LobbyStack is live

Most small businesses do not lose customers because they do bad work. They lose them because the phone rang while everyone was already doing the work.

Today, LobbyStack is live.

LobbyStack is an open-source AI receptionist for businesses that depend on calls, bookings, quotes, and fast follow-up. It answers when your team is busy, closed, driving between jobs, or already helping another customer.

The point is not to make phone support feel futuristic. The point is simpler than that: a good caller should not become a missed opportunity just because they called at the wrong time.

Voicemail is not a workflow. LobbyStack is our answer to that.

What it does

LobbyStack sits between your business phone and your team. You decide when it should answer: every call, after hours, during busy periods, or only when nobody picks up.

When a caller reaches LobbyStack, it can:

• answer questions from your business knowledge
• capture caller details like name, number, service need, location, and urgency
• book appointments from your calendar availability
• send confirmations and summaries by text or email
• transfer urgent calls to the right person with context attached
• follow up on missed calls, quote requests, reminders, and callbacks
• keep the record with transcripts, recordings, summaries, callers, and outcomes in one dashboard

It is not trying to replace the people who run the business. It is there to cover the moments when those people are with customers, closed for the night, or finally trying to eat lunch without holding a phone in one hand.

Why we built it

The old options never felt quite right.

A call tree is cheap, but customers can feel it fighting them. A voicemail box is familiar, but it asks the caller to do the work and hope someone gets back to them. A human answering service can be helpful, but it is often expensive, hard to customize, and disconnected from the details your team actually needs.

AI changed what is possible, but a lot of AI phone tools still feel like demos wrapped in a pricing page. They answer the call, sound polished for 30 seconds, and then break down as soon as the caller gets specific.

Small businesses need something more practical than that. They need a receptionist that knows the business, follows instructions, books the appointment while the caller is still interested, and gets out of the way when a human should step in.

That is the shape of LobbyStack.

What makes it different

LobbyStack is not a chatbot strapped to a phone number. It is a receptionist stack for calls that need an outcome.

It is built around control, not magic.

You add the knowledge your receptionist should use: services, prices, hours, policies, locations, staff instructions, FAQs, and the details callers ask about most. You can also tell it what not to say, when not to book, when to transfer, and when to schedule a callback instead of guessing.

That matters because real calls are messy. People interrupt themselves. They ask two questions at once. They change their mind halfway through. They give the address before the service type. A rigid flowchart handles that badly.

LobbyStack lets you describe the outcome in plain language:

If someone asks for pricing, collect the service type, location, budget, and timeline. Share the approved price range when one exists. If they need exact pricing, schedule a callback with sales.

That is closer to how you would train a person, and closer to how your team already thinks about the work.

There is another difference: LobbyStack does not make you pay for junk. Spam calls and calls under 10 seconds do not count against your plan, because nobody should be billed for wrong numbers, robocalls, or instant hang-ups.

Open source by design

LobbyStack is open source because phone calls contain real customer data, and businesses should not have to treat their front desk like a black box.

For many teams, the hosted version is the fastest way to get started. Create an account, connect the pieces, add your business knowledge, and go live.

For teams with stricter privacy, compliance, or infrastructure needs, self-hosting is part of the product, not an afterthought. You can run LobbyStack on your own server, keep tighter control over customer data, and adapt the system around your own operational requirements.

That is a major difference from most receptionist software. We do not think trust should depend on a vendor asking you to take everything on faith.

Built for the calls that actually decide revenue

The first version of LobbyStack focuses on the everyday calls that decide whether work gets booked:

• a new customer asking if you serve their area
• someone trying to book, reschedule, or cancel
• a caller asking about prices, hours, or policies
• a lead who needs a quote before they commit
• an urgent request that should reach a person now
• a missed caller who should not have to call three competitors next

These are not edge cases. They are the ordinary calls that fill calendars, start estimates, rescue jobs, and keep customers from drifting to whoever answered first.

Start small, then grow into it

You can start with the Free plan, test real calls, and see whether LobbyStack fits your business before putting it in front of more customers. The Pro plan is designed for production call coverage with transparent usage-based billing, and Enterprise is available for higher volume, multiple locations, custom routing, or self-hosted implementation support.

Three things matter most in this first release:

• Callers get an answer instead of a voicemail box.
• Your team gets the summary, context, and next step.
• The business stays in control of what the AI can say and do.

We are live now, and this is still the beginning. The product will keep getting better around the same promise:

Answer the call. Understand the customer. Take the next useful step. Keep the business in control.
