Talk to your customers
before they're customers.
Lighthouse runs voice interviews with your prospects — the people you're trying to win — and returns a Jobs-to-be-Done report. Validate the problem before you build, pitch, or launch.
Every founder, PM, and investor knows they should validate with prospects before building.
Almost none of them do.
Three reasons it doesn't happen. They're the same three reasons every time.
Scheduling thirty prospects is hell.
Ten Calendly invites, six no-shows, two reschedules. By the time you've booked the conversations, you've burned a week and the conviction is gone.
Designing the interview is hard.
Mom Test rules are easy to read, hard to follow live. Most founders drift into pitching, leading, and gathering compliments.
Synthesizing thirty transcripts is exhausting.
Even when the calls happen, the sense-making doesn't. The transcripts sit in a folder. The build continues on vibes. Eighteen months later, the company runs out of runway.

Four steps from "I should talk to prospects" to "here's the JTBD synthesis."
Create a project
Name your research goal. Describe the persona you want to talk to. Two minutes.
Drop seed questions
Three to five things you want to learn. Lighthouse generates a Switch-Interview-style guide from them.
Send the link
One URL. Drop it in a cold email, a LinkedIn DM, an SMS to a warm lead. Prospects tap it on their phone and talk.
Get the report
Once interviews complete, Lighthouse synthesizes a JTBD report: forces, segments, the five quotes you must read, recommended actions.

A link is only useful if a real human taps it. Here are the templates we use to make that happen — written like a sales founder, not a marketer.
- {{first_name}} — quick research ask
- {{first_name}} — 10 minutes, no pitch
- {{first_name}}, before I build the wrong thing
Hi {{first_name}} —
I'm building {{one-line product}} for {{ICP segment, e.g., "solo consultants who hate scheduling"}}, and you fit the persona almost exactly.
Before I write a line of code, I'm trying to talk to 25 of you. I built an AI interviewer so you don't have to find a calendar slot — 10 minutes, voice or text, on your phone, whenever:
{{lighthouse_link}}
I'll send you the synthesis after. No pitch, no list, no follow-up unless you want one.
— {{your_first_name}}
{{first_name}} — building something for {{ICP segment}} and you're one of 25 people I want to learn from before I ship.
10 min AI interview, voice or text, on your phone:
{{lighthouse_link}}
I'll share what I learn from all 25.
No pitch.
Hey {{first_name}} — Casey from {{prior_context}}. Building something I think you'll have strong opinions on. 10 min on your phone, no scheduling: {{lighthouse_link}}
- 10–25%Cold list, well-targeted ICP, named human in subject and opener.
- 30–45%Warm intro from a peer, or your own waitlist / past pilots.
- 50–70%People you've talked to once before — second touch with a clear ask.
Drop the link to 50 named humans who match your ICP — not 500 strangers. Lighthouse rewards specificity. The interview only generates signal if the people on the line could plausibly write you a check someday.
Built for the people who need to validate before they build.

Why did you build this?
Why this exists.
We built Lighthouse because we kept watching founders we love ship product based on vibes — and lose eighteen months because they never talked to the people they were trying to win. The prospect calls never happened. Not because the founders didn't care, but because the friction was real. Scheduling. Designing the interview. Synthesizing the answers. Three full-time jobs crammed into the cracks of an already-impossible week.
Lighthouse removes the friction. The conversations happen. The fog lifts. The build sharpens before you spend the next six months on the wrong thing. That's the whole pitch.
