Fractional, With a Full-Time Attitude™

C-Suite Advisory for private companies.

Strategic finance and operational lift — a trusted right hand, without the full-time cost.

Senior financial leadership isn’t one-size-fits-all. Tideway embeds alongside CEOs to strengthen financial clarity, operational alignment, and leadership execution where the business needs it most.

Support may be delivered on a fractional or interim basis during periods of growth, transition, or complexity — but the focus remains the same: helping leadership teams move forward with confidence.

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

Why Tideway Exists

As privately owned 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 — 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 — 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.

Founder & Principal Advisor

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.

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.”

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.”

ENGAGEMENT MODELS

How Tideway shows up depends on the moment — but the objective stays the same.

We work with clients through flexible engagement models that adapt to the stage of the business, the level of complexity, and the support required at a given point in time.

We offer two flexible ways to work together, depending on your stage, priorities, and internal capacity:

  • Ongoing, part-time executive support that provides senior financial leadership with embedded execution.

    This model flexes between CFO, Chief of Staff, and strategic advisor — depending on where the business needs clarity, confidence, or traction most.

    Best for:

    • 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.

  • Short-term, full-time (or near full-time) executive leadership during periods of transition or intensity.

    Interim engagements provide immediate CFO, Chief of Staff, or hybrid leadership — while operating through Tideway’s integrated strategic advisory lens to stabilize the business and move it forward.

    Best for:

    • 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

    Where appropriate, Tideway partners with a boutique recruiting firm to support the permanent search — ensuring continuity between interim leadership and the long-term hire.

CORE SERVICES

Our services reflect where a business needs senior leadership most. Whether the priority is financial clarity, operational execution, or leadership alignment, Tideway provides embedded support designed to move the business forward — not just manage it. The specific role and engagement model are determined after Discovery, based on what the business actually needs in the moment — not a preset formula.

CFO

Financial clarity, structure, and strategic direction.

  • Financial modelling, cash oversight, and capital planning

  • Budgeting and forecasting

  • KPI development and performance reporting

  • Investor and board preparation

  • Transaction and transition support (financing, acquisitions, succession)

COS

Execution, alignment, and organizational traction.

  • Strategic planning support and alignment

  • Communication and cross-functional coordination

  • Leadership and meeting cadence design

  • Accountability and project traction

  • Operational problem solving and CEO-level execution support

Hybrid (CFO + COS)

For companies needing both strategic clarity and operational momentum.

  • CFO provides financial visibility, cash oversight, and strategic direction.

  • COS strengthens execution, communication, and organizational alignment.

  • Together, they form a complementary right-hand partnership that supports decisions, follow-through, and momentum across the business.

  • CFO work continues throughout — COS doesn’t replace it, it amplifies it.

All Tideway engagements are grounded in strategic advisory. Whether operating as CFO, Chief of Staff, or a hybrid of both, Tideway brings senior judgment, decision clarity, and strategic perspective — not just functional execution. The role may flex — CFO, Chief of Staff, or both — but the objective remains the same: better decisions, stronger execution, and durable value creation.

Your Questions, Answered

  • A: Every engagement begins with a no-pressure discovery call to understand your goals, challenges, timing, and capacity needs. If there’s alignment, we’ll follow with a proposed engagement letter outlining the recommended approach and model.

    Depending on your stage and complexity, you may need:

    • Fractional — ongoing part-time leadership for clarity, momentum, and consistency

    • Interim — higher-intensity temporary leadership to stabilize a transition or gap

    • Project-Based — defined deliverables with a clear start and end point

    • CFO + COS blended support — strategic finance + operational execution in one integrated role

    Most engagements begin with a strategy workshop or deep-dive to set direction and establish priorities.

    Our process: Discovery → Engagement Letter → Kickoff → Fractional, Interim, or Project Journey

  • A: Tideway is typically brought in when a business has outgrown its current internal capacity but isn’t ready for a full-time executive hire.

    This often shows up in a mix of strategic, operational, and financial challenges.

    Strategic & Operational Challenges

    • Founders or CEOs stretched too thin
    • Strategy not translating into execution
    • Communication or leadership gaps
    • Stalled initiatives or project gridlock
    • The need for stronger systems and structure as the business scales

    Financial Visibility & Planning

    • Limited financial oversight or unclear reporting
    • Cash flow uncertainty
    • Misaligned KPIs or unclear performance drivers
    • Finance teams that need stronger leadership or context
    • Gaps in banking, lender, or investor communication

    In these moments, Tideway steps in alongside the leadership team to bring financial clarity, operational structure, and momentum to the business.

  • A: Most companies bring Tideway in at an inflection point - when the business has grown beyond its current internal capacity but isn’t yet ready for another full-time executive hire.

    Common signals include:

    • Leadership teams spending too much time reacting instead of planning
    • Financial information not providing clear insight into business performance
    • The business has outgrown the structure around the founder, Controller, or EA
    • Strategic decisions feel riskier than they should because financial visibility is limited
    • Growth, capital discussions, or operational complexity are increasing

    At these moments, Tideway steps in alongside the leadership team to bring clarity, structure, and momentum to the next stage of the business.

  • A: We work on a fixed-fee monthly retainer or a defined project fee — no billable hours, no surprise invoices. You’ll always know exactly what you’re getting, and who you’re working with.

    Retainers create predictability, remove billing uncertainty, and allow us to show up as a true team member — invested in outcomes, not watching the clock. Engagements often begin with more in-person or intensive support to build clarity and momentum, then evolve into a steady rhythm of fractional leadership as your needs change.

    The first step is a free discovery call to scope the right fit.

  • A: Yes. Fractional and interim work give us the focus and flexibility to show up fully engaged. Many clients experience more value than full-time hires because we’re not stretched thin or distracted by internal noise.

    Support is often heavier at the beginning to build clarity and momentum. Over time, the rhythm may shift — combining ongoing touchpoints with execution behind the scenes — ensuring the right level of leadership without the full-time overhead.

  • A: Unlike traditional consultants, we don’t deliver decks and walk away. We integrate with your leadership team, bring a CPA-level financial lens, and drive initiatives with accountability. You get a trusted right hand — not a detached service provider.

  • A: Many firms provide a traditional fractional CFO focused on reporting, forecasting, and capital management. That work is important — but often not enough.

    Tideway blends CFO expertise with the execution and alignment of a COS. This dual-role model bridges finance, operations, and people — ensuring you get:

    • The numbers to make the right decisions and

    • The operational horsepower to ensure those decisions get implemented

    The result: clarity, alignment, and momentum — without the cost or commitment of a full-time executive.

  • A: Our model pairs two critical functions:

    CFO: cash flow, reporting, forecasting, long-term value creation


    COS: execution, cross-functional alignment, communication, unblocking priorities

    Together, they provide strategic clarity and the operational horsepower to ensure decisions actually get done — without full-time cost.

  • A: Not necessarily. Some companies need one or the other; others need a blended approach. During Discovery, we help you determine the right mix based on your clarity needs, operational gaps, and leadership structure. Many companies evolve into blended support once financial clarity is in place — but some need it from day one. We right-size the structure to your stage and complexity.

  • A: Tideway works collaboratively with your internal team or outsourced partners — including bookkeepers, Controllers, and other finance support.

    We don’t replace any day-to-day roles the company may require. Instead, our role sits at the operational finance and strategic oversight level while the existing team manages the day-to-day transactions, reconciliations, and filings.

  • A: We operate best when treated like part of your leadership team.
    That means full access to rhythm, data, and strategy — and the ability to drive accountability and alignment across departments.

    We are hands-on, not on the sidelines.

  • A: Over time, yes — but not by removing the owner or changing who’s accountable.

    As financial clarity improves and execution becomes more consistent, fewer decisions need to funnel through one person. Leadership ownership strengthens, priorities move forward more smoothly, and the business becomes easier to run — even while the owner remains actively involved.

    This is typically a longer-term outcome of our fractional engagement model, where continuity, context, and follow-through allow meaningful improvements to take hold without disrupting how the business operates.

  • A: Yes. When needed, we partner with a boutique recruiting firm to help you hire the right long-term finance talent — whether that’s a bookkeeper, Controller, analyst, or operational role.

    If we’re providing interim leadership, recruiting can run in parallel. We’ll help scope the role, vet candidates, and ensure a smooth handoff so the team is set up for success.

  • A: Our sweet spot is founder-led and owner-operated businesses at inflection points — rapid growth, transitions, restructuring, or strategy execution needs.

    We support companies requiring financial leadership and operational execution without committing to a full-time hire.

    We also help earlier-stage companies preparing to scale on a case-by-case basis.

  • A: Our core work is with businesses — but we also offer strategy packages for individuals starting their own consulting or fractional practice.

  • A: We work with only a small number of clients at a time — so each one receives the focus, depth, and support usually reserved for a full-time executive. We don’t take on competing clients. When we’re in your business, we’re fully in it.

  • A: At Tideway, we use AI in simple, practical, and responsible ways to support better decision-making. AI helps us speed up analysis, surface insights, and streamline parts of the finance and operations process - but it never replaces judgment, experience, or the relationship we have with clients.

    We adopt AI with care:

    • We protect sensitive client information.

    • We balance innovation with accuracy and discretion.

    • We only use AI when it genuinely strengthens outcomes.

    Our goal is to help companies understand their numbers, operate more smoothly, and make confident decisions—not to overwhelm them with tools or trends. AI is just one of the ways we bring clarity and execution support to the businesses we work with.

No Buzzword, No Taglines. Just Clarity.

No buzzwords.

No fog.

Just clarity.
