What's new in Spendmix

v1.4.0New Feature

Budget Scenario Planner

  • Create what-if scenarios by dragging budget sliders across your channels. No limits on how many you save.
  • Put up to 4 scenarios next to each other — see projected ROI, revenue lift, and where returns start dropping off.
  • Export comparisons as branded PDFs when you need to walk someone through the numbers.
v1.3.2Improvement

TikTok Ads Connector Improvements

  • Spark Ads and TopView placements now show up in your TikTok spend breakdowns.
  • TikTok data syncs went from 6 hours down to under 45 minutes.
  • Fixed a bug where OAuth tokens would randomly fail to refresh on accounts with MFA turned on.
v1.3.0New Feature

Weekly Model Refresh for Growth Plans

  • If you're on Growth or Pro, your model now recalibrates automatically every week using the last 7 days of data.
  • A freshness indicator on the dashboard tells you when the model was last updated and how confident it is.
v1.2.0New Feature

Plain-Language Insights Engine

  • After each model run, you get a written summary that explains what's driving results, where channels are saturating, and what to do about it.
  • You can export these summaries and share them over email or Slack — they're written for people who don't live in spreadsheets.
  • Built on LLM interpretation of Meridian's posterior distributions. You don't need a stats background to read them.
v1.1.0New Feature

LinkedIn Ads Connector

  • Hook up your LinkedIn Ads account and pull campaign spend, impressions, and conversions straight into your model.
  • Sponsored Content, Message Ads, and Lead Gen Forms each get treated as their own channel.
v1.0.2Fix

Dashboard Performance & Stability

  • Fixed a bug where the channel contribution chart broke on models with more than 8 channels.
  • Dashboard loads about 40% faster now — we lazy-load the heavy chart components.
v1.0.1Improvement

Onboarding Flow Enhancements

  • Added tooltips to the data source setup so it's clearer what each step needs.
  • There's now a progress bar that shows roughly how long model training will take.
  • Better error messages when CSV uploads fail validation — you'll actually know what went wrong.

  • Ships with Google Ads, Meta Ads, and GA4 connectors — connect with one OAuth click.
