Linéa AI
Voice AI that answers restaurant calls and takes orders
How are you getting your first B2B clients when your buyer is genuinely hard to reach digitally?
I'm building Linéa AI, a voice AI agent that answers restaurant phones 24/7 (pizzerias, kebabs, fast food) so orders and reservations don't get missed during rush hours. Solo founder, still pre-first-client, but I have a few qualified inbound leads in the pipeline.
The hard part isn't the product — it's reaching the buyer. Independent restaurant owners barely check email, don't really use LinkedIn, and are genuinely busy running service. What's worked for me so far:
- Cold-calling and walking in during off-peak hours
- Monitoring public business registry filings (BODACC in France) to catch restaurants that just changed hands — new owners are more open to changing how things run
- Facebook groups, since that's actually where a lot of restaurateurs hang out, not LinkedIn
It's slow and very manual. For anyone who's sold to a similarly "offline" or old-school local business audience (not SaaS-native, not on LinkedIn) — what actually moved the needle for you to land your first paying customers? Curious if there's a channel or a framing I'm missing.
Quick update. Someone recently asked me a good question: how will I know when Linéa is reliable enough to trust with real orders?
I don’t have a full answer yet, but I made progress on part of it today — added two automatic safety checks. If the voice agent doesn’t respond to a call, it now falls back to a backup number automatically. And there’s a check that compares confirmed orders against actual kitchen tickets printed, so if something silently fails, I get alerted immediately instead of finding out from an unhappy customer.
Still no signed client, still nothing “proven” in the sense of real-world volume. But this is the kind of thing I’d rather build now, before I have paying customers, than scramble to add after something breaks.
Hey everyone, quick intro since I haven’t properly done one yet.
I’m Jules, 16, based in France. I’ve spent the past few months building Linéa AI — a voice assistant that answers restaurant phone calls, takes orders in natural French, and sends them straight to the kitchen printer. Built for pizzerias, kebab shops, and fast food places, where a missed call during rush hour is a lost order, not just an inconvenience.
Right now I’m in the early prospecting phase — mostly walking into restaurants in person and demoing the assistant live on their own number. No signed client yet, working on my first one.
One thing I could genuinely use help with: if anyone here has contacts in the restaurant or fast food industry in France — an owner, a franchise manager, someone in a restaurant tech company, anyone — I’d really appreciate an intro, even just to talk and get feedback. Trying to widen my network beyond cold walk-ins.
Happy to answer questions about the tech, the sales side, or building solo at 16 in the meantime.

Love the hustle — walking into restaurants and demoing live on their own number is such a smart way to show value instantly. At 16 you're already ahead of most founders on sales grit, keep it up!

Thanks! Honestly the live demo part is what convinces people fastest — way more than any pitch I could give.

Building a voice AI at 16 and doing live demos on their actual phone lines is seriously impressive—that's more hustle than most people twice your age. If you haven't already, try reaching out to local restaurant suppliers or POS resellers; they talk to owners all day and might be your fastest shortcut to warm intros.

That’s a genuinely good idea, thank you — hadn’t thought about POS resellers specifically. Going to look into who covers my area and try reaching out. Really appreciate the tip.

I’m 16, based in France, and I’ve spent the last few months building Linéa AI — a voice AI that answers restaurant phone calls 24/7, takes orders in natural language, and sends them straight to the kitchen printer.
The idea came from noticing how many independent restaurants (pizzerias, kebab shops, fast food places) lose orders every day simply because they can’t answer the phone during rush hour. Existing solutions were either generic voice assistants that don’t understand food orders, or too expensive for small restaurants.
I’m currently onboarding my first restaurants in the Paris area. Happy to answer any questions about the tech stack, going solo at 16, or anything else — would love feedback from this community.

What stands out to me is less the tech and more the sales motion — convincing an independent restaurant owner to trust an AI with their phone line is a hard sell even without the "I'm 16" factor. How are you actually getting the first restaurants to say yes? Cold walk-ins, personal network, free trial period? That part seems just as hard to crack as the voice tech itself.

Honestly, right now it’s almost entirely cold walk-ins — I go into pizzerias/kebab shops in person (I’m based in France) and offer to demo the assistant live, right there, calling their own number with their actual menu, rather than asking permission first and pitching abstractly. That live demo does most of the convincing.
I’ve also started sourcing leads from BODACC — a French public government register of business filings, including recent restaurant ownership changes. New owners tend to be more open to changing how things run than someone who’s had the same setup for 10 years. I cross-reference that with public professional directories (like PagesBlanches) to find the actual manager’s name and listed business contact before reaching out, rather than just calling the generic restaurant line.
No free trial yet, that’s honestly a gap I know I have compared to some competitors. My most advanced deal right now is still just a scheduled call, no signed client yet, so I don’t want to oversell how solved this part is. Honestly, the sales/outreach side has turned out to be at least as hard as building the voice tech itself — maybe harder, since the tech I can just keep improving alone, while getting a stranger to trust you with their phone line requires them to say yes.

Love the BODACC angle — sourcing leads from ownership changes instead of cold-calling blind is smart. The live-demo-on-their-own-menu trick is gold, might steal that idea for Ehugapy. Good luck landing that first signed client!

The strongest part is the wedge: missed phone orders during rush hour are a direct, measurable revenue problem for restaurants. The key question now is whether Linéa can handle the messy edge cases of real food orders reliably enough to earn a restaurant's trust.

That’s exactly the right question, and I don’t have a fully proven answer yet since I haven’t signed a paying client. What I can say: the assistant is configured with the restaurant’s actual menu and real options (sizes, sauces, supplements) rather than a generic template.
Before ever testing it live with a restaurant owner, I stress-tested it myself with a bunch of fictional menus, throwing tons of edge cases and messy orders at it deliberately. It did make mistakes early on — I went through and fixed each one as I found it. Since then, testing it regularly, it hasn’t made an error in a while.
I also test it live with the owner during the demo so they can throw real orders at it themselves before deciding anything. If it hits something outside what’s configured, it transfers to a human instead of guessing. But the honest answer is: reliability at scale, across many different restaurants and real customers, is the thing I still need to prove and not claim.

That makes sense. I’d be interested in continuing the conversation a bit more—what’s the best email to reach you at?

"Restaurant owners barely check email, don't really use LinkedIn" — exactly. But someone already has their trust and their phone numbers: the POS resellers, food suppliers and equipment reps who walk into those kitchens every week. That's your channel, not inboxes.
I hand-build prospect lists for founders. Want a free starter batch — Paris-area spots matching your ICP plus a few POS/supplier reps worth partnering with? No strings.
That's a really good point actually, I hadn't thought about POS resellers and equipment reps as a channel — they already have the access I'm trying to build from scratch. I'll take you up on the free starter batch, thanks.
