A GTM diagnostic for D2C brands, and the five numbers it starts with
Your go-to-market plan is the part of the business an investor will test hardest, because it's where their money goes. A GTM diagnostic checks whether the way you find, win and keep customers can carry more spend without the economics falling apart.
For an early-stage consumer brand in India, that question usually comes down to five numbers. We start every GTM read with them, and you can work them out yourself before you speak to anyone.
1. Contribution margin on the first order
Take the selling price after discount. Subtract product cost, packaging, shipping, payment gateway fees, the cost of returns and RTO (return to origin, which hurts cash-on-delivery brands badly), and the ad spend it took to win that order. What's left is your first-order contribution.
It's often negative, and that's allowed. What matters is whether you know the number and whether it's getting better or worse. A brand that loses ₹180 on the first order and knows exactly how it earns that back by order three is in a far stronger position than one that "roughly breaks even" and can't show the working.
2. Payback period by cohort
How many days until a customer's gross profit covers what you spent to acquire them? Work it out separately for each month's new customers, not as one blended average. If January's customers paid back in 70 days and June's are on track for 140, something changed in your targeting, your pricing or your product mix, and a fund will spot it in your data before you mention it.
3. Channel mix and what each channel really costs
List every channel that brings in revenue. Your own site, Amazon, Nykaa, Flipkart, quick commerce, modern trade, offline distributors. Next to each, write down what it costs to sell there once commissions, ad fees, listing fees, margins to distributors and settlement delays are counted.
Founders are often surprised by this list. A quick commerce channel that looks like 25% of revenue can carry the lowest margin in the business once listing and visibility fees are in. That doesn't mean leave it. It means know why you're there.
4. Repeat rate at 90 days
What share of first-time customers buy again within 90 days? For consumables like coffee, protein or daily skincare, this number does more work than any other in your deck, because it tells an investor whether growth compounds or has to be bought fresh every month.
If your category has a long natural repurchase cycle (a fragrance, a cookware set), use the cycle that fits your product and say why. Investors respect a founder who picks the right window and explains it.
5. Spend at which the numbers break
Every acquisition channel gets more expensive as you spend more on it. The question a fund is really asking is how far you can push spend before cost per order rises past what a customer is worth. If you've never tested this, say so and show the plan to test it. A guess dressed up as a forecast is easy to spot.
Reading the five together
One number on its own rarely tells the story. A brand with a 32% repeat rate and a 160 day payback is a different business from one with a 12% repeat rate and a 40 day payback, and they need different plans. The first can afford to spend on acquisition and wait. The second should spend less on ads and more on getting the second order.
The diagnostic puts the five side by side, finds the one doing the most damage, and turns it into a short list of changes, ranked by how much they move the business and how hard they are to make.
What a GTM diagnostic isn't
It isn't a marketing agency audit of your ad creative, and it isn't a brand strategy deck. We don't run your ads. We look at whether the plan behind them holds up when an investor reads it, and we help you fix the parts that don't.
It's also part of a full venture diagnostic, not a separate product. Go-to-market is usually where the biggest problems sit, so it's where we start.
Next step
Work out the five numbers above for your brand. If two or more are blank, or you aren't sure which one is hurting you, start a readiness conversation. We'll tell you plainly whether a diagnostic is worth it right now.
Questions
FAQ
I don't have clean cohort data. Is it still worth doing?
Yes. Getting cohort data out of your store and ad accounts is often the first piece of work, and once it's built you keep it.
We sell mostly on marketplaces. Does this still apply?
It applies more. Marketplace brands have less customer data and thinner margins, so knowing the five numbers matters even more.
Do you look at offline and modern trade?
Yes, including distributor margins and payment terms, which is where cash often gets stuck.
