Property management software company AppFolio recently announced its AppFolio Stack offering, which it bills as an "integration marketplace." Still relatively uncommon in proptech, it's an approach that has become a standard marketing and business development strategy in the greater software industry.

As the company claims, "AppFolio Stack resolves the integration challenges previously unaddressed by legacy real estate solutions, empowering property managers of all sizes to boost productivity, simplify workflows and improve resident experiences." Third-party vendor partners include ButterflyMX, Conservice, HappyCo, Knock, Lowe's, and Property Meld.

"As we partner with operators with larger, more complex portfolios, we consistently hear about the need for better technology that unifies specialty PropTech solutions within a single, modern platform," Will Moxley, the company's senior vice president of product, said in prepared remarks. "Simultaneously, small, high-growth property management companies are looking to increase their productivity by leveraging the latest technology. With the launch of AppFolio Stack and our certified integration approach, we provide the real estate industry an alternative to legacy property management platforms and their limited integrations, while protecting our customers against the risks of poorly implemented and unvalidated integrations. This enables property managers of any size to finally deploy the modern technology stacks that give their businesses a competitive advantage."
