Portfolio Construction: Ownership, Reserves, Pacing

Deal selection gets the glory, but portfolio construction determines whether great picks produce a great fund. Two managers with identical portfolios can post wildly different TVPI depending on ownership, reserves, and pacing decisions made before the first wire. Construction is the part of the job that is fully in your control — treat it that way.

Start from the exit and work backwards

The question that anchors everything: what does a fund-returning outcome look like for us? Divide fund size by your realistic ownership at exit. A $50M fund holding 5% at exit needs a $1B outcome just to return the fund once. That single calculation disciplines every other choice — check size, entry stage, ownership target, and how much dilution you can tolerate before the math breaks.

Assume real dilution. A 10% position at seed commonly lands at half that by exit after three or four subsequent rounds, less if you never follow on. Underwrite to ownership at exit, not ownership at entry.

Ownership targets

Ownership is the lever that converts a great outcome into a great fund. Decide your target — and your floor — per initial check, and hold the line. The discipline cuts both ways:

• Too little ownership and even a monster outcome barely moves the fund. A sliver of a unicorn is a story, not a return.
• Chasing ownership at any price pushes your entry valuations up and quietly degrades the portfolio's loss math.

Small collaborative checks into hot rounds feel like progress and build logos, but a fund of 2% positions has outsourced its returns to luck. If your model says 8 to 12% at entry, a deal offering 3% is a pass regardless of how good it feels.

How many names

The power law argues for enough shots on goal to catch an outlier — most seed portfolios run 25 to 40 initial positions. Concentration below that requires either exceptional access or exceptional conviction, and usually both. Above it, your ownership per position collapses and your ability to actually help founders goes with it. Pick the number your strategy and your team can genuinely serve, then build check size from fund size, reserve ratio, and that count — not the other way around.

Reserves: the hardest allocation decision in venture

Reserves are follow-on capital held for existing portfolio companies, and they are where construction discipline most often dies. The core tension: your best companies will offer you the least allocation, and your struggling companies will offer you all you want. Unmanaged, reserves flow toward weakness.

Principles that hold up:

• Set the ratio in advance. Seed funds typically hold anywhere from a third to half of the fund for follow-ons; some high-volume pre-seed strategies deliberately hold near zero and recycle instead. Any of these can work — drifting between them cannot.
• Reserve into strength, not need. A follow-on is a new underwriting decision at a new price, not a loyalty program. The question is never "do they need it" but "would we make this investment fresh today."
• Model reserves per company, not as a pool. Planning tools like Tactyc exist precisely because spreadsheet reserve models rot. Know, for each company, what the next round likely looks like and what your pro rata costs.

Pacing

Deploy the fund over roughly three years of initial checks. Faster, and you've concentrated the portfolio in a single pricing environment — vintage risk you're not paid for. Slower, and your IRR quietly erodes while your thesis goes stale. Set a quarterly deployment budget and review it like a board reviews burn: variances are fine, unexplained variances are not.

Recycling — reinvesting early exit proceeds during the investment period — is the underused pacing tool. Most LPAs permit recycling a meaningful portion of committed capital, and disciplined recycling turns a management-fee drag into extra invested capital. Know your LPA's limits and plan for them from day one rather than discovering them in year four.

Write the construction memo

Before deploying, write down: fund size, initial check count, entry stage, ownership target and floor, reserve ratio and follow-on rules, pacing budget, and recycling plan. Share it with LPs — it is the most persuasive slide in your deck — and review it annually against actuals. When you deviate, deviate deliberately and document why.

Construction won't pick your winners. It ensures that when you do pick one, the fund actually feels it.
