Cofounder Split After One Side Built Everything
Early contributors to startups often find themselves in situations where their initial equity or compensation doesn't reflect their significant contributions to the company's growth and vision. This can lead to feelings of being undervalued, exploited, and a desire to leave, especially when fundraising rounds introduce new power dynamics and demands. The pain is compounded by a lack of understanding of equity structures early on.

“So here’s the picture. I started with an idea in 2023. States dating her in 2024. Until then I haven’t really worked in the idea. I started working on it since April 2025 and it started making money since July 2025. Till then she has…”
“NEVER split equally - it pretty much always leads to issues. The higher equity should be to the person that is doing more work/putting in more aka the person without which the idea dies or the other stops working on it. The final decision has to rest with one person - takes input from others but makes the final call Outsourcing isn’t bad especially if they are using the saved time to make more money to put into the business. If it’s just because they don’t want to put in the time or their hourly”
“I would never enter a business on a fifty fifty. Somebody has to make the final decision. No matter what you decide to do, put a ironclad buy sell agreement in place. I would also define roles pretty specifically in the corporate documents.Because if someone's not doing their part, it should be able to trigger repercussions. Check with the banks that you plan to use. In texas, if a partner has twenty five percent or more equity, they have to be present to sign for any financial loans or line”
“I second the value created portion, but this is hard to measure. As an engineer I will tell you the guy who can make 1 call and in 5 minutes land a $10M check is more valuable to a company than someone who builds amazing products or has amazing ideas. No matter how great a product you build, it’s pretty meaningless if no one buys it. Sales, marketing, and fund raising are more important than building the product (look at all the meh projects that have big exits) but also less visible on a spread”
“I’m looking for advice on founder equity and incentives rather than validation that one side is right. About a year ago, I started building a software product and invited a friend to join me as a co-founder very early on. We verbally agreed on a 50/50 split, but nothing was ever formalized. Over the last year, I’ve worked on the project almost full-time while building most of the product. My co-founder’s intended responsibilities were art/design and sales. He’s contributed ideas, feedback, and d”
“Hi everyone, I’m in tech and the company that had worked for many years was acquired by a PE several months ago. My share of the acquisition after tax came down to $7.6M and was deposited. So based on what I learned I’m already fatFIRED ??!! Without even thinking about it, I distributed proportionally across my stock portfolio and kept doing what I was doing until I came across this sub and start reading, the PE also put in a new contract for me and gave me some shares in the new post acquisitio”
“Your title mentions opportunity for FAANG-tied fractional CTO - a label that perceives that just someone who has worked for aligned companies are the ones more “qualified” to the position you’re looking for. I think to help better with your search, try to say i’m looking for fractional CTOs that can do x,y,z because the label of CTO or any other title is dependent/relative to the organization they’re employed.”

“Did you read the rest of my comments in this post (just curious but I feel like you're missing a lot of context) I don't care if I raise a round, it's all been bootstrapped so far and I am fine continuing to bootstrap.

“You will need to bring capital to the table to be taken seriously. There's no way I would finance this unless you also had skin in the game.”
“I’m sure you have thought this through but in my entrepreneurial journey all my challenges have been through partnerships going badly. Ultimately if you can afford it then go it alone, however if you need the equity and the partner brings significant leverage or something special then carefully consider what proportion of the business you offer up as equity. If you are taking the lion share of the risk or have more skin in the game then make sure you are majority shareholder so you can control t”
“Hello guys, I need your opinion, I’m willing to start a project, I have an investor on board and I don’t know how much equity should i give him. What ive brought to the project so far: –The original concept and product direction -Sourcing of factories and labs to produce with -Product selection \-Company name and logo/branding -I’ll be leading the project long-term, starting as commercial assistant and handling marketing What the investor will bring: -Full financing of the project costs ($30k ap”
“I don't see how it's not a lotto ticket in this situation. The company doesn't have PMF, and the founder is going to raise capital - and in this environment, at minimum OP is going to diluted by any investors that come in, and the investors will near certainly be higher on the cap table.”
“First employee, single-digit equity, same salary since before the company had traction, joined straight out of college. I do most of the engineering work. Coming up on a vesting cliff, under a year out, and trying to decide if the equity justifies staying underpaid to reach it. Traction today, after two years of basically zero revenue and a pivot, coming up on year three: six-figure pilot contracts with big-name enterprise customers, a couple hundred k a year total. The money is a rounding error”
“We literally have two companies where on makes and the other sells. Partnership is equally split in each of the companies, salaries and profits are equally split. This is how partnerships are supposed to work and there are agreements spelling out how it’s done. The other option is two companies, separately owned and operated by each one of you with some kind of minimum buy sell agreement between the companies.”
“The key sentence here is: "There is a possibility to scale in the next months". Turn that possibility into a falsifiable deadline. For example: give the company 6 more weeks, add no major features, and require one new recurring customer or one paid pilot. Also define the exact external event expected to unlock growth: a named prospect, signed proposal, partner launch or procurement decision. If the threshold is reached, continue with better evidence. If it is missed, stop or radically”
Yes it’s a limited company. All have 25% equity. 2 are CEO.
“Solid questions from handruin already. Two things I'd add that are easy to miss. First, get clear on whether the 60/40 is on gross revenue or on profit after supplies and overhead. 40% of gross shrinks fast once product, water, and power come out, so those are very different deals. Second, who owns the customer. If you build a book of repeat clients working out of their shop, do those clients come with you if the partnership ends, or do they stay with the car wash? Nail that down in writing”
“Yeah, interesting for sure. Large part of our discussion as well. Since multi-generation, what does the post-close look like? Is it weird if we all have employment agreements for a set time period then all leave? A lot to think about. Real risk in being wined and dined, but not liking how it’s run after, but it’s not our responsibility or choice at that point. Would be weird!”
“20% each, 4 year vesting with a 1 year cliff, and a well though out shareholder agreement to define roles and expectations.”
“Think in terms of the opportunity cost of capital such that if you take some chips off the table, you can invest it elsewhere for a comparatively better risk adjusted return.”
“Why are you getting more equity than others? Why are you getting so many cofounders? 500$ is too small for making equity decisions on. I would say handle it as loans to the business. Equity divide equally makes sense with a 4 year beating with first year cliff. Still seems like too many casual interest people are being named co-founders and you don't have actual co-founders. Time to make a decision. I would recommend increase the initial investment and have one or two.”
Thank you. I will look into this and make sure it’a brought yp
“Oh absolutely! Its all about how the payouts are structured. If they acquire a company and in 5 years sell it but dont hit their made up ROI number then nothing goes to C shares holders. For example they might aim at 5x-ing the company in Y-amount of time. The by that time they are only 4x the initial value which means they didnt hit their target and C share holders get shafted while the value gets split between the higher class share holders. Thats why i said that if you have reasonable power t”
“Section 1202 gain exclusion? Try to negotiate least possible earn out or contingent payment.”
“Your m&a team is the most important decision you’ll make. Due diligence is awful. Make sure to keep your numbers up during negotiations or they’ll deval you last minute and that sucks. (Sold our consulting company for max value of $27m in September last year - 3 year earn out though)”
“Get any personal assets out of the business however you deem equitable. It’s a mad scramble otherwise. Paying for them personally with a check into the company and distributing the proceeds is fine to keep your S-election.”
“Yes, or Controller. They will also help defend you in any reconciliation period post-closing”
“If anyone has a minute to give their unbiased opinion on fair equity split... please! Two people, John and Jane. Here's the situation: - John has been providing sole trader marketing services.

“It's not "whatever you can document" it's whatever you can defend. And OP says they're handling business development for a group of companies. That sounds like a high level consulting role, I would expect comp to be higher”
“From that bits of information, I am more worried about how your cofounders would be protected against you ! Vesting is the simple, fair and known process through which every could get their shares.”
“A bit about me and some regrets: 50M tech worker here. I lucked out with stock options several years ago but failed to pull the trigger, only selling a portion of the stock at the time. I missed out on a $5.5M valuation that is now worth $1.6M (learn from my mistakes, boys and girls). TBH I'm not sure why I didn't sell then, as I was mentally ready to FIRE. Instead, I chose to continue to grind it out, and now I'm seriously burning out. I'm trying to come up with a plan that I ca”
“As other have stated, add vesting (backloaded if you’re worried people will leave early) and forget about the crazy corporate structure. Your legal fees will be sky high every time you make a change otherwise. Stick to boilerplate agreements, just adjust the percentage ownership and vesting schedules”
“Yeah this is actually what I was thinking. I don’t want to give everyone equal equity upfront especially since their contributions and commitment may be different. I want to keep control of the parent company and have the first business operate under it.”
“Yeah that makes sense. I think I’m overthinking the structure too early. I should probably focus on getting the first product launched”
“Actually money isn’t the problem. It’s just that a lot of my friends want to join the business and I feel embarrassed to leave them out.”
“It’s just that a lot of my friends want to join the business and I feel embarrassed to leave them out.”
“It’s just that a lot of my friends want to join the business and I feel embarrassed to leave them out.”
“Determine the salaries appropriate to everyone based on their experience, role, and commitment. Do NOT pretend you each get an equal share; that's insane. Use that ideal salary as your guide to split equity. Cliff and vest. Never not.”
“I’ve also seen advice that recommends working under a founding agreement that structures how the equity division conversation will happen in the future, but deferring that conversation until some more concrete milestones have occurred.”
“I’m starting a consumer brand with 5 people. Initially, everyone may invest around $500 each , with more investment later as the business grows. I don’t want to give everyone 20% immediately because someone could invest $500, stop working/investing later, and still own 20%. I also plan to personally own/control the umbrella/parent company and main brand/IP . The individual businesses (e.g., Product A, Product B, etc.) would operate under this brand, and no new sub-brand/business should be launch”
“Tell them you'd love to have them as a co founder. Do a financial evaluation of the company. Lets say the company is worth 100k. Offer them 10% for 10k. They will never mention being a co founder again.”
“Learn by doing. You can hire a broker by the hour to get help through the tricky parts.”
100% thats what my partner keeps telling me! At least I have options.
“You could always sell it, or sell interest for cash. You will need capital regardless. If you sell 30% interest for cash, do make sure your new investors/partners know the industry and can bring more jobs. The solution to no cash on hand is ALWAYS SALES!”
“5 years. A LOT of my own cash, few other shareholders that im not wanting to f over and walk away from, a product that speeds up data transfers over the internet. Im not gonna link it or name it here, not the point of this post. I'm losing my mind and need some reality checks from people who've been here. Here's the pattern: We demo the product.

“Has anyone ever had success taking a minority stake as a first step in a succession plan for the owner where it ultimately leads to a full buyout? Without being too specific, this opportunity includes physical property and an operating business. I’ve been considering a minority stake (~25%) to inject fresh capital to fund an expansion plan as the current owner isn’t ready to fully exit/retire. He’s an honest guy (not just my opinion, it’s been verified, etc) and I know I could learn from him. Af”
“OP, I think people are asking the wrong questions here. Why do you need to have a conversation telling your friend she’s not the co-owner? What do you hope to achieve from that? It sounds like the co-owner issue isn’t the real problem. It’s something else. Is it that you’re feeling like your friend isn’t respecting the choices you’re making? Is it that you wish her feedback wasn’t always so critical? You need to figure out what the actual problem is and focus on solving that, because if the issu”
“I'm a founder and recently spoke with an organization that liked our startup and invited us to join their ecosystem. Instead of investing directly, they charge a relatively small "commitment fee" to become part of the network and access mentorship, introductions, and potential fundraising support. I don't have enough experience to know whether this is common or if it's generally considered a red flag. submitted by /u/lulu0925 [link] [comments]”
“posting this as a warning, because we did everything right on paper and still nearly destroyed the company. we did the co-founder agreement. we split equity properly. we defined roles. we had all the conversations the guides tell you to have, and we had them early, and we thought we were aligned. what we never talked about, because it never occurs to anyone to talk about it, is what we each thought winning looked like. he wants to build something enormous. he wants to raise, scale hard, take the”
