Fundraising readiness, built before the raise opens.
Northline helps VC-backed startups walk into their next raise with models that hold, assumptions that have been pressure-tested, and the clarity to defend every number in the room.
The Outside View
The hardest thing to maintain when building toward a raise is an outside view. The people closest to the plan are the least equipped to challenge it, and proximity makes certain questions structurally hard to see. Most finance support at this stage does not solve this: a part-time CFO is managing operations, an advisor with equity has a stake in the outcome.
Northline brings the outside perspective as a structural feature of the engagement, with no prior investment in the existing model and no operational role pulling focus, so what is difficult to see from inside the business gets found before an investor looks.
Services
Northline works with founders wherever they are in the process, from a focused review of the existing model to a full partnership across the raise.
Financial models grow as businesses do. Sections get added, drivers evolve, and risk accumulates quietly over time. Technical errors are only part of the problem. A model can be structurally clean and still built on assumptions that have never been tested. A small shift in one key driver can change the entire output.
Northline reviews the financial model with no prior investment in the existing numbers, delivering written feedback with concrete improvement points, priorities, and a structural assessment. That includes a sensitivity analysis on the key drivers to show where the model is most exposed. The result: the founder knows exactly where the model falls short, where the assumptions carry the most risk, and what needs to change before an investor finds it first.
As a startup evolves, its growth drivers change with it. A model built for an earlier version of the business quickly becomes misaligned with how the company actually runs. The result is a model founders work around rather than with. In a fundraising context, that misalignment is immediately visible to an investor.
Northline restructures the financial model around the drivers the company is actually steered on. The result is a model that works as a management tool: one that reflects how the business runs, supports decision making, and holds up in investor conversations.
Startups are rarely short of opportunities. What is harder to come by is the financial clarity to evaluate them: what a specific hire, market entry, or product launch actually costs, what it could return, and what it would take to work. In a fundraising context, that gap becomes visible fast. Investors often expect founders to have modelled the decisions that shaped the business.
Northline builds business cases around the decisions that matter, grounded in how the business actually operates rather than broad assumptions. The result is financial clarity on a specific opportunity: what it costs, what it could return, and what it would take for it to work, so the decision gets made on insight rather than instinct.
Founders have a clear picture of where the company is going and what it will take to get there. That clarity is present in the financial model: a growth plan, a hiring plan, a revenue trajectory. What becomes uncertain is the moment an investor asks what happens if the plan does not fully work. What happens to burn under slower growth? To runway under delayed conversion? Scenario thinking can look like pessimism from the outside, when it actually demonstrates that the founder understands the mechanics of their own business: what is sensitive, where the model holds, and what the company does when reality diverges from the plan.
Northline builds scenario capabilities directly into the financial model, structured around the drivers that matter most to the business. The result is a set of scenarios built around the specific risks and sensitivities of the business and the raise. Together they show an investor that the founder has thought beyond the base case, which is one of the clearest signals of financial maturity a founder can give in a funding round.
In the early stages, data often lives across multiple spreadsheets filled by multiple people. That works when decisions move fast. It stops working the moment you are across the table from an investor. Is there a single source of truth? Are we comparing apples to apples? Is this conversion rate really what this sheet says it is? When those questions do not have clear answers, an investor stops trusting the plan and starts questioning everything built on top of it.
Northline maps the unit economics of the business by combining the data that exists, aligning definitions, and building a single source of truth the company can stand behind. The result is clarity on the state of the unit economics: numbers that hold up, assumptions with a clear basis, and a picture an investor can scrutinise.
Raising new funds takes significant effort, and it happens while the business still needs to be run. A founder needs to prepare the financial story, stress-test the model, work through the scenarios, and be ready to defend every assumption under investor scrutiny. Each of those things can be addressed separately. What is harder to maintain is that they add up to a coherent whole: whether the model reflects the right drivers, whether the scenarios are built on assumptions that hold, whether the unit economics support the story being told.
The strategic partnership is the full engagement. Northline works alongside the founder from the first assessment of the model through to the close, including during the raise itself when investor questions arrive that require an immediate, grounded answer. A sustained outside perspective across the entire process, one that gets sharper as the business becomes more familiar. Working directly with the founder, without layers or handoff, for as long as the raise requires, so the founder can run the business and the raise at the same time, without either one suffering for it.
Why Now
The preparation a raise requires is almost always underestimated. Running a business leaves little room to step back and pressure-test the model and the assumptions behind it. By the time the raise opens, the preparation window has already closed.
The work that determines how a raise goes happens before it starts: whether the model reflects how the business actually runs, whether the assumptions in it have been tested, and whether the scenarios have been built. By the time the first investor meeting is scheduled, those things are either in place or they are not. There is no time to fix them in the room.
The raise does not create the pressure. It reveals how prepared the foundation was before it opened.
About
I'm Dean van der Zwet, the founder of Northline.
Northline is a young practice. The experience that exists is specific, and it maps directly to the work I do.
I worked at Insify, a Dutch insurtech startup, through their Series B process. The financial model no longer reflected the business as it stood: built around earlier products, rigid in structure, and not usable for the raise ahead. I rebuilt it, adding the driver logic and calibrating it for a Series B without overcomplicating the structure. I also worked on the unit economics, pulling together data from across the business into numbers management could stand behind and investors could scrutinise. Alongside that, I built a business case for a decision the company was weighing: whether to bring a service in-house. That meant modelling the decision itself, mapping what it would cost, what it could save, and when it would pay off. The company used it to make the call on solid ground rather than instinct.
I am currently working with a seed-stage startup preparing for their next round. The engagement has covered a full model rebuild structured around the company's actual drivers, unit economics work, and sustained focus on assumption quality: making sure every key assumption has a documented basis and a defensible answer behind it. The client noted that the rebuilt model was now properly fitted to how the business is actually steered, and that having stress-tested the assumptions, they felt genuinely confident going into investor conversations.
Much of my working life has been inside startups and early-stage companies, including ventures I started myself. The context this work requires comes from direct experience: the pressure of a raise, the pace of the environment, and what it actually takes to prepare for one while still running a business.
What it means for a founder working with me is direct access to the person doing the actual work: someone who has been inside startups and understands what a raise actually demands.
Let's talk
If any of this sounds like where you are right now, the best next step is a conversation. No agenda, just a straightforward talk about the model and the raise.
