The origin of Second Nature is satisfyingly unglamorous. In 2012, North Carolina State University students Thad Tarkington and Kevin Barry found themselves confused by the chore of buying an HVAC filter. The sizes were peculiar, the replacement schedule was forgettable, and the product spent its useful life hidden behind a grille. They saw a subscription where everybody else saw dust.
The company they started, FilterEasy, mailed the right filter to a customer's door at the right interval. It was a classic wedge product: cheap compared with the machine it protects, recurring by nature, irritating to remember and wonderfully dull. The pair left school, worked from a garage and, by the company's own telling, subsisted for a while on ramen and peanut butter. A few hundred early subscribers became hundreds of thousands as FilterEasy added partners and funding.
Today, the filter is still in the box, but the box has swallowed half the resident lifecycle. Second Nature sells property managers a Resident Experience Platform that combines guided onboarding with a managed package of insurance, credit reporting, filter delivery, pest control, rewards, identity protection, move-in help and group-rate internet. Maestro, its orchestration software, decides which documents, prices, tasks and choices a resident sees according to the property, market or resident profile.
The first thing that stopped fitting was the name
FilterEasy did what it said on the label. That precision became the problem. In 2019, the founders renamed the business Second Nature after an internal exercise about creating more customer value. The team wanted room to move beyond air filtration into home wellness. Tarkington later explained that the company was looking five to 15 years ahead: keeping the old name would create a brand disconnect as new products arrived. The short-term pain of a rebrand looked cheaper than the long-term ceiling.
The more consequential change was not cosmetic. The direct-to-consumer company discovered that professional property managers were a distribution channel and a richer source of problems. A homeowner needs a filter every few months. A manager of hundreds or thousands of homes needs filters, proof of insurance, fewer midnight pest calls, smoother move-ins, clearer leases and some reason for a resident to renew. Solve those together and the filter becomes an anchor for a service bundle.
This was not a clean pivot away from the original idea. It was an accumulation. The company followed one physical reminder into adjacent chores, then built software to coordinate them. That sequence matters. A filter arriving on the doorstep is visible in a way that back-office automation is not. Second Nature says more than one million residents have experienced filter delivery, and calls the tangible product a cornerstone of perceived package value.
One box became eight resident services
The customer buys less work; the resident buys the bundle
Second Nature's customer is the property manager, but its payer is often the resident. The manager selects a package, attaches it to new leases and renewals, and collects a monthly fee alongside rent. Second Nature says residents typically pay between $20 and $80 a month, depending on the services and market. After benefits are delivered and the resident pays, Second Nature invoices the manager. The manager keeps a margin. The upfront commitment is a refundable $500 deposit rather than a large implementation fee.
The company calls this success-based pricing. It is also smart risk allocation. Property managers avoid paying before a lease produces revenue, while Second Nature gains recurring volume without having to acquire every renter individually. For managers, the sale is operational relief as much as a bag of perks. Insurance tracking, filter schedules, resident questions and vendor coordination move to an outside team that integrates with existing property-accounting software.

The named customer list spans large operators and local firms: Greystar, Roofstock, Evernest, HomeRiver Group, Progress Residential, Invitation Homes, PURE and Birdy Properties appear in company materials. RHOME uses group-rate internet across a portfolio of more than 50,000 units in over 40 markets. Birdy says guided onboarding cut three days from its leasing process. These are vendor-reported results, useful as evidence of the product's shape rather than a universal promise.
Maestro turns the lease into a storefront
A benefits bundle can be copied. The harder part is activating the right bundle at the right property without creating another administrative swamp. Maestro is Second Nature's answer. It connects to property-accounting systems through APIs, maps custom fields and ledger codes, and lets managers assign documents, charges and workflows with conditional logic. Residents receive a mobile-first path by text or email rather than a static handbook dropped into a portal.
That changes onboarding from paperwork into a commercial moment. A resident with a dog can see relevant terms. A home with an unusual HVAC system can receive the correct filter option. A property eligible for a particular internet provider can display that service. Second Nature says 25 percent of residents offered this kind of choice upgrade at least one benefit. Personalization makes the package more useful, but it also raises revenue per lease. The friendly experience language sits on top of precise merchandising.
AppFolio noticed. In April 2025, the public property-management software company paid $75 million for a minority, non-controlling interest in Second Nature's parent and announced a strategic partnership. The companies then put Second Nature services into the AppFolio ecosystem, including Resident Onboarding Lift. By late 2025, AppFolio was presenting the product to investors as a way to activate services during move-in and create new revenue streams.
The investment did not disclose Second Nature's valuation or revenue. It did reveal strategic weight. AppFolio serves tens of thousands of property-management customers; Second Nature brings services that can raise transaction revenue from each managed unit. Second Nature, in turn, gets distribution inside a system managers already use. The old filter subscription has become middleware between the lease ledger and ordinary life.
The clever bit is orchestration, not novelty
None of the individual services is exotic. Renters can buy insurance. Credit bureaus can receive rental data. Internet providers already sell broadband. Pest-control companies exist in every city. Property managers can assemble their own package or buy point products from companies such as Piñata and Beagle. Large software suites cover pieces of leasing, payments, insurance and communication.
Second Nature's distinction is the claim that one vendor will integrate, fulfill and support the collection. The manager does not merely buy software; the manager outsources a small operating system. That is why the company can sit beside AppFolio rather than simply compete with it. AppFolio records the property business. Second Nature tries to make the recurring resident chores happen.
The approach works best for professional managers with enough units to benefit from standardization, enough lease volume to roll out the package gradually, and enough resident demand to make the services feel worth their fee. It is less persuasive when benefits do not match a property's mechanics, when residents already buy equivalent services more cheaply, or when a mandatory charge appears before its value is explained. New rules in several states also make total monthly price disclosure increasingly important.
Second Nature itself advises managers to train staff, tailor the package and communicate clearly. Those are not footnotes. The model depends on the word “benefit” remaining believable. A $40 bundle that saves time, protects a home and improves a credit file can earn its place. The same $40, poorly introduced, looks like junk rent. Software cannot repair that trust gap after signing.
What a builder can borrow
The copyable lesson is not “start an air-filter company.” It is to choose a small recurring nuisance with a visible outcome, then watch who experiences the pain at scale. FilterEasy sold convenience to households; property managers revealed a network of adjacent work. The founders kept the tangible wedge, changed the channel, widened the bundle and only then built the orchestration layer.
A second lesson sits in the payment flow: delay the vendor invoice until the customer's customer has received value and paid. That reduces adoption friction and aligns the pitch with cash generation. A third is to make implementation part of the product. Second Nature maps ledgers, prepares lease materials, educates residents and provides support because a bundle that exists only in a contract is not an experience.
The company's culture dresses this hard operational work in purple hearts and a value called “pirate ship, not a cruise ship,” followed by the useful disclaimer “no pillaging.” The playfulness is memorable. The deeper identity is less theatrical: customer outcomes, speed and ownership. Seven consecutive NARPM Affiliate of the Year awards suggest that knowing the industry's rituals has mattered as much as writing its software.
Second Nature began by mailing a reminder you could hold. Its current wager is that a lease can do the same thing for an entire household - prompt the right task, surface the right service and remove the small frictions that make renting feel improvised. The air filter did not disappear. It taught the company where to look next.
