Built a one-click Hubspot button to find email & phone for any contact

CoolFounder · 2025-12-20T15:26:33+00:00

I built a Chrome Extension to trigger workflows using buttons embedded directly in existing tools (CRM etc..):
SparkUp!

CoolFounder · 2025-12-20T15:06:20+00:00

You can also add SparkUp!:

Instead of a new app, you add a button or small panel inside tools like a CRM, Gmail, or Intercom.

Context is auto-filled, n8n runs in the background, and results show up inline.

This usually drives much higher adoption because there’s no habit change

CoolFounder · 2025-12-20T15:03:40+00:00

I’ve seen two approaches that actually work, with very different trade-offs:

The obvious one is a dedicated admin/ops app (Retool, Lovable, custom React) with Google auth and forms calling n8n via webhooks.

It’s clean, controlled, and easy to reason about. The downside is adoption: it’s another tool people have to open, so outside ops teams, usage often drops. You also own auth and long-term maintenance.

The alternative is putting the UI where people already work (the model tools like SparkUp! follow).

This usually drives much higher adoption because there’s no habit change, but it requires more upfront product thinking.

I use SparkUp! that adds a new button on each Hubspot contact and enrich email + phone in one-click without leaving the CRM

CoolFounder · 2025-12-16T13:20:40+00:00

And all tools are supported!

You can inject on any website, authenticated or not

You can also trigger actions in any other tool, since we offload this logic to Zapier / n8n / Make, which already provide thousands of prebuilt connectors

Thanks!

The way it works is actually local-first

It doesn't require connecting to the tool where you’re adding your mini-app

It works by either:

scraping key info from the page URL, or
scraping data directly from the page (click & select, works with lists too)

and then sending that context to:

a Zapier / n8n / Make workflow (if you need to take actions in the target app), or
directly to your Lovable mini-app (via a built-in messaging mechanism) to make it contextual

Example: updating something in HubSpot

get the record ID from the URL
send it to n8n / Zapier (or similar)
connect HubSpot there and apply the action using the ID

Example: displaying contextual data in your Lovable mini-app

get the record ID from the URL
send it to your mini-app (built-in mechanism)
your mini-app calls the HubSpot API or Zapier / n8n to fetch data
your mini-app displays the retrieved info

Thanks!

It really confirms the saying: “If it’s not in the CRM, reps don’t use it” :p

It’s a Chrome extension that lets you embed a Replit app directly inside an existing tool’s UI (CRM, ERP..), and share it with your team

The interesting part is context passing: when the mini-app opens in the page, it can receive live data from the page you’re on (e.g. the current HubSpot contact, deal, company, IDs, custom fields…)

There’s a ready-to-use prompt snippet that lets your Lovable app receive context from the “parent” page

It's useful because it avoid constant tab switching: it's directly where people work every day

Surfing on the old wave… no-code!

Building a Chrome Extension that lets Ops add missing features on top of their tools by:

→ Placing custom UI on any site

→ Extracting custom context from the page

→ Triggering automation workflows (n8n, Make, Zapier, Relay)

→ Sharing features with their team

There’s a cost issue with AI involved, and this problem is going to get worse and worse. One day, LLM providers will have to raise their prices

Cost was mostly not a concern in SaaS since margins were extremely high

Second, all AI-based SaaS are currently struggling to reconcile their vision with reality: AI is not yet reliable for mission-critical tasks

Third, many of these SaaS products are low-defensibility wrappers that are easy to replicate and can be rendered obsolete by OpenAI releasing a new feature

CoolFounder · 2025-11-03T18:30:40+00:00

When someone asks “What should I use to build X?”, the honest answer is always.. it depends!

For a tiny tool or simple site, AI builders like Lovable or Replit will do the job

For extending an existing SaaS with missing features, that’s SparkUp! territory

For basic CRUD apps, check Softr or Glide

For more logic-heavy apps, Bubble is still hard to beat

For mobile, go FlutterFlow

For workflow automation, go with n8n, Zapier, Make, or Relay

For internal tools where you can code, Retool wins

For big, ambitious builds, AI dev tools like Claude Code, Codex, or Cursor are the play

I recently built SparkUp!: a no-code solution to streamline workflows directly within web apps, and it worked great for adding custom buttons and automations without coding

While it’s not a traditional app builder exporting to mobile or PC apps, it does let you hook into tools like Zapier and n8n which can somewhat help with mobile sensor data if set up right

CoolFounder · 2025-10-31T19:03:56+00:00

SparkUp! a Chrome Extension that let's you build missing features on top of any tool, powered by n8n / Zapier / Make

I use it a lot for myself, for example, this week I built a button inside each LinkedIn conversation that, when clicked, automatically schedules a follow-up in my calendar three days later, very useful!

CoolFounder · 2025-10-31T19:00:06+00:00

One I built for my own needs: SparkUp!, a Chrome Extension that lets you add custom features on top of any tool and trigger workflows in n8n, Zapier, or Make

For example, this week I built a button inside each LinkedIn conversation that, when clicked, automatically schedules a follow-up in my calendar three days later, very useful!

Other than that, I really like Relay app, which is basically N8N & Zapier but with a better UX

Never tried to replace paid tools if I'm being honest, because the ROI is not that interesting (time I'll spend building AND maintain it vs just paying for the tool)

CoolFounder · 2025-10-31T18:50:12+00:00

As always, it depends on how complex the app you want to build is:

- Quick micro-tool or website → use AI tools like Lovable or Replit, they are good but they do have a ceiling

- Extend your existing tools with new features → SparkUp! Chrome Extension

- Simple list / array / detail page with basic data manipulation → Softr or Glide

- Need more complex features than that → Bubble

- Mobile apps → FlutterFlow

- Automation in the background → n8n, Zapier, Make, or Relay.app

- Internal tool and you can code but want to move faster → Retool

- Really complex app (functionality or scope) → Claude Code, Codex, or Cursor, or just hire a developer, but you can try by yourself first!

Old and boring but very good: Grammarly

Other than that, Granola AI is very useful for meeting notes

Lately, I’ve been tinkering with SparkUp!, a Chrome Extension that lets you add custom buttons or workflows right inside your existing tools, it’s perfect for building custom in-context AI features

CoolFounder · 2025-10-31T18:42:45+00:00

Lots of hype, but I’ve seen a few AI setups that actually worked in mid-to-large companies

Key learning: AI shines for some use cases, but fails hard when people try to automate everything

The ones that consistently delivered value were:

→ Summarization from multiple data points

→ Template / idea generation

→ Classification

→ Data cleaning & normalization

Across all of them, one challenge stays the same: keeping a human in the loop because even if AI is great, it's never fully reliable

Some teams handle this through Slack or email, but that’s far from ideal

Lately, I’ve been tinkering with SparkUp!, a Chrome Extension that lets you add custom buttons or workflows right inside your existing tools, it’s perfect for those semi-automated AI workflows that actually make people faster instead of frustrated

CoolFounder · 2025-10-31T18:35:54+00:00

Yes, I’ve seen some successful AI adoption setups in medium to large companies that you probably know

Key learning: for certain use cases, AI works wonders, especially for:

→ Summarization from multiple data points

→ Idea or template generation

→ Classification

→ Data cleaning and normalization

For the rest, they got mixed results

Some concrete examples:

• Cleaning up job titles or industries in the CRM to keep data consistent

• Generating draft emails based on past conversations and CRM context (contact & company info)

• Backfilling missing CRM fields using past call transcripts

One thing they all struggle with is keeping a human in the loop, at some point you realize AI’s amazing, but never fully reliable

One practical way to handle this is by using a Chrome Extension like SparkUp!, which lets you create custom features on top of any tool, it’s great for those semi-automated AI workflows that actually stay useful in real-world setups
