Intro.
#What a Round's Name Actually Means
A funding round isn't simply 'the moment a company receives a large check' — it's capital raised to validate a specific hypothesis. Seed capital exists to validate the product-market-fit hypothesis; Series A capital exists to validate the scale hypothesis. What matters more than the round's label is what that capital is meant to prove.
| Round | Hypothesis to Validate | Expected Timeline |
|---|
| Pre-Seed | Can this team solve this problem? | 6-12 months |
| Seed | Product-market fit (PMF) | 12-24 months |
| Pre-A | PMF reached + early signs of scalability | 12-18 months |
| Series A | Efficiency at scale (CAC, payback period) | 18-24 months |

#Seed — 'Problem-Solution Fit'
The seed round is capital to find product-market fit. PMF is measured by whether people would genuinely be upset if they could no longer use your product. Usability, return visits, NPS, and qualitative interview signals matter more here than revenue.
- Ship an MVP or beta — one product that actually works
- Get your first dozens to hundreds of users, and accumulate qualitative interviews
- Start tracking return visits, repeat purchases, and retention
- Monetization is optional at this stage — but landing even a single paying user is a powerful signal
TIP
The most common mistake at seed is promising you're about to 'start scaling.' Seed is the PMF-validation stage — not the stage where you buy revenue with marketing spend.
03
#Series A — 'Efficient Scalability'
Series A comes after PMF is validated, and it's about proving you can deploy a large amount of capital to efficiently capture market share. At this stage, the numbers that matter are revenue growth rate, CAC (customer acquisition cost), payback period, and LTV/CAC ratio.
| Metric | Typical Series A Benchmark (For Reference) |
|---|
| MRR (Monthly Recurring Revenue) | ₩100M or more, or a clear growth trajectory |
| MoM growth rate | 10-20% average over the past 6 months |
| CAC payback period | Within 12 months |
| LTV / CAC ratio | 3 or higher |
| Monthly churn | B2B: 1-3% / B2C SaaS: under 5-7% |
주의
These benchmarks are SaaS-specific and vary widely by industry and business model. Marketplaces, D2C, and deep tech each run on their own metric frameworks. Start by defining what the Series A bar actually looks like in your industry.

#The Risk of Raising the Wrong Round
Attempt a Series A without PMF, and you'll either get rejected outright or land a lowball valuation that blocks your next round. Conversely, if PMF is clearly there but you settle for seed-level pricing, you take on unnecessary dilution.
| Situation | Risk |
|---|
| Attempting Series A without validated PMF | Accumulated rejections, damaged market reputation, difficulty falling back to a seed-style raise |
| PMF validated but settling for seed pricing | Excessive dilution, weaker negotiating leverage at Series A |
| MRR under ₩100M but labeled a Series 'A' | Later investors relabel it a seed-plus round, discounting the valuation |
| Raising 18 months of runway while promising to scale | Scaling costs exceed the raise, creating pressure to fundraise again |
A round's label isn't something the company gets to decide — it's determined after the fact by the risk profile the investor is actually underwriting. You need to objectively assess which risk profile your company fits.

#Bridge and Extension Rounds — What Pre-A Really Means
More companies are raising a 'pre-A' or 'bridge' round between seed and Series A. This happens when seed capital has run out but the company still falls short of the Series A bar — existing seed investors put in additional capital, or a new investor joins, to bridge the gap.
- Bridge — mostly funded by existing investors, buying 6-12 more months of runway to reach Series A
- Pre-A — a new investor joins, the round is larger than seed, and it's the step immediately before Series A
- Extension — additional capital raised at the same seed price, buying time to prepare for the next round
TIP
A pre-A round aims for a valuation bump, but it can create ambiguity later about whether the next round is really 'A' or effectively 'B.' It's worth agreeing on how the labeling will be redefined before you head into that next negotiation.
Summary.
#Self-Check: Are You Ready for the Next Round
- Can you state, in one sentence, the hypothesis your current stage is meant to validate? (PMF or scale?)
- Can you name three quantitative metrics that back up that hypothesis, right now, off the top of your head?
- Have you defined, in one sentence, what your next round of capital is meant to prove?
- Have you researched at least five comparable valuations from similar-stage deals in your industry?
- Do you have at least 12 months of runway remaining? (This is what preserves your negotiating leverage.)
- If you have existing investors, have you confirmed their appetite to follow on in the next round?
- Do you have a fallback plan to pivot to a pre-A or bridge round if Series A doesn't come together?
