I'm David, the founder of Echosig 👋
Originally from Sweden 🇸🇪 and now based in Munich, Germany 🇩🇪, I built Echosig because I was tired of fixing email signatures manually. One too many times, I found myself copy-pasting HTML into Outlook for the 47th time and thought: there has to be a better way.
Solopreneur
Just me. No team, no investors, no committees. Every decision comes back to one question: does this actually help you?
Solodev
I write every line of code myself. Fast fixes, real features, no "we'll add it to the roadmap" excuses.
Privacy-First
Built in Germany, hosted in the EU. GDPR compliant by default, not as an afterthought.
User-Focused
Every feature exists because someone needed it. I build what solves real problems, not what looks good on a feature list.
The problem was obvious:every time someone joined the team, changed roles, or the company rebranded, I'd spend hours updating email signatures across Gmail, Outlook, and Apple Mail. Copy. Paste. Fix broken images. Repeat.
I looked for a solution. Found enterprise tools that cost a fortune and required IT departments to implement. Found "free" tools that added watermarks or relied on ad-based monetization. Found nothing that just worked without the hassle.
So I built Echosig.
Echosig is simple by design: design a signature template, share a magic link with your team, and let everyone generate their own properly-formatted signature in seconds. No HTML knowledge required. No IT support tickets. No more copy-pasting from one account to another.
With 25+ years in marketing and tech, including multiple startups, two IPOs, and an exit to a NASDAQ-listed company, I've seen how the right tools can save incredible amounts of time. This is the tool I wish I had.
Building this solo meansI feel every bug personally, celebrate every signup, and read every support message myself. There's no support team to deflect your feedback, no product manager to filter what reaches the developer. When you reach out, you're talking directly to the person who wrote the code.
Have a feature idea? Found a bug? Just want to chat? Reach out anytime. I read every message.
