I'm David, the founder of Echosig 👋
25+ years in marketing and tech, including multiple startups, two IPOs, and an exit to a NASDAQ-listed company. I built the tool I always wished existed.
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.
Founder-led and deliberately focused
Echosig is run by David Klein in Munich. That means direct accountability, careful product decisions, and support from the person building the product.
Built close to the customer
Customer feedback goes straight into product decisions. There are no layers between the people using Echosig and the person responsible for improving it.
Privacy-first, not as an afterthought
Built in Germany, hosted in the EU. GDPR compliant by design, so you don't have to think about it.
Built on real problems, not feature lists
Every feature in Echosigexists because someone needed it. If it doesn't solve a real problem, it doesn't ship.
Why I built it
Email signatures sound trivial — until someone joins the team, changes their title, or the company rebrand hits. Suddenly you're spending hours updating signatures across Gmail, Outlook, and Apple Mail. Copy. Paste. Fix the broken image. Repeat.
I looked for a solution. Found enterprise tools that cost a fortune and required an IT department to implement. Found "free" tools that added watermarks or survived on ad revenue. Found nothing that just worked, without the hassle, for a reasonable price.
So I built Echosig.
Design a signature template, share a magic link with your team, and everyone generates their own properly-formatted signature in seconds. No HTML knowledge required. No IT support tickets. No more copy-pasting from one account to another.
When you reach out, you're talking to me, the person who designed the interface, wrote the code, and will push the fix. There's no support team to deflect your message, no product manager between you and the developer.
Every customer message is read directly, and early customers help shape the product with practical feedback from real rollout situations.
