TechStackTrack helps growing startups and scaleups stay on top of every SaaS subscription and auto-generates a Security Page that is up to date to help you win bigger deals in Europe.

Vendors, renewals, and costs - before they drift and eat your margins. Connect your tools, get alerted ahead of yearly renewals, and spot what you're overpaying for or no longer using - to maximize output for your team.

When you start selling upmarket, security reviews slow everything down. TechStackTrack solves this automatically: as you add tools to your stack, your subprocessor list and Security Page stay up to date, and are ready to share. Send prospects a branded link instead of a spreadsheet or scattered documents. Proactively answer the compliance questions before they are asked. One platform for the internal work of controlling spend and the external work of building trust. Letโ€™s brag about your tech stack to attract talent, investors, and customers. Embed it to your website as proof you take this seriously. You stop answering the same tech stack or compliance questions over and over. Your champion on the buyer side gets what they need to push the deal through internal review. Deals move faster.

Whether you're a 10-person team getting your first real SaaS stack under control, or a 150-person scaleup closing enterprise contracts with procurement teams, the platform grows with you. Start free (limited offer)

Questions & Answers

As answered by people managing Apache Karaf and TechStackTrack.

What's the story behind your product?

TechStackTrack's answer:

Scaling the team at Lime, I thought I had costs under control - until I didn't. Tracking spend across employees meant endless spreadsheets and receipts, while trying to calculate how costs would scale for our next hires. On top of this we didn't have a proper security documenation which resulted in internal ping pong of sheets, docs, and links. Starting Nom made it worse. Subscriptions, renewals, cash flow forecasting, mapping out subprocessors - it was a constant juggling act. I realized every founder and revenue leader faces this same silent pain. So we built the tool I needed: one place to manage subscriptions, predict costs as you scale, and benchmark alternatives. And keep your subprocessors list up to date and win deals faster with a trusted Security Pages. No spreadsheets. No surprises. Just clarity - internally and externally.

Apache Karaf mentions (1)

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: over 5 years ago
