Who we are

Bintime is a Dutch-founded technology company with 20+ years in commerce. We work with retailers, marketplaces, and technology-led businesses on three fronts:

• Services (our primary revenue motion). Senior engineering teams embedded as long-term augmentation or as delivery pods with outcome ownership.
• Gepard. AI-native product data platform — ingestion, enrichment, syndication, and regulatory compliance.
• B-Hive. Multi-agent AI platform for retail operations — customer support, product discovery, and shopping experience.

You can read more at bintime.com, gepard.io, and b-hive.io.

The job, simply

You own Bintime's marketing funnel. Every lead source — SEO, Google Ads, LinkedIn, YouTube and video, Clutch, events, partnerships, content — runs through you. Your job is to turn website visits and outbound impressions into form submissions and booked calls that Sales qualifies as real deals.

You are not building a marketing department this year. Freelance designers, writers, and video editors are available to activate on brief, but the direction and the outcomes are yours. If things go well and pipeline justifies it, a team gets built around you in year two.

You report to the Head of Sales and work closely with the CEO, Sales, and product leads for Gepard and B-Hive. Services gets the majority of your focus; Gepard and B-Hive are secondary wedges you support alongside.

What success looks like

Three numbers, every month:

• Form submissions and booked calls. Measured in HubSpot, tagged by source. A target gets set with you in month one and raised quarterly.
• Sales-accepted qualified leads. Sales confirms the lead is worth their time. If Sales does not accept it, it does not count toward the number.
• Marketing-sourced closed-won revenue. The number that matters most. Tied to HubSpot deal attribution.

Supporting metrics (cost per lead, cost per qualified lead, channel conversion rates) exist to help you move those three numbers. They are not separate goals.

The lead sources you will own

All of the below, end-to-end. We do not use agencies; you set direction and execute, with freelancer help where useful.

Source

What owning it looks like

SEO - Keyword strategy, technical health, on-page, content clusters, backlinks. Measured by qualified organic traffic and form submissions from organic.

Google Ads - Search and retargeting campaigns, landing pages, conversion tracking, budget decisions.

LinkedIn (organic + paid) - Company page, executive posting support for CEO and Head of Sales, LinkedIn Ads campaigns, event and lead-magnet promotion.

YouTube and video - Channel strategy, production coordination with freelance editors, demo videos for Gepard and B-Hive, case studies for Services, short-form for LinkedIn.

Clutch and review sites - Profile buildout, review collection process, ranking for target categories.

Events - Pre-event demand gen, landing pages, onsite content, post-event nurture campaigns.

Content engine - Blog, case studies, gated lead magnets (benchmark reports, audits, checklists), webinars. Every piece produced with a conversion purpose.

Partnerships - Joint webinars, co-authored content, cross-promotion with complementary vendors. Executed with Sales and BizDev.

Website and landing pages - bintime.com, gepard.io, b-hive.io, campaign LPs. Forms, CTAs, conversion testing, tracking.

Email nurture - HubSpot sequences that move inbound leads from form fill to booked call. Conversion flows, not newsletters.

How you work with Sales

Marketing and Sales share HubSpot. Sales also runs outbound in parallel through a team of SDRs. Your role is to make this one funnel, not two. In practice:

• Weekly sync with the Head of Sales — what shipped, what moved, what Sales needs next
• You produce outbound-supporting assets (case studies, landing pages, benchmark reports, demo videos) on the SDR team's brief
• You qualify form submissions against fit before routing to Sales — volume that does not convert helps nobody
• Sales gives you back every week: which leads converted, which failed, why. You use that signal to adjust sources and messaging
• One HubSpot dashboard both functions read from. No separate marketing-only numbers

Budget

You own the marketing budget and make the trade-off calls across channels. Starting allocation is agreed with the Head of Sales and CFO in month one, then reallocated monthly based on what the numbers show. Channels that produce qualified leads at acceptable cost get more; channels that do not get reduced or cut.

Expected paid spend starts in the €4K–€8K/month range, scaling with performance. Production costs (video, design, content) sit separately.

Tools you will use

Day-one fluent in HubSpot. Working comfort with most of the rest:

• HubSpot Marketing Hub + Sales Pro — campaigns, forms, workflows, attribution, reporting
• Google Ads and LinkedIn Ads
• GA4 and Google Search Console
• Ahrefs, Semrush, or similar for SEO
• Webflow or another CMS for website edits
• LinkedIn Sales Navigator for account targeting
• Clutch and G2 consoles for review-site management
• Claude as core LLM 
• Figma for design review
• Trello and Google Drive

Who we think will do well here

We are less interested in a specific years-of-experience number than in what you have actually done. If most of the below sounds like you, apply:

• You have run measurable B2B demand generation before and can point to campaigns you owned and what they produced
• You have hands-on experience across at least four of: SEO, Google Ads, LinkedIn Ads, YouTube or video, email nurture, review sites, events, landing page conversion. Not "managed an agency that did it"
• You operate HubSpot at a builder level — forms, workflows, lead scoring, attribution. Not just end-user
• You write clear, English - В2. This role produces a lot of copy
• You are comfortable reading and arguing about numbers — cost per lead, conversion rates, attribution

Nice to have:

• Experience marketing a B2B services business, not only SaaS
• Clutch or G2 presence building that moved real pipeline
• Worked alongside an outbound SDR team before and with Sales for the basis of marketing activities to be delivered. 
• Familiarity with eCommerce, retail tech, or PIM ecosystem

A note

We know this list looks long. If you meet most of it and the rest you are willing to learn quickly, please apply. We would rather hear from someone strong with gaps than miss them because the list read as a wall.

Working conditions

• Full-time, 
• Direct report to the Head of Sales
• Compensation: base plus a performance bonus tied to marketing-sourced qualified leads and closed revenue. Range is set based on market research and finalized with the candidate
• Path to Head of Marketing in 12–18 months if pipeline contribution supports building a team

What we offer:

• Bintime Academy: Internal university for professional development

We’re looking for a Chief Executive Officer (CEO) to take full ownership of one of AIBY’s core product groups — a 20M-install, $10M ARR consumer subscription business — and scale it into its next phase of profitable growth.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization
• Growth & Monetization: work hand-in-hand with your UA Lead to optimize ROAS (Return on Ad Spend) and Payback Periods. You’ll oversee the subscription funnel, A/B testing, and paywall optimizations
• Cross-Functional Leadership: build, structure, and scale a high-performing team across Product, Growth, Marketing, Engineering, and Design
• Resource/ Capital Allocation Strategy: you have the autonomy to decide where to “bet” your resources. If a specific app in your unit is scaling, you pivot the team’s focus there immediately
• Partnership with the Board and Founders: you’re involved in strategic decision-making at the C-level, with direct impact on business metrics, financial results, and the product ecosystem

What you should have:

• 7+ years of experience in product-based B2C businesses (subscription, mobile/web)
• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

Location

AIBY is a team of strong international top talents. This role allows for either hybrid (combining in-office and remote work), fully remote or in-office work.
