You are deciding whether to start a Series A process now, keep executing, or bridge. Seed bet on a team and a thesis. Series A underwrites a machine: repeatable, capital-efficient growth that more capital can accelerate (Burkland, 2026). Calendar anniversaries do not underwrite that machine. Carta’s median seed-to-primary-A wait sat around 20 months in Q2 2025 (616 days) and 1.9 years in Q4 2025. Treat those as market medians, not your go/no-go. Not legal, tax, or investment advice.
What you are deciding
| Decision | Do this | Skip this |
|---|---|---|
| Start the Series A process | Repeatable growth + retention + efficiency you can defend; 9–12+ months runway at first meetings (Burkland) | Opening because the seed round turned 18 months old |
| Keep executing | Flat or lumpy recent months; founder-only sales with no transfer evidence; metric definitions still disagree across deck and board pack | Pretending a vision deck substitutes for cohort evidence |
| Bridge or extend cash | Under ~6 months runway into outreach (Burkland); you need months to hit a clear milestone before partner pitches | Starting a full process while desperate on cash |
| Prep in parallel | Data room, metric glossary, and hiring plan built while you execute (diligence checklist) | Waiting for a term sheet to assemble the room |
fn-content has no verified atom yet for Series A readiness ARR bands, NRR at A, runway at process start, or median seed-to-A months. fn-content tracks it as benchmark request: Series A readiness ARR / NRR / runway at process start. Until then, use the named public sources below. Do not invent a “typical” ARR for your sector.
Score readiness before you open the calendar
| Lens | “Ready enough to open” (cited context) | Where to go deep |
|---|---|---|
| ARR / growth band | Burkland: many SaaS Series A conversations cluster around roughly $1M–$3M ARR; cadence matters ($2M at 10–15% MoM ≠ $2M at 3% MoM). AI in the 2026 cycle: roughly $3M–$5M reads strong and growth bars run steeper. Bessemer fundability: 75%+ / 100%+ / 125%+ YoY as Good / Better / Best. | Your board pack and forecast; sector yardstick in Burkland |
| NRR / retention | Burkland: NRR above 100% is a strong Series A signal. Bessemer: 100% / 110% / 120+%. Show GRR and NRR as separate lines so growth does not hide churn. | NRR vs GRR |
| Capital efficiency | Burkland: burn multiple under ~2x generally viewed as efficient for early SaaS; CAC payback under ~12–18 months viewed favorably with SMB vs enterprise variation. Sacks/Craft bands on the sibling page. Bessemer Efficiency Score is the inverse framing (net new ARR ÷ net burn). | Burn multiple vs Rule of 40 |
| Runway at process start | Burkland: under 6 months signals desperation; 9–12+ months is stronger. Bessemer “time to cash out”: 12 / 18 / 24+ months Good / Better / Best. Model months the raise itself consumes (Burkland: plan 3–6 months to close). | Runway calculator |
| GTM repeatability | Burkland: early evidence that non-founder sellers can close; funnel history and ramp data. Series A capital often buys distribution. | Series A leadership hiring sequence |
| Concentration / hygiene | Burkland red flags: extreme revenue concentration with no plan; inconsistent metric definitions; messy cap table or missing IP. Fix before outreach. | Diligence checklist |
Treat each band as cited context for your model and cycle, not a pass/fail gate you invent for the deck.
Readiness sequence
Score, then sequence
- Lock one metric glossary. ARR, GRR, NRR, CAC, payback, burn, and runway mean the same thing in the board pack, model, and deck. Burkland calls inconsistent definitions a deal risk on their own.
- Write the six-lens score. Fill the table above with your last 3–6 months. Mark which lenses are evidence and which are still a bet. Operator judgment: if two or more core lenses are still bets, keep executing (FounderNexus session).
- Check cash at process start. Compute runway with the hiring plan you will run. If you are under Burkland’s 6-month warning, extend cash or delay outreach. Target 9–12+ months before first serious partner meetings.
- Prove transfer beyond founder-led sales. Show early seller ramps, a sequenced hiring plan tied to use of funds, or an honest gap with a date. Capital that only buys more founder hours is a weak A story.
- Stage the room, then open. Partner-pitch materials and legal spine ready before outreach (diligence checklist). Burkland: preparation should start 6+ months before the raise, not when the first term sheet conversation begins.
When not to raise yet
| Signal (cited) | Why it blocks a clean process | Better move |
|---|---|---|
| Under 6 months runway into outreach (Burkland) | Desperation signal; weak negotiating position; rushed diligence | Bridge, cut burn, or delay until 9–12+ months |
| Flat or lumpy growth at a given ARR (Burkland growth-cadence frame) | Investors underwrite a machine, not a snapshot | Keep executing until cadence is visible in cohorts |
| NRR under the “strong” bar for your story, or GRR hidden under blended growth (Burkland / Bessemer) | Retention problems compound when you pour Series A into GTM | Fix product and success before buying distribution |
| Founder-only sales with no transfer evidence (Burkland) | Series A capital often funds distribution scale | Hire or prove an early non-founder closer first |
| Metric definitions that change across deck, model, and room (Burkland) | Associates rebuild the numbers; inconsistency looks like spin | One glossary; one source dashboard |
| Extreme concentration with no diversification plan (Burkland) | One logo can sink the underwriting | Name it; show the next-20 customer plan |
Carta’s stretching seed-to-A medians are market context. A longer wait than 18–24 months is common in recent years. It is not, by itself, a reason to force a process.
Calendar vs machine
| Frame | What it optimizes for | Failure mode |
|---|---|---|
| Calendar (“we raise on an 18-month clock”) | Habit and board expectation | You open cold with a thin machine and short runway |
| Machine (Burkland) | Evidence investors can accelerate with capital | You wait for a perfect number that does not arrive |
| Fundability (Bessemer SotC 2023) | Control of burn, retention, growth, and cash-out date | You time the public market and miss available capital |
Use Carta for planning runway between primary rounds. Use Burkland and Bessemer for the go/no-go on whether the story is underwritable now.
Mistakes that waste a raise
Opening because the seed anniversary hit. Carta medians moved. Your readiness did not follow on its own.
Starting with under 6 months of cash. Burkland flags this as desperation. The process itself can take 3–6 months.
Treating ARR as the only slide. Burkland and Bessemer both weight retention and efficiency next to scale.
Skipping GTM transfer. If only founders close, Series A capital buys more of the same bottleneck.
Building a second “investor forecast.” Underscore’s hygiene bar (on the diligence spoke) is the same here: share the forecast you run the company on.
