Ascero AI builds custom voice agents and workflow automation for restaurants operating in the Bay Area metro (4,750,000 residents, roughly 156,000 small businesses, ACS-derived median household income around $124,000). Founder-led, flat-fee Foundation tier at $4,000/month, BAA executed where required, live in two to four weeks depending on vertical.
Independent restaurants miss an estimated 38% of inbound calls during dinner service. The hostess is plating water, the manager is on a vendor call, and the phone keeps ringing — straight to a voicemail no one checks until close. Each missed call is roughly $35 to $90 in walked takeout revenue, $80 to $180 in reservation cover, and $1,200 to $8,000 in private-dining inquiries that go to the steakhouse down the block. The Ascero AI receptionist for restaurants picks up in under two rings, handles English and Spanish out of the box, books reservations into OpenTable / Resy / Toast, takes takeout orders against your live menu, flags allergens, and escalates private-event inquiries to the GM with full context.
what San Francisco restaurants are leaving on the table
The Bay Area metro has roughly 156,000 small businesses, a figure derived from US Census County Business Patterns and Business Dynamics Statistics at the MSA level. The dollar figures below are an illustrative worked example, not a measured San Francisco statistic — they exist to make the math concrete, and every input is stated so you can swap in your own numbers.
Illustrative estimate — assumptions shown, not a measured figure
The agent does not need to be perfect — it needs to be better than voicemail. The per-business figures we actually stand behind, with sources, are below.
A 90-seat full-service restaurant doing $4.2M annual revenue, missing 38% of inbound calls, with an average ticket of $52 and 110 inbound calls per day: roughly 42 missed calls daily, of which 60% would have converted = $1,310/day, or roughly $477K annually in recoverable revenue. Even at a 35% recovery rate, that's $167K back to the P&L on a $48K subscription.
the San Francisco context
SF SMB operators are exposed to the most demanding customer base in the country on phone interactions — the same engineers who build voice models are calling for restaurant reservations and expecting better-than-human performance. Voice agents here are graded harshly and tuned aggressively.
Ascero AI is founder-led from Waltham, Massachusetts. Both co-founders (Kadin Nestler and Jaiden Lawlor) build into customer calls directly — the discovery, prompt design, and tuning loop is run by the same people who close the deal. For San Francisco restaurants that is meaningful because the phone-handling tuning that wins is vertical-and-region specific (a San Francisco restaurants's ideal triage is not the same as a generic national template), and we ship those refinements monthly. US-based, no offshoring, no contract receptionist resellers — the people you talk to are the people building the agent.
Pricing is flat: Foundation tier at $4,000/month with a one-time $2,500 setup fee, unlimited inbound minutes, monthly tuning included, and 30-day cancellation. No annual contract, no per-call fees. No PCI scope — the agent never reads or stores card numbers (it sends a one-time Stripe / Square payment link instead). No alcohol sales (state liquor law: the agent flags wine pairing questions but refuses to take a phone order for alcohol). Call recording disclosed in the house greeting per single-party-consent and two-party-consent state requirements. If you are a member of the local chamber (www.sfchamber.com), ask about the chamber-member referral discount.

frequently asked — restaurants in San Francisco
It handles full Spanish conversations — order-taking, allergen confirmation, reservation booking — natively, not via translation. The voice agent runs on a Spanish-fluent voice model and uses Spanish-trained menu and modifier vocabulary. Roxanne's Taqueria demo handles end-to-end Spanish takeout orders.
Toast, Square, Clover, and Lightspeed are native integrations. Resy, OpenTable, SevenRooms, and Tock are native for reservations. For any combination not listed, we run a 7-day discovery to confirm — most modern POS APIs are workable.
Under two rings on every inbound call, 24/7. There's no "all our hosts are busy" hold. The agent never asks the caller to leave a message.
It transfers to a designated human cell (typically the manager or owner) with a structured summary of what the caller was trying to do. We tune the prompts monthly based on the actual call corpus, so the no-match rate typically drops below 4% within 60 days.
It does not take card numbers verbally — that creates PCI scope. Instead, it texts the caller a one-time Stripe or Square payment link with the order pre-loaded. Caller pays in three taps, order drops into the POS queue.
