Research and outreach assistant for an AI startup

What we do Assay verifies how good developers actually are at building with AI. They take timed challenges, the work is graded automatically and by a human reviewer, and companies hire from a ranked list. The product is built and running; you can click through it here: [demo link]. What I need I'm the founder and I'm doing everything myself. I need someone reliable to take the research and first-contact work off my plate, starting with a small paid trial and continuing at 10-15 hours a week if it goes well. Three streams of work: 1. Finding developers. Building a list of senior freelance engineers who match a written spec (TypeScript, LLM evaluation work, Bittensor experience for one role), from GitHub, LinkedIn and developer communities. Writing short personalised first messages, tracking replies, and booking calls in my calendar. 2. Finding companies to talk to. Building a list of early-stage startups and agencies building AI features, finding the right person at each, and sending a short first message to book a 20-minute call with me. 3. Research support. Building a contact list of investors with details like fund, cheque size, recent investments and any mutual connections. Research only: I write and send all investor messages myself. What good looks like • 20 well-researched, correctly-targeted contacts beat 200 scraped ones. I will check. • Every message references something specific and true about the person, not a mail merge that says how much you loved their work. • One shared spreadsheet, always current, so I can see status without asking. • A short weekly summary: sent, replied, booked, and what you think isn't working. You'll be good at this if • You've done sourcing, lead generation or research support before, and can show what you produced. • You write clear, plain English, and can write a two-sentence message that sounds like a person. • You're comfortable with LinkedIn, GitHub, Google Sheets and a mail tool. • You ask when a brief is unclear instead of guessing. Technical background isn't needed. Interest in how people are hired for AI work is a plus, because you'll be reading a lot of profiles. How this works Start with a paid trial: 5 hours, £[amount], from a task I'll send. If it goes well, ongoing at 10-15 hours a week, reviewed monthly, with more hours available if you want them. Choose your own working hours, with one short call a week at a time that suits us both. To apply Please answer the four questions below in your proposal. I read every proposal that answers them, and I reply either way. 1. Describe one sourcing or lead-generation project you ran. How many contacts, from where, and what came of it? 2. Here is a person I'd want to contact: https://www.linkedin.com/in/andrewyng/. Write the two-sentence first message you would send them on my behalf. 3. How would you find senior TypeScript developers who have worked on LLM evaluation? Name the specific places you'd look. 4. How many hours a week can you commit, in which timezone, and what's your hourly rate?

B2B salesperson for Software — paid pilot + referral commission

We’re looking for a salesperson who can introduce SandboxCMS to web agencies, WordPress, Prestashop, drupal developers, and teams that regularly test CMS sites or online stores. SandboxCMS lets users launch working WordPress, WooCommerce, Drupal, Joomla, and PrestaShop sandboxes without setting up hosting. You can see the product at sandboxcms.com. We’ll agree on a target customer and outreach approach before work begins. At the end of the pilot, please deliver a list of prospects contacted (or anything that can help us track your prospects), your outreach activity, replies. We’ll provide product information and a unique referral code to track your results. If you deliver good results, we’ll pay **25% of payments received from customers you bring in during their first six months**, subject to an agreed referral and refund policy. Commission will be paid through PeoplePerHour. Our initial goal is to find customers suited to the Business plan (€60/month), particularly agencies managing multiple test sites. If the pilot produces promising conversations or sales, we’d like to continue working together. When applying, please share your experience selling SaaS to agencies or developers, who you would approach first, and how you would reach them.

Client-Facing Software Developer – Interview & Meeting Support

We are looking for a software developer with strong communication skills to join our team. This is a client-facing role where you will represent our development team during interviews and project meetings. In this role, you will: Join client interviews and meetings via video call (Zoom/Google Meet). Explain technical concepts clearly to clients and stakeholders. Participate in architecture reviews and sprint syncs as a technical representative. Maintain a high level of professional communication aligned with U.S. business standards. This is not a coding role. Your primary focus is on professional communication. However, a solid technical background is required to understand and explain architecture, development processes, and technical decisions. Requirements: 3+ years of experience in software development or a related technical field. Strong spoken and written English communication skills. Confident and professional on video calls with clients. Ability to explain complex technical ideas clearly. Experience with modern tech stacks (React, Node.js, Cloud Infrastructure, etc.) is a plus. Availability during U.S. business hours. Compensation: $40–$60/hour (estimated). This is a part-time, ongoing freelance role. Payment is processed securely through PeoplePerHour. How to Apply: Please submit your application including: 1. A brief summary of your technical background. 2. Your experience with client or stakeholder communication. 3. A short video introduction (2–3 minutes) explaining your technical background and communication experience. This helps us quickly assess English communication skills for this client-facing role.

Finalize Flutter Media App Part-Time Flutter/Node Developer

Global Kirtan App (GKA) is a non-denominational platform for kirtan, sacred sound, and bhakti practice, built for a global audience spanning devotional practitioners, yoga communities, sound healers, and spiritual-but-not-religious users. It's a freemium mobile app combining regular practices, audio/video streaming, a lyrics library with translations, tutorials, event discovery (map + calendar), facilitator and community profiles, and an instrument shop. This isn't a from-scratch build. A working Flutter app already exists with a live backend, and it's been through an independent technical audit — we know its real strengths and its real problems. We're looking for a developer to pick it up from here. The Role This is deliberately not a full-time position, and we can't offer at this time. What we're looking for instead is someone willing to become our standing point of contact for this codebase — available reliably when work comes in, understanding upfront that hours will vary month to month and neither side is committing to fixed employment. If you need guaranteed steady hours, this probably isn't the right fit; if you're comfortable with an ongoing, flexible working relationship and want to be the person who knows this app inside out over time, it might be exactly right. There's no guarantee here — but a developer who proves reliable and becomes a genuine fit for this project would be our first call for full-time or expanded part-time work, once we're actually in a position to offer it. First phase — roughly 20 hours: • Fix the known issues from our existing audit. • Begin work on a new Practice tool — a planned addition to the app's core navigation. Full specification shared once we've agreed terms. After that — ongoing, unpredictable: • Common maintenance tasks • Bug fixes, small feature additions, dependency and security updates, as they come up • Some months will be quiet, others busier — we're looking for someone who can flex with that rather than needing a fixed retainer Compensation Compensation is set at Indian developer market rates. Whether we structure it as hourly or fixed-per-requirement will be decided together based on what makes sense for each piece of work — we're open to either. Confirmed Tech Stack Mobile app (Flutter/Dart): flutter_riverpod (state management), go_router (navigation), dio (networking), just_audio + audio_service (media playback and session handling), youtube_player_iframe (embedded video), flutter_map, flutter_secure_storage (encrypted credential storage). Release builds use R8 obfuscation and are properly signed. Backend (as specified): Node.js + TypeScript modular monolith, PostgreSQL, versioned REST API (/api/v1/), JWT-based authentication. What We Need From You • Real, demonstrable Flutter/Dart experience — ideally including audio or media-heavy apps • Comfort inheriting and working inside an existing codebase, not just building greenfield • Honest communication about your own actual availability — we'd much rather hear "I can only do a few hours some months" upfront than have someone overcommit and go quiet later • A genuine interest in an ongoing relationship with this project, not a single ticket — we're picking a person to grow with the app, not just closing a task • Comfortable working respectfully with devotional and sacred content across multiple traditions • Willingness to sign an NDA and assign IP (Intellectual Property) ownership of delivered work to us How We'll Work • Full Git repository access, normal commit/PR discipline • We'll share our existing independent technical audit with serious applicants (under NDA) so you know exactly what you're inheriting before committing to anything • Payment structure and rate agreed in writing before the first task begins To Apply, Please Share 1. Flutter/mobile projects you've built or maintained, especially anything involving audio/media playback 2. Your honest, realistic read on your own availability over the next 6–12 months 3. Any experience picking up and maintaining someone else's existing codebase (not just building your own)

Investor Pitch Deck Designer for Consumer Tech Startup

We are looking for an experienced investor pitch deck designer to create a new fundraising deck from scratch for Toggle, an early-stage consumer technology startup. Toggle is developing a physical product and companion platform designed to help people deliberately put their devices down together and create more opportunities for real-world connection. We have developed the proposition, product concept, brand, commercial model and fundraising strategy, and can provide all of the underlying information, imagery and supporting material. What we are looking for is someone who brings genuine investor pitch-deck expertise, not simply graphic design skills. We want you to help determine how the story should be structured, what an investor needs to see, what should be prioritised, what should be removed, and how the narrative should flow. We do not want to prescribe the number or order of slides, we want your expertise to guide that. Visually, we are looking for something premium, minimal and confident, with the simplicity and discipline associated with high-end consumer technology presentations. Strong typography, space, varied layouts and powerful use of product/lifestyle imagery where appropriate, rather than a conventional corporate PowerPoint aesthetic. We are currently preparing to raise £300,000 through SEIS and have Advance Assurance. We can provide our existing materials as background information only, but this should be treated as a completely new deck rather than a redesign of an existing presentation.

Experienced AI (Outbound) Telemarketer

I have been managing outbound telemarketing teams in the UK for over 20 years, up until 2024, and have developed and taught a highly structured sales process that has been very successful. Over the past few months, I have been working towards rebuilding our direct sales operation without the challenges and management requirements associated with running a traditional telemarketing team. Our primary objective has been to develop an AI outbound telemarketer that can replicate our structured sales process and deliver conversations to the required standard. Unfortunately, two different developers have attempted the project but have been unable to achieve the level of accuracy, timing, responsiveness and natural conversation flow required. The current system is approximately 98% complete and the dashboard and backend are already in place. We are currently using Twilio and ElevenLabs. I believe the remaining issues can be resolved by someone with the right specialist experience in AI voice agents, telephony integration and real-time conversational systems. Before we arrange a meeting, we would like you to review the project materials, including: 1. The written sales pitch, which follows our structured 5-step methodology. https://docs.google.com/document/d/186JBo-MP2vTrKIwRyYD3minFKSU8JOisCAX2y-AMcDU/edit?usp=sharing 2. A verbal role-play recording demonstrating how the pitch should be delivered. https://drive.google.com/open?id=1ldPRd-8Dcfc6v1zg7qEyDISqXZ4a8gmg We would like to hear from developers who have genuine experience in building and optimising outbound AI telemarketing or conversational voice systems. When responding, please provide: * Examples of relevant AI voice or outbound telemarketing projects you have completed. * Details of your experience with Twilio and ElevenLabs. * Examples of systems where you have resolved issues involving response timing, latency, accuracy or conversational flow. * Links to relevant work, demonstrations or case studies, where available. * A brief explanation of how you would approach reviewing and improving an existing system that is approximately 98% complete. We are specifically looking for someone with proven, relevant experience rather than someone learning or experimenting with AI voice technology for the first time. Please review the written pitch and verbal role play before responding. We look forward to receiving your review and examples demonstrating your relevant experience. Due to the number of enquiries we receive, we will not respond to applications that do not include relevant examples of previous work and experience. The payment stated is not relevant. Regards Proactiv
