If one owns 75% of company shares, does that mean that he would have to take upon himself 75% of the company's expenses?
Another way to decide would be to do a fair valuation of the company agreeable to both the partners. Lets assume when you started the company it was worth $10,000 and to acquire 75%, you must have put $7,500 worth of money and effort. Similarly, the other partner must have put $2,500 worth of time and money. Now say after 2 years, you both agree that company is worth $50,000. And say now the company needs $10,000 worth of investment. Whoever invests that money should get 20% (10k/50k) of the company. Or each $1,000 will buy 2% in the company. Post this investment the equity division would be  First investor (you) 75% of 80% = 60 % Second investor (your partner) 25% of 80% = 20% Third (new) investor = 20% Now, if you alone decide to put all the money you stake will be 60 + 20 = 80% and your partner will be reduced to 20%. If you guys want to maintain equity as it was (75-25), you need to put money in the same ratio ($7500 and $2500). If you do that- First investor 60% + 15% (for $7,500) = 75% Second investor 20% + 5% (for $2,500) = 25%. Please know for IP-centric company valuation is very subjective. But, do make an effort to do the valuation at every stage of the company so that you can put a number in terms of equity for each investment.
