Honest comparison for India performance-marketing buyers. Different models, different trade-offs. No fake tables — just the criteria that decide who’s right for your brand at your stage.
iProspect (Dentsu-group legacy performance agency, ~200+ India, global footprint) is the right call for Fortune 500 / large listed brands running ₹20 lakh+/month in ad spend, with governance-driven agency selection, integrated Dentsu media-buying at group rates. Strong global data + tech stack.
ITD GrowthLabs (senior-led boutique studio, Mumbai HQ, 55+ practitioners) is the right call for D2C + growth-stage B2B brands at ₹5–100 crore ARR who need performance marketing integrated with the rest of their growth stack — not run in isolation by a media buyer. Same senior owner from strategy through weekly execution. 100+ D2C brands, ₹8Cr+ ad spend managed.
The core trade-off: iProspect gives you legacy-agency scale + Dentsu media ecosystem + governance certification. ITD gives you senior time-on-account, faster iteration, integrated growth stack, and 40–60% lower total cost for equivalent performance-marketing scope.
Honest assessment per criterion — some iProspect wins, some we win. Pick the model whose trade-offs match your situation.
| Criterion | iProspect (Dentsu) | ITD GrowthLabs |
|---|---|---|
| Agency shape | Legacy performance agency (Dentsu group) | Senior-led boutique growth studio |
| Team size | ~200+ across India, global footprint | ~55+ senior in-house + specialist network |
| Best-fit buyer | Fortune 500 / large listed brands | D2C + growth-stage B2B at ₹5–100Cr ARR |
| Pricing model | Base retainer + 10–15% of ad spend | Flat retainer, no % of ad spend |
| Retainer entry point | ~₹4–6 lakh/mo per relationship | ₹40K/mo single-channel; ₹1.5–5L/mo full retainer |
| Engagement owner | Senior wins pitch → AM runs day-to-day | Senior who won pitch = senior who runs it |
| Integration with growth stack | Performance only — hand-off elsewhere | Integrated: paid + SEO + WhatsApp + email + creative |
| Media buying scale | Dentsu group rates on Google + Meta | Direct rates — standard for our volume |
| Iteration speed | Slower — specialist team hand-offs | Faster — senior owner has authority to ship |
| Reporting cadence | Monthly + quarterly | Weekly + monthly + on-demand |
| D2C specialisation | General — all industries | 12 D2C verticals with dedicated playbooks |
| Best for pipeline vs brand | Optimised for brand-level KPIs | Optimised for revenue + pipeline metrics |
We say no to bad-fit work because that’s how 97% retention is built. If your situation matches one of these, iProspect will serve you better.
Your procurement team requires a top-3 performance agency short-list. Your CMO’s board expects a name-brand agency partner. Your finance team wants Dentsu-level audit trail. These are legitimate reasons iProspect gets picked — and we won’t clear those checkboxes.
You’re running national campaigns at Rs 30–100+ lakh/month ad spend across Meta, Google, YouTube, OTT. Dentsu group rates + programmatic tech + specialised media teams give a real edge at this scale. Boutiques like us aren’t set up for that.
You’re running the same integrated performance campaign in 8–15 countries with local optimisation. Dentsu’s global network is the right footprint. Boutique India-focused agencies can’t replicate that.
These are the engagements we say yes to most often. If your situation matches one of these, the math (and the calendar tax) favours us.
You’re past MVP but not yet a listed giant. You need performance marketing integrated with SEO, WhatsApp, creative, and web — not five vendors coordinating hand-offs. We ship all of that under one senior owner.
Your board reviews you on qualified leads, MQL cost, blended CAC, revenue — not GRPs and impressions. Our ₹8Cr+ ad-spend track record is on pipeline outcomes. Our Ready-to-Buy lead-gen framework is built for accountable growth marketing.
You want the practice lead reviewing creative + tuning campaigns, not an account executive translating between you and a search team. Our senior owner has 4–6 accounts, not 15.
You dislike the “we make more when you spend more” incentive of % of ad spend. Our flat-retainer model aligns us to make YOUR business efficient, not our billings big.
Your landing pages take 3 weeks to ship, your marketing agency and dev shop don’t talk. We do both — growth marketing AND custom web/apps — from the same team. Faster to production.
You’re at the stage where the CFO scrutinises retainer + commission cost. We typically deliver equivalent scope 40–60% cheaper because there’s no layered specialist team hand-off.
iProspect: base retainer + % of ad spend. ITD: flat retainer, no % of ad spend. At higher spend levels the gap widens dramatically.
| Line item | iProspect (indicative) | ITD GrowthLabs |
|---|---|---|
| Base retainer | ₹6 lakh/mo | ₹3.5 lakh/mo |
| Agency commission (@ 12% of ₹20L) | ₹2.4 lakh/mo | — |
| Creative production | Add-on / separate SoW | Included |
| SEO + email + WhatsApp | Not typically included | Included |
| Agency cost (ex-ad-spend) | ~₹8.4 lakh/mo | ₹3.5 lakh/mo all-in |
Bands are indicative from India performance-agency market research (2024–2026) & our own quotes vs known iProspect engagements. Actual quotes vary with brand size, scope, industry regulation, and delivery footprint. Both firms scope + quote formally on discovery.
These are the questions we hear on discovery calls when the buyer has already talked to an iProspect account team.
If iProspect is the better fit for your brand stage or governance profile, we’ll say so. If we’re a better fit, we’ll scope + quote on the call. No pitch deck, no sales script.
