50 Top Apps, SaaS Solutions, Services and Sites for Startups

Founders and CEOs are very demanding when it comes to the tech they use to run their businesses. They have high expectations. They should, too. See how this list of apps, SaaS solutions, services, and sites lines up with your tech stack and hopefully get some new ideas for what to add or switch.

I hope you find this list helpful - I'm John Gauch, an operating partner to founder-led companies. As a fractional COO, I provide growth and operations support to founders who want to make a big leap forward with their business and need to add capability or capacity to the team to make it happen.


Updated September 3, 2026, including vetting for recent AI developments.

What started as a list of 50 company apps has grown well past that figure, and I keep adding to it.

I personally don’t find lists or infographics of every possible option for a problem super useful. I don’t need another time-sucking To Do, to evaluate all of the choices. I want to know what’s a reasonably safe bet, get started with it and turn back to the business of growing my company.

With regard to each product on my list, I've either used it, and I recommend it, or someone I know and trust has used it, and they recommended it to me. The list is for Seed to Series A companies and other growing small businesses. This is where I spend most of my work time, but it also includes products for brand-new companies (drawn from the mentoring and venture studio work I do).

Feedback is invited: If you feel like something should be added, or if you have used one of the products and had a negative experience, email me to let me know.

I don’t mention project management tools (e.g., Asana, ClickUp, Monday, Trello) because everyone seems to have a favorite, and they are all reasonably decent. I use Trello for my personal task tracking. I wouldn’t spin too long trying to ascertain which one of them is the “best.”

Again, if your choice of a new SaaS app for your startup tech stack is not going to make or break your business, don’t over-index on it. Do some quick research. Get together a couple or a few ideas. Do a brief analysis. Pick one and turn back to the activities that are going to be far more impactful on your company and its success.

That’s the benefit of having a list like this. I hope it helps.
