional or interim, we lead with a Full-Time Attitude™ - bringing the depth, focus, and momentum of a senior executive embedded in your business.

We help move strategy into action by combining financial clarity with hands-on execution. Our work is led by designated CPAs who have sat in the seat, led through change, and understand what it’s like to run a business where decisions are constant and capacity is stretched.

In many companies, financial insight on its own isn’t enough. Clear reporting doesn’t stop priorities from stalling, decisions from bottlenecking, or everything from coming back to the owner. At the same time, execution without financial context can create activity without direction.

We stay close to the work by supporting decisions, helping teams follow through, and reducing unnecessary pressure and reliance on any one person so progress continues even when things get busy or unpredictable.

Traditional Approach

  • Finance Only — Reporting, forecasting, cash flow

  • Advisor — Guidance from the sidelines

  • Siloed — Finance separated from operations

  • Part-Time Executive — Limited, high-level involvement

Tideway Approach

  • Finance + Operations — Decisions tied directly to execution

  • Partner — Embedded support that helps move work forward

  • Cross-Functional — Bridging finance, operations, and people

  • Integrated Support — A combined CFO + COS model

What Makes Us Different

Tideway was built for companies that need more than advice. We work as a trusted partner embedded in the business, not on the sidelines.

  • Integrated Leadership - Most advisors focus on either strategy or execution. Tideway brings both, helping you make better decisions and ensuring those decisions actually get carried through.

  • Clarity Before Growth - We focus first on stabilizing the numbers, clarifying priorities, and creating a steady operating rhythm so growth doesn’t add pressure or risk.

  • Hands-On Partnership - This isn’t advice-in-a-deck or a monthly check-in. We work alongside you and your leadership team, in the work, with your data and real constraints.

  • Flexible, When It Matters- Fractional support is our core, but we step in more deeply when situations demand it, whether that’s during transition, urgency, or periods of change.

  • A Calm, Trusted Presence - You get a steady partner who brings clarity to complexity, helps teams align, and keeps the business moving forward when things get busy or uncertain.

We don’t just advise. We drive action.

The Story Behind the Name

The name Tideway comes from the tidal channels of our founder’s island upbringing — natural pathways that guide boats through shifting waters.

It reflects how we work: with clarity, direction, and the steady hand needed to move forward . Those same principles shape how we support businesses — helping them navigate transition, growth, and complexity.

“Companies don’t just need financial reporting, they need a partner who can turn strategy into results. Tideway was built to combine the discipline of a CFO with the execution of a COS.”

Fractional CFO | Interim CFO | Calgary, Alberta

Alyssa Dewar founded Tideway Advisory to work more closely with businesses navigating growth, complexity, and critical decision points.

After years in finance and advisory roles, she saw firsthand how often companies reached moments where financial clarity, operational alignment, or leadership capacity began to strain under growth. Tideway was created to step into that gap.

Through Tideway, Alyssa works alongside CEOs as a trusted right hand - aligning finance, operations, and execution during periods of growth, transition, or capital constraint. Her work combines strategic financial leadership with practical operational support, bringing clarity to decision‑making and structure to execution.

This often includes helping leadership teams strengthen the systems, processes, and financial visibility required to support sustainable growth. And where relevant, preparing businesses for leadership transitions, succession, or the next stage of ownership. How Tideway shows up depends on the moment, the role, and the business in front of us and not a preset formula.

With experience across a diverse range of industries, Alyssa brings financial rigor, calm decision architecture, and a practical operator mindset to every engagement.

Alyssa is a Chartered Professional Accountant (CPA, CA) based in Calgary.

“Alyssa understands both the accounting realities of our business and how to step beyond them to support real-world operational decision-making requirements.

In a very short period of time, she successfully modelled complex financial information into simple, forward-looking data and tools that leadership utilizes daily to drive better decisions.

Her strategic perspective and judgement have made her a trusted advisor and a wonderful addition to our company’s culture.”

WORKING TOGETHER

If any of this sounds like your moment, let's talk.

Most introductions start with a 45-60 minute conversation. By the end you'll know whether Tideway is the right fit and if not, you'll usually leave with a clearer picture of what is.

WHAT WE DO

CFO and COS leadership - in one embedded partnership.

A trusted right hand for the CEO, working at the intersection of financial clarity and operational strategy. Most engagements begin here — and the components below explain what that looks like in practice.

HOW THE WORK MOVES

01 · Hybrid

Strategic Right Hand

THE ANCHOR OF WHAT WE DO

The combined CFO + COS model. A trusted right-hand and strategic advisor working at the CEO's side, spanning financial clarity and operational execution in one embedded partnership.

  • CFO provides financial visibility and direction

  • COS strengthens execution and communication

  • One partner across both — not two contractors

  • Engagements flex as the business grows


02 · CFO

Financial Clarity

WHERE MOST ENGAGEMENTS BEGIN

The structure every other decision rests on. Built once, maintained reliably, explained plainly.

  • Financial modelling, cash oversight, capital planning

  • Budgeting, forecasting, KPI development

  • Investor and board preparation

  • Transaction and transition support


03 · COS

Operational Alignment

WHERE CLARITY BECOMES ACTION

The connective tissue that turns financial clarity into priorities the team can act on.

  • Strategic planning support and alignment

  • Meeting cadence and accountability design

  • Cross‑functional coordination

  • Operational problem solving

WHERE TIDEWAY OFTEN GETS PULLED IN

Tideway is brought into businesses during periods where growth, complexity, or transaction activity begins to outpace the company's existing structure.

This includes:

  • Founder-led businesses preparing for investment, financing, or a future ownership transition

  • Companies navigating lender or investor pressure

  • Leadership teams experiencing operational strain as the business scales

  • Organizations preparing for acquisition, integration, or succession

  • Businesses entering a transaction process that require financial, operational, and leadership readiness - from early preparation through to close and beyond

In these moments, businesses need more than financial oversight. They need embedded leadership that connects finance, operations, and execution - and helps management teams navigate change with clarity and confidence.

Tideway works alongside M&A advisors, deal teams, and lenders - bringing the financial rigor, operational structure, and leadership capacity that transactions demand on both sides of a deal.

ENGAGEMENT MODELS

Two ways to bring Tideway in.

The work doesn't change, the shape of the engagement does. Most clients pick one and let it grow from there. Below is how we'd describe the two on a phone call, with nothing in between.

Fractional Leadership

ONGOING · PART-TIME

Best when:

  • Growing businesses seeking stability, strategic direction, and follow-through

  • CEOs who want a trusted, senior right hand not just functional support

  • Companies that need executive-level leadership without a full-time hire

This is Tideway’s core engagement model, designed to evolve as the business grows. The role adapts over time without losing continuity, context, or accountability.

Interim Leadership

SHORT-TERM · INTENSIVE

Best when:

  • Executive turnover or parental leave

  • Periods of rapid scaling, restructuring, or transition

  • Capital raises, financing preparation, or audit readiness

  • Urgent operational or leadership gaps requiring senior judgment

When applicable, Tideway partners with a boutique recruiting firm to support permanent searches. Ensuring continuity between interim leadership and long-term hires.

Not quite ready?

Not every business is ready for fractional or interim support and that's okay. If you're still figuring out what the business needs, these engagements are designed to provide senior strategic input without a long‑term commitment. They also work as on‑ramps, most clients who later move into Fractional started here.

Not sure which fits? Start with a Strategy Session. We'll know within an hour whether the right next step is a project, a longer engagement, or simply a clear answer you can run with on your own.
