Investor Pipeline Calculator
Key Takeaways
Fundraising success is a math problem before it's a pitch problem: your target raise equals the number of investors you meet, multiplied by your conversion ratio, multiplied by your average check size.
Most founders undersize their outreach list because they anchor on their target raise instead of their expected conversion rate.
Conversion ratio should be measured from qualified top-of-funnel to signed check, and first meeting to signed check — the two numbers are very different:
Full Funnel (Intro → Investment): Across an entire outreach campaign, most startups close only about 1–3% of initial conversations into an actual investment. Pre-seed rounds tend to run lower, around 0.5–1.5%; seed rounds tend to run higher, around 2–4%. This number reflects everything — cold outreach, warm intros, and dead ends included.
Meeting → Investment: Once you're in a qualified first meeting, conversion improves substantially. Pre-seed founders typically close 5–15% of first meetings into a signed check; seed founders typically close 5–10%. This is the number the calculator uses, since it reflects the pipeline of meetings you're actually working, not your entire cold-outreach funnel.
Adjusting your check size assumption (angel vs. lead investor) changes your required pipeline size dramatically (this calculator lets you test both).
The Law of the Pipeline Calculator
Fundraising is a conversion problem before it's a pitch problem. Before you send a single cold email, you can calculate exactly how many investors you need to meet to close your round — and Allied's Pipeline Calculator does the math for you.
Why This Matters
Most founders build their fundraising strategy backwards. They start with a target number, build a pitch deck, and start reaching out without ever calculating how large their outreach pipeline actually needs to be.
The math is simple, but it's rarely made explicit:
Target Raise = Number of Investors Met × Conversion Ratio × Average Check Size
Rearranged, that tells you exactly how many prospective investors you need in your pipeline:
Investors to Meet = Target Raise ÷ (Conversion Ratio × Average Check Size)
A founder raising $1.5M at a 10% conversion ratio and a $50,000 average check size needs to meet roughly 30 qualified investors (not 30 cold emails), 30 actual first meetings. Skip this calculation, and it's easy to under-build your pipeline and stall out halfway through a round.
How the Calculator Works
Enter three numbers:
Target Raise: the total amount you're looking to close for this round.
Conversion Ratio: the percentage of first meetings that convert into a signed check. (Not sure what to use? See the benchmarks below.)
Average Check Size: your expected check size, from angel-sized checks up to lead-investor checks.
The calculator instantly shows how many investors you need to meet, visualizes your pipeline from first meeting through capital raised, and compares Conservative, Base, and Optimistic conversion scenarios side by side, so you can stress-test your outreach plan before you start.
Conversion Ratio Benchmarks
Your conversion ratio is the single input most founders get wrong, mostly because they conflate two very different numbers:
Full Funnel (Intro → Investment): Across an entire outreach campaign, most startups close only about 1–3% of initial conversations into an actual investment. Pre-seed rounds tend to run lower, around 0.5–1.5%; seed rounds tend to run higher, around 2–4%. This number reflects everything — cold outreach, warm intros, and dead ends included.
Meeting → Investment: Once you're in a qualified first meeting, conversion improves substantially. Pre-seed founders typically close 5–15% of first meetings into a signed check; seed founders typically close 5–10%. This is the number the calculator uses, since it reflects the pipeline of meetings you're actually working, not your entire cold-outreach funnel.
Use the Meeting → Investment range to set your conversion ratio, then build your outreach list well above the base-case number. Not every conversation you have will convert into a qualified first meeting.
Try Different Scenarios
Fundraising rarely goes exactly as planned. Use the calculator's sliders to model:
A smaller angel check vs. a larger lead investor check, and see how dramatically your required pipeline size shrinks or grows.
A conservative conversion ratio if your traction or network is still developing, vs. an optimistic ratio if you have strong warm introductions.
Different target raise amounts as your round size evolves during the process.
Building your pipeline is step one. If you're raising a pre-seed or seed round and want feedback on your investor list, your pitch, or your round structure, Allied Venture Partners works with founders across Canada and the U.S. — pitch us or explore our Founder Resources.
FAQ
What is "the law of the pipeline" in fundraising?
It's the mathematical relationship between your target raise, the number of investors you meet, your conversion ratio, and your average check size. Target raise equals investors met multiplied by conversion ratio multiplied by average check size — so you can solve for exactly how many investors you need in your pipeline.
How do I calculate how many investors I need to meet?
Divide your target raise by the product of your conversion ratio and your average check size: Investors to Meet = Target Raise ÷ (Conversion Ratio × Average Check Size). The Pipeline Calculator does this instantly and lets you adjust each variable.
What's a good conversion ratio for a pre-seed round?
Measured from qualified first meeting to signed check, pre-seed founders typically convert 5–15% of meetings. Measured from initial outreach across the full funnel, pre-seed conversion is much lower, typically 0.5–1.5%.
What's a good conversion ratio for a seed round?
From first meeting to signed check, seed founders typically convert 5–10%. Across the full outreach funnel, seed conversion typically runs 2–4%.
Should I use my full outreach conversion rate or my meeting conversion rate in this calculator?
Try testing both your entire cold-outreach funnel and your meeting-to-close conversion rate (the percentage of qualified first meetings that turn into a signed check). This calculator is built to size both your entire cold-outreach funnel and your active pipeline of meetings.
How does average check size affect my required pipeline size?
Check size and pipeline size are inversely related: doubling your average check size roughly halves the number of investors you need to meet, assuming the conversion ratio stays constant. This is why many founders try to secure at least one lead investor early — a single large check can dramatically shrink the remaining pipeline needed.
Does this calculator account for lead investors writing larger checks?
Yes. The average check size input ranges from $5,000 up to $2,000,000, so you can model everything from a small angel check to a lead investor's check size.
How many investors should I add to my outreach list beyond the calculator's number?
Since not every outreach conversation converts into a qualified first meeting, most founders build their outreach list at 2–4x the calculator's "investors to meet" figure to account for meetings that don't materialize or don't reach a decision.
Is this calculator specific to pre-seed and seed rounds?
The underlying math applies to any round size or stage. The benchmark conversion ratios shown are specific to pre-seed and seed, since those are the stages Allied focuses on, but you can substitute your own conversion assumptions for Series A or later rounds.
