Every venture I have ever audited has been running at least one practice that used to work, no longer works, and continues to consume time, money, or attention because nobody has noticed it has become obsolete. The practice was once a sound decision, made for sound reasons, against a market reality that has since changed. The decision was never revisited because nobody scheduled the revisit, and the practice persists by inertia rather than by current relevance.
I want to argue in this piece that the discipline most ventures most need is not better strategy, sharper execution, or stronger marketing. It is the boring, structural discipline of periodically auditing the assumptions underneath the venture’s operating practices, on a regular schedule, against a defined set of questions. Without this discipline, ventures accumulate obsolete practices the way old houses accumulate dust, slowly and invisibly, until the cumulative weight is heavy enough to feel and the source is impossible to locate.
The audit takes about an hour per quarter. It is one of the highest-leverage hours a founder can spend. And in my experience, almost no founders run it.
What an assumption is, and why they go obsolete
Every practice in your venture rests on a set of assumptions about how the world works. The assumption may be explicit, as in “we run this campaign on Facebook because that is where our customers are.” More often, the assumption is implicit, baked into a decision made years ago that no one remembers questioning. The hiring profile that was right when the venture was at five people and is no longer right at fifteen. The reporting cadence that fit the original cofounder structure and is now the wrong rhythm for a board that has been added since. The marketing channel that was producing pipeline two years ago and is now producing the appearance of pipeline.
Assumptions go obsolete in three predictable ways.
The first is market shift. The world outside the venture changes in ways that invalidate what was previously true. A platform you depended on changes its algorithm. A regulator changes the rules. A customer behaviour you optimised against shifts. A competitor moves into a position that breaks your previous differentiation. The shift is real, the practice has not adjusted, and the gap between practice and reality is the cost.
The second is internal scale. The venture itself grows in ways that make the original practice unfit. A solo-founder communication style does not scale to a team of twenty. A pricing structure that worked at ten customers does not work at four hundred. A hiring approach that worked when the founder personally interviewed everyone does not work when the founder is interviewing two of every ten. The practice was right for a smaller venture and is wrong for the current one.
The third is customer composition shift. The customers the venture is now serving are not the customers it was originally built for. The early customers, drawn from the founder’s network, have given way to a broader market with different expectations, different decision processes, different willingness to pay. The marketing copy that resonated with the early customers no longer lands with the current ones. The product features that the early customers valued are not what the current ones are buying for. The practice persists, calibrated to a customer profile that has substantially changed.
In each case, the practice was not wrong when it was instituted. It is wrong now, and the wrongness is invisible because the practice has not been examined since the conditions changed.
The five categories an audit covers
The audit I run quarterly examines five categories of practice. Each takes about ten minutes. The total exercise is an hour and produces a list of two to four practices that need updating, retiring, or reinventing.
The first category is marketing channels. For each channel currently in use, I ask: what has the channel produced in the last ninety days, and is the production rate the same, better, or worse than the previous ninety days. A channel whose production has declined for two consecutive quarters is a candidate for either intervention or retirement. The channels that founders carry forward longest, in my observation, are the ones that produced strong results two years ago and have been gently declining since, with no single quarter declining steeply enough to trigger reconsideration. The cumulative decline is the audit’s job to surface.
The second category is pricing and packaging. Have the prices kept up with the value being delivered, the cost of delivery, and the market’s reference points. Founders systematically underprice over time because the discomfort of raising prices is immediate and the cost of not raising them is gradual. The audit asks: what is the gap between what we charge and what equivalent providers in our category now charge, and what would it take to close it. This question, asked once a quarter, prevents the slow erosion of margin that catches founders by surprise after eighteen months.
The third category is hiring profile. The job descriptions in active recruitment, and the profiles of recent hires, audited against the profile the venture now actually needs. Most hiring profiles drift behind the venture’s actual stage by six to twelve months. The audit catches the drift before too many wrong-stage hires are made.
The fourth category is reporting and meeting cadence. What meetings is the venture currently running on what cadence, and what is the cumulative time cost. The cadences that founders most often carry past their usefulness are the standing meetings instituted at an earlier stage that everyone now privately considers wasteful but no one has cancelled. The audit asks: if we were starting the venture today, would we institute this meeting on this cadence with these participants. If the answer is no, the meeting is a candidate for cancellation.
The fifth category is vendor and tool relationships. The software the venture is paying for, the agencies it is engaged with, the consultants it has under retainer. Each is a candidate for review against current need. The vendors most often carried past their usefulness are the ones with annual contracts that auto-renew, plus the ones whose original sponsor in the venture has moved on and nobody owns the relationship.
What the audit produces
A typical hour-long audit, run on a venture that has not had one in two years, will surface between four and ten obsolete practices. The number is reliably high because the absence of a regular audit allows obsolete practices to accumulate. The first audit is always the most productive because the backlog is largest.
The output of the audit is a list with three columns. The practice. The current cost (in time, money, or attention). The proposed change (retire, modify, or escalate to formal review). The list is then prioritised by cost, and the top two or three items become the focus for the following month. By the next quarterly audit, those items have been actioned, and the audit picks up the next two or three.
This is how the discipline works in practice. Not as a single dramatic overhaul. As a steady sweep, run quarterly, that prevents the venture from accumulating the kind of obsolete-practice debt that catches founders in year four with a venture that is doing many things that used to make sense and no longer do.
The deeper pattern this discipline addresses
There is a deeper pattern underneath the audit, and it is worth naming.
Founders are biased toward addition. We add new initiatives, new hires, new tools, new markets, new channels. We are less biased toward subtraction. We rarely systematically remove the things that have stopped earning their keep, because removal feels like loss, and loss is psychologically more costly than the equivalent gain in clarity.
The venture that compounds over years is not the venture that has added the most. It is the venture that has subtracted the most ruthlessly, leaving only the practices, channels, hires, tools, and meetings that genuinely produce value. The Stay-Up phase ventures all share this trait, in my observation: they are leaner than younger ventures of the same revenue size, because they have been pruning longer.
The quarterly assumption audit is the structural mechanism that makes pruning happen. Without the structure, the founder’s bias toward addition wins every time. With the structure, the venture has a recurring forced moment to question what has accumulated, and the questioning produces the subtraction that the bias would otherwise prevent.
The week the discipline starts
If you have not run an assumption audit in the last quarter, the most useful thing you can do this week is to schedule the first one for next week, block an hour, and run it against the five categories. The first audit will be uncomfortable because the backlog is large. The second one, three months later, will be smaller and faster. By the fourth one, the audit is a routine forty-five minute exercise that surfaces two or three items per quarter and keeps the venture lean by recurring discipline rather than by occasional overhaul.
That is the move. Schedule the hour. Run the audit. Action the top items. Repeat in ninety days. The cumulative effect, over two years, is a venture that has shed the practices that were quietly costing it and retained only the ones that are still genuinely earning their place. That kind of leanness is not the result of brilliant founder instinct. It is the result of structural discipline applied on schedule, regardless of how busy any given quarter feels.
The brilliance is in the schedule.
