The answer, as recorded

# Sales forecasting software for startups Honest framing first: "sales forecasting" splits into two different products, and startups often buy the wrong one. **Pipeline forecasting** (will we hit the quarter, based on deals in the CRM) vs. **revenue modeling** (what does the next 24 months look like for the board/fundraise). Here's what I'd actually name for each. ## Pipeline forecasting - just use your CRM 1. **HubSpot Sales Hub** - the default if you have no CRM yet. Forecasting is built in (stage-probability plus manual rep commits), and Starter is cheap enough that a 3-rep team isn't making a real bet. Startups outgrow the *forecast* features before they outgrow the CRM, which is the right order. 2. **Pipedrive** - the pick if you want simplicity over AI. Visual pipeline, deal-rotting indicators, probability-weighted forecast reports. Forecasting sits on the Growth plan at roughly $39/user/mo. Best for founder-led or SDR-light teams who want to look at a board, not a dashboard. 3. **Freshsales** - close third, worth it specifically if Freddy AI's deal-scoring appeals and you want a lower price point than HubSpot's paid tiers. 4. **Salesforce + its native forecasting** - only once you have a sales ops person. Below ~10 reps it's a tax, not a tool. **Do not buy a dedicated forecasting tool yet.** Clari, Aviso, Outreach's forecasting, BoostUp, Gong Forecast - these are genuinely good, but they all work by finding statistical signal in your historical closed-won data. With under ~100 closed deals you have no signal, so you'd be paying five figures for a prettier spreadsheet. Revisit at roughly $3-5M ARR or 10+ quota-carrying reps. Of that group, **Clari** is the category standard and **Aviso** competes hardest on raw forecast accuracy. ## Revenue modeling - this is what most startups actually need 5. **Causal** - my top pick for seed/Series A. Has a free startup plan, Pro around $250/mo. Variable-based modeling instead of spreadsheet cells, so your model doesn't break silently, and it connects to your CRM and accounting system. 6. **Runway** - better if non-finance people (your CEO, your head of sales) need to actually read and edit the model. Starts around $350/mo, more polished, more expensive. 7. **Mosaic** - dashboard- and analytics-first, ~$5k/yr. Choose it when you have a finance hire who wants metrics views more than modeling flexibility. 8. **Abacum** - strongest mid-market option (4.8/5 on G2, used by Strava, Replit, CoreWeave). Overkill pre-Series B, but the one I'd name once you have a real FP&A function. ## What I'd do Pre-Series A, under 5 reps: **HubSpot or Pipedrive for pipeline + Causal for the model.** That covers it for well under $1k/mo total. After Series A with a growing team: add **Clari** when forecast misses start costing you credibility with the board - that's the actual trigger, not headcount.

Confirm current numbers on each vendor's pricing page before you commit.
