STACKER AGENCY: BUILD CUSTOM PORTALS FROM YOUR DATA
Hack'celeration is a Stacker agency that builds custom portals and internal tools on top of your existing data. Whether you use Airtable, Google Sheets, or Salesforce, we transform your databases into real applications your team and clients can actually use.
We create client portals with secure authentication, internal tools with role-based permissions, custom dashboards with filtered views, and automated workflows that connect to your entire stack (Make, Zapier, your CRM). Everything branded to your identity.
We work with startups that need to ship a client portal fast, SMEs drowning in spreadsheets that need a proper interface, and scale-ups managing complex operations across multiple data sources.
Our approach: understand your data structure, build a clean interface, deploy fast. No fluff, no over-engineering. Just a system that works and that your team will actually use.
Let's build your growth engine.
Why partner
with a Stacker agency?
Because a Stacker agency can transform your messy spreadsheets and scattered databases into a clean, professional application your team and clients will actually want to use.
You've got data in Airtable, Google Sheets, or Salesforce. It works, but it's ugly. Your clients can't access it. Your team needs to dig through tabs and filters to find what they need. You need a real interface, but custom development costs too much and takes forever.
Custom portals in days, not months → We build client portals, partner dashboards, and internal tools directly from your existing data sources. No migration needed.
Real permissions and security → We configure role-based access, user authentication, and filtered views so each user sees exactly what they should see. Nothing more, nothing less.
Your brand, not Stacker's → We customize layouts, colors, and domains so your portal looks like your product. Your clients won't know it's built on Stacker.
Connected to your stack → We integrate Stacker with your tools (Make, Zapier, Slack, your CRM) via actions and automations so data flows where it needs to go.
Autonomy included → We build a system you can manage yourself. Add users, modify views, update content without calling us every time.
Whether you're starting from scratch or already have a Stacker setup that doesn't quite work, we help you get a portal that actually solves your problem.
Our methodology
for Stacker Agency.
STEP 1: AUDIT YOUR DATA AND NEEDS
We start by understanding what you’re trying to build and mapping your existing data structure.
We analyze your data sources (Airtable bases, Google Sheets, Salesforce objects) to understand relationships, fields, and current organization.
We identify who will use the portal (clients, partners, internal team), what they need to see, and what actions they need to perform.
We define the user roles, permission levels, and filtered views required for each user type.
At the end of this step, you have a clear scope document with wireframes, user flows, and a precise understanding of what we’re building.
STEP 2: ARCHITECTURE AND DATA PREPARATION
We structure your data to work perfectly with Stacker’s interface capabilities.
We optimize your Airtable bases or Google Sheets with proper field types, relationships, and formulas that Stacker can leverage.
We configure your data source connections with the right sync settings and permissions.
We set up the foundational views, layouts, and page structure that will power your portal.
At the end of this step, your data is ready and the skeleton of your application is in place.
STEP 3: PORTAL DEVELOPMENT
We build your custom interface with all the features you need.
We create pages with list views, detail views, forms, and dashboards tailored to each user type.
We configure role-based permissions so clients see their data, partners see theirs, and admins see everything.
We set up actions (record creation, updates, status changes) and connect them to automated workflows.
We apply your branding: custom domain, logo, colors, and layouts that match your identity.
At the end of this step, you have a functional portal ready for testing.
STEP 4: INTEGRATIONS AND AUTOMATIONS
We connect your Stacker portal to your broader ecosystem.
We set up actions that trigger automations in Make or Zapier (notifications, data sync, email sending).
We configure user authentication and SSO if needed for enterprise clients.
We connect to external APIs for data that lives outside your main data source.
At the end of this step, your portal is fully integrated with your existing tools and workflows.
STEP 5: TESTING AND DEPLOYMENT
We validate everything works before going live.
We test each user role to ensure permissions work correctly and views show the right data.
We verify all actions, forms, and automations trigger properly.
We configure your custom domain and SSL certificate.
At the end of this step, your portal is live and accessible to your users.
STEP 6: TRAINING AND HANDOVER
We make sure you’re autonomous with your new system.
We train your team on managing users, modifying views, and making day-to-day changes.
We provide documentation covering your portal architecture, admin tasks, and troubleshooting.
We stay available for questions and offer maintenance packages if you want us to handle evolutions.
At the end of this step, you own a system you understand and can manage independently.
