Turning LinkedIn engagement into people worth talking to.

Signl is a listening engine for LinkedIn. You point it at the profiles, company pages, posts and searches your buyers engage with, and it reads what everyone who comments or reacts actually said, checks them against your ideal customer, and hands over the ones worth contacting with a reason and a first line.

Engagement is easy to see and hard to act on. Sales teams were scrolling through likers and commenters by hand, guessing who mattered and writing every opener from scratch. The product had to make that judgement visible enough to trust, and fast enough to act on, without becoming another database to search.

My role

I co-founded Signl and own design end to end: the product and its design system, the app UI, and the public website at heysignl.com (opens in a new tab), which I also build in code with React and Claude Code. My co-founder Vlad builds the collection and qualification engine behind it.

Key decisions

  1. Show the reason, not just the score

    Every person arrives with the words they wrote, the post they answered, how they match the ideal customer and why now is the moment. A score alone asks people to trust a number; the evidence beside it lets them decide in seconds and write a message that sounds informed.

  2. Sources in, people out

    The backend can collect from far more than the UI shows. I kept the product to one model, sources go in, qualified people come out, and they go to the outreach tools the team already uses, so the app stays simple even as what it can watch keeps growing.

Outcome

Signl is live at heysignl.com (opens in a new tab), with a self-serve plan, integrations with HubSpot, Instantly, lemlist, HeyReach, Clay and Slack, and a remote MCP server so Claude, ChatGPT and other agents can work with a team’s sources and people directly. A redesigned homepage is ready to ship.

Selected screens

The redesigned Signl homepage: the headline “Find your next buyers on autopilot with Claude” over a sky background, with the app’s dashboard below.
The homepage section “Know why each person is worth a message”, with a lead’s comment, fit, reason to reach out and opening line.
The homepage section “Listen where it matters”, showing sources such as competitors and companies hiring flowing into Signl and out as people who fit.
The homepage section “Ask Claude who showed up today”, with the MCP setup beside a Claude conversation that finds and sends leads.
Signl runs as a remote MCP server, so the homepage shows the setup next to a real conversation rather than describing it.
Signl’s dashboard, with a prompt asking who you want to find and cards for the people ready to contact.
Signl’s Leads table, listing people with their signal, score, engagement, email status and an opening line.
Signl’s Signals view, listing the LinkedIn sources being watched with how many people each has found and how many are worth contacting.
Signl’s Analytics, with people found, qualified, sent and replied, and a weekly chart of found and qualified people.
Signl’s Agent page, with step-by-step setup for connecting Claude to Signl’s remote MCP server and the workspace’s API keys.
Signl’s ICP settings, describing the business, the ideal buyers by job title and seniority, and the target companies.
