Process audit, 2-3 days
Where the bottleneck actually sits: review, specs, tests, or the context your agents never get.
Small senior product team
Software that makes the business case visible.
Appience designs and builds web apps, mobile apps, and product interfaces for businesses that need a focused team, fast decisions, and polished execution.

AI-assisted engineering
AI-assisted engineering, installed in your repo.
Teams now write code with AI faster than they can review it. We install the process where agents do the work and the team keeps quality: specs before prompts, repo context for agents, CI as the safety net, and a way to accept work without reading every line. Not a training course - an implementation in your repo, on your code, with your team.
Context and safety net
Repo context for agents (AGENTS.md, standards, skills for your domain), a CI safety net, and clear acceptance conventions.
From idea to merged PR
Specifications, delegation to agents - including parallel ones running in the background - and a working test loop.
The team, not one developer
Acceptance without reading every line, working through resistance, and measurement (cycle time, review throughput) so the process outlives the engagement.
Proof, last 12 monthsAll delivered in agent mode
- CiviCare - an ecosystem of five applications (operational planner, mobile app, admin panel, pilot portal, tracker) built from zero on Next.js and Supabase, in one spec-to-agent-to-review process.
- Patent Cockpit - modules for an international IP management SaaS shipped in an estimate, spec, agents, PR, review cycle; an agent audit of a 32-item backlog took one evening and showed 26 items were already done.
- Our own App Store apps - SoundMemo, 531 Focus, and DentStock, each run by agents on a few hours of founder time per week.

Why Appience
A compact team for products that cannot feel patched together.
One senior team covers framing, design, and implementation, so nothing is lost in a handoff between agencies. You talk to the people who write the code.
Turn the business problem into a product plan.
We clarify the customer, workflow, scope, and release path before screens multiply.
Design and development stay in the same room.
Interfaces are shaped with implementation realities in mind, which reduces rework.
Ship something polished enough to sell.
From mobile apps to dashboards, the output is structured, maintainable, and ready for feedback.
Selected work
Proof, not thumbnails.
Four projects, four different problems: payment features inside a bank's compliance process, apps in the App Store, and web platforms that organizations run on every day.
Żappka Fintech
Buy Now Pay Later and credit card features built into Żappka, the Żabka retail app used by 8 million people in Poland. Delivered with PKO Bank Polski, in an existing codebase and release process.
- 8Mpeople using the app these features ship inside
- 2financial products delivered: BNPL and a credit card, issued with PKO Bank Polski
Payment flows built in SwiftUI and TCA, with RSA-encrypted payloads, JWT and token rotation underneath, and a bank security review on every release.
531 Focus
A native productivity app for planning deep-work sessions, tracking focused progress, and keeping the interface calm when users need momentum.
CiviCare Suite
A civil protection platform for Polish counties and municipalities: threat tracking, preparedness and resource planning, analytics for crisis management staff, and the public landing page.
Oaza Malucha
A warmer website for a kindergarten brand, shaped around trust, clear program information, and fast parent contact.
