Series A Timeline: 12 Months Out, 6 Months Out, 3 Months Out
The Series A process is the output of work done long before the first partner meeting. Here is the 12-month preparation sequence — what to build, when, and why.
Series A rounds look like four-month processes — soft commitments in Month 1, first term sheet in Month 3, closing in Month 4. In reality, the Series A outcome is shaped by the work done in the 12 months before the first partner meeting. Founders who arrive at the first meeting with an incomplete asset base, unstructured metrics, and unclean governance spend the process rebuilding on the fly. Founders who arrive ready walk through a diligence process that holds together.
Key Takeaway: The Series A outcome is determined in the 12 months before the process starts. The process itself is where the work is verified, not where it is done.
12 months out — foundations
At T-12 months, you are running the business. You are also, whether you acknowledge it or not, building the evidence base the Series A partner will read. Four streams of work matter.
T-12 months: Foundations
Cohort data capture, metric construction, IP hygiene, board and governance cleanup.
T-6 months: Asset register
Build the intangible asset register against the Opagio 12. Strengths + gaps surface. Narrative falls out of it.
T-3 months: Data room + target list
Register becomes the 23-tab data room. Target investor list of 20–30 funds; warm-intro architecture in place.
Months 1–4 of process: Performing
Partner meetings, parallel diligence, term sheets, negotiation, closing. The work is verification — not construction.
Cohort data
Cohort analysis requires cohorts. A business that starts capturing cohort data at T-6 months has six months of data by the time the first meeting happens. A business that started at T-12 months has twelve. The difference is visible in the diligence.
Metric construction
Get the unit economics denominators right a year before you pitch. Decide what counts as CAC, what lifetime assumption underpins LTV, what cohort boundary you use. Changes to the methodology mid-process create diligence red flags.
IP hygiene
Audit IP assignments. Every founder, employee, and contractor who has touched the product must have a signed assignment. Missing assignments from a contractor who left 18 months ago are the single most common Series A legal flag — and they are the hardest to fix quickly.
Board and governance
Clean up the cap table, formalise any unformalised equity promises, ensure board minutes are written and current. Twelve months out, these tasks are administrative. Two months out, they become urgent.
6 months out — the asset register
At T-6 months, build the intangible asset register. Not the data room yet — the register that becomes the data room. The register is the structured view of what you have built, mapped against the Opagio 12, with evidence and confidence levels for each driver.
This is the single highest-leverage work at this phase. A register built at T-6 months informs every subsequent decision. It surfaces which intangible dimensions are genuinely strong and which need focused work. It tells you where to invest the next six months of operator time. It becomes the deck and the data room.
Strengths and gaps
The register exposes where you stand on each of the 12 drivers. Where you are strong, double down — those are your Series A pitch. Where you are weak, decide whether the weakness is fixable in the six months before the round or whether it is a genuine limitation to acknowledge.
Narrative drafting
With the register in hand, the pitch narrative writes itself. The deck, the website, the outbound messaging — all of it downstream of the register. Founders who write the narrative first end up with a story the evidence cannot support. Founders who build the register first end up with a story that the evidence reinforces.
Example: The Round Readiness Diagnostic is the 8-minute starting point for the register. The full register — with evidence, cohort-level detail, and confidence scoring — is built over subsequent weeks on Starter and Growth tiers.
3 months out — the data room
At T-3 months, the register becomes the data room. The register output from the diagnostic maps one-for-one onto the 23-tab institutional Series A structure, so this is construction, not discovery. Three weeks of focused work with the CFO, legal counsel, and one operator per domain produces the institutional-grade data room.
The data room is also where the last-minute legal cleanup happens. Unsigned IP assignments get signed. Cap table anomalies get cleaned. Reserved matters on any prior round's terms get reviewed and cross-checked.
The target investor list
Parallel to the data room build, the target investor list. Twenty to thirty funds that fit: sector, stage, cheque size, portfolio fit. Research each for current thesis, recent investments, and — critically — current deployment pace. A fund that closed its vintage six months ago is a different conversation than a fund with fresh capital.
Warm intros
The best intros come from founders in the portfolio, not from the fund's official channels. Start building those connections at T-6 months; convert to active intros at T-3 months.
Month 1 of the process — partner meetings
First partner meetings happen over a two-to-four-week window. The deck is done. The data room is live. The cohort data is complete. The asset register is the narrative backbone. You are now performing, not building.
Partners who are interested will request the data room within days of the first meeting. Partners who are not interested will go quiet — that is its own signal. Track who requests the data room and who does not. A partner who does not request the data room within a week of a positive-seeming meeting is almost certainly passing.
Month 2 — diligence
Diligence runs in parallel across interested funds. The work intensifies because multiple diligence teams are asking the same questions simultaneously. Founders who pre-built the data room coast through this phase. Founders who are still building it scramble.
The three diligence phases in order: commercial diligence (customer references, market sizing, competitive analysis), financial and legal diligence (the full 23 tabs get inspected), and technical diligence (architecture review, security posture, key-person risk).
Month 3 — term sheets and negotiation
Term sheets typically arrive in Week 9-10 from the funds that make it through diligence. The negotiation phase runs from receipt of the first term sheet through signing.
Key negotiation points: valuation, board structure, reserved matters, option pool sizing, anti-dilution provisions. The board composition guide covers the board-level points in detail. The other dimensions are beyond the scope of this cluster.
Month 4 — closing
Legal documentation, closing conditions, final diligence items, funds transfer. Four to six weeks from signed term sheet to closed round is typical. Founders who kept the data room clean through the process close faster.
The underlying pattern
Series A is a test of preparation, not performance. The work that matters happened in the 12 months before the first meeting. The process is the verification phase, not the construction phase. Founders who understand that arrive ready and walk through cleanly. Founders who do not arrive ready and rebuild in public.

The Bottom Line
Series A is a twelve-month preparation followed by a four-month verification. Founders who start the register work at T-12 months walk through the process; founders who start at T-3 months rebuild in front of the diligence team. Eight minutes with the diagnostic is the smallest possible version of the first step.
