Where Propstack honestly wins

Maturity & market establishment

10 years on the market, 3,000+ customers, enterprise references like Savills, RE/MAX, Sotheby's, and KENSINGTON. If you compete with similar firms and reference match matters, Propstack has an argument that VintAI as a younger boutique doesn't.

Deep ImmoScout24 integration

As a Scout24 subsidiary, structurally privileged — the ImmoScout24 connection runs deeper than third-party CRMs in the detail. If your business runs almost entirely on ImmoScout24 leads, that's a material advantage.

40+ out-of-the-box integrations

MS365, Google Workspace, DocuSign, Sprengnetter, Mailchimp, 3CX, Placetel — all available immediately without extra cost. With VintAI every integration is built on demand (upside: leaner; downside: not immediately available).

Where VintAI wins

Real code ownership

VintAI builds, then it's yours. Source code, documentation, data — all with you. You can hand it to another developer at any time or keep us on — your call. Propstack is pure rent: nothing is yours on day one, and nothing is yours on day X (when you leave).

Multilingual AI as a product core

Maria speaks German, English, and Russian natively — not via DeepL landing pages or translation plugins, but as CRM logic and a voice agent. Real-customer reference: Aleksei Sukmanov / A StandArt Real Estate Berlin uses this daily for international buyers. Propstack addresses German-speaking brokerage with language plugins, not multilingual brokerage as a product default.

Direct developer contact + 6-week money-back

At VintAI you talk directly to Michal, who builds your system. At Propstack you talk to sales and a customer-success manager — you never meet the developer who fixes a bug. Plus: if after 6 weeks of live operation your team isn't seriously using the system, you get your money back. Propstack: 14-day trial, then 12 months locked.

When which?

Choose Propstack if…

  • You're a 3–20-person brokerage that needs productive software immediately
  • Your business runs almost entirely on ImmoScout24
  • Your team is German-only, and your customers too
  • You prefer SaaS subscription over ownership
  • You accept a 12-month term and account-manager model
  • Enterprise references matter for your market

Choose VintAI if…

  • You work multilingually (especially DE/EN/RU)
  • You want AI telephony as a real product, not an add-on
  • Code ownership & data control matter to you
  • You're solo to ~5 brokers and Propstack seats don't pay off
  • You want direct developer contact instead of a sales layer
  • You value an honest 6-week money-back over a 14-day trial with a 12-month follow-on

FAQ on the comparison

Isn't VintAI more expensive than Propstack?
On entry, yes — Propstack costs €279 setup + €99 per seat/month, VintAI €6,000–15,000 setup + €250–600/month. But: Propstack is rent (SaaS), VintAI is ownership (custom build with source-code handover). At 5+ seats over 3 years total costs are similar on both sides — the difference is whether you own a system at the end or keep paying monthly.
Which brokerage should choose Propstack over VintAI?
If you're a 3–20-person brokerage running mostly on ImmoScout24, with a German-speaking team, and want a finished product immediately without a 3–4-week build phase, Propstack is the right call. Also if you compete with enterprise brands (Savills, RE/MAX, Sotheby's) in the same segment and reference-match matters.
Which brokerage should choose VintAI over Propstack?
If you work multilingually (especially with Russian- or English-speaking buyers in Berlin, Munich, Frankfurt), if you want AI telephony as a real product rather than a third-party integration via Placetel/3CX, if code ownership matters to you instead of SaaS rent, or if you're solo to ~5 brokers and Propstack pricing only really pays off at 3+ seats.
Can I migrate data from Propstack to VintAI?
Yes. Propstack has OpenImmo export and API access to your own data. We import leads, contacts, listings, and historical conversations once during setup. Migration effort is part of the 3–4-week setup phase, no extra cost.
Doesn't Propstack also have its own AI?
Yes — Propstack AI offers Voice-to-Listing, FloorScanner, Image Enhancement, and an AI SuperChat for WhatsApp centralization. These are bolted-on features on top of an existing CRM platform. VintAI is built the other way around: the AI assistant (Maria) is the core, the CRM is built around it. If AI telephony and multilingual lead qualification are your top requirements, an AI-native solution is usually smoother than a SaaS with AI add-ons.
What happens if I want to leave VintAI later?
You keep the source code, documentation, and all data. You can have another developer or agency continue work on it — there's no lock-in in the contract. With Propstack, leaving means you lose the system (SaaS without source).
Who builds VintAI?
Michal Andrzejewski from Berlin, building AI sales systems for DACH companies for years. Two CRMs currently live (Dubai + Berlin). At the first call you talk directly to the developer who'll build your system. At Propstack you talk to sales and a customer-success manager — Propstack has ~30 employees, so the developer doesn't know you.
