If you’re a non-technical founder, chances are you’ve been burned by flaky devs, vague timelines, or code that doesn’t match the prototypes. That’s exactly why we built a model designed for trust.

At Designli, we pair non-technical software founders with full-time, founder-aligned product teams. Software engineers, designers and product owners who don’t just speak code, they speak human. We guide you through every step with clarity, structure, and care.

How it works, and what we can build:

Starting from Scratch?

We turn your idea into a clickable, interactive prototype with a feature roadmap and estimates so you can align co-founders, test the market, or pitch investors before writing a single line of code. No dev required (yet).

Recovering from a Bad Build?

Our team audits your codebase, cleans up what’s broken, and builds a plan for a second launch you can trust. We don't start over, we step in and make it better, fast.

Scaling What You’ve Built?

We help you scale with purpose. That means feature roadmaps tied to real metrics and user insights, not gut instinct or guesswork.

Each path begins with a dedicated product team assigned full-time to your project. Whether you need a prototype, a clean codebase, or a smarter scaling strategy, we’ll guide you there with clarity, speed, and craftsmanship you’ll be proud of.

Hi there,

I work as a fractional product manager with early-stage and growing teams.

I help founders and product leaders with:

product strategy and prioritization

product execution

AI integration

This is usually helpful when teams need senior product thinking but don’t want to hire full-time yet.

If product direction or execution is something you’re actively thinking about, happy to share how I typically help teams in similar situations.

Would it make sense to have a short conversation?

Best,

Priyal Jain

Fractional Product Manager

WeFlair is a Growth Marketing Agency that helps B2B SaaS, fintech and ecommerce companies turn fragmented growth activity into measurable revenue systems.

We work with founders, CMOs and Heads of Revenue at companies between €1M and €50M who have product-market fit and existing demand, but need the operating layer to scale acquisition, retention and pipeline efficiently. Most engagements start when paid acquisition is leaking, outbound has stopped producing meetings, or the data isn't telling the team what to fix next.

Where we work:

Paid acquisition — Google, Meta, LinkedIn and PMAX rebuilt around commercial intent, clean attribution, and lead-quality optimization tied to close rates rather than CPL.

Outbound and pipeline systems — ICP and TAM mapping, signal-based prospecting, list infrastructure, multi-channel sequencing, deliverability and reply classification across Clay, Apollo, Instantly and n8n.

RevOps and attribution — HubSpot, Salesforce, GA4 and reporting layers that show where pipeline, revenue and wasted spend are actually coming from, and what to change next.

CRO and ecommerce growth — Conversion, retention, lifecycle and personalization work that increases the value of existing traffic and customer base.

Recent results:=

→ €100M+ pipeline visibility surfaced for a $50M ARR enterprise payments platform

→ £4.5M incremental annual revenue for a global B2B ecommerce distributor

→ £1.3M revenue generated through a DTC fashion referral acquisition engine

→ 5.53x ROAS on paid social for a DTC sports brand

→ +130% deal volume for a B2B logistics business

How we work:

We operate as an embedded partner, not a vendor. Engagements typically run three to twelve months and combine system build, hands-on execution and team enablement, so the work compounds inside the business after we step back.

If you've outgrown tactical agencies and need someone who understands the operating layer, we should talk.
