Vlad from Kagi here. We are very close to breakeven currently, with 4+ years runway with current spend and it gets better every day. Budget for shirts was allocated months ago.
Kagi is slightly different than other SV startups in how we approach things because of the freedom given by being (nearly) completely bootstrapped and built with sustainability in mind since day one. Some companies buy ads to attract new customers, we buy tshirts to show gratitude to existing. We also reinvest any savings we make into lowering the price and increasing the value of the product (check our product velocity in release notes [1]). Our customers propelled us to where we are through word of mouth, it makes sense to keep investing in nurturing that relationship. And having 20,000 doggos walk around the earth soon is fun.
Winning in search is a marathon, not a sprint. We might as well enjoy the run.
