AskVinny, now sold under the name Vinny, is software for companies that rent out homes. The company calls it an AI teammate: a program built on large language models that reads incoming messages and acts on them as a member of staff would. It answers people who ask about a flat on WhatsApp, email, the website or the phone, books viewings, logs repair requests and chases rent. Its buyers are build-to-rent operators (companies that build blocks of flats only to rent them out), student housing, co-living operators and letting agents in the UK, Europe and Australia. It works inside the operator's property management system (PMS), the database where tenancies, rents and repairs are recorded.

Johnny Siu and Rory Buchanan, who met as early employees of the energy supplier Bulb, registered the company in London on 5 April 2024 with the early-stage investor Antler. A case study by CodeBase says the first version was a WhatsApp number that helped tenants fix boiler problems, which made money within hours but could not scale, so the founders moved to selling to large property operators. On 3 October 2024 an Antler partner wrote that AskVinny managed more than 1,200 properties and had £13,000 in monthly recurring revenue (MRR, subscription income that repeats every month), about US$17,048 at that day's exchange rate. Latka, a company database, records US$1M a year in revenue in June 2025 and names a founder webinar as its source.

Both money figures come from people around the company, not from a payment processor or a filed profit and loss account, so the grade is C: two dated figures from different sources that point the same way, together with growth from 1,200 to more than 10,000 units under management. The filed accounts show an average of 2 employees in the first year to April 2025, and Latka counted 9 people on LinkedIn in June 2025. The page also shows four earlier companies that tried to make renting simpler with software and failed.

AskVinny: US$1M a year in revenue, June 2025. AI teammate for rental property operators that answers renters and tenants, books viewings and logs repairs, United Kingdom, team of 2 to 10, evidence grade C.

How to read this table: a grade A value is the Federal Reserve's exchange rate. A grade B value comes from the UK company register (Companies House). A grade C value is a statement by the company, its investor, a support programme or a third-party database. A "calc" value was computed on this page from the rows above it.

Vinny plans in November 2026, from the company's pricing page (grade C). No prices are published.
PlanPer month, billed yearly (US$)Per month, billed monthly (US$)Limit
Standard1,000 tasks a month, existing integrations; price after a demo
Premium3,000 tasks a month, one custom integration; price after a demo
Enterpriseunlimited tasks and custom integrations, embedded deployment; price after a demo

The pricing page lists three plans by the number of tasks Vinny handles a month and asks buyers to book a 30-minute call for a recommendation. Standard and Premium include a guided 90-day setup; Enterprise adds a forward-deployed team of engineers and specialists. The sub-processors list names Stripe for subscription billing for self-serve signup, but no self-serve price was found.

03

Why did AskVinny work?

Four causes, in the order they mattered. Each one is a reusable lesson.

01

One job, on the channel tenants already use

The first version did one thing: it helped tenants with a broken boiler on WhatsApp. CodeBase reports that it made money within hours of going live. That showed the demand before the founders built anything broad.

02

From single landlords to operators

In 2024 Antler described a tool for landlords that removed agent fees. The founders found that large operators would not pay for a single fix and needed the whole rental cycle, so the product grew into leasing, maintenance, rent and renewals for companies such as Urban Bubble and Heimstaden.

03

Inside the existing systems, inside the rules

Vinny reads and writes the operator's property management system, customer database and inbox instead of replacing them. It follows written policies such as never agreeing a rent change, and passes a case to a person with the thread and photos attached. The sale is a saving of staff time, not a migration.

04

Sales as a repeatable process

Rory Buchanan told CodeBase that the first important hire was a business development representative for outreach, so that Johnny Siu could spend his time closing deals. New customers went from 1 to 4 a month. The team builds quick prototypes with Cursor during or after sales calls and lets the customer's reaction decide what to build.

How it was built

These details come from the company's sub-processors list (November 2026), its home page and the CodeBase case study. They are grade C. [6, 4, 3]

  • Language models: every request goes through OpenRouter, a gateway that sends it to one of several providers, here only EU-hosted OpenAI, Anthropic and Google models with zero data retention.
  • Voice: ElevenLabs runs the voice agents that answer phone calls.
  • Messaging: WhatsApp through the official WhatsApp Business API from 360dialog, with Meta's embedded signup to connect each customer's WhatsApp Business account. Twilio carries SMS, voice and an older WhatsApp path, and SendGrid sends email.
  • Hosting and data: AWS in Frankfurt (PostgreSQL on RDS and S3 storage), the web app on Vercel, background jobs on Inngest and real-time updates through Pusher.
  • Quality and operations: LangWatch traces and evaluates the AI answers, Datadog monitors the app, LaunchDarkly switches features on and off, Auth0 and WorkOS handle login and enterprise single sign-on, and Stripe handles identity checks and subscription billing.
  • Document search ran on Pinecone, a vector database, until 5 November 2026, when the list moved it to former sub-processors.
  • Signed leases go through DocuSign. The team builds sales prototypes with Cursor, an AI code editor.

Who tried this before AskVinny, and why did they fail?

Four companies in our database of failed startups tried to make renting or property management simpler with software. The values below are from that database and are not independently verified.

Died 2016 to 2019Burned US$2.7M

Castle

The promise

Property management for landlords, with technology for tenant messages, repair requests and rent collection.

Why it died

High customer acquisition costs and the difficulty of managing local service providers at scale, against established software such as Buildium and AppFolio.

Competition
Died 2011 to 2014Burned US$200K

Rentobo

The promise

One interface for landlords to list properties, screen tenants and manage applications.

Why it died

It could not stand out against larger companies such as Zillow and struggled to win users.

Competition
Died 2012 to 2017Burned US$13M

RadPad

The promise

Find an apartment, apply for the lease and pay rent from one phone app.

Why it died

A costly legal fight with Craigslist over alleged data scraping, and rent-payment fees that did not scale against Zillow.

Competition
Died 2015 to 2018Burned US$8M

Cribspot

The promise

Find and manage off-campus student housing, with leases, payments and landlord messages in one place.

Why it died

It could not stand out against Zillow and Apartments.com, or enter local markets that ran on personal connections.

Competition

The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.

What changed

The four predecessors sold software for renting when each new market needed local people, local listings or paid marketing, and they lost to larger companies such as Zillow, AppFolio and Buildium. Castle came closest to AskVinny's idea: it ran property management with technology and failed on the cost of managing local service providers.

AskVinny differs in two ways. First, it does not replace the operator's systems or staff: it works on top of the property management system and the messaging channels already in use, so the buyer saves time without switching. Second, large language models can read a free-text WhatsApp message about a leak, ask follow-up questions and raise the right job, which earlier companies needed people to do. The risks that remain are the old ones: larger competitors, and a market where every new customer still needs a sales process.

05

Can one person copy AskVinny now?

The enterprise product, no. The first step, yes.

The 2026 product needs integrations with many property systems, security certifications and a sales team, which one person cannot build quickly. The start can be copied: one repetitive job, a broken boiler, handled on the channel tenants already use and charged from the first day, then sold to companies that have the same job thousands of times.

Where it is still open: Rental markets outside the UK where tenants already message on WhatsApp, holiday-let and serviced-apartment managers, and facilities teams in office buildings and student halls.

  1. 1Pick one high-volume message type in one industry, such as repair reports, and handle it end to end on WhatsApp through the official WhatsApp Business API.
  2. 2Charge from the first week, and note which customers have the same problem at scale.
  3. 3Sell to operators with thousands of units rather than single landlords, and connect to the system they already use instead of replacing it.
  4. 4Make an early hire a salesperson who books demos, and show prospects a quick prototype built during or after the call.

What could go wrong for AskVinny?

The risks are the mirror image of the causes above.

What is not verified

The headline of US$1M a year rests on Latka, which gives "Founder, June 2025 Webinar" as its source. The webinar was not found or heard for this page, and Latka does not say whether the figure is recurring revenue. The earlier £13,000 a month is an Antler partner's statement of 3 October 2024. The filed accounts to April 2025 leave out the profit and loss account. A reader could look for the webinar recording, a seed-round announcement or a later founder post with a figure.

Competition

Latka lists EliseAI, Funnel Leasing, Zuma and Respage as competitors and calls AskVinny the smallest of the five by revenue; on this site the nearest stories are Eclectic AI, which answers shop customers on WhatsApp, and Fleety, an AI dispatcher for plumbing companies, and neither sells to landlords.

Dependence on model and messaging providers

The sub-processors list routes all language-model requests through OpenRouter to OpenAI, Anthropic and Google models, phone calls through ElevenLabs, and WhatsApp through 360dialog and Meta. A change in WhatsApp Business rules or prices, or in the EU-hosted models on offer, would reach the main channel directly.

A growing team, and who leads it

The accounts show an average of 2 employees in the year to April 2025; Latka counted 9 people on LinkedIn in June 2025, and the site now has a careers page and a forward-deployed team for Enterprise customers. Antler names Johnny Siu as chief executive and Rory Buchanan as chief technology officer; Latka lists Rory Buchanan as chief executive. Sales come from outreach by a business development representative and founder-led demos (CodeBase).

Mystery shopping and voice calls

The Enterprise plan includes an "Experience Audit" in which "The deployment team pose as prospects and residents at scale across your portfolio" to test the customer's own response times. Vinny's voice AI answers calls, and the pages read for this story do not say whether it tells callers that it is an AI; the home page says the company is compliant with the EU AI Act. Vinny also runs referencing and ID checks on renters, so it processes their personal data under GDPR.

From landlords to large operators

In October 2024 Antler described a product for landlords that removed agent fees. In 2026 the site sells to build-to-rent, student housing, co-living and letting teams, with prices only after a demo. Revenue per customer and churn are not published.
