The first year of a startup is dominated by product, customers, and survival. Legal infrastructure tends to land somewhere near the bottom of the priority list, right behind accounting and slightly above updating the website. That ordering makes intuitive sense – legal feels abstract until it isn’t – but it’s also how founders end up paying significantly more to fix problems than it would have cost to prevent them. At Braslow Legal, the calls we receive from early-stage founders often follow a recognizable pattern: something broke, and the underlying cause traces back to a decision made in month two or three when the business was still finding its footing.
None of the mistakes below are unusual. They’re common precisely because they feel low-stakes in the moment. By the time they surface as real problems, the business is usually bigger, the relationships are more complicated, and the path to resolution is longer.
1. Operating Without a Formal Business Entity
A lot of founders start selling before they’ve formed a legal entity. The reasoning is usually that formation can wait until things take off. The problem is that operating without an LLC or corporation means operating as a sole proprietor by default, and sole proprietors have no liability shield. If the business gets sued, if a customer is injured, if a vendor dispute escalates to litigation – the founder’s personal assets are fully exposed.
Choosing the right entity structure matters beyond just the liability question. An LLC offers flexibility and pass-through taxation that works well for many small businesses, while a C-corporation is generally necessary for startups planning to raise venture capital, since investors and most equity compensation structures require it. Making the wrong choice early doesn’t always create immediate problems, but converting later involves legal and tax complexity that costs more than getting it right from the start.
Formation is also the moment to establish the governance documents that define how the business operates: the operating agreement for an LLC or the bylaws and shareholder agreement for a corporation. Skipping these creates ambiguity about decision-making authority, profit distribution, and what happens when a founder wants out. That ambiguity is manageable when everyone is aligned. When they aren’t, it’s expensive.
2. Co-Founding Without a Written Agreement
Co-founder disputes are one of the leading causes of early-stage startup failure, and the majority of them were predictable. Two people start a company with a shared vision and an implicit understanding of how things will work. The business grows, roles shift, contributions diverge, and what felt like an obvious arrangement turns out to have been interpreted differently by each person.
A founder agreement needs to address equity splits and vesting schedules, decision-making authority, what each founder is expected to contribute, and what happens if one founder leaves – voluntarily or otherwise. Vesting is particularly important and often overlooked. If a co-founder holds 40% of the company and exits after six months, and there’s no vesting schedule in place, that founder walks away with a 40% stake they did nothing to earn. The remaining founders are left building a company they don’t fully control.
A standard four-year vesting schedule with a one-year cliff – meaning no equity vests until the one-year mark, at which point 25% vests at once, with the remainder vesting monthly over the following three years – is a reasonable baseline for most early-stage companies. The specifics should reflect the actual situation, but some version of this protection should exist from day one.
3. Treating Verbal Agreements as Binding Commitments
Handshake deals and email threads are not contracts, or at best, they’re contracts that are difficult and expensive to enforce. Early-stage startups frequently rely on informal arrangements because formal agreements feel like friction – the kind of overhead that slows things down when speed matters most. What they actually do is create ambiguity that gets exploited whenever a relationship sours.
Every vendor relationship, every service arrangement, every partnership discussion that involves money, deliverables, or exclusivity should be documented in a written agreement before work begins. This is true even – especially – when the other party is a friend or a trusted contact. Friendly relationships are often the ones where the terms are most loosely defined, which makes them the most vulnerable to misunderstanding.
The agreement doesn’t need to be long. A well-drafted one-page service agreement that clearly states the scope of work, payment terms, timeline, and what happens in the event of a dispute is far more protective than a detailed email chain that both parties remember differently six months later.
4. Neglecting Intellectual Property from the Start
IP issues in early-stage companies tend to fall into two categories: not protecting the IP you own, and not confirming that you actually own what you think you do.
On the ownership side: if contractors or freelancers built any part of your product, wrote your website copy, designed your logo, or developed your software, you need written IP assignment agreements confirming that work belongs to the company. Under U.S. copyright law, a contractor owns the work they create unless there’s a written agreement transferring ownership. A founder who built their MVP with freelance developers may not own the underlying code. That’s a serious problem for any investor doing due diligence, and an even more serious problem if the developer decides to assert ownership.
On the protection side: trademarks don’t register themselves. Common law rights arise when you start using a name or mark in commerce, but those rights are geographically limited and difficult to enforce. Federal registration with the USPTO creates nationwide priority and gives you the legal tools to stop infringers. Filing early also establishes your priority date, which matters if a competitor files for a similar mark while your application is pending.
Founders also routinely overlook the IP they bring into the company from previous employment. If you developed ideas or technology while working for a prior employer, there’s a real possibility that employer has a claim on that work under an invention assignment agreement you may have signed years ago and forgotten about. Clearing that risk early is far easier than addressing it when a former employer resurfaces during a funding round.
5. Skipping Employee and Contractor Documentation
Startups hire fast, especially when they’re growing. Offer letters get skipped in favor of verbal commitments. NDAs get forgotten because the candidate seemed trustworthy. Employment agreements get pushed to “once things slow down,” which is never.
Every person who works with your company, whether as an employee or a contractor, should have signed documentation in place before they start. For employees, that means an offer letter that clearly states compensation, role, at-will employment status (in Florida), and any equity terms. It also means an invention assignment and confidentiality agreement, which ensures the company owns work product created by the employee and that proprietary information stays protected after they leave.
For contractors, the classification question matters as much as the paperwork. Misclassifying employees as independent contractors creates tax liability, wage claim exposure, and potential penalties at both the state and federal level. The working relationship – not the contract label – determines classification, so it’s worth reviewing the arrangement before assuming contractor status applies.
Getting the Foundation Right with Braslow Legal
None of these mistakes require bad intentions or carelessness. They happen because founders are moving fast, resources are tight, and legal feels like something that can wait. The pattern Braslow Legal sees most often isn’t a company that ignored these issues entirely – it’s a company that planned to get around to them and didn’t before something forced the issue.
Building the legal foundation of a startup doesn’t have to be complicated or time-consuming if it’s done proactively. The right entity structure, a solid founder agreement, documented vendor and employment relationships, and basic IP protection put a company in a significantly stronger position – for growth, for fundraising, and for the inevitable moments when a relationship doesn’t go as planned.
If your startup is in its first year and you’re not sure where the gaps are, that’s a reasonable place to start the conversation. Reach out to Braslow Legal for a consultation and get a clear-eyed assessment of what your business actually needs to protect itself as it grows.
