This post is for non-technical founders and domain experts who have a great idea or see potential for improving their work with tech. You might be unsure whether your idea makes sense or how to approach it. You may also need someone on the technical side to support you. Whether you have just an idea or already have a vibe-coded prototype, both are fine starting points.
I’m an engineer, the classic technical co-founder. This post covers how to prepare and stand out when looking for people like me. It also explains the options for early-stage technical help.
How to prepare
Build a prototype, through vibe coding or with freelancers. This will make you stand out. Even if the prototype is rough, it will be much better at communicating your idea than a description alone, and it shows that you have taken initiative. With modern AI tools, this is more accessible and an increasingly common way to communicate ideas. Focus on a narrow slice of your idea or product: the unique feature that can be the wow effect. You can ignore feature parity with existing solutions and production-level stability, but make sure the core idea works.
Have a solid idea and show that you know what they don’t: your business plan, go-to-market strategy, customers, domain expertise. That shows competence. You do not want to be someone who only contributes an idea. Engineers also have endless ideas. They need someone to handle the business side, and that is not “having an idea”. That means managing a company and bringing in money. You may handle product development too, but marketing and go-to-market strategies will definitely be part of your role.
Ideally, have a short pitch deck or document to share. Engineers (well, me at least) hate “quick calls” without anything to read or prepare beforehand. Make sure that pitch shows the business knowledge described above. Describe your idea concretely, with a focus on the business side. How will you make sure this product fits the problem? Explain your advertising and go-to-market plans. Where will the revenue come from? What are the equity and work expectations? Bonus points if you share that document beforehand.
“But wait, what if they steal my idea?” This is a common fear, but an idea alone does not build a business. Execution counts. If an engineer wants to work with you, they may not be able to or may not want to handle the business side of the execution themselves. Also consider that your pitch should focus on execution anyway: how you will go to market and make money. The idea is only part of it. If you want to keep your idea secret until someone signs an NDA, you will not find a partner.
Options to find technical partners
The first and easiest option, if you have the budget, is to hire professionals. Some technical people offer part-time help to guide technical decisions and build prototypes. These are often described as “fractional” roles. For this kind of technical partner, search for people who offer “fractional CTO” (chief technology officer) services or similar roles, such as “fractional engineer” or “fractional software engineer”. You pay for their time and expertise. A co-founder relationship would be a separate agreement.
Another option along the same path is paying an agency to guide you. Make sure that you are spending your time wisely and talking directly to a technical person. Avoid spending too much time defining complex engagement letters and prototype scopes before you have tested the idea. Instead, search for a small agency specialised in startup support that works in an agile manner, showing you working prototypes early and improving them with your feedback. With small agencies, you can often have one person as your point of contact who keeps the context and is your technical partner long-term.
As an example, we at isselthal specialise in supporting domain experts and non-technical founders with technical expertise. We also provide fractional CTO services and engineering capacity for early-stage startups. We can help you build up in-house expertise too. Read more about how we help individual founders such as domain experts or non-technical founders exploring an idea. Or, if you are further along, read about how we help early-stage startups. You can also contact us for a discussion of your idea.
The second option is to get involved in the startup ecosystem. Web-based portals exist specifically to match technical and non-technical founders. One place to start is Y Combinator Co-Founder Matching, run by the startup accelerator Y Combinator. YC also runs Hacker News, a community with a strong technical focus. Its co-founder matching platform is a place to look for technical people interested in finding business co-founders.
Another good way is to get involved in your local startup accelerator or startup center. Some are commercial or attached to venture capital companies. Others receive grants from public institutions. University-based centers support students and faculty in bringing their research results into industry. Examples of startup hubs are ZOLLHOF in Nuremberg and STATION F in Paris. For an example of a university-based project, see the Start-up Center at FernUniversität in Hagen. Often, these places host events where you can meet others interested in entrepreneurship and get in contact with technical people who might like your idea. The startup centers may also be able to guide you to local resources or connect you with the right person.
As a more long-term approach that can be rewarding in itself, go to spaces where engineers are and join in. One good way to do that is to look for open-source projects in your domain of expertise. Contribute your domain knowledge rather than starting by using AI tools to vibe-code solutions or promoting your startup idea. Think about what tools and programs you use in your field of expertise. Find out whether they are open-source and accept contributions. If they do, look for problems where your domain knowledge could help. Or search on open-source platforms such as GitHub for projects in your domain, get familiar with them, and become a productive contributor. The engineers involved in these projects will notice your contributions and become more receptive to working with you or giving you technical feedback. They probably also know other technical people whom they can recommend to you.
You can also find a hackathon close to you or with a topic that interests you and join. Hackathons are often organised by the startup support organisations described earlier, universities, or sometimes public institutions such as local municipalities. During a hackathon, you can meet technical people in a relaxed environment and get a feeling for how they work and whether you are a good match personality-wise. If you choose a hackathon with a topic that interests you, it can also be a lot of fun. A topic related to your startup idea gives you a shared interest with the technical people in attendance. You can contribute at hackathons without a technical background. Domain experts can help teams guide the development of a prototype in a useful direction.
How to approach technical people
Write a short, concrete first message. Explain the problem, who has it, and why you know this domain. Share the pitch document you prepared. Say whether you are looking for feedback or paid help with a prototype. If you want a technical co-founder, say that.
If you have a prototype (great!), explain that you made it for communication and exploration, and that you don’t expect the engineer to just extend it. Show what it demonstrates and where you are unsure. Give them room to suggest a different technical approach.
Try not to be over the top. To engineers, grand promises and absolute certainty that an idea is genius come across as naive. Being aware of risks and potential problems shows your competence. You do not need to have every answer, but you should be able to explain what you have tested and what you still need to find out.
Make the next step easy. Ask whether they would like to discuss the idea after reading your document. If you are looking for a co-founder, discuss time commitment and equity expectations early. Try working together on something small before making a long-term commitment.
Good luck! If in doubt, contact us. We can help ;)
