AI-native
delivery
AI in the loop from spec to ship: generation, review, refactors, tests, docs. Faster than agencies built before the AI era, with the review discipline a working product needs.
Build the listings, the agent CRM, and the integrations brokers actually use.
Listings + search, agent CRMs, lead capture, e-signature, mortgage and MLS integrations. The software the brokerage runs on, built to scale beyond the franchise template. One subscription, pause any time, no notice period.
Subscription, fixed build, or white-label, depending on the work.
See all ways to workThe patterns we ship for PropTech teams
PropTech software lives between four constituencies (agents, buyers, sellers, brokerage ops) and every transaction touches all four. Here are the patterns we've shipped before.
01
Listings + faceted search
Map + list views, saved searches, alerts. Elasticsearch or Typesense underneath, debounced filters, indexable detail pages for SEO.
02
Agent CRM + lead routing
Round-robin or scoring-based routing, activity timelines, SMS + email follow-up, calendar integrations. The CRM agents actually log into.
03
Document e-signature flows
DocuSign, Dropbox Sign, or custom. Field positioning, signing order, audit trail, status webhooks. The closing without the printer.
04
MLS + IDX integrations
RETS, RESO Web API, MLS-specific syndication feeds. Normalised into one schema, refreshed continuously, search-ready.
05
Mortgage tech integrations
Lender APIs, rate engines, pre-approval flows, AUS submission. The mortgage half of the transaction wired in.
06
Operator console
Listings, agents, transactions, commissions, payouts. The internal software the brokerage owner actually runs the business from.

Four featured projects Stacklane delivered end to end. Engineering, design, and brand on one cadence, with no internal hires required.

Real
software
Architected, reviewed, tested, owned. Software you can keep, maintain, and hand over. Not demoware, not prototype code that ships, not unreviewed AI output sent to your customers.
Visible
progress
Progress you can see as it happens, not at quarter-end. Working software, not a slide deck. Pause anytime with 7-day notice.
End-to-end
ownership
Accountable for what ships, not what gets coded. Discovery, design, build, deploy, maintain. One team that owns the outcome.
Frequently Asked Questions
01
How fast will I receive results?
We usually start the same day after onboarding. You'll see progress daily and weekly, with features and improvements delivered continuously based on your backlog and priorities.
02
Who will work on my product?
Senior software developers, 8+ years in production, with AI in the loop end-to-end. We use the AI tooling, we own the architecture, and we sign the review on every PR. Stacklane takes full responsibility for delivery.
03
Is there a limit to how many requests I can make?
No, you can submit as many requests as you want.
04
How do you handle larger requests or features?
Large features are broken down into smaller milestones and delivered step by step. You always see progress and can adjust priorities as we go.
05
Can agencies use this as a white-label solution?
Yes. Agencies can work with Stacklane as a technical partner and offer our software services under their own brand if desired.
06
What if I only have a single request or small project?
We also offer one-off projects with fixed pricing. If you don't need ongoing development, a one-off project may be a better fit.
07
What if I don't like the result?
We work closely with you and iterate based on feedback. Our goal is to build software that fits your needs, not just deliver code.
08
Are there any requests you don't support?
We focus on software development and product design. We are not a good fit for simple marketing websites, very small design-only tasks or non-software services. If you're unsure, we'll help you determine fit during the discovery call.
09
How do we communicate and request work?
You submit requests through a shared backlog or project board. We communicate through tools like Slack, email, and regular check-ins.
10
How does pricing work?
Stacklane works on a flat monthly subscription: predictable pricing, no hidden fees, no long-term contracts. You can scale up, pause, or cancel at any time.
11
Are there any refunds?
We don't refund time already worked. Pause or cancel any time to avoid future charges; both take effect from the next billing cycle.
